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.

  • Help please, conversion devices for ESXi .ovf hard

    We have just installed ESXi and it's my job to import all our VMServer devices to the ESXi.

    I have read several forums/blogs different on the conversion of the .vmx .ovf using ovf tool, as well as I have read about VMware Converter as well but haven't tried this as yet, everyone knows success with this.

    The ovf tool I can convert successfully to a .ovf file but when it came time to import on the ESXi Server I get the following error.

    "The OVF package cananot be imported on the selected host.

    The FVO contains an IDE hard drive, which is not supported: disk 1 "

    Anyone have any suggestions for a solution to this problem?

    Thank you in advance.

    For the source to try it with the other and then access the VMX file and for the use of VMware Virtual Machine infrastructure destination and on the next screen, you will get the screen to connect to your ESXi host.

  • Controller Raid SATA for Satellite P850

    Hi all

    We bought a Satellite P850 with Windows 7 Home Premium on it. Because we are a business, we wanted to install Professional on this topic. It seemed to work the first time tempted, but now even if BIOS can see the hard drive, installing windows can't find a driver for the disk controller if I use the following actions - disk Windows 7 Pro OEM, Windows 7 Volume License Upgrade disc, Windows 7 Home Premium - and trying to extract the pilot out of the driver Chipset Windows does not give any joy either.

    Can someone let me know the following:
    What is the Chipset on the device?
    What disk controller is necessary?
    If I can find one of these I can get the direct driver of intel
    If they found a driver to work with the controller and if yes where can I get a copy?

    > trying to extract the pilot out of the Chipset Windows driver don't give not any what joy either.

    You used the wrong driver.
    You need t to add the driver chipset during the Windows 7 installation process, but must be added the Intel Rapid Storage Technology driver

    On the page of the Toshiba UE driver you can find the 11.0.0.1032 for Win 7 64 bit version.
    This driver must be placed on the USB key and during the installation process you will be asked to add drivers.
    You must connect the USB and should add this driver.

  • Necessary for ESXi 5.0 RAID?

    Hi all

    I am quite new to this VMware and it's our first test of society on the implementation of the VM solution to our test environment.

    So please be generous if my question is redundant or I'm a bad advice.

    Our server is HP Proliant DL380 G5 server, and we bought the license VMware Essential Kit.  (installing ESXi 5.0 planning)

    As most of you already know, HP servers have this thing SmartStart which helps the user RAID disks before installing so that cases of dysfunction of a disk, the mirror will do its job until the fix.

    But when I was reading the other articles, it is said that esxi will not recognize software RAID?

    Also, no ESXi have some type of built in resources distribution system that allows virtual machines to function even if one or two hosts readers a malfunction?

    Corrections, suggestions and questions are welcome.

    Moreover, since it is the test environment, HP box is the only host (about 3.8 TB) and we intend to run about 4 ~ 5 VMs.

    Thank you

    Welcome to the community,

    most of the DL380 G5 models come with a built in P400 SmartArray RAID controller, which is a hardware RAID controller supported. The RAID functionality is completely transparent for ESXi in this case (for example, rebuilding after a fialure). So nothing to worry about this controller

    Regarding the size of disk/RAID you mentioned, you may need to divide the RAID in several logical volumes using the ACU (Array Configuration Utility) as a result of a problem with the currently used driver (see http://kb.vmware.com/kb/2006942). I would recommend that you create a logical volume of 10 GB for ESXi and divide the disc space remaining in two logical volumes for use VMFS data warehouses.

    BTW. the controller has BBWC (battery backed write cache)? This is very important and makes a HUGE difference in the performance of the disk.

  • Best way to set up 6 1 TB SATA disks for ESXi performance than

    Hi, the ESXi server must run a large number of different virtual machines at the same time and trying to figure out the best way to install the drives.

    Should I configure RAID 10 and use to install ESXI and VMs.

    A mirror then the other two for the swap file.

    or

    RAID configuration 10 for ESXI and VMs and then use the other two as JBOD drives and distributed the files for the exchange between these two drives?

    You can probably do so because of SATA for some time provided you get the hardware RAID with a BBWC map.

    If you are using a sata controller not expensive or one without the same dough RAID 10 is going to be pretty useless after about 4 VM.

    I build and run on the controllers to the House and it just was not worth the power used to run the commands, even in RAID 10.

    Ended up buying the battery off ebay for $150 and then it was usable...

  • 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.

    Hello

    You will find on the page of the Toshiba EU pilot the AHCI driver packs for Win 7 32 bit / 64 bit and win 8. There is no driver for the chipset AMD in Win XP.

    It seems that AMD does not Win XP AHCI/RAID/SATA drivers for this chipset.

    However, download the version of Win 7.
    Unzip the package. Now, you'll see an exe file. It's a package too.
    Right-click on the exe (TC40115700D) and extract the package.

    Now, go to:
    TC40115700D-packages-> drivers >-> SBDrv->-> AHCI SB7xx
    There you will find the files amd_sata/driver

    But again: not quite sure if Win XP would be able to manage it.

  • 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.

  • Dell PE 2850 Raid config for ESXi4

    We have a few spare Dell PE 2850 and will be installing ESXi 4. I was wondering what would be the best config. RAID 1 for the 2 first discs and then raid 5 for the rest of the raid just 5 all the way together.

    Thank you

    Out of these two options, it is greatly preferable to use one large set.

    However, performance will be better with a RAID-10 set.  Anyway, the controller must have a pile of work on the PERC.

    Please give points for any helpful answer.

  • PowerEdge 1900 and Poweredge 840 and NO hardware RAID SATA HD, FreeNAS with ZFS

    I searched these forums and the web in general a concise my questions answer, but nothing is done.  I just happen to find someone who is using 'old' technology and it retarget as much as you might think (I am a broke student by the way).

    I bought a Poweredge 1900 Server & server Poweredge 840 ebay about last year.  I've been busy and have yet to work with these two units.  I wanted to use the PE 1900 as a file server and then push a backup of these files on the server off site, the PE840.  I intended to buy four 1 TB or four disks SATA 2 to (WD Black or RED WD) for each system, respectively.

    I've been through a few videos on youtube the other day and discovered FreeNAS.  This seems to be a much better solution than the use of Ubuntu Server, but it also made me think about the hardware Raid with these systems.  If FreeNAS uses ZFS (software raid controller), you want to avoid a hardware raid controller.

    My current assumptions, please correct me if I'm wrong on any of the following:

    I think that each of these systems to support drives up to 2 TB?, I think that I can use the SATA drives and not SAS, four discs in each system drives.

    I believe that I can boot from USB flash drive (a quick, which I intend to install FreeNAS on which they recommend)

    I think I can connect readers to the Perc/Raid Controller controller (& just turn 'off' RAID), or simply directly on the motherboard.  (What woud be the advantages/disadvantages of the use of the card or simply by using the Council)

    I intend on working with what I have right now (cheap and available), then once I get this configuration work that I take it out of the sand/lab sandbox, upgrade the processors and ram up my budget will allow and go live with the installation program (if it is still possible)

    From now on, they are sitting in a corner, begging to consume energy, and fans of polute the soundscape with their cries (PE1900 precisely).  I know that I could pursue other options but I already these two units.

    I really want to utilze FreeNAS its serving capacity file and ZFS for its reliability.  Is it possible with this camera?, or should I junk them and move on?

    Thank you for your answer!

    I've done some research more and since FreeNAS is built off of FreeBSD supported hardware is the same.  I couldn't find a list for FreeNAS specifically so I looked to FreeBSD.  I was still confused about the material and decided to go forward with the poweredge 840, for two reaasons, there already 8 GB of ram and it is not as heavy to move on (from 1900). I shoot the raid controller (for simplicity) and I plugged in three 250 GB SATA drives and a 40 GB SSD.  I had to set the bios for the usb key is recognized and also due to adapt to be considered as a hard drive, then had to define the sequence of boot to the usb drive, acting as a hard drive.  Once all that has been said and done, I wrote my FreeNAS image on my USB and booted up.

    It took maybe 10 minutes and I was up and running (once I had configured the hardware and bios), I created a RaidZ (as proposed FreeNAS) and with my three 250 GB drives, it produced 453 GB of usable disk space.  The 40 GB SSD is used as L2ARC (from my cache of understanding), I tried the installer with and without the 40 GB SSD.  The difference was impressive, just opening the photos or streaming video on my laptop Win 8.1 (Dell 17r) is almost flawless, as if the files were stored locally.

    I was impressed by how quick and easy to use FreeNAS, simple and fast network shares can be configured with permissions that works quite simply not in less than 5 minutes.  I don't have Windows Server down, but generally configuration active directory takes a little more effort.

    I am satisfied for the moment and continues to experiment with the Poweredge 840 until I commit to a processor upgrade.  Once I acquire 16 GB memory for my Poweredge 1900 I will perform with her, as it has only 1 GB now, crazy.

    Thank you for your help.

    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.

  • Service profile of the CISCO UCS for ESXi

    Do you need multiple boot LUN on the storage array for each host that you want to apply the service profile to? I'm just confused, let's say I have 12 blades that I want to designate as boot SAN for ESXi, y aura-t 12 profiles of separate service for each of them, and will need me 12 different LUNS on our storage? I am new to this and I just want to make it as clean as possible! Any help is appreciated.

    Hi Justin,

    You can have the same LUN ID for multiple service profiles, as well as the same target ID. However, your initiators will be different and you will need to configure the zoning on your switch upstream if you use the end host mode.

    Here is a good guide, review the basics and how to put in place.
