• SAN starts a B200M2 with local disk

  I have a B200M2 with two local disks in it.  Currently, I'm SAN all my startup B200M2.  If I had a few drafts to the blade, but I didn't so I go in, I'd take the local drive.  Service profile, I configure to configure my blades has the boot order using a start-up strategy that starts from SAN.  It works without problem.  I also use a local disk Configuration strategy that has no local storage.  If this model of service profile will not work with the B200M2 that has a disk in it.  So, I cloned the templace of service profile and just change the policy Configuration of Local disk to any selected item.  Can I deploy the blade properly with this model of service profile, but I get an error of blade saying 1 Local disk on the operability of the server 1/1: inoperable and Local Disk 2 on the operability of the server 1/1: inoperable.

  How can I get rid of this error?  What am I not wrong which causes this error?

  Hello Russ,

  You have the operating system on this blade? UCSM version?

  If it is the 2.0.1 and OS is not running on this blade, the alert may be due to the following defects

• Weird disk problem

  Hi all

  I see a problem never seen before where I increased the size of the hard drive set up by 20 GB on a thin disk layout, then extended on the disk in the disk on my Standard W2k8 server management, however, the size of the disk in the Local disk properties is still only show 100 GB and disk management displays 120GB. I tried a reboot but saw no change. I left a few screenshots to better describe my problem.

  Any help would be appreciated. I've been a little slow this week so I really hope this isn't something very basic im hurt here haha.

  I've seen a few times so far, and there seems to be a problem with Windows do not update its partition information correctly. The best way to solve this problem is to increase slightly the virtual disk again, followed by resizing/increase the partition in the disk again Manager.

• Calculation of resources LM disk space

  I'll put up a configuration of demo with about 300 GB of 10 servers. I want more people to use at the same time. If I have 3 users connect to LM at the same time and they deploy this configuration in their work space, will it take 900 GB of space if users are deploying all their macines? Each configuration will take up to 300 GB? Or LM records changes? Is there a documentation on that? Thank you!

  3 x 300 GB machines will take up to 48 MB of space per copy initially and then grow in size as are written by blocks.  Its a statement of changes based on block by block, called "copy on write" (COW).

  More info below...

  Disks of COW

  COW disks are the disk layout behind REDO logs, instant, linked clones and almost every computer created by the Lab Manager virtual.  These are files that represent a full disk by referencing a basic disk instead of copy it.  The disc of COW begins as a file (16 MB) empty and captures all the entries in the instance it represents in a sparse format.  Read both the disc of COW and underlying basic disks, you get the equivalent of a new instance of disk.

  A multitude of disks of COW can refer to the same basic disk to create multiple copies of this disc. COW drives can also be built out of other disks of COW, so the eventual structure in laboratory Manager looks like a tree of disks, which the internal nodes are shared.

  Lab Manager limit the tree to a depth of 30, and there is no limit to the width of the tree. Lab Manager also ensures that all internal nodes are read-only at the application level, and that leaves nodes are the only nodes in the tree that can be "run" so that we do not destroy the dependent disks of COW. As VMs are removed in the application, a background process asynchrously Lab Manager deletes nodes in the tree he can without affecting dependent disks of COW.

  When the disks of COW are used, their data structures pick up of ESX (the "pile of COW") kernel memory. The pile of COW is 40 MB in ESX 3.0 and up to 192 MB on ESX 3.5 u4.  Most of the COW lot is taken over by "inputs of root" which use 4 bytes from the heap of COW for each 2MB of disk, represented by disks of COW.  The result is that we can only open disks of COW representing a sum of 20 TB (40 MB / 4 b * 2 MB) of the base on each ESX Server disk.  This includes all nodes of a chain of disks of COW, so if you deploy virtual machines, with a string of 10 deep drives built COW out of 250 GB basic disks, you can open only 8 of these virtual machines before you run out of heap of COW.

  Performance of the disks of COW

  The impact on the performance of the disks of COW is complex, with hits of peformance and potential gains.  There will be a small performance hit start during the caching of metadata, degradation of performance during certain i/o operations and potential performance gains to the storage array cache.

  Metadata cached in memory to start the virtual machine describes the sparse structure of the COW drive - which hit to get the data from the file. Given that these metadata can become quite large, caching only a part of it.  When a virtual machine is a virtual SCSI read and we reached the metadata cache, each virtual reading will result in a single physical reading.  If we have a lack of cache, however, we first must make a metadata read before making the actual data read. Therefore, we can do more than a physical read by virtual reading if a virtual machine is reading from a variety of sectors of the disk.

  Another potential impact on the performance of the disks of COW is blocking during writing SCSI. Rare disks of COW will develop as the data is written to the disk (in segments of 16 MB), and files should be locked as they are grown.  This does not work with ESX virtual machines with a monolithic basic disk. The impact will be more apparent during continuous written causing the COW drives to grow rapidly.  In practice this was not a major issue in the facilities of Lab Manager.

  There are potential performance benefits to using disks of COW because of the caching of the storage array. Storage arrays cache files commonly used in memory, and when you use disks of COW, and commonly used and to share COW records can be read from memory and no disk.  Director of the laboratory is a use case that can take much of this advantage.

  Maintenance of records of COW

  Basic direction is to not worry the length of chain linked clone until it is close to the limit of the System Lab Manager of 30. Directors must ensure that they keep enough available disk space on their berries to consolidate records when they get close to this limit.

  Borderline cases

  There are cases where the length of chain linked clone must be controlled:

  Large capacity disks base & long strings: each ESX 3.5 u4 server can support only disks of COW representing 96 TB of disk Basic.  If your basic disks are large (100s of Go), you can control the length of chain drive of COW to stay away from this limit.  Lab Manager understands the limits of COW ESX and act appropriately limits are reached.

  Wholesale writes: for use cases that make large writes to disk (loads of large databases, application installs, etc.), the advantage of related clones Compact is reduced to the minimum. In these cases the previous consolidation can save a considerable amount of disk space. If you can design processes such as major Scriptures are made once and everybody down copies of the result, you will save a lot of disk space.

• Cannot install anything but XP after memory upgrade

  My friend had a hp630 running Windows 7 Home Basic, 32-bit. He went to a flea market of computers where they replaced the system memory with two new modules of 4 GB. The system running my end but apparently could not use more than 3 GB of memory by showing that 8 GB has been installed, he wanted a 64-bit system. Given that the system had been there for a few years and accumulated a lot of garbage, we have decided to do a clean install. So we deleted and recreated partition D: with Minitool Partition Wizard and tried to boot from an installation DVD. And here's the problem: no matter how much we have tried different versions of Windows, the only one that worked was XP with AHCI drivers embedded in the disc according to instructions on this forum ( http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/SATA-drivers-for-XP-solution-on... ). both XP sp2 and sp3 XP worked fine. However, Win 7 32 bit, Win 7 64 bit, Win 8 32-bit, win 8 64 bit everything has failed in a similar way: they would go by loading files (Win 7 shows a progress bar while Win 8 showed a logo) and then to reboot (Win 7 without warning, win 8 after a brief demonstration of an error with a sad smiley).

  So the question is, how I approach this problem? Upgrade memory to do the system incompatible with Win 7/8? Unfortunately, the original memory module has disappeared, so I can't go back to the original hardware configuration. Should I try XP 64 bit? I heard that this is not the best system to 64-bit, due to compatibility problems (some have been resolved in later versions). I may try it anyway out of curiosity, but in the meantime would appreciate advice.

  Thanks for the quick response!  The machine has Core i3 - 370 M, which certainly is 64-bit capable. Windows ISOs, both legal illegal, don't miss, and device startup doesn't seem to be a problem, either: the computer accepts the DVD I did very well and copied the files from there, but then something went wrong.

  I did the format of the disk as the partition will, but I have not done anything with other partitions. Is - this possibe that Win 7/8 did not like fantasy HP partitioning? There are about 10 GB or partition so hidden, then 2 GB C: drive containing HP tools, then D: to E: and system for data. E: we did oursevles during initial installation for a long time it has so changed their size using MiniTool Partition Wizard. Windows XP has no problem with this disk layout, but perhaps the 7/8 behaves differently?

  Another thing I noted is that F11 at startup has no effect. Is it normal for a model that was sold without any Windows? Or is it possible that it reflects somehow the problem I have with installing Windows?  The absence of function F11 is because you have made changes to the recovery D: partition. Any changes made to the partition will delete the F11 recovery capacity.

  You will find that you have more success if you delete all partitions, then proceed with the installation.

  Let the Windows 8 or 7 Installer create and format partitions of its own during the installation procedure. Normally the C: partition is the system partition,

  I propose the first because you do a clean install instead of use the recovery disks created by the HP recovery media creator utility. Using the recovery media, scripts to create all the required partitions independently and install most drivers as well.

• PowerVault MD1000 Perc 6/E hot swap

  Which would prevent me from doing a Hot Swap on a 136GB 15K SAS drive on a PowerVault MD1000 with a Controller PERC 6/E for Adaptive Read Ahead, write new policy, broadband strategy of disk, RAID-10 in degraded state, a defective disk cache 64 KB, disabled?

  Blew up a car and you want to make sure I can hot swap on this machine. I read through product docs, but you are looking for something extra that I want to check that I missed on. Server of our warranty and support from last year. Everything I see is green lighted to go, but I always want to get will as many resources as possible before blowing a RAID 10 potentially because a controller had some setting that prevents a switchable good hot to rebuild. Make backups before swap, swap during off-peak hours doing rebuild starts on commercial operations.

  Hello matt.newman,

  For the MD1000, you can replace a failed during execution of the MD1000 drive.  When you insert the replacement drive, it will start a reconstruction.

  To replace the Perc6 you will need to do is the following:

  1. Make sure you have a good backup tested all the MD data
  2. Turn off the server and the MD
  3. The PERC6. Remove and replace
  4. Turn on the MD & wait that he move to a ready state
  5. Turn the server & go in the new Bios Perc6 / configuration
  6. You have to re-create the raid10 & together for Adaptive Read Ahead, political writing back, broadband 64 KB, off the disk cache strategy
  7. Once you have created the raid then leave the PERC6 configuration utility and the Server post to the operating system
  8. Once logged on the operating system you can then run the restore to restore your data to the MD

  Please let us know if you have any other questions.

• HO to start from a SD card with B200 M3 with 2.1 - 3A

  Hi all

  can someone help me?

  I need to start my B200 M3 of my Flex SD Card 16 GB of Cisco

  I made the following adjustments

  -Servers\Policies\root\local Disc political Config--> Flex Flash State = Enable + Mode = No. Local storage or any Configuration (two doesent work)

  -Servers\Policies\root\Boot Policy\ 1) CD Rom (doesent work)

  (- Servers\Policies\root\Boot Policy\) 1 CD Rom 2) floppy (doesent work)

  I can boot the ESX ISO but I don't se any of installation disk. The SD card is in the lower slot

  Can U help me?

  PS: the system a 2.13 hole has

  Hello Stefan,

  First of all, you have activated support SD card in local disk configuration strategy?

  If so, is the part of the policy of the service profile?

  Once you associate the service profile, enter the BIOS and make changes to the boot order of the devices.

  -on top of the doc.

  When FlexFlash is enabled in a policy of local disk and a server is capable of supporting SD cards, the controller of FlexFlash will be activated during the deployment of service profile.

  To manually start since the partition of the HV, Local disk should be present in the startup strategy used in the Service profile and be launched from the start of the BIOS (F6) menu.

  Limitation

  If FlexFlash is enabled and the startup strategy contains the Local disk, boot SAN or iSCSI Boot, then the boot order can be determined. You should disable FlexFlash before using one of these startup options and enable once startup is complete.

• Second hard drive problems

  I have a Dell Precision 380 and that you just added a second hard drive, a SATA 750 GB WD. I use Windows XP pro.

  I have problems with this drive. When I start the machine it takes forever to get to the login screen. After I got the new drive connection is not visible in Windows Explorer. If I restart the machine, so it loads quickly and everything is OK. Then everything is OK either re-booting or switch to standby mode.

  However, if I closed and leave it for a long period of time (at night) and re - start the problem above apperas yet and I have to wait as the login screen and restart.

  If I go to sleep mode during the night and then 'wake up the machine' the next day morning I get several disk writeback:------$fMt error messages. I have to reboot the machine for everyone to be OK.

  I have formatted/re-formatted and partitioned the drive several times (NTFS) partition/disk layout is OK.

  I start to think that maybe the BIOS does not like Western Digital drives.

  Any information appreciated.

  Thank you

• Why do I get this jerky playback?

  Long time reader, first time poster, I'll do it is short and sweet. Here are my specs:

  27 "IMac

  Intel Core i7 3.4 GHz

  24 GB 1600 MHz DDR3

  NVIDIA GeForce GTX 680MX 2048 MB

  SSD 1 TB internal drive of Fusion

  
  

  I work in a fairly large (images of 1 TB) 4 k mixed with 2 k project. It is a 3 simultaneous shoot camera, so I need multi-cam. I have two that WD Caviar Black 7200 RPM external drives. I also have a Lacie 1 TB disk Thunderbolt.

  Because the end result will be 1080 but maybe 2 k in the future, I decided to import all the RED images in native mode (as opposed to the transcoding to prores 1080 format). All my clips are 1920 x 1080, with multi-cam nesting in 1080 as well. RAM is assigned to first, other 4 GB 20 GB.

  No matter what I tried, I still get jerky in the project... reading especially with multi-cam enabled, even in the setting of my resolution of 1/4. What I tried:

  All media on the drive WD 01... Project, Cache, Preview, Scatch disk WD 02... Internal SSD for the OS and applications: Terrible performance

  All media divided into WD 01 and 02 WD... Cache, the OS and applications on the internal SSD flash drive... project, preview, scratch on WD 01. I also tried the same thing but with the draft, preview and scratches on my Lacie 1 TB Thunderbolt and internal SSD: a little better than all media 01-disk.

  At this point, I feel like I tried every variation from will the MEDIA, Cache, project files and Scratch/preview but nothing seems to give me a fluid reading constantly. I'm going to brief periods where it is very smooth, but choppy and then shortly after. I would understand if I try to edit in 2 k or 4 k, but all my calendars and the nests are 1080. Even if I have pre-made sequence, it barely helps. Is it possible that I need more RAM, a better card GFX, better external hard drives? Help?

  First EDIT: Updated to the latest version of 2014. No major applications running outside the first. All my drives have at least or near 50% space available.

  Recommend that take a look for implementing disk layout & such on the Page of the Tweaker...

  Page of Tweaker...

  http://ppbm7.com/index.php/tweakers-page

  Basically, they recommend only the file on the system/OS disk... and then put things on other readers by the needs of the 'good'... some must quickly connects, an only couple of fast connections for most.

  Images is essentially a one-way operation unalterable and export out is essentially a read operation, so those can be necessary on somewhat slower connections as long as they are not on the SAME drive on a slow connection. Such as tell the PNY 128 GB high speed USB3 flash-drives to an external port USG3.0 on your computer. I adapted it from the other users, and this works well enough for my 1080 p images. I export to one of the several disks, that i've got in external boxes connected by USB. It is sufficient, but not flamboyant.

  Everything else... files, database, previews, cache... There is a TON of work in reading/writing courses constantly while playing with these project. Drives up to 7200 rpm or faster 'standards' or SSD, connected internally through SATA-II or better, or external via eSATA II and Thunderbolt connections are necessary. Close read/write speeds supported appropriate for work in the massive tests they did what above, none of the available Firewire or USB2/3 connections mentioned site. The speeds of "burst" claimed by the manufacturers are performed on absolute most ideal landscaping with UMM... size right? ... of data packets to get the best numbers. They are not the usable numbers for requests to read/write strong and constant as the Adobe DVA through the machine.

  Don't forget... during playback... PrPro "reads" the source footage including when to jump in & on each clip, throw in all your instructions for Assembly, color changes, transistions, effects, EVERYTHING... and on-the-fly built the image you see on the playback screen. It does not have something so he can just 'read' the disc, does it on the fly. Even when you glimpses of a section of a timeline, any change you do... these glimpses are exceeded.

  That's why we all need machines that both have a material quite solid on the mobo, AND a lot of high speed drive connections. Best is tell a table of 4/5 disc drives of 2 TB in RAID 0 or 5 for the cache of d-base, files, projects, & previews... and who may even have media (original film) on it.

• Expand the C partition in Windows Server (not not using diskpart)

  Hi Experts,

  I have an of Windows 2003 virtual machine that has a 12 GB C drive only. I need to decompress. I know that we can use diskpart to extend the drive, but the problem is here that the hard disk is divided into two partitions (C and D), because of which even if I increase the size under the ESX, I don't then expand in Windows using diskpart as it is said there are two partitions on the same disk. Someone help me!

  Volume 1 is the selected volume.

  DISKPART & gt; extend

  The volume you have selected may not be extended.

  Please select another volume and try again.

  Hello!

  Normally, you will only be able to extend the partition that has free space immediately after it on the drive (and this is where the free space is added when you expand the virtual disk). So, if your disk layout is like this:

  DISC

  (block0 |) Partition1... | Partition2... | Free space.........................................| last block)

  you will only be able to extend Partition2

  This is why it is recommended to create a partition per virtual disk.

  In your case, I'd watch if it is possible to:

  (1) add another virtual disk to the virtual computer and create a partition (say f :)

  (2) move the data from the disk D: (Partition2) the newly created disk (if the existing D: holds a swap file, you need to create a swap file on the new drive, and then delete D: pagefile in computer properties > Advanced tab > performance settings > Advanced tab)

  (3) change the drive letters in the Disk Manager (change the drive letter to D: in a free r: one, for example, then change to your new drive d :) drive letter)

  (4) possibly restart the virtual machine to see if all the services are running as expected

  (5) use of the Disk Manager to delete the Partition2 (after this your vdisk that holds Partition1 should have lots of free space immediately after Partition1 and it is expandable)

  (6) use diskpart, extpart or any other utility to develop the Partition1

  (7) avoid creating multiple partitions on virtual disks in the future

  I hope this helps.

• Shared storage on a Windows Volume Format

  Hello, I'm looking for some help on my lab at home. I have 2 ESX hosts and iSCSI cake just to install on a Windows 2003 server that points to its own partition 40 GB IDE. My guests see the iSCSI target without problem, but when I'm working through the add storage Wizard, I get the message, "Unable to read the disk partition information" to the current disk layout screen. I guess it's because the drive is formatted with NTFS on a windows 2003 server. I'm looking for an easy solution that this iSCSI target will be recognized as a place of storage shared by my hosts. I think it needs to be formatted properly, but I don't know what to do. Also, I realize that this isn't a good solution, but I want to test it.

  Any help would be appreciated. Thank you.

• video copied to DVD does not match project that I can see

  Good,

  No doubt another basic question, but I can't find an answer in the Adobe manual. I just discovered (after burning 8 copies of the same file) that the film on the DVD does not match what I see on the screen of project. The drop-down list to organize > project resembles what I want except that he seems to have the original avi file that I edited later as well as the changed file. The timeline seems correct. The timeline seems correct. I tried to eliminate the 'markers', but there was none to remove - the drop down menu gave me the ability to add markers. A Council, is that the DVD is picking up a model of menu that I played with, but could not get to work and then deleted. I ended up using the title screen very basic with black video in the high title of range drop-down list menu rather than the option model to change. I see the new title in the scene and timelines. Yet once the previous question just posted, I don't see anything in the screen clip
  (e.g., boxes of th) under 'organize '. In addition, the video clip on the DVD appears truncated by about half of playing time.

  At one point I have only the old menu design clip shows just below the montor screen could display but could not know how to remove.

  Yes, I want to.

  Are you referring to the design of physical database (implemented disk layout, the locations of files etc.) or logical database design (schema, table structures, index, etc.)?

  Based on your requirement, the answer will change.

  But in simple terms, it would be better if you could take a course in local universities or colleges that have database THE program design. It is not possible to summarize the design of database in a few lines.

• Default VSAN (TTF = 1) storage strategy: large disks get stripped?

  What I discovered while ivestigating a resynchronization VSAN problems, is that two virtual machines have vdisks that are divided into multiple objects.

  It's strange because the default storage policy only sets FTT = 1.

  It is strange that there are RAID1, RAID0, RAID1 with the default policy objects, as seen in the attached screenshot.

  I guess that is somehow linked to the size of the vdisks. I also checked that wihth another installation of VSANS, it sound the same.

  Can someone tell me what size VSAN decides to scratch vdisk objects?
