. The E15k, along with other enterprise Sun servers, has the Dynamic Reconfiguration feature: administrators could dynamically change the assignment of RAM and processors to the different domains to meet changes in business needs. In addition, the 15K contains two system controllers (duplicated for redundancy), which are embedded SPARC computers running Solaris and used to manage the 15K and perform tasks such as booting and shutting down domains and assigning Uniboards to domains. The 15K contains minimal storage in itself (only system controller boot disks); it is connected via SAN to a separate

Sun Fire 12K

The Sun Fire 12K (codenamed ''Starkitty''), was a reduced configuration version of the 15K, introduced in April 2002. It supported a maximum of 52 processors, and was intended to fill a position in Sun's server product line between the 15K and the Sun Fire 6800.


Sun Fire E25K

The Sun Fire E25K (codenamed ''Amazon 25''; the "E" denoting "Enterprise") was announced in February 2004. Its base cabinet is identical to the 15K, with the only difference between the two systems being the processor boards installed. It reached end-of-life in January, 2009, and was superseded by the Sun SPARC Enterprise M9000 server. The E25K supports up to 72 dual-core UltraSPARC IV+ processors (up to 1.95 GHz). As with UltraSPARC IV-based 15K systems, the "MaxCPU" option was not offered for E25K systems. Overall system bandwidth is claimed as up to 172.8 GB/s aggregate, up to 115.2 GB/s peak, and up to 43.2 GB/s sustained. For overall I/O bandwidth, up to 35.8-GB/s sustained. Up to 64 GB of RAM per board is possible with a maximum of 1.15 TB of RAM for a single domain. Up to 72 hot swappable
