VMware says it has upped flash IO performance by half with the latest vSAN version, as well as adding myriad point feature updates.
The software is built to provide a virtual SAN by aggregating the locally-attached storage of a cluster of VMware host nodes into a shared block-access resource. It is the fundamental storage component in hyperconverged infrastructure (HCI) gear such as Dell EMC’s VxRail.
VMware claimed VSAN 6.6 has 50 per cent higher all-flash IOPS performance per host than the prior version - think 150,000 IOPS/host - which should help business-critical and next-generation workloads.
The next-generation workload improvements includes vSAN for Photon being available in Photon Platform 1.1 and a Docker Volume Driver delivering support for multi-tenancy, policy-based management, snapshots and clones.
VMware told us vSAN 6.6 has support for Intel 3D XPoint NVMe SSDs, and 1.6TB SSDs used as caching drives.
VSAN v6.6 adds:
- vSAN Encryption for data at rest – datastore level encryption in a dedupe/compression efficient way
- Local Protection for Stretched Clusters to avoid resync over the cluster connect if a node fails
- Unicast networking and removal of Multicast to simplify network deployment
- ESXi Host Client (HTML-5) management and monitoring functionality
- Enhanced rebalancing
- Enhanced repairs, with Resync traffic throttling
- Maintenance Pre-Check to alert you to host maintenance mode switchover impact
- Stretched Cluster Witness Replacement UI
- vSAN Cloud Analytics - vSAN included in “Phone Home / Customer Experience Improvement Program” including Cloud based health checks
- API enhancements
- vSAN Easy Install
- vSAN Config Assist / Firmware Update
- Enhanced Performance and Health Monitoring.
Previously encryption was done at a high-level before dedupe and compression were applied to data, and so rendered virtually ineffective. Now it works with them. Also VMware said vSAN encryption is hardware-agnostic and has simplified key management. It complies with 2-factor authentication (SecurID and CAC) and has a Defense Information Systems Agency-approved Security Technical Information Guide (STIG).
May 5 should see vSAN v6.6 availability, with list pricing starting at $2,495 per CPU, and vSAN for Desktop list prices starting at $50 per user. The vSAN Quality of Service capabilities are now available in all vSAN editions. The encryption and enhanced stretched cluster capabilities will only be available in vSAN Enterprise Edition. ®
