Key features and benefits
DDR5 memory platform
The system includes 16 GB UDIMM DDR5 and supports a maximum capacity of 192 GB; optional ECC memory is supported.
Dual M.2 PCIe Gen 5 slots
Install compatible M.2 NVMe SSDs for cache acceleration, with support stated for PCIe Gen 3 and above.
Three PCIe Gen 4 slots
Add supported network, SAS storage-expansion or Fibre Channel cards as requirements develop.
Built-in 2.5GbE connectivity
Two 2.5GbE Ethernet ports provide multi-gigabit connectivity over compatible network infrastructure.
Large storage expansion path
Connect up to eight 24-bay JBODs for a stated maximum of 204 disks.
Redundant power design
Two 550W power supply units support continuity-focused rack deployments.
Who is this model best for?
A strong choice for
- Tier 2 storage and backup infrastructure
- Virtualisation storage
- Collaborative 4K video-editing workflows
- Rack deployments planning substantial JBOD expansion
- Organisations seeking DDR5 memory and M.2 Gen 5 expansion
Consider another model if you need
- You need an all-flash U.2 NVMe platform rather than SATA drive bays
- You require more than 16 GB memory installed from day one
- You need a tower system rather than a 2U rackmount chassis
