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.
