Dual-socket 1U server for dense compute

The SYS-6018U-TR4T+ fits two Xeon E5-2695 v4 processors into a single rack unit, delivering 36 total cores at 2.1 GHz with 3.3 GHz turbo. It targets workloads that need high thread counts in limited rack space, such as virtualization hosts, HPC nodes, or cloud infrastructure tiers.

MegaRAID 9361-8i and quad 10GBase-T change storage

The bundled 12 Gb/s RAID controller with 1 GB cache and battery enables RAID 0, 1, 5, 6, 10, 50, 60 across four hot-plug 3.5-inch bays. The AOC-UR-i4XT add-on card provides four RJ45 10GBase-T ports, removing the need for a separate NIC in top-of-rack deployments.

512 GB DDR4 2400 MHz registered ECC decides memory

Sixteen 32 GB modules populate the 24 DIMM slots, leaving eight slots open for future expansion up to 1.5 TB. Buyers who need more memory headroom can add modules; buyers who need less should verify the cost of populating fewer slots.

Questions about this item

How long will the MegaRAID 9361-8i controller battery last before replacement?

The MegaRAID 9361-8i includes a 1GB cache with battery backup; typical battery life spans several years under continuous operation, after which the module can be swapped without removing the controller.

Which component reaches its thermal limit first when both Xeon E5-2695 v4 CPUs run at 3.3GHz turbo continuously?

The 1U chassis relies on high-speed internal fans to cool the dual 18-core processors and 750W power supplies; sustained turbo loads push CPU package temperatures toward their maximum rated threshold before other components.

How loud are the fans when the server runs 24/7 with both 750W PSUs active?

Dual 750W Platinum supplies and dual 18-core Xeons require high-RPM cooling in a 1U form factor, producing noticeable airflow noise typical of dense rackmount systems under constant load.
