Ultrastar Serv24-HA

Ultrastar Serv24-HA

Combining the speed of NVMe™ SSDs with a dual-server architecture, the Ultrastar Serv24-HA delivers a “cluster-in-a-box” for Software-Defined (SDS) storage.



High Performance– Up to 24 NVMe dual-port SSDs with a range of capacity and endurance options

High Availability– Dual high-performance Intel Xeon Scalable Processor-based server canisters

High Capacity–Up to 184TB in 2U

Newly available dual-port NVMe SSD technology means that all-flash array deployments can now benefit from full high availability and NVMe performance. The servers are connected with a Non-Transparent Bridge (NTB), a PCIe Gen3x16 link, which the software-defined storage stack can use to synchronize metadata between the two compute canisters.

Designed for Fast Data

The Ultrastar Serv24-HA is built to deliver high availability and enterprise-class reliability. The entire enclosure, including server canisters, is backed with a 5-year limited warranty.
