Big iron array vendor INFINIDAT has made its third major software release, adding compression, baked-in iSCSI support and enhanced array analytics.
The company’s architecture has 3 controller nodes, which each can see all the drives, and eschews an all-flash design, relying instead on up 1.2TB – 3.2TB of DRAM caching, 24TB to 210TB of NAND cache, and up to 480 x 7,200rpm disk drives. The system offers seven “nines” of uptime year – 99.99999 per cent availability.
There are now four Infinibox arrays in the range:
The entry-level F1000 arrived in August this year.
V3.0 of the InfiniBox software compresses data inline without impacting access performance. A data write arrives and is acknowledged in 180 microsecs. Then a background allocator function pulls the new data sectors and marshalls them for persistent storage on disk and the compression is done here so that data is compressed before it is written to disk. Currently the LZ4 algorithm is used but there will be a library of algorithms for different types of data so that compression improves over time.
Compression can be switched on or off, on a per-volume or filesystem basis, and the capability is part of a free OS upgrade to all supported InfiniBox customers, INFINIDAT will be guaranteeing a 2X compression ratio result. With compression, INFINIDAT says its arrays scale to over 5PB of usable storage capacity in a standard 42U rack.
