VLANs and VSANs and...

Recent posts discussed the correctness of the term Virtualization in it's current use. Also the post on the "Storage Virtualization" which should actually be called some form of "Volume Manager" made me think of the next storage related network. The File Area Network, in which the file management problems are to be handled. I've been doing some reading in the new Brocade pocket book which I got at a recent "Brocade Fusion Tour" seminar, and this tought me that most file management issues are in the Windows environment. Where else I immediately thought. We…

Galaxy and ProtecTIER issues.

Today,I've come across some problems when configuring a Commvault Galaxy server to use the Diligent's Virtual Tape Facility including ProtecTIER. I thought you'd be interested. This applies to the Commvault Galaxy Media Agents for Windows for as far as I know. Another criteria, is that you have chosen to configure drives to be spread across two or more fibrechannel connections. When doing a standard detection in Galaxy, the library device and tape units are properly detected, and the units can be automatically configured into the corresponding drive slots in the library. While this…

When it gets hot, you need to cool it....but not to much...

In case someone missed my recent post on datacenter disasters in my neighbourhood, take a look at this. Just about a month or two ago, I presented our management with a new proposal for our TSM environment. The primairy server grew beyond acceptable limits, and AIX4 clients kept failing backups because the TSM server's software level was too advanced. So my proposal was accepted, and very soon we would start to implement the new TSM layout. We made a separate TSM server using an older version, so the remaining AIX4 servers could still be backed up. We temporarily…

I need to speak to my boss...

On a dutch Storage Magazine website, I read an article that was translated from this one. I was actually quite surprised by the salaries some guys in this industry seem to get.  I am proud to able to call myself a BCFP (Brocade Certified SAN Professinal) and CMSP (Certified McData SAN Professional), and some other certifications as well, but ... I think I have to schedule a meeting with my boss . Like I said before,  I am very happy with my life as it is, but it makes me think......…

We got us some new storage

After a couple of months of negotiation's and specification checking, we finally were able to place a new storage order for replacing our current IBM Sharks and DS4300 (fiber) disk systems. We decided to go for 1 kind of box, even though we could save money on some midrange storage systems. We have had our share of nasty experiences with the mid-range boxes, so we decided never to make any concessions on reliability again. For the next few years, we will be running our centralized data on IBM's DS8300 boxes. Two to be precise. One in…

It got hot, global warming?

According to hear-say information, the bigBlue datacenter in Bruxelles, Belgium was struck by fire last week. Their twin-center concept presumably did not work, and most of it's operations went dead. Even the high-availablity type applications seem to not have survived. I've been checking all possible resources, but I wasn't able to confirm this yet. A week or two before, A health insurance company was out of business for at least a week, also due to fire. Their CEO said something along this line when he was requested for DR budget; "What are the…

The best don't always win

The storage deal on disk replacement is over. A decision has been made. Are we happy? Sure, why not. Did we get what we want? Well, technically we had a better option, but financially, we couldn't refuse this final offer. The financial gap between the winner and the runner up, was just to big. The technological differences aren't enough to justify the extra investments. So we didn't get the best money could buy, but we did get a good deal, and we do get good storage for these euros. Besides, the big-iron players'…

Data deduplication

It has been a while, but here's something I am trying to figure out for some time now. We've bought a Diligent VTF with ProtecTIER (data deduplication on virtual tapes) in the first quarter this year. The main reason was that nice feature where we could store up to 25 times the amount of actual disk space we had available for virtual tape. Since then, almost all virtual tape vendors have some form of data deduplication. I guess this is a flaming hot feature. The big-irons are lagging behind a bit, but no doubt they will…
