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.

  • 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.

  • Rufus (free utility) takes 2 minutes to create a USB bootable for ESXi installation starting source who becomes the target of the installation, even for 5.5

    Just info, one of these open Windows source rare beads that are becoming more and more difficult to find on the web these days, in the middle of a see payloads of downloader.

    Rufus I found to be very convenient for the quick creation of a USB flash drive you can start from, and then only install, for ESXi, no command-line stuff to memorize necessary and very fast:

    TinkerTry.com/rufus-takes-2-minutes-to-create-a-bootable-usb-flash-drive-for-esxi-installation

    works very well with ESXi 5.5 also:

    and when finished with this flash drive and you want to use it for something else (but normal reformatting does not work), she who manages, even on Windows 8.1:

    TinkerTry.com/rufus-lets-you-quickly-and-easily-reformat-an-esxi-usb-flash-drive-back-to-full-capacity

    Especially useful for people to start who shy away from Linux VMware procedure:

    Format a USB to start the ESXi Installation or upgrade

    Windows diskpart commands or potentially dangerous. Really fair, fast and useful for pretty much everyone.

  • How do I configure Openfiler for ESXi 5.0 (on which has been installed in the workstation).

    9.0 pre-installed VMware I installed in my laptop. I created a 5.0 as a VM ESXi in workstation. And I installed vSphere client 5.0 in my laptop. And I am able to access ESXi from my laptop through the vSphere client.

    Now, I created a VM with Windows 2008 R2 on top of ESXi. I installed vCenter 5.0 in Windows 2008 R2 Machine. I have just to connect to vCenter using vSphere client (which has been installed in my laptop) and added ESXi as host in the inventory.

    Now, I created a VM with Openfiler. Everything is fine. I want to use this Openfiler as a storage array, and I want the SAN with ESXi and Openfiler configuration.

    I think I need to create a VMkernel port group and attach that Openfiler VM who. And if I want to access the Openfiler web interface, do I need to have internet access? We can access the Openfiler Web interface without having access to the internet?

    Can someone let me know how to connect this Openfiler as a storage Bay for ESXi and configure a San.

    Openfiler does not need Internet access and you do not require an additional VMkernel port for access.  If it's production, you share the management and traffic on NIC iSCSI physical separate and thus vmkernel ports.  In this case, it is not necessary.  Did you do the initial installation of Openfiler to create a LUN for the ESXi host access?

  • DRS necessary for Resource Pools? (vSphere 5)

    Hello

    We make the leap of XenServer to VMWare at the minute and watch vSphere Standard as a starting block.

    I am looking to use Pools of resources in order to manage resources - is this correct for resource pools work I need DRS (which isn't available in the package of the company)?

    If so, should I still DRS to reserves, limits and shares for each VM?

    Thank you

    Tim

    Hi Tim,.

    the use of resource within a Cluster HA pools to Drs without DRS you can create pools of resource for single guests only.

    DRS is not necessary for reservations, the limits of virtual machines.

    For more information on the management of the resource, check out this doc:

    http://pubs.VMware.com/vSphere-50/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-501-resource-management-guide.PDF

  • 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...
