Thanks to everybody for joining #VSANchat today! If you have any questions around VSAN, please feel free to tweet to us @vmwarevsan! You can also check the Virtual Blocks blog for more information at blogs.vmware.com/vir...!
How do you define tiering? Are you looking for tiering at the persistent data layer? We support hybrid systems, but the flash in those is used as a cache.
I think this is a request for having different types of disk groups in the same cluster. Some all-flash, others hybrid. We've heard this request before and we'll highlight it to PM again Ryan. Is it something you would use?
@CormacJHogan We would absolutely like to see different disk groups in the same cluster. 5 hosts, 3 groups/host, 1 all fash group, 2 hybrid group would rock for me!
@MichaelJHaag Cost and also flexibility. It's a tough sell to move someone from a fully tiered storage array with different disk options to only the single disk group.
I'd think that with the performance of Hybrid VSAN, you could get a good mix of tiering/performance. Hybrid can provide 40K IOPS/host, add Caching via SPBM, could meet the need.
using SPBM, with cache reservation and stripe width, a VM or single vmdk can be individually given more performance. Several factors to determine though.
Any improvements with Horizon integration? Ex: Default policy is 0 FTT on floating pool os disks, but View does not do anything to compensate in case of a node failure. (such as recognize the failure or automatically provision more vms on good hosts)?
Great question and feedback ... Virtual Desktops are one of our leading VSAN use cases ... we have VDI policies integrated in Horizon but are continually working with the Horizon team to do more.
- Big focus of the launch was on great site protection, improved management and exciting new deployment options (i.e. like new flash technology for greater performance)
@ALDTD Thanks. And I guess the idea is to host multiple witness on the primary, and have multiple ROBO sites managed from there? Can you share numbers?
@CormacJHogan We currently have 10 ROBO sites, 2 of which are running vSAN. Ideally, we'll roll out vSAN on all subsequent ROBO roll outs. Not all our sites have ROBO. Only larger sites when they have a bunch of physical footprint that are refreshed.
Stretched Cluster, 2-node/ROBO, SMP-FT support, health check enhancements such as alarm on failures and new flash device support (off the top of my head)
