AB548A is an Intel Itanium 2 1.6-GHz dual processor module with 6 MB of cache, for the HP Integrity rx7620 and the HP Integrity rx8620. HP calls it the rx7620/rx8620 Itanium 2 1.6GHz 6MB 2-pack CPU, and two processors come on the module. It replaces the two processors of an older module when a server is upgraded.
The 1.6-GHz processor carries 6 MB of level 3 cache, 256 KB of level 2 cache and 32 KB of level 1 cache, with single-bit cache error correction, 44-bit physical addressing and 64-bit virtual addressing. AB548-69102 is the spare processor: an Intel Itanium 2 at 1.6GHz with a 400MHz front side bus and 6.0MB level-3 cache. A6913-69215 is a cell board that includes four 1.6GHz, 6.0MB cache processors. The Instant Capacity version is AB550A.
A 1.6-GHz processor consists of two chips, so it can only be ordered or upgraded in pairs. A cell board needs at least two active processors, and processors go onto the board in the sequence 0, 2, 1, 3. The 1.6-GHz and 1.5-GHz speeds can share a chassis, with one speed per cell or hard partition.
The rx7620 and rx8620 need system firmware version 3.30 or later for Itanium 2 processors that ship after June 15th, 2005, including AB548A; OpenVMS needs version 4.0. The MP sysrev command reports the installed firmware version.
