vSphere Upgrade Saga: Exchanging HP BL460c G6 with BL460c G8

I recently received a pair of Gen8 blades for my enclosure and it is time to change out my Gen6 and 7 blades for Gen8. Now, just like every upgrade, there is a fair amount of planning that must happen in order to start the upgrade. I consider this a hardware upgrade and while it should be straight forward, you cannot just simply swap the blades, so much for the easy way.

vSphere Upgrade Saga: Planning for vSphere 6.0

There are many features in vSphere 6.0, such as multi-vCPU Fault Tolerance, that I wish to use for my VMware vCenter Server Appliance (vCSA), as it is the single point of failure. Backups have been made, but they will take quite a while to restore. With the new Fault Tolerance, there is a chance that restore might not be needed, thereby speeding up my recovery. vSphere 6.0 also includes improvements for NSX, VSAN, such as VMCP, long distance vMotion, VVOLs, changes to SSO deployment, and many other existing features, as well as a new web client. All of these make upgrading to 6.0 a worthwhile task. But to do so, you need to first make some preparations. Continue reading vSphere Upgrade Saga: Planning for vSphere 6.0

vSphere Upgrade Saga: Update Order

I have collected quite a few updates over the last few weeks since VMworld ended, and now I should make them. However, the most important non-security update for me is the one for VMware Horizon View. My View environment is old, and though it is maintained, I am in need of several upgrades to Windows, View, and underlying bits. Given that I have nearly everything installed within my environment (except vCAC and vCD at the moment), it is time to find the proper upgrade order.

RHEV Upgrade Saga: RHEL 7 Licensing and RHEV Support

While continuing on my way toward getting a fully running RHEV set up on RHEL 7, I find myself facing two new problems. Neither has a simple solution. The first is the lack of support in RHEV for RHEL 7 as a hypervisor. The second concerns a change in Red Hat’s handling of virtualization licenses. Solving these issues will entail making some hard choices or spending lots of money.

vSphere Upgrade Saga: Upgrading for VSAN

In order to use cache enhanced storage such as vFRC, VSAN, PernixData, SanDisk, etc., I had to upgrade my hardware to support better storage controllers that actually recognize SSDs as something more than just plain disks. For my environment, I had to replace my storage blades with something better that contained a supported storage controller. In addition, some new drives will be in order for those storage blades.

RHEV Upgrade Saga: Installing Open vSwitch on RHEL 7

I was finally going to install RHEV on my brand-new system running RHEL 7 RC with KVM. However, it has a dependency on DNS. Which was fine, but my DNS server was on another network, not the private network used by KVM with the standard virtual bridge. To fix this, I chose to move my KVM installation to use Open vSwitch. I have written before about adding Open vSwitch to KVM as well as hooking VMs to the Open vSwitch; however, Open vSwitch 2.1 has its own idiosyncrasies, as does libvirt 1.1.
