In a galaxy, far far away...

There was a storage administrator, whose life was perfect. He managed a multivendor storage environment, where all the operating systems natively provided hardware independent multipathing to those RAID replacements the RM.com bloggers designed in the earth year 2006. All the storage subsystems available on the market were supported on all operating systems, and all migrations from one vendor to the other could be scheduled and completed without host/application disruption. He never has to convince any server operator to upgrade the multipathing software or have him remove any vendors specific multipathing software, reboot, install a new vendors specific multipathing…

Microsoft's VSS and IBM's FlashCopy.

I just read this post on SANgod.com. I must admit, you have to have some balls to call yourself a god , but if it works for him..... But i had a deja-vu when reading it. We don't use EMC, but the issues we have with M$ VSS and FlashCopy are about the same. I did some integration of VSS to the IBM San Volume Controller, just to try it out. We use IBM's Tivoli Storage Manager for backup, but in fact, that doesn't even matter. Consider a M$ Windows Server 2003 host, booting…

SAN Storage in a DMZ, Part 2.

Remember my post on SAN storage in a DMZ? If not, check this link. Well, i haven't been wasting my time. I've done some research on this topic, but that didn't turn up much information. Maybe my research wasn't extensive enough . I've had some thoughts on the subject though. Like i said in my previous post, you have to be pretty good to modify the device drivers of a host after breaking in. You'd have to be even better when trying to modify any SAN component or setting…

Friday afternoon motivation

Damn, It is happening to me again. It's friday afternoon, just a few hours before the weekend starts. I still got a lot of work, and many new ideas are roaming through my head. But i just don't seem to find the right place to start. Shall i wait on the people preparing stuff for me, or will i pick up stuff that need to be done anyway? If i start something new now, i probably won't be able to finish it before end-of-workday. All this seems to have a negative influence on my…
