The lack of certain cache/buffers and proper battery-backup for uncommitted transactions also make ICHR high-risk compared to "hardware RAID" solutions.

Windows can deal with this through its bootloader process and I imagine VMWare could as well but they never will because as others have pointed out, ICHR RAID isn't "pro grade" due to its lack of a dedicated parity processor (ICHR uses your x86 CPU which actually does an outstanding job when setup right) and the inherent dangers in that such as the fact that your CPU is a general purpose processor doing many other things making it FAR more prone to crashing than a dedicated parity processor. It does not provide a proper INT19 bootstrap loader and that means that the RAID volumes it presents can't be booted off of and in effect, don't really exist until the IAStor service starts, uses the ICHR driver to see the volumes, THEN presents them to the O/S. ICHR is an interesting hybrid solution where the SouthBridge chipset actually does provide firmware for the RAID and a BIOS where you can do some basic configuration.

The reason for this is because the raid doesn't exist as a volume to be exposed through a controller driver (the real explanation for what all the kids call "fakeraid").Īll RAID solutions are software-based, but what most call "hardware RAID" are solutions where the RAID software runs on the controller ("firmware") and so when you use a driver to allow your O/S (ESXi in this case) to see the volumes (non-RAID such as SATA, IDE, or Host Bus Adapters aka HBAs expose drives instead of volumes), then the O/S has a lot less work to do that with a more typical software RAID solution. No, you can't use Intel ICHR raid for vSphere/ESXi. On a production server, I would only consider this if like yours, the USB port is internal.

However, if you had a problem with your ESXi install or thumbstick, it doesn't take long to set up a new one then import the VM's. This should be able to let you know if a disk has failed via a popup and email.ĮSXi on a thumbstick - the thumbstick will probably be slower than booting from a RAID, and there is no redundancy for the ESXi host itself, just the VM's. If you read the intel link you provided, you will see from page 41 onwards the guide describes setting up a 2k8 server, installing RAID Web Console 2 on the server, then setting up the ESXi host. Really you want 15K SAS drives and a battery backed caching RAID controller. Green drives normally have a slower speed (rpm) and are set to spin down during periods of inactivity, regardless of whether the OS has told it to. However I've noticed you have chosen WD Green SATA drives - I would consider these a very poor choice.
I personally would say if the drives aren't going to see high IOPS (especially random IOPS) then RAID 5 would do. I think round here you will get many people suggesting an extra drive and RAID 10 rather than RAID 5 as the write performance is much higher under load.

There are unofficial drivers that you can install on ESXi to support additional hardware, including a "dmraid" one for Intel Matrix RAID (your chipset's fakeraid), but you're going out on a limb if you do that. Guests will only see their virtual disks.) Isolating guests from the host's hardware is half the point of virtualization. (The VMs will not be able to see the host's fakeraid controller. If you really want to use ESXi, you could set up your three drives as separate datastores, give each of your VMs three virtual disks - one from each datastore - and set up software RAID within each VM's operating system. You might want to opt for a different virtualization platform, such as Citrix XenServer or Linux KVM. ESXi should recognize drives connected to that controller, but only as standalone drives, not as a RAID array. ESXi doesn't support fakeraid, because it's aimed at enterprise environments (which use real hardware RAID for better performance), not consumer PCs (which use fakeraid because it's cheap). The RAID on that motherboard is not real hardware RAID, it's " fakeraid" that depends on drivers in the operating system.
