RAID levels for virtualization (Hyper-V)

Similar Questions

• Suggested for the RAID level configuration

  Hallo,

  I have a server 4core, 16 GB of RAM and 4 SAS 140 GB discks whith fiber channel EMC SAN. What is RAID level suggested for reduncancy and performance?

  RAID 1 + (a single disc advanced to other uses)

  RAID 10 (is really necessary for an ESX configuration?)

  others

  RAID 5 (suggested for VMFS, but not for a simple configuration, ESX)

  RAID 6 (not suggested because that too slow)

  Thank you

  As for local storage (as opposed to the EMC SAN) I'd go with RAID 1 + 0 for optimal performance. If you have an EMC SAN you probably store most of your VMs on the San. Your local storage space will be for your ESX installation and perhaps a data store for testing. Thus, you do not want to go with a RAID that offered high performance and redundancy, even if she does a high-cost disk, because the size is not you primarily on local storage.

  As for your EMC (Clariion AX regardless), you will want to cut LUN based on the needs of performance of your virtual machines.

  LUN RAID 5 for your regular VMS

  LUN RAID 1 + 0 for SQL (Oracle or Microsoft SQL SERVER) or machines virtual Exchange

  Just my two cents on the views of storage vary, and the right answer for you depends on your environment.

  Satellite A300 - 234 MODEL NO. PSAGCE. What RAID levels? 0 or 1? or 2,3,4,5?

  Hello

  As much as I know the laptop does not support (hardware) RAID
  You won't find anything in the BIOS.

  But a software raid was possible;
  For this you need a RAID tool.

• How to change mini H730P RAID level

  Hello

  I read H730P the user guide:

  

  Who mentions the possibility of change of a virtual disk's RAID level, and adding capacity of a virtual disk. However, there are no instructions on how to do it. I looked through all the menus can be found in the BIOS RAID config, I cannot find anything to do with the change of RAID level. I also watched menu iDRAC for storage options.

  Can someone point me in the right direction? Currently, I have two physical disks in SAS in a RAID1 and would add more than 3 drives to convert it to a RAID6 and increase capacity.

  Install OpenManage Server Administrator, go to storage, PERC, virtual disks and select Reconfigure in drop-down list of tasks available for your table.

• Help Setup RAID SATA for ESXi 4.1

  Hello

  It is the first time that you try to use vmware.  Any help is greatly appreciate!

  I just built a server around the Intel s5500hcvr mother. I have 6 SATA HDD I want to set up in a RAID. The integrated RAID controller seems to be very limited and does not seem to be supported by ESXi 4.1 (when I run ESXi 4.1 installation and it asks for a location for installation, all my discs are individually listed instead of virtual drives that I created with the RAID controller)

  My questions:

  (1) what is the suggested configuration of HDD (RAID levels / number of berries) for ESXi 4.1?  Can I create 1 RAID 10 array and set everything up to that?  or take one of my disks and install esxi 4.1 on it and then create a RAID with the rest of my discs and use it to store data?

  (2) anyone can provide links to some SATA RAID controllers that are known to work with ESXi 4.1 (and is the supposed to recognize virtual readers created by the RAID controller setup ESXi 4.1)

  Your motherboard has a RAID controller software which, as you have discovered, is completely not taken in charge by ESX/ESXi... You will need to get a RAID controller that is on the HCL for SAS and SATA hard drives (not one with battery backup write cache) so you can use any type of RAID configuration.

  My preference for Internal RAID configurations (on the host) are two drives mirrored for ESX/ESXi to reside (preferably being SAS 10 k or 15 k RPM, 73 GB or 146 GB in size) and then another table for the data store. You'll want to keep the data slot store table 2 TB-512 b size in order to present to ESX/ESXi as a LUN. Or you will need to get a RAID card this split of the support to the top of the table in the smaller of the virtual drives that can be presented for ESX/ESXi and LUNS.

  Search for controllers using the LSI MegaRAID chip as a good first lap. Some Adaptec cards should work, but I've seen people post questions on those recent (more recent than in the past). MANY manufacturers rebrand/efficiency the LSI MegaRAID Controllers server, such as the Dell PERC 6 series cards.

  For the use of 4 disks SATA, RAID 10 (on a BBWC, fully supported, controller) will give you the best performance. It will compare with SAS drives however. IF you do not plan on any virtual machine running with anything beyond light IOPS / s then you should be ok (or with very light loads)... If this is going to be a production server, then get the SAS drives all around.

• Tecra S3 - need SATA / RAID driver for installing Windows XP Home edition

  I'm doing a new installation of windows xp on a Toshiba Tecra S3 model PTS30E-0DT03FDU
  Who knows where to find the RAID driver to load when you start the installation of xp?

  This model no longer appears in the driver download section.

  Of course, it is listed by download, but the older models are listed in the ARCHIVES.

  Please visit the download page for Toshiba - http://eu.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp - once again and the slot type of product choose Archive.

  For Windows XP Home edition, you will find RAID driver for download.
  Can find you it?

• Satellite C870 - 1 H 2 and support for virtualization

  Hello

  I am (was to) buy a Toshiba Satellite C870 - 1 H 2 (from amazon.co.uk).
  The specifications look ideal for me, but at the last moment, I thought to check if VT - x extensions are supported.

  I know that the processor supports extensions (as detailed here: [http://ark.intel.com/products/71465/]), but I know also that the extensions are often not enabled (or there is no option in the BIOS to enable them).

  The expression "Virtualization Technology" (which is present on other pages of the specification) is clearly absent from the plug laptop here: [http://www.toshiba.co.uk/discontinued-products/satellite-c870-1h2/].
  I saw some comments that suggest the Satellite * Pro * series usually provides the support for virtualization, but it always seems to be missing on many current models of Pro's specifications.

  I don't know why the C870 would not support VT - x, when we know that his material, but the specifications indicate that this is the case. On the other hand, I found no references to people complaining about the lack of VT - x support.

  So my question is, the Satellite C870 - 1 H 2 actually does support VT - x, or not?
  (and if not, because it takes just a very small piece of code BIOS, why not?)

  Thank you

  > The same issue applies. These models are supported virtualization

  VT support is always depends on the CPU built in Notepad. But you mentioned it in the first post.
  According to the page of the Ark from Intel, the Intel Pentium 2020 M processor supports Intel Virtualization Technology (VT - x)

• Google maps do not appear right, the game is good, but about half of it is said ' we're sorry, but we have no maps at this zoom level for this region. " Zoom does not help.

  When you display a Google map, I get about four vertical bands which alternately display well and gray stripes. The gray area shows the message "we're sorry, but we have no maps at this zoom level for this region." Zoom does not get rid of the grey areas.

  I had this problem for over a year and work around it using MS Internet Explorer or Google Chrome which works Ok. Otherwise, Firefox works great and I use it for everything except Google Maps.

  I tried an uninstall of FireFox and then reinstall, but it did not help. I don't remember what I was doing when this problem is first presented.

• What is the level for Qosmio X 500 SATA - 10U?

  Hello

  I think to do a SSD to accelerate the time to start on my Qosmio X 500 - 10U.

  Anyone know the SATA level for this machine?
  How can I find out this information?

  I can't find any information in the manual or specification. If the motherboard is not enough fast then the SSD will not help much.

  > Anyone know the SATA level for this machine?

  That's easy, you can get details of material using a diagnostic of freeware software.

• RAID 0 for a RAID configuration not "this computer's hardware may not supported booting from this drive.

  I want to install a new HARD drive in a tower of the mine to a friend. It was initially created as a RAID 0 configuration with two 160 GB HDD. The replacement is a single 1 TB of HARD drive. I get the message "this computer's hardware may not supported booting to this disk.» Am I missing an approach from a RAID 0 for a RAID configuration, no?

  Hi RegularPencils,

  I suggest that you check in the basic input/output system (BIOS), if you find an option to disable the RAID. If you find, disable the RAID and try to install Windows vista, check if it helps.

  Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  Error message when you try to install Windows Vista on a computer that contains multiple RAW hard disks: "Windows cannot find a system volume that meets its criteria for installation.

• Foglight for virtualization 7.0 Standard Edition Compatiibility problems with vSphere 5.5

  Hello

  I couldn't understand how just after to the Foglight for virtualization forum, so I apologize for this post being in the wrong place.

  I have the Foglight 7.0 Standard edition and I'm unable to see virtual machines on the hosts of a new vCenter Instance I added to Foglight.

  I have enough licenses and the hosts appear in the inventory, but if you hover over one of the new hosts attribute 'State' reads "Not responding" and appear any of the virtual machines in the cluster.

  Any ideas as to what could go wrong or what I would have been able to hurt?

  Thanks in advance.

• HP Pavilion P6-2170 - support for virtualization?

  I bought a HP Pavilion P6-2170 today and wanted to turn to virtualization Hyper-V (I run Windows 8 Enterprise).

  The CPU would support it (Core i7), but I'm not sure about the motherboard (it's a 2AC2 of PEGATRON CORPORATION 2.00).  There is no option in the BIOS, so my question is this computer supports virtualization?

  Hello

  Should be safe in the BIOS as shown:
