• Cluster Hyper-V CSV allocation unit size

  Hello. Is there any recommendation Dell when it comes to the size of the allocation unit of the NTFS volumes that serve as CSVs (Cluster shared Volumes) in a Hyper-V cluster?

  Using EQL LUN in the background apparently.

  Where should we go with the default using Windows (based on the size of the volume/LUN) or should I use something different to optimize performance, for example 64 k?

  CSV store virtual machines with different workloads, nothing specific, such as SQL pure or web servers, etc..

  Thanks in advance.

  Hello

  Cluster size when you format a volume must always be 64K.   Which corresponds to the size on the spreadsheet.  Writing in complete stripes is the most effective way, it reduces the overhead of RAID.

• What is FAT, FAT32 & NTFS maximum file size of file systems supported? File system of all the methods of the passage of FAT & FAT32 to NTFS without formatting is appreciated.

  What is FAT, FAT32 & NTFS maximum file size of file systems supported? File system of all the methods of the passage of FAT & FAT32 to NTFS without formatting is appreciated. (IE without deleting the files from a particular disk).

  Difference between material FAT & FAT32?

  I have a disk full of files, and it is in the FAT32 file system. As I can't copy large files (5 GB +) in this player, I intend to fix this by changing the file systems. Apparently, it is not possible to do it without formatting. I am curious about a way to do this without destroying the drive.

  Thanks in advance.

  Difference between material FAT & FAT32?

  First, note that there are three varieties of FAT: FAT12, FAT16, and
  FAT32. Many people call just FAT16 FAT, because before that FAT32 is out.
  FAT16 is the only variety used for hard drives, so just
  The FAT was not enough.

  FAT12 (hardly any more used) had a maximum volume size of 12 MB.
  It has been used almost exclusively for floppy disks.

  FAT16 was used on hard disks (or partitions) up to 4 GB and had a
  cluster size which varied from 2 KB to 64 KB, depending on the size of
  the partition. It serves almost never again, because almost nobody does
  a as small as 4 GB partitions.

  FAT32 FAT16 succeeded and has a maximum drive size of 2 TB. His
  maximum file size is 4 GB, which explains why you can't copy a file of 5 GB to
  it. its cluster size is 4 KB up to an 8 GB partition. Beyond 8 GB the
  cluster size develops up to 32 KB.
  NTFS, that's what almost everyone should use on their hard drives
  today. Its maximum volume size is 2 ^ ^ 64-1 and its maximum file size
  16 × 1024 is ^ ^ 6 bytes (much more than the bigger hard drive available
  today). Cluster size is 4 KB, regardless of the size of the volume.

  I have a disk full of files, and it is in the FAT32 file system. As I can't copy large files (5 GB +) in this player, I intend to fix this by changing the file systems.

  Good! You should.

  Apparently, it is not possible to do it without formatting.

  It's not correct. To convert to NTFS, use you the CONVERT
  command. But first read http://www.aumha.org/a/ntfscvt.htm , because
  There is an important question about the size of cluster that is not obvious.

  Also note that conversion is an important step, touching everything on your
  drive. When you take a big step, no matter how unlikely it is
  always possible that something can go wrong. For this reason, there
  careful to make sure that you have a backup of everything you can not afford to
  lose before you start.

• Unable to find the required details for SNS-UCS-TPM in the datasheet as rack unit size

  Hello

  I'm just trying to understand the dimensions of the SNS-UCS-TPM device and the same power requirement...

  Is - this 1 U device with 1 x 650W PSU? I think details power but I'm not able to get the size details with respect to the width, length, and width.

  Can you please share the good link that will offer all of this in detail?

  The Trusted Platform Module (TPM) is a module of small integrated circuits on the new network of Secure Server (SNS) 3415 and 3495 device models. They are based on the platform Unified Computing System (UCS) C220 M3.

  Both the 3415 and 3495 have the same physical dimensions, differing only by the number of processors, memory and hard drives installed in their breast.

  The detailed characteristics of the UCS C220 M3 are here. You can see a diagram of where the TPM is installed here.

• MWI allocation unit

  Need help on the search for ports to be used only for MWI documentation that explains the percentage of voicemail.

  I read somewhere that 25% of the total ports should be assigned to MWI.

  I have about 1300 users/72 voicemail ports. All are defined for the processing of appeals incoming and MWI notification. Errors in the event log that shows the collisions between entering and MWI.

  Thanks in advance

  Hi Allan,

  Here is the reference you are looking for:

  Answering calls

  Check this box to designate the port to respond to calls. These calls can be incoming calls unknown callers or subscribers. As a general rule, the value answering calls on about 75 percent of the ports.

  Message notification

  Check this box to designate the port to notify subscribers of messages. Assign a Notification Message to the less busy ports, which are typically those with the largest number of ports for the phone system. Generally speaking, the value Message Notification Dialout MWI and TRAP connection on about 25 percent of the ports.

  Dialout MWI

  (not used by series or integrations SMDI)

  Check this box to designate the port to turn MWIs. Assign Dialout MWI to less busy ports, which are typically those with the largest number of ports for the phone system. Generally speaking, the value Message Notification Dialout MWI and TRAP connection on about 25 percent of the ports.

• What is the unit allocation size that is displayed in the window to format USB?

  Original title: allocation unit size

  What is the unit allocation size that is displayed in the window to format usb

  Hi Moaz,

  Thanks for posting your question in the Microsoft Community.

  I understand that you want to know the unit allocation size that is displayed in the format USB window. Correct me if I'm wrong.

  I will certainly help the question of fixing.

  In computer file systems, a cluster is the unit of allocation of disk space for files and directories. To reduce the load of the management of data on disk structures, the file system allocates no individual disk sectors, but contiguous groups of sectors, called clusters.

  On a disk that uses 512-byte sectors, a 512-byte cluster contains one sector, whereas a 4-Kibibyte (KiB) contains eight sectors.

  Refer to the below mentioned article and see if it provides information that you are looking for.

  By default for NTFS cluster size, FAT and exFAT:

• The unit of Allocation ASM vs Tablespace uniform extended

  Hi all
  
  I do proof of concept on the migration of our file system based in ASM and RAC databases. The current database has tablespaces with a uniform management of measure of sizes of measure 10 M, 100 M and 512 M.
  
  ASM, I see Oracle documentation that allocates the ASM extended based on the AU from 1 MB. After the sunset of the 20,000 first to what extent, the size of the measure becomes 8 * for then 20000 sets of measure. The increment for a measure of ASM is 64 * AU.
  [http://download.oracle.com/docs/cd/B28359_01/server.111/b31107/asmcon.htm#BABCGDBF]
  
  So my question is that how can I have some tablespaces with uniform measurement volume of say 100 M on ASM? If so, will be a more detailed breakdown ASM sizes measure to its default size of AU?
  
  Appreciate the answers on this one!
  
  Kind regards
  Naren

  Hello
  Please don't mix as oracle with the concepts of data scopes used here, see http://download.oracle.com/docs/cd/B28359_01/server.111/b31107/ostmg_gloss.htm#BABFCABI

  I guess you know about the concepts of the tablespace extents (you can have one size car or also different size). Here are the intra-space management tablespace. For extensions of data described here, you can compare it with BONE block in normal filesystem, and each award using the ASM consists of one or more data extensions (not extensions of tablespace).

  So my question is that how can I have some tablespaces with uniform measurement volume of say 100 M on ASM? If so, will be a more detailed breakdown ASM sizes measure to its default size of AU?

  IKE just as you can use the same size of extents for tablespace of 100 MB on a filesystem regular of the BONE 512 bytes block or 2 k or 4 k (or other). In this case, your database will want to write to allocate an extent of 100 MB and then ASM will take over the responsibility than the way in which it will physically store this measure 100 MB on disk group by spreading the Allocation unit. If your this measure when this group of disks, 100 MB is required to be distributed among a number of (set of data extensions) measure 20001 and your ASM allocation unit size is 1 MB, it will allocate extent file ASM 8 * 1 size and total about 13 degrees (13 * 8 = 104 MB) so that your measure of tablespace 100 MB can be stored.

• size of hard drive 2nd dv7-6b51ea

  Hello

  I have a dv7-6b51ea, the British model. Its original 1 TB drive started clicking... then finish. I replaced the main drive with a 250 GB SSD drive and reinstalled win7 64 bit. This works very well and is very quick to start and run.

  Having been in the back, I noticed a 2 slot of the drive Bay, I bought a 1 TB of seagate hybrid drive for this niche and have installed with cable.

  The first time I start windows, he saw the car and says that the new hardware is ready to use.

  Unfortunately windows cannot see the drive.

  I reinstalled all the current drivers on the support site HP and flashed the bios to the windows application.

  Can you shed any light on this please?

  Thank you in advance.

  Hi Wayne,

  You will need to just format the new HARD drive - try the following.

  Hold down the Windows key and press R.  In the run box, type compmgmt.msc , and then press ENTER.  Click disk management in the left pane and let readers load upward.  Right-click on your new HARD drive and select Format to start the wizard.  Windows 7 will affect a Volume label so if your happy with it, just leave the default.  File system is NTFS.  Allocation unit size must be left by default.  Select the option to perform a quick format if it is not already done.  Leave all the other default settings, and then click Ok, and then Ok to start the process.

  Once this done, your new HARD disk should now appear when you look under the computer.

• I have a 16 GB USB Firebird and the size on disk is only 14.9 GB

  Hi all

  When I format my usb drive, all I can get is 14.9 GB. Is this normal?

  and one more thing. I tried to format it like a chrome OS boot disk and made a big mess. Finally I managed to return to a single partition. This thing with the chrome operating system changed the default settings of the drive so I want to know what is the default allocation unit size (when formatting)? I think it's 4 096 bytes before I ate with it, now its default 8192. I don't know what was the default allocation size, so I need a number for an answer.

  Thank you very much!

• RAID block size and Lightroom

  I setup Raid 1 (mirrored) on two drives of 1 TB and in the choice of block size, this issue was raised. What size of block is best when using raid drives for Lightroom catalogs and dng, jpg and tiff files associated with each catlg? Currently, I selected 128 k because 90 percent of the cases are from 1 to 20 mb in size with a 6-9 mb avg. There are a few files to 20 k - 500 k.   Any suggestions or ideas? I'm on the right track for the use of space and a good performance? I do not seek for its remarkable performance space is use is my main concern.
  Steve

  Size of allocation RAID will affect the use of the space.  Use of the space is determined by the size of allocation unit file system.  For a file system that is for the most part, image, size files important allocation (64 +) is a good thing.

  Distribution RAID size must be at least the file system allocation unit size.  128K is a reasonable size for images for the performance.

  Keep it defragmented.

• Remove the recovery drive and drive C on the internal drive of 2 2nd

  I installed a Kingston 120 GB SVP200S37A / 120G on my HP Pavilion dv7t-1000 CTO Entertainment Notebook PC with Windows 7 Professional.

  I took the cable USB and case provided with my package and plugged my old hard drive of 320 GB.

  Installed the SSDNow v + Series software and installed it.  At this point, I was happy to see my new Kingston 120 GB SSD and unplugged my old hard drive.

  Last week, I installed my old hard drive to 320 GB in my laptop.

  My current SSD is the C drive and disc HP_Recovery (D).

  My old drive is Local Disk F and Local Disk G.  Can I do this in a single drive?

  Is it possible for me to remove the HP_Recovery (D) drive then put it on to my second drive?

  Hello

  Unfortunately, the second Bay of your laptop drive isn't bootable - this is true for all of the dv7 series, so spend the recovery Partition of your SSD HARD disk will cause any recovery attempt fails.  If you want to use a player of the second span, it can only be used for extra storage.

  To make the drive in the second span in a single volume, you must do the following - keep in mind that this will destroy all data on the disk.

  Hold down the Windows key and press R.  In the run box, type compmgmt.msc , and then press ENTER.  Click disk management in the left pane and let readers load upward.

  For all volumes shown on the Second disk, right-click each in turn and select "delete the Volume.  When you are finished, you should have just "unallocated space indicated.  Click on this and select Format to start the wizard.  Windows 7 will affect a Volume label so if your happy with it, just leave the default.  File system is NTFS.  Allocation unit size must be left by default.  Select the option to perform a quick format if it is not already done.  Leave all the other default settings, and then click Ok, and then Ok to start the process.

  Once this done, your disk should now appear as a single volume when you look under the computer.

• What to do after I wipe an external hard drive?

  I just used KillDisk to erase a 1 TB external hard drive. I still want to use this hard drive but my computer does not recognize it. I read that I might have to reformat or something? Also read something about Fdisk. Don't know if this is the case for me, no one knows anything about what I should do next? And how to do it? Thank you.

  This is the site with instructions. Unfortunately, I'm not very aware when it comes to technology. Help, please!

  http://www.killdisk.com/KillDisk-FAQ.htm

  Press start, search diskmgmt.msc, open that appears in the search. (should be "diskmgmt")

  Find your external drive, which, on the lower part of the screen, should have a giant bar with black on top of it. If it is blue, read the paragraph after it and ignore the following sentence. Right click after making sure is your external drive (you can tell by looking at how big it is), and then select new simple volume.

  If the bar is blue, and you are sure it is your external drive, it has already been formatted. In this case, right click, select change drive letter and paths, and if there is no letter listed, click Add, choose a letter and press Ok. It should be shown in my computer.

  If it's black, continue reading below.

  Press next, and then it will ask you what size you want the partition, and it should already have filled the maximum space, you can do. Press next. You can then select a drive letter, that will most likely be E, of course you can change it to any desired letter.

  In the next screen, it should have already chosen "format this volume with the following settings. Make sure he put the NTFS file system, allocation unit size must be default which is very good, and you can choose a name for the drive.

  Quick format is selected automatically and I would say leaving just checked, as a normal on a 1 format to player would take a few hours.

  Pressing should then start formatting. On this bar where you initially right click to start this, admittedly, formatting. When he's ready, he'll say: formatting (0%) and then it should finish quickly, because you have chosen to do a quick format.

  After that, the drive appears in my computer and can be used.
