Supermicro is expanding its product line with a new family of E3.S storage solutions. The models presented support both PCIe Gen5 drives and CXL memory modules (CMM). The use of up to four E3.S-2T-CMM (15 mm) enables cache coherence between CPU memory and DDR-based memory modules connected via PCIe.

The E3.S standard allows a storage density of up to 256 TB in a 1 U or half a petabyte in a 2 U housing. A standard rack can therefore hold a storage capacity of more than 20 petabytes. A connection via NVMe-oF (NVMe over Fabrics) ensures high data throughput. The new series includes the models SSG-121E-NE316R, SSG-221E-NE324R, ASG-1115S-NE316R and ASG-2115S-NE332R. The 1U servers accommodate up to 16 hot-swappable E3.S drives or eight E3.S and four E3.S 2T CMM drawers. In the 2U models, on the other hand, up to 32 hot-swappable E3.S drives can be installed in single and dual CPU configurations. For the installed CPUs, Supermicro uses either Intel Xeon Scalable processors or fourth-generation AMD Epyc models.
The manufacturer states that the special symmetrical architecture ensures particularly short signal paths for data and at the same time reduces latencies. In addition, the special design should enable an improvement in the internal airflow, which contributes to improved drive cooling. Supermicro has not yet provided any information on the availability of the new E3.S storage solutions.
