Re: SSD Performance Quesiton - How Much Faster that Spinning SAS

Rob, I saw in a PowerPoint that support for the UNIT(*SSD) parameter (for i 6.1) or UNIT(255) parameter (for i 5.4) with CRT commands requires fairly new group PTFS:
V5R4 - Database Group SF99504 Version 21
V6R1 â Database Group SF99601 Version 9 and 10

But I'd be more interested in some of the ASP balancing options where you'll let the operating system determine which hot objects belong on SSD.

I'm reading the same documents you are... I personally haven't seen SSDs in use yet. -Dan R.

Anyone see this option on the appropriate command?
DB2 and SSD Integration
This option allows a user to specify what data should be allocated on SSD. DB2 has provided the
capability to specify a âmedia preferenceâ as an attribute of a database table, partition, or index.
This option can be used on the CRTxx/CHGxx CL commands and/or the SQL statements used to
create or alter tables and indexes.
