We've outgrown our Sun StorEdge L40 with 2 DLT7000 drives and 40 slots.
Our Netbackup Datacenter server is also old and failing. We will be
upgrading NBU 3.4.1 to 5.0, adding a 2-drive SDLT jukebox (keeping the
old jukebox too) and replacing the server.
Originally, I thought we might buy 2 servers (possibly Linux-based dual
Xeons), one to drive each jukebox. But Veritas licensing structure &
costs may make this expensive.
Our existing jukebox can write at 10MB/sec with both drives spinning.
The new jukebox will hopefully write at 64-72MB/sec with both drives
spinning.
If I sufficiently beef up a single server with dual-channel SCSI (i.e.
Adaptec 39160) and extra RAM, could I use a single server to drive both
jukeboxes? This should be cheaper (I could use my existing single
server license) and simpler to manage, but I don't want performance to
suffer and I'm assuming the 160MB/sec SCSI connection won't be a
bottleneck. (This also assumes we'll be able to implement a gigabit
backup LAN that performs fast enough to push both jukeboxes.)
Thanks in advance,
-Adam
