Virtual Storage Integrator for Hyper-V

Most of my virtualization focus centers on VMware and its product portfolio, but VMware isn’t the only virtualization solution in town. I’m sure they (VMware) probably wish they were the only solution in town, but competition keeps everyone on their toes. (Consider Proverbs 27:17.)

Fixing Inactive New Paths on an EMC CLARiiON

I ran into an issue in the lab today with some VMware ESX 4.0 hosts and some older CLARiiON CX3 arrays. I’d been working to fix up the lab so that it more properly reflects a “best practices” configuration with dual SAN fabrics, dual-homed HBAs and CNAs, network connections spread across multiple physical switches, etc.—you know, all the wonderful things that we recommend to our customers.

vMotion Layer 2 Adjacency Requirement

The topic of vMotion, it’s practicality, and Layer 2 adjacency for vMotion has been a topic I’ve visited a few times over the last several months. The trend got kicked off with a post on vMotion reality, in which I attempted to debunk an article claiming vMotion was only a myth. The series continued with a discussion of the practicality of vMotion, where I again discussed the various Layer 2 requirements for vMotion.

Storage vMotion with RDMs

I recently had a colleague contact me with a question about raw device mappings (RDMs) and Storage vMotion. This colleague was trying to perform a Storage vMotion operation on a VM that also had a RDM attached and was running into a problem where the operation was failing because the destination datastore did not have sufficient space. In this case, the free space was less than the size of the mapped raw LUN, and this colleague couldn’t perform a Storage vMotion as a result. The colleague was surprised; he didn’t expect that behavior.

Some UCS Links

Nothing too terribly new or innovative here; I just had some Cisco UCS-related links I wanted to share with everyone. I hope that you find something useful here.

Technology Short Take #1

I’ve decided to discontinue the Virtualization Short Takes series and replace it with a new series that incorporates items from the networking and storage realms as well. In truth, I was already doing a little bit of that anyway, but this will expand and formalize the coverage a bit. I’d love to hear your feedback on this new series, to help me ensure that I’m providing useful and pertinent information and to help me ensure that I’m presenting it in the most efficient way. So, please speak up in the comments if you have any suggestions for improvement. Thanks!

Changing RDP Settings in VMware View Open Client for Mac

I’ve been using the VMware View Open Client for Mac OS X for a few weeks now, ever since I was approved to participate in EMC’s pilot VDI program. The one thing that I don’t like about the View Open Client is how it leverages the Mac-native Remote Desktop Connection application to make connections to the View hosted desktops. It does so in a way that makes it impossible to customize the behavior of the RDP session—or so I thought.
