Hardware Rqmts for Upgrade 4.6C to ECC 6.0

[Former Member]

We are replacing hardware and need round estimates of % increase to be expected for DASD, MEMORY, and PROCESSOR after upgrade from 4.6C ASCII to ECC 6.0 Unicode.

I thought I saw a thread on that in this forum but cannot find.

TIA,

Hello Margie,

for non-unicode you would need:

CPU: 10 - 33 %

Disk: 10 - 30 %

Memory: 45 - 66 %

And for unicode additionally 30% CPU, 50% RAM and Disk 10-20%:

This would mean totally:

CPU: 43 - 73%

Disk: 10 - 53 %

Memory: 116 - 150 %

But this are only figures for the current situation. You should take into account the DB-growth and further changes...

Those values are only estimated, it depends on your usage type. Hope it helps.

I am surprised.

I though the ASCII implementation (on this platform) was an almost-Unicode implementation (as opposed to plain ASCII one character = one byte), hence I expected only a small increase when converting from this almost-Unicode to "full Unicode".

Hi Peter,

> And for unicode additionally 30% CPU, 50% RAM and Disk 10-20%:

The first 2 are the official SAP figures for all platforms. The third is for iSeries. My experience, is for the third: 5-10%

The first 2:

CPU: +20-25% (as the DB server was on Unicode before already)

Memory: +25% (or less, as the most part of memory is used in the DB is this is on Unicode already)

but especially the CPU point is still true and pretty high with about 25%, because most of the CPU is taken in the appl server and that was pure ascii before.
