Fault Tolerance
Fault tolerance is good as this 4U Supermicro based system has two 1200W hot-plug power supplies and the Open-E software is installed on a mirrored pair of Kingston 8GB SSDs. Broadberry advised us it chose these as they have a much higher MTBF than the USB sticks you commonly see Open-E deployed on.
The appliance's quad Gigabit ports can be placed in fault tolerant or load balanced teams and you have support for MPIO (multi-path I/O) as well. Three spare PCI-e slots are up for grabs and Broadberry offers a selection of Intel Gigabit and dual-port 10-Gigabit cards.
The appliance was supplied with six 3TB Seagate SAS 2 drives preconfigured in a RAID-6 array. Broadberry charges 299 for each extra 3TB SAS 2 drive and it expects to have 4TB drives certified soon.
The management web interface is easy enough to use and you start by creating volumes. Each RAID array is classed as a volume group and within these you create logical volumes and decide whether they are for NAS, IP SAN or, with an appropriate HBA installed, FC SAN usage.
iSCSI targets are assigned a LUN and you can use CHAP authentication for host access control
