Key features and benefits
Short-depth 2U chassis
The 297.4mm depth suits small media cabinets and rack spaces where cabling or installation depth is constrained.
Dual 2.5GbE
The supplied content states that port trunking across the two built-in 2.5GbE ports can deliver up to 5Gbps.
PCIe network expansion
The PCIe Gen 3 x2 slot supports supplied options including 2.5/5/10GbE adapters, QM2 cards and USB 3.2 Gen 2 cards.
HDMI media output
The supplied feature set includes HDMI 1.4b output, 4K media playback and real-time transcoding.
Backup and recovery apps
The existing description lists protection for PCs, Macs, virtual machines, containers, cloud data and SaaS services.
QTS or QuTS hero path
QTS is the default operating system, with switching to QuTS hero supplied from QTS 5.2.2 for ZFS data integrity and WORM technology.
Who is this model best for?
A strong choice for
- Businesses needing eight rackmount drive bays
- Short-depth rack or media-cabinet installations
- Shared storage using two built-in 2.5GbE ports
- Backup, recovery and hybrid-cloud workflows described in the supplied content
- Deployments that may later add optional 5GbE or 10GbE networking
Consider another model if you need
