Hardware configuration
The 
D-rack provides cloud units, a measure of cloud capacity. Three types of cloud units are offered:
- Compute units – provide raw compute capacity and are defined similarly to compute units of Amazon AWS.
- Caching units – provide high-performance SSD caching.
- Storage units – provide persistent storage on a storage back-end
This raw cloud capacity is delivered through one or multiple D-racks. Customers only pay for raw cloud capacity and D-racks are delivered with all components to make the solution work end-to-end, including networking, power monitoring and management software. There are no hidden costs!
A typical D-rack configuration includes:
- 24 compute nodes
- 10 storage nodes
- 8 caching nodes
- 3 management nodes - for redundant cloud management SW
- 5 Ethernet switches
- Power management
This configuration provides the following cloud capacity
- 1536 compute units w/ 1.7 GB RAM each
- 120 storage units, equivalent to 120TB net end-user storage
- 7680 caching units, equivalent to 7.68 TB of SSD
For example, this capacity allows 50 SME’s to run 20 virtual desktops and 5 medium sized servers.
