xMII server specifications

[Former Member]

Hello all,

SAP recommends the following specifications for the xMII server

1) RAID - 1 Disk (3 logical SATA Disks)

Question: Our normal standard is for a RAID 5 with three physical drives. Would this cause any issues?

On the 3 logical SATA Disks, does this mean 3 logical volumes are required?

2) Database size - 400 GB

Question: Is this the recommended capacity of the RAID set or is it the recommended size of just the database? We plan to do a small POC and this strikes me as being overkill. Is this quantity correct?

Any help would be appreciated.

Hi

Check the system requirement from

Jawahar - Please watch your versions. This is the second forum post that you have included this hyperlink to an old SDN document that was for version 11.5, not version 12.0. Even though the application content and connectivity is largely the same the entire web application server and underlying architecture has been ported from a file system based Microsoft IIS / NewAtlanta ServletExec to the database system running on NetWeaver WebAS 2004s SP10+. The specs listed in Joe's document are quite outdated.

Srinivasan - the application content and complexity that you implement and the number of users accessing the system should still be your guide for any sort of sizing. Since xMII version 12.0 is now an application deployed onto the WebAS Java stack you should use the NetWeaver sizing tool for the hardware recommendations and then include RAM allocations and possible clustering considerations that are in alignment with your prospective xMII 12.0 application.

Hi Srinivasan,

is this for version 11.5 or 12? Version 11.5 certainly does not require 400GB of disk space but has an installed footprint closer to 250MB.

Also, your RAID configuration shouldn't matter as that would be transparent to the operating system and any applications running on it.

Those requirements are for 12.0, most likely, and are definitely on the "high side" of real requirements. You should be fine with much less disk storage. What I would not shortcut, however, is the amount of RAM for 12.0.

As a matter of interesting history, the very first version of Lighthammer Illuminator (the precursor to xMII) fit on a 1.44 MB floppy disk, installed in 15 seconds, and required about 8MB of RAM...

Programmers are getting lazy.
