They have encryption capability in the drive, but it's not as simple as
just saying "encryption on". You have to have something to manage
I agree, in my environment I have not seen anything that can saturate a 2GB
FC link. I am thinking that choosing a drive with more speeds will give
improved "real-world" performance rather than a drive that can peak very
high. (although peaks of 180 MB/s would blow my socks off :) )
On 9/13/07,
The biggest problem is to have an architecture that can feed that
transfer rate .. because at those speed, one drive just saturates a
2 Gb FC link. ;op

Native drive speed of the T10K is 120 MB/s ... it is even closer to
130 MB/s..; so If you are using compression and you feed the data fast
enough you can go over the 170 MB/s.. I had peaks over the 180 MB/s

But that is just the read speed of the hard drives yeah? If the data

Yes. They've been out for about 5 months.

I don't use them, but I did some research.
One gotcha that I came across was the writing speed. They can only
write at either 120 MB/sec or 50 MB/sec. There is no
Does anyone have any experiences with the Sun/StorageTek T1 tape drive?
I am doing some research on a D2D2T solution that would include a secure
tape option. The T1 can do (supposedly) encryption at a device level.
