My half-loaded v880 is much like a v440. I've got 29 media servers, 155
clients, about 60 oracle instances, and I backed up 20TB last week. I've
had a request in to double my CPU's forever. 4 CPU's isnt' enough for this
volume.
I've got a doc I'll send you direct on NB Sizing.
That said, windows isn't as reliable or flexible. If you've been with this
forum a while, you'll find lots of notes from frustrated Windows admins
There's lots of Unix admins, too, but IMO, their problems get solved more
easily.
My $.02, go with Unix but not Linux - there's lots of issues with Linux as a
media server. Solaris for *everybody is running this* but, frankly, we've
been kicking Sun's but and wiping the floor afterward with AIX. It's a
strange little OS but it's darned fast.

Thanks Dave,
Our projected size requirement will be upto 300 clients and 15T total full.
Most of our policies will be 1 full and six incremental per week. Assuming
20% change for incrementals we'd be looking about 5 - 7T per 8hr night
backup window. That'd be roughly 230MBps. Would one V440 be able to handle
this kind of throughput? The management has an argument that one V440 cost
more than three Windows boxes with similar (or better) speed. But if one
V440 can handle the load and more stable the argument would be stronger for
us.
cheers
Guang

Well, I think it really depends on how much data you need to push to tape in
a given time frame and the growth you expect.
It is true that Sun leaves a bit to be desired in their rather low number of
high-speed buses (I suspect market forces determine that type of thing) but
if it meets your needs then I say stick with Sun. We use a number of v440's
for media servers and spec'd them to push about 12TB a day with 4-6 hours to
spare. This has been the case and the fiber connected drives we use operate
wonderfully in terms of speed across these buses.
I can say that in my experience tape drives in general are a lot less stable
on the Window's media servers that I've used, lots of ghost drives and
reboots are almost always part of fixing any little problem. Stick with a
Unix media server if at all possible.

Subject: [Veritas-bu] choice of master/media server platform
Hi all,
I know there were some debates before regarding OS choices for NBU
but I'd like to ask one particular question. This was coming from an
external consultant.
Background: I am a Unix guys so normally are biased towards
stability/flexibility etc of *nix. But the consultant told us that since
backups are mainly using I/Os, the buses should be an important deciding
factor as well. He went out and found that even the most expensive of Sun
servers tend to have PCI buses with 66MHZ only (most with 33MHZ) and most of
the Intel boxes have 133MHZ PCI buses. He strongly suggested that we pick
Windows for that.
Your opinions?
many thanks
Guang
