ESS 2105-800 DS6800 comparison

[Nigel Salway]

I am looking at migrating from an ESS 2105-800 shark to a used DS6800 1750-522.

I am curious to learn if anyone has done a similar conversion and can comment on the relative performance of the two storage subsystems. The IBM redbook SG24-6781-02 says the DS6800 will out-perform the 2105-800 shark in most zOS implementations.

I am also interested in hearing from someone who has installed a used DS6800 and if they had any issues installing and setting up the DS Storage Manager software.

Nigel,

I can't comment about the ESS-6800 comparison, but the 6800 is a speedy
little box. We put ours in new and subsequently added another shelf
after the fact. If you're careful about the logical disk layout you
shouldn't have any problems.

The only got'cha I can offer is to check the firmware level of the box.
IBM has specific instructions on upgrading, as far as what levels can be
migrated to/from. Follow their recommendations! I know most of us have
done z/OS upgrades outside of the IBM recommended levels and gotten away
with it. These firmware upgrades aren't as forgiving. Also, if you
need to do a level A-B-C upgrade to get current, don't do them
back-to-back. I tried that and have the scars (although no t-shirt...).
The upgrade hung halfway through the second part and I couldn't move
forward or backward. IBM level 2 support finally got me going again and
they chastised me for trying to do 2 upgrades essentially at the same
time. They told me that I should have done the A-B upgrade, let the box
sit for a few days to a week, then done the B-C upgrade.

One other nit-picky thing that possibly could bite you if the seller
pulled the GBICs - make sure you get them back in the right locations!
It uses long-wave for the connection to the Z and short-wave to go
between the enclosures. The GBICs are not very well marked (dark blue
versus blackbands on the handles) and when we put ours in there was no
documentation telling us that. We managed to get all 4 of the longwave
GBICs misplaced and the Z couldn't see the 6800. Had both me and my CE
scratching our heads for a while until I figured that one out.

Are you aware that IBM has announced that the DS6000 line will be withdrawn from marketing this summer?

talking about withdrawn, IBM had done long time ago for ESS 750/800.

Nigel,

Converted from a Hitachi unit emulating a ESS 2105 to a DS6800 using
FDRPAS and FLASHCOPY in 1 day, (10 TB), It was awhile back but there
were no problems or issues. Except it didn't support Flashcopy 2 at the
time (Dataset level)

Since the DS6800 was rack mounted, I should have opted for the in rack
LAPTOP, Instead of table to support my monitor and keyboard only.

Oh yea. We went from ESCOM to FICON...so great for performance.

Kevin

Kevin,



Thanks for your feedback.



In my case, we are already running FICON with the Shark, so we shouldn't see a change in performance there.



Is the in-rack laptop a feature be ordered with the DS6800, or is it a matter of buying any compatible laptop and rack mounting it? Can you clarify?



I will check on Flashcopy 2 availability, although we only use flashcopy at the volume level.



Sincerely,



Nigel Salway

The console for the DS6800 is IBM part number 425242J that you should order at the same time.

You also need to order Windows Server (2008R2 according to my last IBM notice) to run the console and its application.

Flashcopy on DS6800 is nothing like as efficient as on Shark.

Hi Nigel,

Since you had beening using ESS 2105-800, recently we're going to replace
2105-F20 with 2105-800. Are you aware any published performance data for
2105-800? I have been no luck in IBM PRODUCT page.

Cobe,

The best documentation on 2105-800 performance I found was the redbook
SG24-6422-00.
