Re: [Veritas-bu] NDMP/isilon throughput question
2013-02-26 15:46:13
Currently I have two EMC Celerra NS120's, and I use 3-way NDMP
direct to
tape to back them up. This works reasonably well and I get reported
throughput of 90MB/sec on multiple streams.
I'm looking at buying an Isilon system (3x X200), and am considering
whether to continue to use 3-way NDMP (and buy isilon's fibre channel
backup appliance to do so), move to 2-way NDMP, or possibly something
else.
In particular I'm wondering about what kind of performance I can
expect
with 2-way NDMP.
...and as i read some docs I think I've gotten the meaning of
2-way and
3-way NDMP confused.
current setup: EMC NS120's are connected by fibre channel to the tape
drives. netbackup server is only doing control, no data traffic goes
through the netbackup server.
proposed setup: isilon sends data over ethernet to netbackup server,
which writes data to tape via fibre channel.
