Quad-socket server for enterprise workloads

The Supermicro SYS-8048B-TRFT is a 4U rackmount system built for compute-intensive and storage-heavy applications. It ships with four Intel Xeon E7-4890 v2 processors running at 2.8 GHz with 15 cores each. The platform includes 2 TB of DDR3 1600 MHz registered ECC memory across 64 DIMM slots. This configuration targets organisations running large databases, virtualisation clusters or high-performance computing tasks.

24 hot-swap 3.5-inch drive bays define storage

The chassis provides 24 front-accessible bays that accept SATA or SAS hard drives for massive raw capacity. A MegaRAID 9361-8i controller with 1 GB cache and battery backup supports RAID 0, 1, 5, 6, 10, 50 and 60. No drives are included, so buyers must supply their own disks. The 8-port controller limits the number of direct SAS connections to eight devices without additional expanders.

Tool-less trays simplify drive installation

Drive trays slide into the front bays without screws, and the four 1620 W platinum power supplies are hot-swap redundant. IPMI 2.0 with a dedicated RJ45 port gives KVM-over-LAN and virtual media access for remote management. The front bezel and rack rails are not included, so they must be sourced separately. The 1U height listed in the spec sheet conflicts with the 4U form factor, so verify rack space before ordering.

Questions about this item

What does the 2.8 GHz clock on the four Xeon E7-4890 v2 processors mean for real-world throughput?

Four 15-core Xeon E7-4890 v2 CPUs at 2.8 GHz provide 60 physical cores and can turbo to 3.4 GHz, giving heavy multi-threaded workloads a large, consistent compute pool.

How does the LSI MegaRAID 9361-8i controller limit the 24 drive bays in practice?

The 9361-8i is an 8-port SAS 12 Gb/s RAID card, so only eight drives connect directly to hardware RAID; the remaining bays need an expander or additional controller.

What mounting hardware must be sourced separately to install this 4U chassis in a rack?

The supplier notes that front bezel and rack-mount rails are not included, so you must provide compatible rails and a bezel for a standard 4U rack opening.
