This single processor SKU can adapt to the requirements of different workloads based on its runtime configuration. For example, the processor can be configured for transaction processing at a higher speed for one hour and then be switched to higher core counts for the next hour for higher throughput computing.
System Design
Sun Server X4-8 is a fully modular system, engineered to be easily serviceable. The eight sockets are connected through a passive midplane that maximizes availability and allows for maximum intersocket bandwidth. Sun Server X4-8 can be configured in either a four-socket or eight-socket configuration, with each socket attached to up to 24 DIMMs.
Each CPU module (CMOD) contains a single Intel Xeon E7-8895 v2 processor and 24 DIMM slots. The processor in each CMOD connects to a total of four memory buffers with six DIMM slots attached to each buffer. The CMODs are located just behind the front fans and are front-panel-accessible by removing the fans.
In the rear of the chassis is a single system module (SMOD) that houses the peripheral control hub functions, the Oracle ILOM service processor, and a PCIe slot for RAID storage HBA connectivity to drive bays. The SMOD also provides connectivity with one VGA, one management, one serial, two USB 2.0, and two GbE ports in the rear of the

The SMOD also provides connectivity with one VGA, one management, one serial, two USB 2.0, and two GbE ports in the rear of the chassis. Also in the rear are eight hot-swap-capable disk drive bays.
The dual PCIe card carriers (DPCCs) that hold standard low-profile PCIe cards are rear-accessible and, when inserted, sit directly behind a CMOD such that each of the eight CMODs corresponds to one of the eight DPCC modules, respectively.
