Storage array packs 3D NAND drives

Kaminario is not alone in offering flash at a cost that is competitive with spinning disk. In March, SanDisk announced it would target a new market that IDC has dubbed "big data flash" with its InfiniFlash storage system. One of the characteristics of this market is flash priced at under $1/GB, the analyst firm said. InfiniFlash does not use SSDs, however. Neither does Violin, which a month ago updated its product line to move downstream to make it appealing for enterprises to adopt as their primary storage rather than just for specific workloads.

The SanDisk InfiniFlash array packs 64 8TB SSDs to deliver 512TB flash storage in a rack-mounted system using eight 6Gb SAS interconnects.

The low price point for flash that Kaminario is offering is going to make increasingly hard to justify the use of hard disks, said Crump, but there's more at play here than just than just the low cost of flash. He said the flash storage market is at the point where customers don't really care what kind of flash is in an array, or how many writes it can handle. What they want to know is an AFA can do the job and how long it will last, said Crump, noting seven-year endurance guarantee. "If a storage system lasts me seven years, I'm pretty happy."

There are other features at play when customers evaluate an AFA, including the ability scale out and data services that they have come to expect from hard disk storage systems such as redundancy and replication, which has helped Kaminario. "All of that factors in," said Crump. "For most vendors, the missing link is data services."

According to research released at the beginning of the year by IDC, flash array adoption is growing at a rapid rate, and more flash-based platforms are delivering enterprise-class data services, including snapshots, clones, encryption, replication and quality of service as well as storage efficiency features. IDC said these features will be a competitive advantage for AFA vendors, as will the ability to offer mixed workload capabilities.
