Ask an IBM representative for specifics.** Processor detail: Processor quantity and model, cores, core speed, L3 cache, memory speed, and TDP.¤ This model includes the DIMMs that are rated at 1600 MHz, but operate at up to 1333 MHz, as noted, to match theprocessor memory speed* Models A7x and A8x include IBM FlashCache Storage Accelerator for Direct v2.x; model A9x includes IBMFlashCache Storage Accelerator for Virtual v2.x. All models include 3 years service and support‡ Model B3x includes the Broadcom NetXtreme II ML2 Dual Port 10GbE SFP+ adapter (BCM57810S based). Allother models include Intel I350-T4 ML2 Quad Port GbE Adapter adapter (I350-AM4 based).§ Models with six slots have the Primary I/O Book (four slots) and Storage Book (two slots) standard. Models withnine slots also include one Half-length I/O Book.
