For anyone using the good old Winscp client, it was just updated to 4.0.7. Same goes for mRemote, it has just been updated to version 1.35. Pick it up, and while your at it visit VM4All. Eric keeps track of all VMware related tools!
Fiber channel round-robin load balancing
There’s a nice article about “round-robin” load balancing on SystemsArchitech which got me a bit dazzled about this new functionality:
esxcfg-mpath – lun <*.lun> —policy custom –H minq –T any –C 0 –B 2048
The policy states that the LUN should utilize a custom policy that determines which (of two) HBA to utilize based on the minimum queue length. This HBA selection is triggered every 2048 blocks transmitted to a given LUN over the same target. The policy will use any targets available to either of the two HBAs. In using storage that manages host port load-balancing, LUNs will only have two paths (one per fabric) and the storage array will perform storage array host port balancing from within its own management. With other storage arrays it is typical to perform this host port balancing from the hosts accessing the given storage array.
With 10 ESX hosts set with this policy wouldn’t it probably cause path thrashing on an active/active SAN? You never know which controller will access a specific LUN and if your unlucky it will be switching from controller A to controller B every millisecond. Anyone else any thoughts on this new feature and the possible danger?
Error code 25036 during VirtualCenter installation
During the installation of VirtualCenter the following error code was presented “25036”. With no further message the installation is cut-off. After a close inspection it seemed that there already were a couple of SQL Express 2005 services installed, the software was removed and the services were still there but disabled. I guess for some reason the removal of SQL 2005 Express wasn’t successful. The installation procedure seems to have a hard time overwriting the registry values or changing the old values. This problem can easily be solved by manually deleting that specific service in the registry. (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services)
9″ Asus Eee PC!
Yeah, this is the one I’ve been waiting for a 9″ Asus Eee PC. The 7″ is a cool device, but lacks a decent screen resolution. This is probably fixed with the 9″. Asus has also added a 12GB flash disk instead of a 8GB flash disk. I really need to pick one up as soon as it becomes available in Europe.
