Information in this document applies to any platform.
Sun Storage 2500 Arrays (2510, 2530, 2540, but not 2530-M2 or 2540-M2) have been shipped over time with either 512MB or 1GB of controller cache memory. Customers with 512MB memory have had the option to upgrade memory in the field to 1GB. This upgrade did not change the part number originally assigned to the 512MB controller. In the event that a 512MB controller upgraded to 1GB in the field needs to be replaced, it is important that the replacement controller be the 1GB version, thus requiring a different part number for the replacement.
This applies only to those arrays where a cache upgrade has been done using marketing option XTA-2500-1GBMEM. For any other controller-related issues, please reference <Document 1021113.1> Sun Storage 2500, 2500-M2, 6000 and Flexline Arrays: Troubleshooting RAID Controller Failures.
This article discusses the details of how to determine on-board memory, and how to identify the correct replacement part number.
