#VSANchat#VSANchat - Talking VSAN 6.2! Join #VSANchat as we discuss Virtual SAN 6.2!
VMware vSAN
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...!

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 ;-)

Q2: Great to hear the excitement of VSAN 6.1 features. So, how do you leverage #VSAN for your business?
brugh
12000 user Lync platform
Tim Davis
ROBO sites where they have old physical servers ready to refresh. Rather than buy new SAN for ROBO, vSAN works perfectly.
Steve Smith
fairly pedestrian deployment, backing our new VDI environment. I assume this is one of the top use cases at this time.
Lieutenant VSAN
maybe a dedicated Oracle cluster so you don't have to worry about Oracle licensing...
Michael Haag
We've seen some great comments on #VSAN for ROBO and some VDI questions ... how else are people using #VSAN (or seeing it used)?
Thomas Findelkind
I hope a refresh for EVO RAIL with 2 node setup will follow
Michael Haag
@VmAlchemist VDI is definitely a popular use case - the cost, predictable scaling and performance make that a great fit ... are you deploying on all-flash or hybrid?
Rodrigo Gazzaneo
@MichaelJHaag curious about mission critical apps on #VSAN too
Lieutenant VSAN
@vGazza VSAN 6 is ready for mission critical apps!
Victor Cenac
replaceing 96 TB iSCSI SAN with 5 node VSAN
Rodrigo Gazzaneo
@LTVSAN no doubt about it. Curious about references.
Steve Smith
@MichaelJHaag We're deploying hybrid -- 2 disk groups per host --- 1.6TB SSD and 7x2TB SAS disks
brugh
@vicenac curious how you sized it; does it look anything like what http://virtualapplia... would advise?
Jase McCarty
We're seeing lots of adoption of Virtual SAN for VDI, which many customers see as Mission Critical.
Pooja
@vGazza Here is an example of T1 apps (Oracle, SQL server and a bunch of medical apps) on VSAN in healthcare: http://www.vmware.co...
Rodrigo Gazzaneo
@jasemccarty very true. Nothing more critical than end user computing platform.
Rodrigo Gazzaneo
@vmw_pooja thanks! Great use case!
Aaron Kay
Replaced aging iSCSI/FC SANs at multiple sites with VSAN clusters. Better performance, fault tolerance, cheaper, more flexible, more GB/dollar, easier to deal with.
VMware vSAN
Q4: Why do you use VMware Virtual SAN over other solutions available?
brugh
no storage management and the ease of flash
Lieutenant VSAN
so easy Gump could use it.
Aaron Kay
Cost to performance/capacity ratio, ease of management/ability to make changes to hardware layout/expansion.
Tim Davis
Seamless integration into the hosts / vSphere.
Aaron Kay
VSAN just works.
VMware vSAN
@num1k We think so too! :)
RyanGarvelink
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.
