The scalable and unified Fujitsu ETERNUS DX100 S4 delivers enterprise-class functionality to small and medium-sized companies and subsidiaries with an excellent price/performance ratio. It is the perfect solution when consolidating data for server virtualization, e-mail, databases and business applications as well as centralised file services. Simple, intuitive system management, highly flexible network connectivity and the option of field upgrades to higher system classes significantly reduce operational and migration costs. The Fujitsu ETERNUS DX100 S4 architecture lets customers benefit from software options, such as thin provisioning, automatic storage tiering and quality of service management even as early as the entry-level class. This all contributes to better business support.
The Fujitsu ETERNUS DX100 S4 supports both 2.5" HDD/SSD and 3.5" HDD SAS 3.0 12Gb/s. The ETERNUS DX100 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 144 maximum drive count with a maximum storage capacity using HDD of 1,728TB / SSD of 2,212TB. Choice is another key feature as the ETERNUS DX100 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 32GB.
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 DX100 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.
