Dual active-active controllers
Dual active-active controllers provide supreme uptime and redundancy to ensure high availability.
NVRAM module
NVRAM reduces the risk of losing write cache data if unexpected power failure occurs.
QES operating system
Supports ZFS near-limitless snapshots, SnapSync, block-level data deduplication, and inline data compression.
Storage for virtualization
Supports VMware® vSphere®, Windows Server® and Citrix® XenServer® for storage virtualization.
10GbE SFP+ ports
Four 10GbE SFP+ ports (per controller) accelerate virtualization, large file sharing, and intensive data transfer.
PCIe Gen 3 slots
Two PCIe slots (per controller) allow for adding 10GbE/25GbE networking cards to increase application performance.
