• Question about Equallogic snapshots.

  Hello forum

  I could not confirm this, but instant never need to commit anything to the basic volume?

  Lets say I have 10 snapshots and delete the oldest? There will be a load of e/s to validate these instant changes?

  Also, if someone could point me to any type of indepth explanation of this technique of snapshot, I would be interested to read all that.

  Thank you!

  N ° current data are already on the base volume.  There is nothing to commit.   Only if you are completely restoring a volume from a snapshot will be there in writing for the base volume.

  Solution title TABLE: how the snapshot reserve space is allocated and used

  Solution details Snapshot Reserve Allocation and use

  -------------------------------------

  In a series group PS, snapshots can protect against errors, of a volume

  virus or the database. A cliché represents the content of a volume

  at the time you created the snapshot. Creating a snapshot does not disturb

  access to the volume, and the snapshot is instantly available allowed

  iSCSI initiators.

  Before you can create snapshots for a volume, you must allocate space (called

  snapshot pool) for snapshots. You set the value of the snapshot reserve

  When you create or modify a volume. Snapshot reserve benefits from the same

  as the volume of the pool data.

  When snapshot data consume entire supply snapshot, the Group remove is

  the oldest snapshots to free up space for new images or sets the volume and

  snapshots offline, according to the policy you selected for instant recovery

  space.

  The functionality for creating snapshots is called hybrid allocate when writing.

  Operation of sharing and snapshot of the page

  -----------------------------------

  A PS Series Group organizes the physical storage into logical segments called pages.

  Each page is composed of several logical blocks. This is similar to the way file

  systems combine areas of physical disk in 'clusters' or 'chunks '. Each page has

  a reference count which records the number of volumes and snapshots that share

  the page.

  When you create a volume, the group creates an internal table, called the volume

  table, which contains pointers to pages that use the volume. When you create

  a snapshot of a volume, the group creates a snapshot table by making a copy of

  the volume table, which is usually an operation in memory that the Group

  run in a transactional manner. For each page of volume in use, the support group increases the

  reference count to indicate that the volume and the snapshot share page.

  Because the group does not move or copy the data or allocates a new pages, photos

  are fast and efficient.

  Reserve of the snapshot stores the differences between the data on the volume and snapshot data

  (in addition to differences between the data of multiple snapshots). When you

  first create a snapshot, the page for the volume and the snapshot tables are

  In brief identical copies and the snapshot consumes no snapshot

  reserve. A reading of the same logical block of the volume application or the

  snapshot returns the same data because the application is reading from the same page.

  However, if you write a page that has a volume and a snapshot of share, snapshot

  reserve is consumed.

  Here's a simplified example of a snapshot operation. In general, no.

  additional I/o operations are needed to manage the data volume or snapshot.

  However, other internal operations can occur due to virtualization and

  data balancing on berries of the PS Series.

  If an application performs a write to 8 KB for a volume containing a snapshot, the

  Group:

  1. determine what page is modified by the write operation.

  2 - If the page is not shared, writes the data to the page.

  3. If the page is shared:

  . (a) allocates a new page of disk space and reduces the instant to reserve

  . the volume of a single page.

  . (b) update the page of volume table to point to the newly allocated page.

  . (c) mark the newly allocated page as having new data on the volume and the references of the

  . original page for unchanged data.

  . (d) writes the data to the new page.

  When writing is complete, if you read the data on the volume, you have access to the

  new page and new data. However, if you read the same logical block of the

  Instant, you get the original data, because the snapshot will always point towards the

  original page. Similarly, if you set a snapshot online, write to the snapshot.

  feature hybrid write protects the original data volume by allocating

  a new page for the new snapshot data.

  Only the first page of writing to a volume shared (or snapshot) consumes additional

  snapshot reserve. Each subsequent entry is considered identical to a writing on a

  non-shared the page because the original data are already protected.

  Functionality similar to hybrid allocate when writing is used in cloning operations.

  However, unlike when you create a snapshot, cloning a volume immediately

  consumes space additional group. If a clone is moved to another pool, data

  is copied during the operation of moving pool.

  Restoring a Volume from a snapshot

  ----------------------------------

  Because of the layout table, restore a volume from a snapshot is very

  quick. First of all, the group automatically creates a snapshot of the volume by copying

  the volume table to a new table of snapshot. Then the Group transposes the page tables

  the volume and the snapshot you selected for the restore operation. NO.

  additional space is required, and no data is moved.

  Deletion of Volumes and Snapshots

  ------------------------------

  Because volumes and snapshots to share pages, if you delete a volume, you

  automatically remove all the clichés associated with the volume.

  You can manually delete snapshots (for example, if you need more of)

  snapshot data). In addition, the group can delete snapshots automatically in the

  following situations:

  1 - failure instant free reserve. If the snapshot data consume the snapshot

  . reserve, the group either deletes the oldest snapshots to free up space for new

  . snapshots or sets the volume and snapshots in offline mode, according to the policy

  . you have chosen for the snapshot space recovery.

  2 - maximum number of snapshots, created from an agreed timetable. If you set up a

  . timetable for the creation of snapshots, you can specify the maximum number of

  . photos you want to keep. Once the program creates the maximum number

  . clichés, the group will delete the oldest snapshot for planning

  . to create a new snapshot.

  Snapshot are deleted in the background queue. The group travels

  the snapshot page table and decremented the reference count on every shared page.

  Any page that has a zero reference count is released into free space. Pages

  with a zero reference count are not released because they are shared with

  the volume or other snapshots.

  Because stereotypes can be automatically deleted, if you want to keep the

  given to a snapshot, you can clone the snapshot.

  Reserve snapshots use agreement

  ------------------------------------

  The snapshot reserve is consumed only if you write a shared volume or snapshot

  page. However, it is difficult to establish a correlation between the amount of data written in one

  volume (or snapshot) with the amount of instant reserve consumed as a result.

  especially if you have multiple snapshots.

  Because the pages consist of several logical blocks, size e/s and distribution

  volume merge affect overall performance of e/s in addition to the snapshot

  reserve its use.

  For example, do much written about a narrow range of logical blocks in a volume

  consumes a relatively low amount of reserve of the snapshot. This is because as Scripture

  the same logic block more than once, does not require not additional snapshot

  reserve.

  However, doing random number wrote a range of logical blocks in a

  volume can consume a large amount of reserve of the snapshot, because many other

  pages are affected.

  In general, use instant reserve depends on the following:

  1. number of entries that occur in the volume (or snapshot) and at least one

  . snapshot exists. In general, more Scriptures tend to use more snapshot reserve.

  . Although multiple writes to the same logical block do not require additional

  . space.

  2 - the range of logical blocks, on which occur the Scriptures. Written in a wide range of

  . logical blocks tend to use more instant reserve written in a narrow

  . rank, because more of the written word are to different pages.

  3. number of snapshots of the volume and timing of the write operations. Most

  . snapshots that you create more snapshot reserve is necessary, unless there is

  . few entries on the volume or snapshots.

  4 - age of snapshot. Snapshots older tend to consume more snapshot reserve only

  . the clichés of recent because the group must retain the original data for a

  . longer time.

  Design Snapshot reserve

  -----------------------

  You cannot create snapshots until you book instant space. Snapshot reserve

  is set as a percentage of the reserve volume (space) for the

  volume.

  When you create a volume, by default, the volume uses instant group-wide

  reserve adjustment. (The reserve in the scale default setting is 100%. You

  can change this default value.) You can change the reserve snapshot setting when you

  create a volume or later, even if the volume is in use.

  Although the snapshot reserve is not used until the volume or writing snapshot occur, it

  is consumed immediately free pool space. For example, if you create a

  fully allocated (not thin provisioned) 200 GB volume and specify a snapshot of 50%

  pool of reserve, free space is immediately reduced to 300 GB (200 GB for the volume

  reserve and 100 GB for Snap reserve), even if there are no pages in use.

  Therefore, before you create a volume, you should consider how many snapshot

  reserves, if any, to assign to the volume. The reserve of the snapshot set to zero (0)

  If you do not want to create snapshots.

  The optimal size of the snapshot reserve depends on the amount and type of

  changes in the volume and the number of shots you want to keep.

  By example, if you set the snapshot reserve 100%, and then create a snapshot.

  You can write to each byte of the volume without missing snapshot

  reserve. However, if you create another snapshot and then write in each byte of

  the volume, the first snapshot is deleted in disk space available for the new snapshot. If

  you set the instant reserve at 200%, there would be a sufficient reserve of snapshot

  for the two snapshots.

  A very conservative strategy in terms of instant reserve sizing is to put the snapshot

  book value at 100 times the number of shots you want to keep. This

  guarantees that keep you at least the number of snapshots, regardless of the

  the number of entries on the volume. However, this strategy is generally allocates

  book an excessive amount of snapshot, because that rarely crush you all the

  the data in a volume during the lifetime of a snapshot.

  The best way to instant size reserves is to assign an initial value to the reserve

  and watch how instant you can keep over a period of time specified under a

  normal workload. If you use tables to create snapshots, allow the

  calendar of work for several days.

  To get an initial value for a snapshot reserve volume, you must estimate

  the quantity and the type of entries in volume and the number of snapshots, you want

  keep. For example:

  -If you wait a few Scriptures or writings which are concentrated in a narrow range

  . logical blocks and you want to keep only a few shots, start with a value

  . 30%.

  -If you wait several entries or entries that are random in a wide range of

  . logical blocks and you want to keep more than a few shots, start with a value

  . 100%.

  If the snapshots are deleted until you reach the desired number of snapshots,

  increase the percentage of snapshot reserve. If you reach the desired number

  shots without consuming much of the instant free reserve, decrease the

  percentage of reserve snapshot. Continue to follow instant reserve and

  adjustments as needed.

  How Thin Provisioning button Snapshot Reserve

  ----------------------------------------------

  The snapshot reserve is based on a percentage of volume reserve (allocated space

  a volume). For a volume fully provisioned, the reserve volume is equal to the

  stated volume size. However, a thin volume put into service, the volume of reserve

  is initially very inferior to the reported size (default is subject to minimum volume

  10% of the reported size) and increases as the written volume occur.

  If you change a thin volume supplied in a volume fully provisioned, the

  amount of reserved snapshot increases automatically, because the volume of reserve

  increase in the size of the stated volume.

  If you change a volume of fully provisioned to thin-provisioned, the amount of

  snapshot of reserve decreases automatically, because the volume of reserve declines.

  However, if the snapshot resulting reserves will be too small to store all the

  existing snapshots, the group will automatically increase the instant reserve

  percentage of value that preserves all existing snapshots.

  Reducing the use of instant reserve

  -------------------------------

  Over time, you can reduce the use of instant reserve by periodically (for example,

  Once a month) defragmentation of databases and file systems. Defrag operations

  try to consolidate segments of files in a volume and, consequently, to reduce the scope

  logical blocks addresses used in the pages of the volume.

  Defragment the data read operations from one place and then write data to a new

  location. So increased use of instant reserve during and immediately

  after defragmentation, because existing snapshots will use more of the usual

  amount of the snapshot reserve. However, snapshots created after defragmentation

  operation must use less instant reserve, because the data on the volume are more contiguous.

  When a volume is highly fragmented, potential reduction of the snapshot reserve

  use can be dramatic, especially after removing the large before you defragment

  snapshots. Defrag operations can also reduce the I/O load on the group,

  because the contiguous data makes more efficient i/o operations, in order to improve the

  e/s overall performance.

  Latest defragmenters are good to reduce the fragmentation that is not seeking to be

  too thorough. Some defragmenters also try to combine the inactive data

  further restricting the likelihood of changes to shared pages. However, are not

  Defragment too frequently.

  Sector alignment may also affect the use of snapshot of the space, especially in

  larger volumes. File systems must be correctly aligned with the sector. It comes

  described in technical reports for VMware and Windows environments.

• Lumenera cadence

  Hello

  I use a camera Lumenera for my LabVIEW project. I download everything and it works fine except the cadence. In LuCam Capture, I can set the frame rate to 15,05 fps, fps 7.52, or 3.76 fps. How can we define this in LabVIEW? It takes more than 100 ms to make a quick glance (so I guess that the default setting is 7.52 fps) and I would do it faster. Here are the settings I can change for the camera:

  

  The exposure time is set to 5 ms and the delay of the exhibition is set to 0.

  Do you know how I can change the frame rate?

  Thank you

  Stephanie

  I contacted Lumenera. There is a VI called 'LuSetProperty.vi' and the setting is 'instant clock speed. The default value is 106, and if we put the value 0, it will be faster.

  I don't know why they haven't put it in the entrance of the snapshot settings...

  Thank you for all your help,

  Stephanie

• chart axes not without stage.show)

  Hello

  I do instant image accessible writing scene.  I see that, at least I have call stage.show () axes of the graph are not labeled.  I think just make graphic image files and not need to have the user interface for this treatment.  I am therefore able to generate graph with plotted data images but missing labels units of axes (values).

  Kind regards

  Miten.

  I guess you need to do a bit of the following before trying to capture instant card:

  1. create a scene and add a graphic to it (so that css is treated correctly).

  2. correctly configure snapshot settings to use for your snapshot (so that fills background etc. are well positioned).

  3. turn the animation off the graph (of the sort that the snapshot is not taken until the animation ends the display of the data).

  4. write your code in the start of a JavaFX Application subclass method (so that the JavaFX Toolkit is completely initialized, and you ask the rendering on the JavaFX application thread).

  My bet would be on point 3 being the cause of your problem.

  It is best to post the executable code with questions like this that someone can reproduce your problem.

• Modified while saving the edited original image

  Hello

  I'm an absolute beginner using Camera Raw.

  I just edit an image in Camera Raw 5.7. When I had finished, I saved the edited image using a new name. Unfortunately the original image has also changed. So now I have two identical edited images with different names, but the original image disappeared. How can I keep the original?

  Best regards, Nicole

  The original image is always there... He just had added to the raw file processing settings. If you really don't want them you can either go in Bridge, edit, develop settings and click clear. But if you do you will lose all the work you put into making the adjustments... you might be better to go back in Camera Raw and create a snapshot settings them you can reset the image to its default settings.

• Snapshots created with the EqualLogic VSS provider are not displayed in SAN HQ

  Hello

  Poster for the first time. We have just implemented an EqualLogic SAN, PS6100X network, and we're having performance issues between our DPM backup server, one of our hosts Hyper-V and VM images stored on the San. I will try to provide as much information as I can

  Environment:

  Dedicated iSCSI using Dell Force10 switches network

  hyper-V (Windows Server 2008 R2) 3 hosts
  -2 hosts has a NETWORK 4 port GB dedicated adapter connected to the iSCSI network; 1 host has connected to the network iSCSI NETWORK 2 GB dedicated ports card
  -Each Hyper-V host computer has a dedicated on the EQ SAN, RAID-50 volume that stores the Hyper-V virtual machines
  -EQ VSS provider installed on all hosts Hyper - V 3 and works correctly

  Using DPM 2010 for backup

  Problem: on Hyper-V hosts 1 and 2, any/all backup activities are very slow. On the Hyper-V host 3rd, however, activities related to backup all are incredibly fast! We compared the NIC configurations, HIT / settings ME and ASM, but we cannot understand why it is so slow on hosts 1 & 2.

  In addition, whenever DPM 2010 tells the EQ VSS provider to create a snapshot, we see the snapshot being created in the EQ Team Manager, but he does not appear in the list of iSCSI connections. According to the documentation SAN HQ, instant and volumes should appear here.

  We also disabled TcpAckFrequency for all 3 hyper-v hosts. It helped a little, but there is still a HUGE difference with regard to backups of the DPM.

  We're pretty sure that there is something misconfigured on the hosts Hyper - V 1 & 2, given that the host Hyper-V 3 has no performance issues.

  How can I get snapshots to appear in the list of iSCSI SAN HQ connections?

  Version information:
  SAN AC = 2.2.0.5924
  Storage Array Firmware = 5.2.4

  There are two different issues in this post for the SANHQ doesn't show only not iSCSI connections.

  Now SANHQ displays the correct total connection number but doesn't provide details of connections individual iSCSI for snapshots, which it should. So in the meantime use Workgroup Manager that shows the details for each snapshot (I know that's not the best answer, it's a short term solution).

  The fact the SANHQ shows details of instant connection does not mean that they aren't here and I can't imagine anything to do with the question of the DPM.

  The real difficulty, look for upcoming beta SANHQ and subscription for this on the EQL support site. You can do it now.

• Cannot change the settings after the take snapshot in VM

  Hello forum, I need to increase a disc size and the number of virtual processors on couple of virtual machines, the last week I have instant tool of these virtual machines. Today, when I try to change the settings, I see that the options are grayed out. Why is it so? This is a limitation of vmware. Do I have to delete the snapshots before making changes? Which will remove the ability to roll back changes if necessary. I'm under Windows 2008 R2 virtual machines.

  Virtual disks can only increase if they have no active snapshots. The snapshot files contains modified data blocks that correspond to their parent records, and this mapping I lost if you have increased a virtual disk with snapshots.

• Firefox opens the last session and tabs regardless of settings.

  For the last month or two, I had this problem as well as others. Kept getting a popup to set my search engine, I did several times without success. This question went. Tab question remains.

  No matter what setting I use open the previous session. I have Tab Mix Plus 0.4.1.8 so I've disabled that and checked the settings in FF to open to my Home Page. No good, don't always open the previous session.

  This was not a problem with Tab Mix Plus over the years that I used it. Exactly, I removed it from the Add - ons. Options of FF and together to start with the Home Page and restarted FF but always opens the previous session.

  Including a snapshot of the modules enabled.

  What is the cause?

  Olhank

  Your list of details of the system shows that you have a user.js file in the profile folder to initialize prefs each time you start Firefox.
  The user.js file will be present if you or a other software created this file and normally will not present.

  You can check if you have a user.js file in the Firefox profile folder that affects the pref browser.sessionstore.resume_session_once true value.

  • http://KB.mozillazine.org/browser.sessionstore.resume_session_once

  You can check its contents with a text editor (right click: 'Open with'; do not double-click).
  The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

  You can remove the user.js file if you do not create this file yourself.

  You can use this button to go to the current Firefox profile folder:

  • Help > troubleshooting information > profile directory: see file (Linux: open the directory;) Mac: View in the Finder)
  • http://KB.mozillazine.org/Profile_folder_-_Firefox

  Windows hides certain default file extensions.
  Among them .html and .txt, so you can see only a user file name without .ini and .js file extension.
  You can check the type of file (file extension) in the properties of the file via the context menu in Windows Explorer.

  Guys,

  I'm trying to customize a few things about Motion 5 and really I was wondering how to add these lines of text in the settings?

  Tried to google it, but without success.

  

  I think you need to learn how * write * FxPlug effects plugins. You cannot add these labels/buttons on the move as it is. What I usually do, is create a platform > pop up widget and use remove the "Snapshot" texts... "(and usually replace it with a series of quadratins (---) to create a line of separation.) To help you, you must have a 'sex' you can show/hide with opacity (and a rig box) which displays the help text.

  ·        The unit is able to reload Windows from this mode faster then CD.

  ·        The default password is 000000 (6 zeros) and it is shown when you are prompted for the password.

  ·        Users are able to change the password in this mode for eRecovery only.

  ·        The system can retrieve the hidden on the hard disk (partition PQService) image or a CD/DVD media.

  ·        It is possible to reload the factory CD/DVD style or snapshots that creates the eRecovery Windows version.

  2. in Windows, there are 3 ways to access eRecovery functionality.

  ·        When reinstalling from the CD/DVD's you will lose the eRecovery program but the DOS version can still function, as if uninstalled, you can not reinstall.

  ·        eRecovery uses Ghost (as well as the use of our recovery CD) to create snapshot images.

  ·        If the PQService partition is removed using fdisk or a utility under Windows, you may need to reinstall Windows.

  ·        If the system is recharged using the DOS version you retain the eRecovery feature

• Deliver the profile of the user - My Documents folder moved to C:\Documents and Settings\TEMP. I can't view or access this folder to copy My Documents back. Help?

  XP Home SP3 on my laptop (no not in network - independent).

  After an Adobe Reader 10 X installed, there is a reboot, and when I logged in the profile that appeared was not mine - it was as if it was a new installation. I looked for my personal documents under My Documents and did not find them. So, I looked for them on the C: drive, found (no not noted where), and copied My Documents to what seemed like the name /my Documents /. After that, I could access my documents by clicking Start-My Documents online. I did another reboot. Now, after login, my old profile is displayed, and the My Documents folder is empty except for the value by default my pictures, my music, my videos, and favorite - and these are all basically empty.

  I then ran a program Search and Recover to find my documents - they were found under C:\Documents and Settings\TEMP\. Unfortunately, I can't seem to see that to explore (I have it configured to display the hidden files and folders). Is it possible to go to this folder and the moving my Documents back to my profile?

  Thank you

  Hello

  You can view these methods:

  Method 1:

  Check to see if the problem exists in Safe Mode, if the computer works as expected in mode without failure, then we can solve the problem in the clean boot state.
  a. refer to the article below for the procedure safe mode in Windows XP
  A description of the options to start in Windows XP Mode
  http://support.Microsoft.com/kb/315222

  b. it is a possibility that there is a startup program that is launched with a command line and it appears.
  You need to perform a clean boot to find the program that is causing and then disable or remove.

  Note: When you are finished troubleshooting, follow the steps as explained in the article to reset the computer to start as usual.

  Method 2:

  System Restore takes a "snapshot" of critical system files and some program files and the registry settings and stores this information as restore points. If your computer is not working properly, you can use these points to return Windows XP to a previous state when your computer was working properly restore. It can also change scripts, batch files, and other types of executable files on your computer.

• size of the snapshot is taken from its volume?

  Hello

  I worked with Equallogic there are too many years, but not at HDS.

  If we take the snapshot of a volume, then the space will reduce its volume?

  Then, many times wherever I take separate instant the more space will be that she cut of its volume?

  Thanks in advance...

  When you take instant Compellent you freeze your volume. There is no copying of data process - now, each new entry data (e/s) from the server to the volme takes extra space (space is reserved). How much space does take to new entries in the frozen volume? It depends on the rate of change of volume...
