Quad-Socket Xeon Server for Compute-Intensive

The Supermicro SYS-8048B-TRFT is a 4U rackmount system built around four Intel Xeon E7-4890 v2 processors. Each CPU runs at 2.8 GHz with 15 cores and reaches 3.4 GHz under turbo. The platform delivers 60 total cores for virtualisation, database or high-performance computing tasks that demand dense multi-threaded throughput.

Redundant Platinum Power and Front-Access Cooling

Four 1620 Watt Platinum-efficiency power supplies provide full N+N redundancy with hot-swap replacement. The chassis uses 24 front-accessible 3.5-inch drive bays that direct airflow across installed drives and the CPU complex. IPMI 2.0 with a dedicated RJ45 management port enables remote power control and sensor monitoring without loading the operating system.

MegaRAID Controller and Dual 10GBase-T Networking

An LSI MegaRAID 9361-8i card with 1 GB battery-backed cache manages RAID 0, 1, 5, 6, 10, 50 and 60 across the SAS and SATA backplane. A SuperMicro AOC-STG-i2T add-in card adds two RJ45 10GBase-T ports based on the Intel X540 controller. The system ships with 24 drive trays but no hard drives, front bezel or rack rails included.

Questions about this item

How do I install the four Xeon E7-4890 v2 processors into the LGA 2011 sockets, and what step is often missed?

Align each processor with the socket notches, lower the load plate, and secure the lever; the step often missed is applying thermal compound before mounting the heatsinks.

Which components will need replacement first during long-term operation?

The 1620 Watt Platinum power supplies and system fans are the primary field-replaceable units; the MegaRAID 9361-8i cache battery will also require periodic replacement.

What thermal or power limit appears first when all four CPUs run at 3.4 GHz turbo under sustained load?

The 1620 Watt power supply capacity and chassis cooling design set the practical ceiling before the processors reach their maximum turbo frequency continuously.
