Dell EMC Unity 400 Hybrid

Dell EMC Unity 400 Hybrid

If you are looking for rich features and absolute simplicity in a small footprint, if you are cost-conscious and need the best from the best, Dell EMC Unity Hybrid Flash is for you. Designed for flash with rich data services, it delivers flash performance with the cost advantage of disk.

All Hybrid Models support 2 Drive Carrier types. The 12x3.5” and the 25x2.5”. Flash models only support the 25x2.5” model. Each unit has 2 Storage Processors (SP’s) in the rear with each 2 configurable ports and 2 Module slots that can hold up to 6 different modules.

The Dell EMC Unity hybrid models are the only ones to support FAST and FAST VP technology which helps with tiered storage and accessibility to high-frequency data.

12-drive DPE:
3.4” high x 17.5” wide x 27” deep (8.64 cm x 44.45 cm x 68.58 cm)
65 lb (29 kg)
25-drive DPE:
3.4” high x 17.5” wide x 24.17” deep (8.64 cm x 44.45 cm x 61.39 cm)
44 lb (20 kg)

Storage Processor (SP):
The Dell EMC Unity 300 has 2 Storage Processors.
Each SP comes with:

• Intel Xeon E5-2630 8-Core 2.4 GHz processor.
• 3 16GB DDR4 DIMM for a total of 48GB Per SP
• 2 embedded CNA ports (4 configurations possible)
• 2 10GbaseT ports
• 2 mini-HD SAS ports
• 2 PCI 3.0, x8 lane I/O module slots (6 Modules supported)

CNA Ports:
Each SP contains two integrated CNA ports (labeled 4 and 5). These ports are PCI Express 3.0 x4 adapters that provide interfaces that can be configured as Ethernet, or Fibre Channel, but once set to a protocol, cannot be changed. If CNA ports are set to Ethernet, you can use 1Gb/s, 10Gb/s SFPs, Twin-AX for File (IP), or iSCSI Block access. If the ports are set to Fibre Channel, then you can use SFPs supporting 4, 8, 16 Gb/s FC multi-mode, or single-mode SFPs supporting 16Gb/s only.

2 ports, configurable as either:

• 8/16 Gb Fibre Channel
• 4/8/16 Gb Fibre Channel
• 16 Gb Fibre Channel (single mode)
• 1/10 Gb IP/iSCSI

Note: The four CNA ports cannot be configured independently; they must all be configured with the same network protocol.

I/O Modules:
Each SP has two slots that can support 6 different options.

• Four-port 12-Gb/s SAS I/O module
• Four-port 16-Gb/s Fibre Channel I/O module
• Four-port 10-Gb/s optical I/O module
• Four-port 10GBASE-T I/O module
• Four-port 1GBASE-T I/O module
• Two-port 10Gb/s optical I/O module

Note: When adding new I/O modules, always install I/O modules in pairs—one module in SP A and one module in SP B. Both SPs must have the same type of I/O modules in the same slots. Please read the manual below for more details to each module listed above.

Standby Power Supply
12 DPE
AC 100 to 240 VAC ± 10%, single phase, 47 to 63 Hz
DC Line Voltage -39 to -72 V DC (Nominal -48V or -60V power systems)

25 DPE
AC 100 to 240 VAC ± 10%, single phase, 47 to 63 Hz
DC Line Voltage -39 to -72 V DC (Nominal -48V or -60V power systems)

Disk Array Enclosure (DAE)
The Dell EMC Unity 400 supports all three types of DAE’s with a max being either 15 DAE’s or 250 drives. When calculating the number of drives make sure to count the DPE drives as well in the total.

• 2U 25-drive DAE with 2.5-inch drives FLASH and SAS
• 3U 15-drive DAE with 3.5-inch drives FLASH, SAS and NL-SAS
• 3U 80-drive DAE with 2.5-inch drives FLASH and SAS

FAST Cache: A feature that allows Flash drives to be configured as a large-capacity secondary cache for the pools on the system. Only allowed in a Hybrid Dell EMC Unity.

FAST VP: Accelerates the performance of a specific storage pool by automatically moving data within that pool to the appropriate drive technology, based on data access patterns. For applications which are continuously active, consider configuring FAST VP relocations to run constantly.
