Engineering Parameters
| Chassis form factor | Controller enclosure: 2U rack mount Expansion enclosure: * DE240S: 2U rack mount |
|---|---|
| Controller Configuration | Dual active-active controller configuration with automatic load balancing. |
| RAID Level | RAID 0, 1, 3, 5, 6 and 10; Dynamic Disk Pools. * RAID 3 can be configured only through the Storage Manager Command Line (SMcli). * RAID 6, minimum six drives are required (five drives with one hot spare) for system functionality and data storage. |
| Memory And Cache | 32 GB per system (16 GB per controller). Cache mirroring between the controllers. Flash-backed cache protection (includes battery for destaging to flash). |
| Expansion The cabinet. Supports | * 4x DE240S (SAS SSD only) |
| Drive bays And Drive | * Up to 120 drives ( 24x NVMe drives in DE6400F controller enclosure + 96 SFF SSD hot-swap drive bays (4x DE240S SFF expansion enclosures). * DE240S SAS SSD only supported. |
| Backend Expansion Connection | * 8x 12 Gb SAS host ports (Mini-SAS HD, SFF-8644) (4 ports per controller) for expansion scale-up, daisy chaining of the expansion enclosures. * 2 x SAS expansion cards are required and must be installed in port1 only of the DE6400 enclosure controller. One in controller A, one in controller B. |
| Storage Capacity Supports | * Controller enclosure (367.2TB) + 4 x DE240S (1474.5TB) = 1841.5 TB * Scale up requires installation of a SAS expander card into slot 1 only |
| Storage Agreements | SAN (Block access): FC, iSCSI, iSER/IB, NVMe/FC, NVMe/IB, NVMe/RoCE, and SRP/IB. |
| Host Interface | A controller enclosure has two controllers. Supported HICs are: * 8x 10/25 Gb iSCSI SFP28 host ports (DAC or SW fiber optics, LC) (4 ports per controller) (1 port per controller, supported in bay 2/ port 2 only) * 8x 16/32 Gb FC SFP+ host ports (SW fiber optics, LC) (4 ports per controller) (1 port per controller, supported in bay 2/ port 2 only) * 2x 40/100 Gb NVMe/RoCE QSFP28 host ports (DAC cable or SW fiber optics, MPO) (1 port per controller, supported in bay 2/ port 2 only) Note: The controllers no longer offers base ports. Host connectivity is provided with a pair of HICs. |
