I have a customer who wants to do a PoC for a Oracle DB that is currently using Fusion-IO

100k IOPS per host. tested in beta.

sub ms latencu is possible with all-flash configurations. Working on such a design now for SQL based e-commerce.

* latency

@BlueShiftBlog you should see the performance number that SanDisk and Micron posted around SQL and Oracle

Did. I like how the two tier design accommodates less expensive flash for capacity tier.

@PunchingClouds I'll have to find that one, they would be interested to see that

@ck_nic http://itblog.sandis...

Every test we've run on all-flash produces the same results -- stupid fast. I don't think we've found the limit yet.

Gotta love stupid fast speed! Kind of like Ludicrous speed #Spaceballs!

@jasemccarty anybody who mentions #Spaceballs is ok in my book

Gotta love ludicrous speed for mixed workloads!

Yuri check the performance numbers release by Micron and SanDiks for SQL and Oracle performance numbers. What you'll see is out of the box no tuning or anything.

thanks, i'll do

Rolo has a partner test that showed ~500K TPC-C per host. And there was plenty of headroom left. 4 nodes, 2m TPC-Cs. Like I said, stupid fast ...

@BlueShiftBlog Thank you for the link

Check the VCG and look at the IBM Flex 10 systems, and soon Dell FX2

more and more to come

are any of these part of the VSAN Ready Node? Any published/certified offerings available?

+1 for blades.

This to me is a much more interesting use case then rack-mounts, while it may not scale as nice, i can now have compute and storage in the same tiny footprint

@stu I believe we have the IBM system listed now. But when we GA there will be more

any major changes to be mindful of between 55.HCL and 6.0 HCL?

you mention GA, will it GA with the rest of 6.0

yes, there's a new classification system for flash drives that favors bigger devices.

@chuckhollis was just specing out some 1600GB beasts :)

not specific to 5.5 v 6.0, but there is a ton of new certs coming around 12Gb SAS devices and NVMe for flash

@stu I need to come on the cube and tell you what's up 1:1 for serious : )

looking forward to the details. Simplicity and broad set of offerings are competing forces. And blades are usually designed for external storage.

pay attention to NVMe, in particular -- that party is just getting started

Support for High Density Storage Systems with Direct-Attached JBOD, Manage externally connected disk enclosures and leverage existing investment in blade-based
architectures; flash acceleration is provided on the server or in the external.

Just make sure that when you see the term JBOD doesn't mean you go to Fry's electronics and build something there and plug to the blades. We are talking about specific certified systems

my WDD Green Drives in my Synology isn't going to cut it?? #sarcasm

Right for guys new to #VSAN if I'm just using attached storage today, why jump into this?

1000+ paying customers, most will point to 1. extreme simplicity, 2. very cost effective, and 3. impressive performance.

much of that derives from the fact that it's tightly integrated with vSphere -- built in, not bolted on.

Take advantage of all the local storage that we have on the servers!, with VSAN now we have provision it and use it way better

easy of management, and the ability to dynamically adapt to the demands of the workloads and scalable flexibility. Linear scale man. by single disks and not just by a node think about that $$$$

RT: @chuckhollis Chuck Hollis 1000+ paying customers, most will point to 1. extreme simplicity, 2. very cost effective, and 3. impressive performance.

if a customer just spend big dough on a new traditional array, i don't see them adopting, yet. However in new installs or where a storage refresh needs to happen i more serious conversations seem to be happening.

often, it's a vSphere team that wants control of their own destiny :)

Easy of Management, Same budget as Servers.

ease of management if you are avoiding having a storage team. It increases operational considerations if you already have a set Storage vs. Compute ops model.

do I get more pay as an admin now ? Is there a certification I can get on VMware Virtual Storage 6

@chuckhollis The way I see it, is that we, the vSphere Admins are always depending on the storage team to provide us with Space, now with vSAN, we take that limitation away

@punchingclouds is working on a VSAN 6 cert.

you damn right! VSAN 6.0 Certification in the works baby

@chuckhollis Nice going!

derived from Virsto tech, more perf, vastly improved snaps: quantity and performance

what's different about the snapshots? is it a cost issue or tech advantage

@chuckhollis can you describe how the snaps are better, in a more technical way??

the snapshots in vSphere are pretty limited ... VSAN 6.0 now has array-class snapshots: 32 per VM, minimal performance hit

@chuckhollis thats pretty impressive.

(describe in a more technical way) -- hard to do on Twitter :)

@chuckhollis i can't make it easy, no fun in that :)

and I keep wanting to use my hands :)

how does it handle non bursting steady state of writes vs VSAN 5.5

log based, so predictable performance on steady-state writes
