Re: [Veritas-bu] Master Server on a SUN Thumper?

Put a VTL in front of it. The way VTLs lay data down on disk is more efficient than the way NBU writes data to a filesystem. The latter will cause fragmentation over time and the former will not.

There are a number of companies that will sell you a VTL head or software you can put in your own head, that you can then put in front of your Cx array. (EMC will not, BTW. They will want you to buy the CDL/EDL, which is prepackaged.)

We've using Clariion Cx300 with ATA drives for disk staging and performance is awful; seems to deteriorate over time. Currently RAID5 LUNs (tried RAID3 which had similar performance and even tested RAID0 which wasn't noticeably better). I'm assuming the performance issue is that with lots of different types of backups going to the array, we're making them jump all over the place, but haven't really found a way of improving it.

Actually we have some quite large (2TB+) Oracle Test/Trng databases using ATA drives in a Clariion CX700 arrays and get decent performance out of those. Of course that is hardware RAID. Not sure what the SUN Thumper uses.

The database on NBU is relatively small by comparison though at the moment we do still have ours on EMC Symmetrix (DMX3) but that is more for the warm fuzzy we get from Symmetrix reliability.

Just as an aside, how many people are building Master servers on SATA?

The master server is one big flat-file database. Why would you want it on SATA? I don't imagine that many database operations are going to any fun at all...

You could, on the other hand, put a DSSU or DSU on your master on SATA but that would be providing media server functionality, not master server functionality. I'd be okay with doing that (and am doing it here).
