ESXi Server 5 für RAID Betrieb umrüsten (ASUS KC MA-D8 mit ASUS Pike)

Upgrade ESXi Server 5 for RAID operation (ASUS KC MA-D8 with ASUS Pike)

As already indicated, the KCMA-D8 is capable of running a RAID daughter card control to support hardware RAID. The time to do this has now arrived. My ESXi has been running for quite some time with 4 2GB hard drives from Hitachi that are designed to run in a RAID. ASUS provides for its motherboard various models of the Pike card:
– ASUS Pike 2008 for RAID levels 0,1,10
– ASUS Pike 2008/IMR for RAID levels 0,1,5,10
– ASUS Pike 2008 for RAID levels 0,1,5,10 and onboard cache
Unfortunately, there is little evidence or even tests on the net about the performance influence on the vmware guest of running a RAID on the ESXi host

Maybe I’ll try different RAID levels once, only to be able to run a performance test. That is, 4 drives in RAID 0, RAID 10 and RAID 5

Upgrade ESXi Server from v 4.1 to v 5 (ASUS KCMA-D8)

Ok,
here’s the plan.
The ESXi 4.1 is installed on a USB stick.
Attached to my ESXi 4 are 4 SATA disks on one are actually only ISO-images, one is for storing VM machine and a VM disk is active. The plan is to install a RAID later times there.

The question is whether to “migrate” (install the 5 over the 4 aka “migrating”) or to to a fresh install of version 5. Not knowing if the motherboard and everything else is supportet.
The plan therefore is the following:
– Shutdown ESXi 4.1
– Detach the SATA disky
– Install v5
– e-attach an “unendangered” disk (eg with the ISO’s)
– Does everything work?
– If so, then add the other disks and tighten the configuration of the VM inventory
– If not, then the old USB stick should g back, power up the old system and search for a better way …
-> USB image backup pull
-> Move the image to second stick
-> Test the second stick
-> Try it
-> Migration

Well, here’s what I did:

0) documatation of the configuration of the virtual machine
1) Attempts to make an image of the USB stick (USB Image Tool from Alexander Beug), restore the image to a 2nd usb stick. The new stick unfortunately was not bootable. With “Image-copy” is here probably meant just the files.
2) Put an emptyy USB stick into the system, the v5 installation CD into a external USB DVD-ROm. SATA drives disconnected. Start the ESXi ISO v5 installation.
3) The installation went relatively smooth. No problems.
4) I installed theclient on a laptop the new client and tested the connection. Unlike the ESXi4: a second network card is now seen as “redundant network connection”, apparently I can not configure a separate network with separate virtual switched network.
5) Everything went well. Import the license. In the client go to “Configuration> Licensed Features and then click Edit License (have previously created with vmware.com at hand) and enter it.
6) Enable Virtual Machine again (after documentation from point 0) and everything is ready to go.

The compatibility with the ASUS KCMA-D8 is fine. No problems at all.

Hello world!

Welcome to my blog universe . Everything here is a bit influenced technologically that has to do with my career. and my hobby. At least with one of my hobbies. And yes, this is the first article. Until I start really, it takes some time but now I'm off and trying to leave important things for posterity 😉 Andrew.
