Is tiering anywhere on the road map?
Michael Haag
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.
Victor Cenac
fast groups / slow groups
Steve Smith
This is the role of storage policies IMHO.
Cormac Hogan
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?
Victor Cenac
yes, different speeds groups for different policies
Aaron Kay
@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!
Cormac Hogan
I'll feed this back - thanks folks
RyanGarvelink
@CormacJHogan I work for a VMware partner and would say 80% of my vSAN calls have that exact request.
Michael Haag
Is the primary reason costs or is it for other reasons, like to have primary VMs on dedicated, faster storage to ensure the right QoS?
RyanGarvelink
@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.
Victor Cenac
I think it is achieving the same result with less striping, so it's cost
Jase McCarty
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.
Jase McCarty
using SPBM, with cache reservation and stripe width, a VM or single vmdk can be individually given more performance. Several factors to determine though.
Philip Chapman
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)?
Michael Haag
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.
Victor Cenac
I'd second that automatic recovery/failover would be nice
Steve Smith
Agree -- better storage policy customization and tighter integration with Horizon would be very welcome.
Cormac Hogan
@VmAlchemist Are there any policies/capabilities in particular you'd want to modify. We can take this input back to the View team
Steve Smith
would like to be able to set a storage policy by pool (configured in Connection Server).
Victor Cenac
General Licensing: In a VSAN cluster, server that are not contributing storage have to be licensed, too?
Michael Haag
yes, that is correct
VMware vSAN
Q1: Let's talk about the features of VSAN. What are some of the new features of #VSAN 6.1 that you find most appealing?
Rodrigo Gazzaneo
the stretched cluster is very cool!
Jase McCarty
ROBO 2 Node support!
Michael Haag
- 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)
Mike Ellis
Stretched Cluster is very cool
Ankit Mehta
Virtual SAN Stretched Cluster and ROBO, #VSANChat #vExpert
Tim Davis
Robo 2 node is going to be game changer for my team.
Cormac Hogan
@ALDTD would love to hear your thoughts on the witness. Physical or appliance? On-prem or would you use a vCloud Air solution if/when available?
Michael Haag
@ALDTD That's great to hear ... what's the biggest appeal ... cost/simplicity/other?
Rodrigo Gazzaneo
clustering support on 6.1 is cool. #Microsoft and #OracleRAC
Lieutenant VSAN
can I haz some ULLtraDIMM support too?
Tim Davis
@CormacJHogan We'll host the witness appliance in our on-prem primary vC.
Tim Davis
@MichaelJHaag Cost. Not having to use 3 compute nodes when we could get away with 2.
Rodrigo Gazzaneo
@CormacJHogan witness on #vCloudAir seems a natural fit for #VSAN ROBO
Hugo Phan
@CormacJHogan Whats the networking/vShield Edge requirements if using Witness in vCloud Air?
VMware vSAN
We're also very excited about ROBO and Stretched Cluster!
Cormac Hogan
@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?
Michael Haag
@LTVSAN Absolutely ... VSAN now supports ULLtraDIMM as well NVMe ... we had an awesome 64-node demo with NVMe from Intel at VMworld!
Cormac Hogan
@hugophan Still working out those details Hugo.
Lieutenant VSAN
also really like that vSphere Replication will now support 5 min RPO when used when replicating from VSAN to VSAN.
Tim Davis
@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.
Cormac Hogan
@ALDTD Thanks for sharing Tim. Sounds like an interesting project for sure
Cormac Hogan
@hugophan He's never around when you need him ;-)
VMware vSAN
Okay, let's get started!
Lieutenant VSAN
What's new in Virtual SAN 6.1 @MichaelJhaag?
Cormac Hogan
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)
Michael Haag
- Answers are rolling in to this on other question from @vmwarevsan
