Hi all
I just want to gauge from you your opinions on TSM using a VTL.
I started a thread a long time ago and got mixed reviews, some saying TSM should not be used with a VTL others saying go for it.
We had EMC in and take a look at our environment and recommend their VTL solution, then we had IBM in and they recommended LTO4 technology...
Sepaton sent me information too
The nice thing about VTL in my opinion is potentially quick recovery time, with tape, not so much.
I actually figured out how long it would take to restore our file server (over 1TB) using our current LTO2 technology (approx 35MB/s on hardware) not allocating tape mounts, latency, using 1 drive, it will take 26 days straight to restore.
that is were VTL trumps tape, in theory it should write and read as fast as the disk, however there has to be gotchas there, bottlenecks, how much tweaking on the tsm server and or clients need to be done to keep up with fast disk.
then there is traditional tape, a tried and true solution. tapes are removable, and cheap, but slow...
i read and hear about all the goods things with both, but am having a hard time finding the bad... possibly my google skills are lax.
anywho, let me know what you all think.
Unfortunatly, our budget this year does not allocate for either solution, you win some and lose some...
