Re: [Veritas-bu] lto4 fc bottleneck

Or to
put it another way. The backplane of your switch is the limiting factor. If the
switch is oversubscribed(too many devices) it could become a
bottleneck.

You're mixing up bits and bytes. Your fibre hba is 1 Gb
(little b = bit). Your drives are capable of 120MB (big B =
byte). So you're trying to put 120MB of data down a roughly 100MB
pipe.
I'd say that for each LTO-4, you're going to need a dedicated 1Gb HBA or
upgrade the HBAs switch to 4Gbps and then you can get away with only 2 of
them.

I was running only six LTO4 drives that is capable of 120MB on a 1GB fiber
hba, would that be a bottleneck? 120 x 6 = 720MB even though the
switch is 1GB?
