Nexenta adds object storage NexentaEdge and all-flash array NexentaStor

Nexenta has announced a new massively scalable, scale-out block and object software-defined storage product, as well as upgrades to its NexentaStor block and file product and NexentaConnect virtual desktop infrastructure (VDI) system.

NexentaEdge is the company’s new block, file and object storage software-defined storage product. Unlike NexentaStor, it is a scale-out product that can scale to hundreds of petabytes and is aimed at service providers and those building big data repositories.

NexentaEdge is similar to the existing NexentaStor product insofar as it is a software-defined storage product that allows customers to build storage environments from commodity hardware. Unlike NexentaStor, however, NexentaEdge has object access (OpenStack Swift and S3 Object APIs), block access (iSCSI and OpenStack Cinder), huge scalability and scale-out characteristics.

The key change allowing these is the creation of a new operating system, said Mike Letschin, director of product management at Nexenta.

“NexentaStor is firmly rooted in ZFS, and is limited to a few petabytes and to two or four-node clusters, with two nodes in Nexenta," he said. "But NexentaEdge is in-house written, and has some of the DNA of ZFS, but is enhanced to allow massive scale-out scalability to hundreds of petabytes.”

Meanwhile, NexentaStor – the company’s block and file-based storage software – has been upgraded to version 4.1, in a move that sees the product re-engineered to support the creation of all-flash arrays from commodity x86 hardware with SanDisk or Western Digital flash drives up to 150TB.

The key changes, said Letschin, comprise, “tuning the solution to decrease latency across the SAS backplane” to get “performance comparable to an all-flash appliance”.

The NexentaStor upgrade has also seen the addition of VMware integration features, namely a vCenter Management Plugin and VAAI (VMware APIs for array integration).

NexentaConnect, the company’s VDI storage product, sees enhancements that include version 3.0 for VMware Horizon, which will see the product updated to keep pace with Horizon upgrades, in particular to version 6.

Also added is NexentaConnect for VMware Virtual SAN. This will enable NexentaConnect to create NAS file-based connectivity into a VMware VSAN environment with SMB and NFS access.
