Hi Dale,
I always ask for more than I need so that I can do duplications, have more
downtime and room to grow. I always get requests that are unexpected and
find that some data is not covered. The extra capacity gets chewed up pretty
fast in my experience.
Sounds like you have a manageable environment. I miss my old one a lot, it
used to run smoothly all the time, I would just add new hosts/databases and
that was it.
I believe it's more to do with the OS than anything. My experience is that I
need to multiplex more windows clients than UNIX ones to get the desired
performance. If you are getting good performance then that's fantastic but
if not then it's always a bit of trial and error to get it up to scratch.
With the T2000 I would get the 8 core one, the rest are the misfit 8 cores
that came of the factory floor bad and they sell as 4-6 cores. 8GB of RAM
should be OK but more is always better. You can go up to 32 or 64Gb on those
but it costs a fortune.
The drives are expensive too, they're the new SAS ones which top out at 73GB
right now. One reason I like the V490 but you pay the price. You can get
320GB in them now.
Anyway, I guess you can attach some nice, fast disk trays to them or some
SAN disk. It's up to you I guess ?? Ideally, a fully loaded V890 full of
320GB drives would be a monster, they take the new 15K FCAL drives. I deal
for DSSUs and then stream to tape. But it's very expensive and probably
overkill for you.
Yes, the timeline is a bit short, last time I heard 6.5 was not coming out
until about July/Aug.
Hope it all goes well.
Dom

Hey Dom,
thanks for the reply.
You're right, 2 is possibly scraping the barrel a bit but personally I feel
6 would be overkill. The windows backup server (BackupExec 11d) for example
is connected to a Dell Powervault LTO3 changer (8 slots) and we cope without
a problem. I will put down 4 LTO 3's and then if more are needed I will
order. But yes, the 2TB is for a full weekend backup. Nightly inc's are
usually around the 300~400GB range.
Any particular reason for the slow output from the Windows client's? I can
pretty much saturate the 1GB link (private backup LAN) currently on the
clients without too much trouble.
Looked at the T2000, nice little box. Any particular config (CPU/RAM/HDD's)?
This project is likely to go ahead in the next 4~6 weeks so not too sure on
timelines for NB 6.5 or x64 support.
Cheers,
Dale
