Hey, absolutely.
I love the Qualstar LTO tape library we have. It's an XLS 832700. We have the
one LRM and two
MEM1's. When we first got it in 2007, we didn't know whether to trust the
library or NetWorker
about whether a tape was really in the drive, so we took the cartridge slots
off the doors so
we could see into the LRM and visually check (without opening the door) what
the drive status
was. That has been helpful, but the XLS has never lied to me about the status
of a tape drive
(while NetWorker is periodically confused). Anyway, we have capacity for 2,505
cartridges.
The tape library is rock solid, and after much work with EMC, NetWorker solidly
supports the
library now.
Same here. For the price Qualstar gets for its tape libraries, they are hard to
beat. I have a Qualstar 88132 model with 4 LTO-3 tape drives. It is a real
workhorse. We back up roughly 250 clients to it nightly with the four drives
connected to a Dell 2950 server running Red Hat Linux AS 4 and NetWorker 7.5.3.
Those four tape drives routinely see 80-90MB/sec throughput, which is pretty
good considering we only have two network drops on that server and no
disk-to-disk-to-tape involved.
Stan, where you say "for the price", do you mean that the prices are
reasonable, or minimally competitive, for what you're getting, or the
price is on the higher end but well worth the extra?
Also, what all (say, in a nutshell) was involved in getting it to work
with NW? I thought NW had long supported Qualstar, but maybe your's was
a newer model they'd not yet tested? Just curious.
