• Multiple RAID - drive political Local configurations

  Hi guys,.

  We are made a bare metal installation and goes to 2x300GB RAID1 and 2x300GB RAID1 and RAID5 3x600GB.

  When I look in the local policy of Config disc I have to choose the RAID level, but how do you decide who's going to record hard with that RAID?

  Thanks in advance!

  Hello

  As far as I know, you don't have a multiple RAID array configuration option / levels with local disk at UCSM policy, you must restart the server, press the required key combination (Ctrl + H to PCIe adapters, but it is usually displayed at the POST) to get GUI RAID controller services and configure it from there.

  Check: http://www.cisco.com/c/en/us/products/collateral/servers-unified-computi... and look for "changing the RAID with the WebBIOS utility level" that will tell you how to do this...

  Let me know if you have any questions; If not, mark the thread as answered please

• General questions NAS, multiple drives, RAID storage

  I have a Linksys EA6350 at home that is currently configured with a passport of aging WD for networked storage. It is time for replacement and I'd rather use the current and the replacement of the disks simultaneously on the network.  My first question is if Linksys firmeware accepts disks placed on a USB splitter. If possible, I am also curious to know if the firmware can manage several partitions on a disk.

  If one or both are possible, so I wonder if I can set up a RAID 1 mirror without hardware RAID configuration. I know that it's possible on a desktop computer, but the general consensus among the computer saavy, it's that it would not fine performer. However, I'm not very concerned about time to read/write for what I want to store in RAID; I care to ensure that the data is never lost.

  In my head, I'm thinking the installation program looks like this:

  Dispatcher USB-> Disk 1-> partition RAID 500 GB
  |                        |
  V                      V
  Disc 2 500 GB partition mirroring disk 2
  (500 GB)

  Thanks in advance for your time and advice,

  Thanks for sharing. Our routers Linksys does not support RAID. You can consider a NAS that supports RAID, unfortunately, we do not have a type of House and consumption.

  Hello

  Did you create the external HP recovery media before you change your PC? If this isn't the case, then order the HP recovery media.

  Since you're already start your PC via an SSD, so you won't have to see that a large part of an increase in performance while SATA III is faster than SATA II.  Ports 0 and 1 are the only SATA III ports on the motherboard.

  Your PC boot in AHCI SATA mode with secure boot and off quick start?  I suggest that you download and install the latest version of the Intel IRST software from the Intel site.  Install the TSRI and reboot to make sure you're good to go.

  The following method via MSCONFIG will define the operating system to start in safe mode, which will allow Windows to load the appropriate drivers without modifying the registry. It worked for me on many motherboards with Windows.

  

  Now boot into the BIOS and change SATA RAID mode, disable the secure boot and quick start and maintain.  You PC start in safe mode?  If so, then go back into MSCONFIG and uncheck safe mode, save and reboot. You should be running in RAID mode. Now go to the OPROM Intel Control panel interface to create RAID 0 array.  You will have to wait a little Intel service is fully operational and it loads deferred.  At this point, turn off and unplug the HD and the SSD with the BONES, as well as the HP boot recovery media and see if you can load the RAID 0 array. You don't want the UEFI partitions to appear the other HD or SSD containing the operating system or eventually you multiple loaders to boot windows which lead to confusion.

• 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.

  You can't develop multiple VD through a disk group. You must remove the second VFD to reconfigure. You might be able to create a new VD with space, but you cannot expand existing ones.

• EqualLogic configuration and restrictions of RAID

  We realize that there is NO way we can remove the existing RAID array so that we can replace several drives at once only to rebuild a new RAID. Feedback from the Engineer Support of Dell that if we act with this, we will need to use a connection series for reset and reconfigure the EQL scratch all on again once. Is this true?

  Is there really no way to replace several drives in EQL without having to reset the entire system?

  We meet also restart and EQL will stop when he was not able to rebuild the RAID, taking the storage offline without giving any possibility to proceed. So we are forced to connect return old hard disks and wait for it to rebuild the RAID. And despite having zero data and zero volume, reconstruction takes always the hours to complete.

  Low-end NAS allow to remove the RAID and replace all disks while keeping the existing configuration. However, it seems that high-end EQL has no way to retain the existing configuration if need to replace multiple disks or RAID could not rebuild.

  Is there a way we can save the existing configuration, we can restore?

  Finally, it will be good if EQL could show what channel/RAID 50 each hard drive is a place where we can replace up to 4 HDDs without bringing the RAID rebuild process to a halt and cause a stop and restart again.

  A connect as that of grpadmin?

• Number of readers does take to make a RAID 6 in a Dell Equallogic PS6100E?

  Looking at the documentation for the PS6100E.  I use RAID 6.  The layout table starts to six discs.  Which is the minimum?  You can do this with four discs in an EQL?  Thank you.

  It's "RAID 6" DO RAID with 6 disks.    Sets of multiple RAID-6, this is what I was talking about.  Each physical array can be a single RAID level, using all the available discs.   A 'pool' can have up to 8 physical members in it.   The total space of all members will be available to the volumes in this pool.   You can have up to 4 pools by group.  You cannot split one of the physical group between multiple pools.

• Levels of raid Volumes Compellent

  Hello.

  We are looking into buying a Bay Compellent, Dell, but before I look for in its technology.

  Unfortunately, the few public records on the SC8000 are very brief.

  I'm looking for information how the table handles its raids, from what ive understood, when you create a volume, some data will be placed on raid 10, some on raid 5 and some might end up on raid6 (prioritization).

  But the definition of these levels of raid? They simply come from all disks of a certain type, say raid10 ssd and SAS - NL's raid6. or are they built raids more as how 3par manages the CPG, creating mini-raids out of pieces of different discs?

  HP also has a wealth of easily accessible information about the paintings of 3par, I can't find anything for compellent :(

  http://h20566.www2.HP.com/portal/site/hpsc/public/PSI/manualsResults?sp4ts.Oid=5044394&AC.admitted=1388181376886.876444892.199480143

  OK - if really it's better done in person with someone who can demo and animate the allocations of blocks for you.

  BUT

  Compellent storage virtualized Tier - so, for each level of storage (which are defined by the disks of like I/O features such as speed control, flash type, etc.) all of the devices used to treat each IO.  HDS let each LUN to have several RAID algorithms in use at the same time. The ideal on this would be to have write operations occur in RAID 10 (fastest to write) and read operations to get the RAID5/6 (more effective space). RAID types reserve NOT a specific amount of physical disks - but rather function as a method of organizing for blocks of different LUNS across all the disks in a pane.

  Data Progression (Tiering) extends this feature to allow volumes exist with blocks into several levels based on age and the activity of each block. The LUN is presented as there is no difference for servers based on the location of the data and the blocks can be shifted dynamically as criteria. Recently given Progression has been expanded to allow the mixing of writing optimized and read optimized Flash SSD levels that revolutionize the market tables around without resorting to the use of SSDS as a front-end cache. Data is transferred more quickly, then a normal progression among the readers of optimized for reading writing optimized SSD to keep performance levels greater than 100 K IOPS / s while valuing the cost differences inherent in MLC drives (they are cheaper).

  http://www.Dell.com/learn/us/en/qto08/shared-content~data-sheets~en/documents~Dell-Compellent-software-suite.PDF

  One thing that really sets storage Compellent, is that the license is NOT related to the material. If a controller SC8000 can be replaced without purchase of multiple licenses or invalidate the original license. The license is perpetual and abstract the hardware that is used. So if I have a HDS I bought 5 years through a license for all the features for 16 disks I can apply this license to SC8000 controllers and SSDS (up to 16 spare non-pieces) and start using it.

  I think that if you use this site as your jumping off point - http://www.dell.com/learn/us/en/04/dcm/flash-storage you will find a lot of information just look at software storage Center rather than the specific hardware building blocks.

• Setting up RAID on pair of internal IDE drives in a Dimension 2400

  I will first say that I do not know if this is possible.

  I have an old 2400 dimension which came with one hard disk of 40 GB. I want to buy a pair of larger disks to put in it and wonder if it's possible for me to create the pair with RAID-1 mirror, even if it would have the top OS? Ultimately, I want to set up multiple partitions and set it to dual-boot Windows and Linux flavor still to be decided.  I don't know yet what readers are compatible with this machine. I am hunting for the specifications for it. I will need to create a recovery media to preserve the Windows XP operating system, the machine was not provided with media.

  Someone on this forum has successfully completed what I'm doing? If you have any suggestions or can tell me all the good links online, it would be more helpful as I am still learning what I need to do to make this happen all. A link to the material sheet Dimension 2400 or compatible drives list would be welcome.

  Feel free to me blowing my lack of knowledge on this, but we must start somewhere and ask questions to find out what they don't know.

  Thanks in advance,

  The BIOS and the IDE controller integrated into the Dimension 2400 will not support RAID.  However, you can add a RAID PCI controller card that accepts SATA drives.  The SYBA-150R comes to mind for example, but a search of RAID PCI controller will be to others.

  The Dimension 2400 is a bit old for this sort of thing, unless you use it as a learning tool.  You might be better off looking for a somewhat newer machine, like a Dimension 9100, already a capable SATA controller for RAID.

  The incorporation of other operating systems is not a problem, provided that the selected OS has a compatible with the RAID controller mass storage driver.  When a RAID volume is established, the operating system simply treats it as if it were a single hard drive; individual readers are invisible.

  For more information on the Dimension 2400, see the following: Dimension 2400 manual repair

• Configuration of Raid M4X UCS C 240

  Can anyone know how to configure Raid on UCS C 240 M4 X model? I tried to run Ctrl + H while restarting, but I don't have any option of Ctrl + H so that UCS restart server. Server contain 6 disk of the 827 GB each. What Raid level, should I choose 5 or 6 (or other)? I tried to read Cisco docs but I don't have a lot of them.

  CUCM apps usually posted requirements for the required flow rate minimum of Mbps.

  Often, we see a mirror raid 1 2 drive for the operating system, then 4 or more drives Raid 5 that stores data warehouses main the guestVMs run from as a common configuration.

  By creating virtual drives (assuming you have HDs and not SSD) make sure that you set enable-write caching (with good BBU) and activate the cache before reading.

  We see sometimes raid 10 used, but which has a surcharge of 50% of raid and to do by multiples of 4.

  I see you found the MMIC storage tab, which is easier to use than time message option rom, Megaraid utility to create raid volumes.

  Once you have created your virtual disks (VDs), make sure you configure your boot order to include your local drive.

  Please see http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware regarding some of the app voice UC requirements.

• Best practices for the SSD + RAID?

  What should be the size of parity when running 2 x Samsung 850 SSD Pro connected to a H710P in a R720xd PE in a matrix RAID 1?

  Do not find as much information online information for this...

  Is there a whitepaper for it? something that could tell me the best settings when executing the SSD on the PERC H710 (p) - essentially all the configurable parameters when creating a DG/VD.

  Hello

  JW

  What should be the size of parity when running 2 x Samsung 850 SSD Pro connected to a H710P in a R720xd PE in a matrix RAID 1?

  RAID 1 is not a type of parity and you do not set a size of parity. I think you're talking about the size of the stripe.

  The size of the band does not have a big difference on a RAID 1. The size of distribution is most important when you spread data on multiple disks. The size of the stripe can have an impact on the performance of the table by spreading the data on the disks or by limiting access to the data to a single drive. By changing the band size, you can do your berries of access time or improve sequential access times. Smaller block sizes are generally better for sequential reads/writes as they spread usually given on several drives, and larger sizes of band segment are generally better for fast access times because the data, you have access to are usually on a single disc.

  In short, unless you are going to hire a consultant to analyze your use of data to recommend settings then I would leave it on by default. Change the size of the default distribution segment only would probably be useful in an environment of database with use of compatible file size and a RAID level across several drives.

  Thank you

• That means the AHCI Mode, Mode RAID & SATA IDE Mode in the BIOS settings means

  That means the AHCI Mode, Mode RAID & SATA IDE Mode in the BIOS settings means

  My computer is having problems when I bought all first it was from another provider which came as a set overclocked PC up the unit everything needed had to be put in my case & add existing hard drives & DVD etc. readers added on the implementation. I used the same location for more than 10 years before that I always built them myself I can build a good setup computer I correspond to different parts inside each other, and then he tested & sent.
  Unfortunately, the store has closed & the owner is sick cannot get their hands on him more & I had to get some add on things like new SSDS & some other bits in my system & the young boy said he would could do this job, but everything went wrong & I lost all new so I decided to recycle me like I used to do it before windows 7-64 came out I was going through a rough patch with me being paraplegic in any case it is difficult to build a new PC, so I chose this store & their confidence that went wrong now & I've been research & learn to catch up with the new technology, I do what I do anyway.
  Thing is my system is never one that you can purchase a manufacturer & I left it with the young boy & it came out all memory & was not necessary but of course upset of that ruined the setting completely overclocked so I did it myself & I got the work faster than ever, & quieter PC I just got the score that he had now , so I'm happy with it, but the names I came across while overclocking I came across that I'm not average or really lot as were dealing with Fast CrossfireX DDR RAM 1600 MHz.
  Please don't tell me that I should not be messing around with what I made since 1989 & made great strides in how everything works, I am not aware about this sort of thing I know SATA what it is & done, but those responsible for setting came from the part of overclocking in the BIOS I put then correctly , but I wanted to know what they represent in more depth. Thanks to anyone who can put me wise on these 3 points only. Malcolm.

  I'm pretty sure that you are on the wrong "forum" for this type of topic. This forum is designed as a support Pro-type Surface ultrabook/tablets and tablet-like Surface.

  That said,

  AHCI - Advanced Host Controller Interface - this is a hardware mechanism that allows the software to communicate with the devices Serial ATA (SATA). It offers features such as connecting hot and native command queuing (NCQ).

  IDE - Integrated Drive Electronics - IDE is basically the 'old' version of AHCI without connection to hot and NCQ. (It is usually used during the era the Parallel ATA (PATA) hard drives)

  Now. Mode AHCI and IDE mode - what is - this? IDE mode is to give you the greatest compatibility with older operating systems. AHCI is as I mentioned above, a modern version of the IDE - use the AHCI mode if you are running recent operating systems (Windows Vista + and Linux kernel 2.6.19+).) IDE mode will allow you to connect older operating systems with SATA drives.

  As I mentioned above, SATA is Serial ATA and the replacement of hard drives Parallel ATA (PATA).

  RAID - this is a storage technology where combine you multiple disks in a unit of 'single', depending on the mode, there may be RAID-0 and RAID-6 and each with different hard drive configurations. I will explain the simple examples: RAID-0 , which is the distribution but no parity or mirroring, this means that there is no data redundancy, if there is a failure on a disc, it will cause the loss of data on the entire RAID array. Ex: You 0110 as writing the data, 01 goes on disk 1 and 10 goes on disc 2, allowing a faster data read/write access.

  RAID-1- This is the opposite of RAID-0, which is mirrored without interlacing (no parity or the other). Basically, this means that you have an exact clone of disk 1 disk 2 disk 1 failure.

  RAID0 + 1 is that both RAID 1 and 0 is, IE interlacing (write data simultaneously to two [or more]. disks more mirroring failure) the minimum amount of disks required for this type of installation is 4 IDENTICAL drives.

  There is also RAID 2, 3, 4, 5, 6. That is just more implemented different configurations of distribution/parity/mirroring on disks.

  That being said, your RAID mode will allow you for some type of RAID configuration, if you choose to do so.

  Supplement: Many SATA controllers can enable AHCI separately or in combination with RAID support. Recommend Intel choose RAID mode on their motherboards, allowing also the AHCI, rather than AHCI/SATA mode for maximum flexibility (in the case that you ever want to build a RAID array), because there are a few problems that occurs, usually BSOD, when you choose a different mode once an operating system is already installed.

  Hello-

  You're not quite call things correctly.  There are 2 two different things you need to do:

  1. "point source" the .ps1 file in which the function is defined by doing something like: ".." c:\temp\functionDefinitionfilename.ps1 ".
  2. _then_, you must call the function name (not the name of the .ps1 file) and can pass parameters (such as "Get-VNVMHostLogicalVolumeInfo - VMHostName myvmhost0.dom.com"

  To article 0, you _must_ include the period and the space before the name of the file in which the function is defined.  This action is what makes the "Get-VNVMHostLogicalVolumeInfo" function available in your PowerShell session.  It is the "supply point".

  Then, for question 1, which is the function name, "Get-VNVMHostLogicalVolumeInfo", not the name of the definition of the function (the .ps1 file) file.  Until you do these two things, you will continue to get zero results.  You follow?

• Controller SCSI Raid ESXi 5.5 recommendation

  I'm moving the ESXi 5.5 to another server by using the following:

  
  

  Server Dell R610 with 12G of ram and a Dell PowerVaul 220 s Raid 5 with 12, space 1, 5 - T HD sata

  The Raid Controller is a Intel SRCU42E Ultra320 SCSI PCI-Express X 8 with ext 2 x 68pin ports.

  
  

  I get the error ' call 'HostDatastoreSystem. " 'Of object' CreateVmfsDatastore 'ha-datastoresystem' on ESXi when you try to add storage. I even installed 5.1 but with the same results.

  
  

  Later, after much research and troubleshooting, as well as headaches, I discover that the SCSI Raid card was not compatible with ESXI 5.1, 5.5 only with 4.1 or 4.0

  I begin to scan the cards SCSI RAID but difficult to get one with the above specifications that could be compatible with ESXI 5.5

  
  

  Run out of tricks and do not have the ability to turn the Dell PowerVault 220 s

  May suggest a SCSI Raid PCI - e card with a port Ext. 68pin compatible 5.1 to 5.5? All of the recommendations, difficulty, work around?

  Thank you

  ESXi 5.5 system requirements

  When you install or upgrade to ESXi 5.5, ensure that the host meets these minimum hardware configurations supported by ESXi 5.5:

  1. Your equipment is compatible on the VMware Compatibility Guide. This includes:
  • Systems compatibility
  • Compatibility I/O (network adapters and HBAS)
  • Storage compatibility
  • Backup software compatibility
• You have a 64-bit processor. VMware ESXi 5.5 only installs and runs on 64-bit x 86 CPU servers. He argues also that LAHF and SAHF CPU instructions.
• You have a computer with at least two hearts 5.5 ESXi host.
• The NX/XD bit is set for the CPU in the BIOS.
• Your processor is supported. ESXi supports a wide range of x 64 of multicore. For a complete list of taken processors supported,
• You have 4 GB of RAM. This is the minimum required to install ESXi 5.5. Provide at least 8 GB of RAM to take full advantage of the features of ESXi and run virtual machines in typical production environments.
• Support for hardware virtualization (Intel VT - x or AMD RVI) is enabled on x 64 CPU (to support 64-bit virtual machines). For a complete list of operating systems that are supported with ESXi, hosts running virtual machines with 64-bit operating systems have these hardware requirements:
  • For AMD Opteron systems, processors must be Opteron Rev E or later.
  • For Intel Xeon systems, processors must include support for Intel Virtualization Technology (VT). Many servers which may include processors with VT support VT disabled by default, so you have to manually enable VT. If your CPU support VT, but you do not see this option in the BIOS, contact your provider to request a version of BIOS that allows to enable VT support.

    Note: to determine if your server has 64-bit VMware support, download The utility of Identification of CPU on the VMware site.

• You have one or more Gigabit or 10 GB Ethernet controllers. For a list of network adapter models supported, refer to the VMware Compatibility Guide.
• You with any combination of one or more storage controllers are:
  • Basic SCSI controllers. Adaptec Ultra-160 or Ultra-320, LSI Logic Fusion-MPT and most NCR/Symbios SCSI.
  • RAID controllers. Reference Dell PERC (Adaptec RAID and LSI MegaRAID) RAID HP Smart Array or IBM ServeRAID controllers (Adaptec).
• You have a SCSI drive or a local, off-grid, RAID LUN with unpartitioned for VMS space.
• For Serial ATA (SATA), a drive connected through taken SAS controllers supported or supported integrated SATA controllers. SATA drives are supposed to be remote, no premises. These discs are not used as a partition to scrape by default because they are too far away.

  Note: you cannot connect a SATA CD-ROM device to a virtual machine on a host ESXi 5.5. To use the SATA CD-ROM device, you must use the IDE emulation mode.

• You use a supported storage system. ESXi 5.5 supports the installation and start-up of these storage systems:
  • SATA drives. SATA drives connected behind the SAS controllers supported or SATA controllers support built-in.
    • LSI1068E (LSISAS3442E)
    • LSI1068 (SAS 5)
    • IBM ServeRAID 8K SAS controller
    • Smart Array P400/256 controller
    • 5.0.1 Dell PERC controller
  • SATA drives. Support SATA edge include:
    • Intel ICH9
    • NVIDIA MCP55
    • ServerWorks HT1000

  Note: ESXi does not support using SATA internal disks local to the host server to create VMFS stores of data that is shared between multiple ESXi hosts.

• You have disks Serial Attached SCSI (SAS) supported for ESXi 5.5 installation and to store virtual machines in VMFS partitions.
• You have dedicated disk SAN Fibre Channel or iSCSI.
• You have USB devices supported for ESXi installation.
• You can install and start ESXi a FCoE LUN using VMware software FCoE adapters and network with FCoE adapters discharge capacity
. See the documentation for storage for more information about installing and initializing ESXi with vSphere FCoE software.
