My irregular “Virtualization Short Takes” series was put on hold some time ago after I started work on Mastering VMware vSphere 4. Now that work on the book is starting to wind down just a bit, I thought it would be a good time to try to resurrect the series. So, without further delay, welcome to the return of Virtualization Short Takes!
- Trigged by a series of blog posts by Arnim van Lieshout on VMware ESX memory management (Part 1, Part 2, and Part 3), Scott Herold decided to join the fray with this blog post. Both Scott’s post and Arnim’s posts are good reading for anyone interested in getting a better idea of what’s happening “under the covers,” so to speak, when it comes to memory management.
- Perhaps prompted by my post on upgrading virtual machines in vSphere, a lot of information has come to light regarding the PVSCSI driver. Some are advocating changes to best practices to incorporate the PVSCSI driver, but others seem to be questioning the need to move away from a single drive model (a necessary move since PVSCSI isn’t supported for boot drives). Personally, I just want VMware to support the PVSCSI driver on boot drives.
- Eric Sloof confirms for us that name resolution is still the Achilles’ Heel of VMware High Availability in VMware vSphere.
- I don’t remember where I picked up this VMware KB article, but it sure would be handy if VMware could provide more information about the issue, such as what CPUs might be affected. Otherwise, you’re kind of shooting in the dark, aren’t you?
- Upgraded to VMware vSphere, and now having issues with VMotion? Thanks to VMwarewolf, this pair of VMware KB articles (here and here) might help resolve the issue.
- Chad Sakac of EMC and co-conspirator for the storage portion of Mastering VMware vSphere 4 (pre-order here), has been putting out some very good posts:
- More on Exchange on vSphere (including FT)
- Integrated vSphere enterprise workloads – all together, at scale
- Using vSphere and HW offload for improved Celerra VSA performance
- vSphere and 2TB LUNs – changes from VI3.x
OK, I guess that should just about do it. Thanks for reading, and please share your thoughts, interesting links, or (pertinent) rants in the comments.
