Besides bumping their virtualization-platform to version 6.5, VMware also added some new features to the SDS-solution in the new version of VSAN it announced. This quick article talks about the main new features which stood out according to us.
VSAN Version History
To give a idea what the main new features were in the previous releases of VSAN here, a short overview:
| Version | Timeframe | Added features |
| VSAN (1.0) 5.5 | March 2014 | Inital Version |
| VSAN 6.0 | March 2015 | All-flash 64 Node cluster 2x Hybrid Speed |
| VSAN 6.1 | September 2015 | Stretched Cluster Replication RPO of 5 minutes 2-node ROBO |
| VSAN 6.2 | March 2016 | Deduplication Compression QoS |
We really enjoy the pace in which this product is being developed and in such a incredible pace. Keep it going guys!
The main new features for this 6.5 release which is announced during VMworld EMEA 2016 (Oktober 2016) according to us among others are:
- iSCSI-Access
- Direct Connect for ROBO
iSCSI-access
VSAN target service makes it possible to use a VSAN as a iSCSI-target (what’s in a name!) and allows these targets to be presented to external (non-virtual) workloads (i.e. MSCS clusters or physical workloads). So no more need for additional storage boxes to tie to your (legacy) physical workloads, you can now also use VSAN for these workloads.
Also allows for SPBM (Storage Policy Based Management) for these targets, so you can set dedup / compression / raid-level (1,5 or 6) and applies them respectively to these iSCSI-objects in your VSAN-datastore.
Direct Connect for ROBO
VSAN 6.5, allows for directly connecting to VSAN-nodes together in a ROBO-situation with a couple of crossover-cables which lifts the need for 10Gb network switching connecting the nodes.You can now suffice with only 1Gb-switching for management and witness traffic. So it simplifies the set-up and decreases the cost for setting up VSAN 6.5 for remote offices.
Further improvements
A short list of other enhancements / changes in the VSAN 6.5-product:
- All-Flash now available in VSAN STD license (Compression en Dedup still needs ADV/ENT-licensing) and new VSAN ADV for ROBO offering.
- Containers support. VSAN allows as a source of persistent storage for VIC (vSphere Integrated Containers)
- Updated REST API and extended PowerCLI module for VSAN
- Enhanced hardware support
