About this item

#1: Dual active-active controllers

Dual active-active controllers provide supreme uptime and redundancy to ensure high availability.

#2: NVRAM module

NVRAM reduces the risk of losing write cache data if unexpected power failure occurs.

#3: QES operating system

Supports ZFS near-limitless snapshots, SnapSync, block-level data deduplication, and inline data compression.

#4: Storage for virtualization

Supports VMware vSphere, Windows Server and Citrix XenServer for storage virtualization.

#5: 10GbE SFP+ ports

Four 10GbE SFP+ ports (per controller) accelerate virtualization, large file sharing, and intensive data transfer.

#6: PCIe Gen 3 slots

Two PCIe slots (per controller) allow for adding 10GbE/25GbE networking cards to increase application performance.
