Re: Domino saves: 3582 attached via fiber blows the doors off of

We really blow doors off of backups  with the new 3492 tape drives. We 
just went from the 3590 to the new 3492. Transfer rate went from 14/mb per 
sec to 60 mb/per sec max. We are getting a transfer rate of around 180 GB 
per hour to our new 3492 tape drives on a brand new 3494 Enterprise Tape 
Library using BRMS! 

Really fast over GB fiber and tape compression is working well too, we fit 
our whole system on 1 tape. Approx 640 GB.  Tapes are 300GB uncompressed 
and 900 GB at 3:1 compression. 

I was able to perform a full system save in less time, transfer rate was 
around 250 GB per hour with everything in restricted mode doing a Option 
21 save. 
 
Fast Fast Fast!!!!!!!!!

subject: Domino saves: 3582 attached via fiber blows the doors off of
                 3590E attached via 2749 card

Thought I double post these findings to the domino list.

Our Domino backup used to run on a 3590E attached via 2749 to our 840. Now 

it runs on a 3582 fiber attached to a 5704.
The time went from 4 tapes running  between 18:45-23:02 to 1 tape running 
between 21:00 to 22:54.

Our DB2 backup used to run on a 3590E attached via 2749 to our 840.  Now 
it runs on a 3582 fiber attached to a 5704.
The time went from 1 tape running from 00:16-05:00 to 1 tape running from 
00:01-03:51.

Our TSM backup (which saves huge individual objects using SAVOBJ in one 
library) used to run on TWO 3581's attached via 2749, reading the object 
names individually off of a data queue from two separate backup jobs (one 
for each tape drive) from our 840.  Now it runs on ONE 3582 fiber attached 

via 5704.
The time went from 10-12 tapes running from 22:00-08:14 to 5 tapes running 

from 22:00-06:58.

Our 270 used to used to use a 25GB cartridge to save itself.  Now it runs 
on a 3580 attached via 2749 card.  That save used to run on 1 tape from 
00:01-01:46.  Now it runs from 00:01-00:46.

In summary,  the 3582 fiber attached via 5704 blows the doors off of the 
3590E attached via 2749.
And the 3582 fiber attached via 5704 blows the doors off of the 3581 
attached via 2749.
And the older 3581 attached via 2749 card blows the doors off of the 25GB 
cartridge.
Soon as we finish duping tapes from our 3590E to the 3582, and get that 
new hardware for our 820, the 3590's are out the door.

and...

We also replaced a 3590E attached via a 2749 on a 270-2454 with a 3582 
attached via fiber to a 5704.
The 'complete' save went from 5 tapes in 4 hours and 10 minutes to 1 tape 
in 2 hours 39 minutes.
A vast majority of the disk is used up by Domino data.  Something about 
saving Domino data really shines on these 3582's versus the 3590E's.

I had a pmr open as to why the Domino saves varied so widely on our 3590E. 

 Sent some performance data off to IBM, but never heard a response.
