RE: LTO 7 availability date

There was a significant performance improvement from LTO3 to LTO4. LTO5 and
beyond have had incremental improvements that are notable but not exciting.

If you really need a performance improvement, then a VTL should be
considered. The SPHiNX (Crossroads Systems) unit runs at the same speed
or better than LTO6 but you can set whatever size tape you would like. I'm
sure others do as well, but that's the one I have.

I agree that most IBM i shops will not need more than LTO4. One of the
exceptions being the additional redundancy capabilities supported by LTO 5
and above recently announced by IBM. My boss thinks that our reliability is
"good enough".

One thing I often notice is that there are charts which show how much data
will fit on each generation of LTO tapes, and, what the transfer rate of
each drive is also. What I am not seeing is those tables having any bearing
here. For example, I believe LTO4 was supposed to be twice as fast as LTO
3. We didn't see near that increase.

Agreed. But this doesn't mean we'll see LTO7 on POWER immediately. While
they will almost certainly support LTO7 the VAST Majority of IBM i
Customers don't even really need more than LTO4 for either capacity or
performance so this is really a fairly small market.

Hopefully that wasn't any violation of any NDA (non disclosure

agreement).

IBM hates it when people put off purchases waiting for the next big

thing.
