The IBM eServer pSeries 660 Model 6M1 is a mid-range member of the 64-bit family of symmetric multiprocessing (SMP) enterprise servers from IBM. Positioned between the Model 6H1 and the powerful Model S85, the Model 6M1 provides the power, capacity, and expandability required for e-business mission-critical computing. The Model 6M1 can assist you in managing the evolution of your business to incorporate the power of the Web and 64-bit computing into your environment while still supporting existing 32-bit applications.

The Model 6M1 delivers a cost-efficient growth path to the future including optional processor Capacity Upgrade on Demand. It provides 64-bit scalability via the 64-bit RS64 IV processor packaged as 2-way and 4-way cards. With its two-processor positions, the Model 6M1 can be configured into 2-, 4-, 6-, or 8-way SMP configurations. The Model 6M1 also incorporates an I/O subsystem supporting 32-bit and 64-bit standard PCI adapters. The Model 6M1 has 2-and 4-way processor cards that operate at 750 MHz and incorporate 8 MB of L2 cache per processor.
