Flash storage specialist Pure Storage has unveiled the sixth iteration of its in-house OS Purity. Several additions are in the program such as an extension of disaster recovery functions, better management of Optane memories. Note also the integration of file mode to have a unified view of the storage.
And 6. Pure Storage, almost like a metronome, follows its schedule of OS updates from its flash arrays. Purity 6 has indeed just seen the light of day with its share of developments and contributions. Gabriel Ferreira, technical director at Pure Storage France, reveals the major axes to us. “First, there is a focus on disaster recovery with Active DR. This is a replication method that lies between synchronous (active / active) and asynchronous replication ”, specifies the person in charge. “There is a real-time, continuous, active / passive replication with fast RTO / RPO. The idea is to move closer to synchronous replication, ”he adds. Without the need for additional hardware, this functionality integrates with solutions like VMware Site Recovery Manager and Microsoft SQL, Oracle, SAP and MongoDB databases.
Another focus of the pure player is on the unification of storage resources. For this, it offers FA Files. “Our customers need to have a NAS service alongside, especially for file sharing,” notes Gabriel Ferreira. To manage file mode, Pure Storage acquired the company Compuverde in 2019. Working in VMware and Microsoft environments, the start-up offers vNAS, a scalable NAS software supporting hyperconverged platforms and providing native hybrid cloud support, thus meeting the needs of businesses. “We have integrated the vNAS offer into Purity and now customers can manage file systems from their arrays at the same level as the block,” observes the manager. The unified platform thus benefits from all the functions such as RAID at the level of clustering, deduplication / compression, snapshots, etc.
An extension of NVMe-Roce and reinforcement on Optane
In the Purity 6 catalog, we note the extension of support for NVME over RoCE (RDMA on Converged Ethernet). “This is not something new because the protocol has been supported since 2018. But VMware and Cisco through the UCS have published their design for this technology,” said Gabriel Ferreira. This will allow customers to have an end-to-end solution based on NVMe over Fabric and have faster communication between storage and servers.
Finally, the focus is also on the arrival of Optane memories from Intel in the bays to play the role of cache. “Customers really appreciate this technology, but want more capacity,” admits the technical director. Pure Storage has therefore optimized the DirectMemory Cache function within Purity and by offering two additional bundles comprising capacities of 3 TB and 6 TB on 750 GB modules.
