Fujitsu ETERNUS DX500 S4 Key features


The Fujitsu ETERNUS DX500 S4 supports both 2.5" HDD/SSD and 3.5" HDD SAS 3.0 12Gb/s.  The ETERNUS DX500 S4 has a high expansion potential as up to 10 drive shelves can be hooked together using the controller’s SAS ports. LFF and SFF shelves can be mixed together with the only limitation being a 528 maximum drive count with a maximum storage capacity using HDD of 6,336TB / SSD of 8,110TB.  Choice is another key feature as the ETERNUS DX500 S4 chassis is available with 12 LFF or 24 SFF drive bays plus single or dual RAID controllers and supports an impressive selection of host interfaces. For the latter, Fujitsu offers Fibre Channel (32Gbit/s, 16Gbit/s, 8Gbit/s), iSCSI (10 Gbit/s [10GBase-SR, 10GBase-CR, 10GBase-T], 1 Gbit/s), Ethernet (10 Gbit/s, 1 Gbit/s), SAS (12Gbit/s).

The controller’s internal drive interfaces support 12Gbps SAS support and drive options are equally good as Fujitsu offers SSDs, near-line SAS and SAS models in a range of capacities. Controller processing power has been improved while their base system memory supports 256GB.

For redundancy the dual controllers function in active/active mode, all drives bays are hot-swappable and the array sports dual hot-plug power supplies. Additional expansion shelves are daisy-chained using the external SAS ports on both controller for fault-tolerant links.

The Fujitsu ETERNUS DX500 S4 is also a unified storage solution as it can support NAS operations. However, there are some provisos which need to be considered first.  The array supports CIFS and NFS but NAS support must be ordered at the point of sales as you can’t upgrade existing SAN only models. The combined SAN/NAS firmware requires controllers with a minimum of 8GB and they use a different type of channel adapter for the data ports as well.
