Notes
- The 6215 and 6219 adapters appear to be essentially identical other
than the fact that the 6215 is PCI and the 6219 is MCA (they both take
the same microcode and appear to have identical functionality).
- Availability of TMSSA support may depend on what version of microcode
is on the adapter (the 6215 and 6219 adapters require at least level
1801).
- The Name column is intended to show the name as reported by
lscfg.
- If a second name appears in the Name column then that name
is an alternative name frequently used in the IBM SSA documentation.
- The Advanced SerialRAID Adapters (6225 and 6230) are capable of 40MB/sec
per direction per loop. The other adapters are capable of 20MB/sec
per direction per loop.
- Many of the values in the above table assume that the adapter has
sufficiently current microcode.
- The Advanced
SerialRAID Plus Adapter Planning Guide states:
The Advanced SerialRAID Plus Adapter has code above level
7600. The Advanced SerialRAID Adapter had code below 7600 and that adapter
can be converted to support the additional functions by downloading code
above level 7600.
i.e. the adapters are identical if they have sufficiently recent microcode.
This would seem to explain why the 6225 and the 6230 both are type 4-P.
- We don't have access to all of these adapters. Consequently, there
are bound to be errors in the table. Please provide us with corrections
if you notice an error.
IMPORTANT: If you lack the appropriate skills, experience and/or
competency, are unwilling to take responsibility for your actions,
or if you don't like these disclaimers then
