My infrastructure recently underwent a catastrophic failure from which recovery was more tedious than difficult. An iSCSI server running from a KVM server using Open vSwitch decided to go south. Why? I am still trying to figure that out. The long and short of it is that Open vSwitch running within a CentOS 7 KVM has a pretty major performance glitch. I hope to fix that soon. So, what happened?
I have had HP StoreVirtual (LeftHand) licenses for some time now, but the previous versions were nearly impossible to install. At least, I could not discover the magic incantation to make them work, so I decided to put that upgrade on hold. Now that 11.0 has come out, as have a host of installers for various hypervisors, I will be giving it another shot. Assuming it installs, it will allow an additional 4TBs to be available to my infrastructure. I am running pretty close to the limits on my current datastores.

I have previously written about upgrading HPSIM and installing HP specific offline bundles within my vSphere environment. This was to increase the integration between vCenter, vCloud Director, and my physical hardware. Still, everything was not integrated well enough. Here’s what I did to make this work.
While technically not part of my vCloud environment, I use an Iomega ix2-200 as my tertiary storage for ISOs used within my vCloud environment. I also use an 8TB iSCSI server that also acts as my RHEV server. I will be upgrading this later as well with a 10G network card and the latest RHEV. However, this is about my Iomega ix2-200.
1TB is just not enough storage.
Of all the upgrades I have done to date, this was by far the easiest. Perhaps it was practice or even VMware vSphere’s time in market, but the upgrade to vSphere ESXi 5.1 from v4.1 and v5.0 went flawlessly.
It has once more come time to upgrade my hosts with security patches and I have run into one more, but easily worked around issue. Some VMs do not migrate or power-off when entering maintenance mode. These VMs include vShield per host appliances, and surprisingly vCops. Continue reading vSphere Upgrade Saga: ESXi 5 Upgrades with vShield and vCops
