I was listening to the podcast yesterday regarding the version 11.0 announcement. A 50TB capacity will be available as well as tiered storage for optimizing to flash and SSD. No TRIM/UNMAP yet, but it's on the way according to the announcement.
08-19-2013 03:42 PM
I hope one day they sort out whatever is needed to get unmap to work as thin provisioning volume growth is definitely a long-term problem, but the rest of the things they mention all sound good. Looking forward to the release.

so you have to pay to upgrade your VSA to have storage tiering?
seems like this should be free.
What's the word? It's almost like they are renaming the product
08-20-2013 06:30 AM
where did you read that? The blog post I read did talk about three tiers of licenses... 3/10/50 w/ the 3TB one limited to 3 nodes and no tiering, that kinda implies that the 10TB one (AKA the current solution) includes Tiering.... one thing I"m not clear on is if that tiering is inter-node or intra-node (IE, will it auto-tier between SATA nodes and SSD nodes or is it a node with SATA and SSD drives attached).
08-20-2013 06:55 AM
How you implement the tiering was my question as well.
My initial impression was that you would need to provision a physical disk group on the server raid controller using SSD, SAS, or go with PCIe flash, (whatever your high-performance disks are) then create a virtual disk on that storage and designate it as the high performance tier in the CMC.
If above is the case, how does it work if your server uses smart-cache like the p420?Perhaps the two are complimentary?
Lot's of questions...
08-23-2013 04:37 AM
You have this in writing somewhere?
My SE1120 with P420/2gb FBWC is ready! 1.5TB of read ssd caching for raid-5 volume can be reconfigured to do both read/write tiering?
Honestly I'd be more happy if they would come up with host side unified cache design and write-back caching.
ie you are on same node as VSA, you write preferred to VSA local node first. It will ACK then you continue.
Read caching could be done too on host side :)
Also regarding trim, if we had RLE compression wouldn't that take care of unmap/trim? simple zero compression would take of that?

Some of my support contracts actually expired, but I haven't had any issues downloading updates through the CMC. I think so long as your nodes are licensed or within the evaluation period there shouldn't be any issue upgrading.
In the podcast it was stated that tiering and capacity increases were VSA only features for now.
The tiering implementation in 11.0 is a good start, I'd like to see some RAM utilization for cache similar to Nexenta/ZFS in the future.
Since the VSA is software-defined storage I'm not sure how much host-side integration is possible. A DSM equivalent for ESXi would be nice along with better vCenter integration. I would love to have my CMC show up as an extra tab in the vSphere client similar to how the VMWare VSA is integrated.

Seems that for once vmware might hold the upper hand. I really am looking forward to see how that "evacuate" a VSA host feature works.
The main thing that storevirtual had was iscsi so if a node failed, all the hosts connected did not crash (they had no form of CARP/VRRP for their nfs) whereas ISCSI connects to multiple vsa and sustains a storage node failure quite happily.
SCSI_UNMAP support in esxi 5.5 will definitely put the pressure on storevirtual to support trimming!
I think competition is good, it ensures everyone gets the new features they are wanting.
What I'd love to see is a good reliable NAS (nfs/smb) to run on the FOM to dish out multiprotocol with storevirtual. that would be hot. the microsoft smb is good but their nfs is horrible

new version 11 is available for download on HP portal now:
HP StoreVirtual - Receive for free...
10-21-2013 05:50 AM
It says CMC should offer the program starting on Nov. 11th.... wish they wouldn't bother with the symbolic 11/11 release date or if they really cared they should have released it two years ago :)
10-29-2013 05:20 PM
Adaptive optimization works great, you get two tiers and all storage. It is not the same as HP SMARTCACHE or LSI CACHECADE! if you allocate 2TB to SSD and 8TB to RAID-5 SATA , you get a total of 10TB usable! (VSA).
You can also use HP smart cache along with this to make it even faster. Or do a split like 15K SAS RAID-10 tier-0 and 7.2K SAS RAID-5/6/50/60!
Awesome! just upgrade! Remember that if you upgrade to 11 - you may not be very happy with deprecation of windows 2003 (VSS/MPIO) but I have not verified that myself.
With 1 VSA (no redundancy), it takes about 15 minutes to install CMC and a node. The only thing you should do is power down the VSA, change the MAC ADDRESS to Manual to match your licensing, then continue setup. Otherwise you will get a dynamic mac address and that could turn out BAD!
Also all PVSCSI and VMXNET3 ! awesome sauce!
I have to say really impressed.
Now all we need is re-thinning, but I'm happy!! This blows away performance from 10 due to Adaptive Optimization.
I may post a single node test with 40gbe mellanox connect-x3 to a single tier of 2TB SSD and 5TB of 15K SAS and some other combinations including cachecade and hp smartcache/smartpath to see how much faster this vsa can scale!
11-01-2013 08:57 PM
We will be running the VSA test on a P4300 G2 ugpraded to P420/1gb FBWC and L5639 CPU with 12gb of ram - esxi 5.5 - dual 10gbe port (emulex be2). 8 LFF drives but i'd be glad to stuff some SSD in there.
Only had $600 budget for server so that had to do. [sas and ssd drives already had laying around]
Start simple? 512GB of SSD[r1] and 2.5tb of raid-5 15K 450GB?
could do 512 SSD HP Smartcache, 2.5TB tier-0.
256 HP smartcache, 256 tier-0 ssd, 2.5TB TIER-1 15K SAS RAID-5
then 512 tier-0 R1 SSD, 2.5TB Tier-1 15K SAS RAID-5
then repeat with raid-10?
I can do 2 machines once I figure out how to get 10-20gbps of speed out of the box.
It would be cool to do the pepsi challenge against the Hyper-V.
I'd like to hear from HP about this: The large-scale workloads with intensive I/O patterns require adapter queue depths greater than the Paravirtual SCSI (PVSCSI) default values. Current PVSCSI queue depth default values are 64 ( for device) and 254 (for adapter). You can increase PVSCSI queue depths to 256 (for device) and 1024 (for adapter) inside a Windows virtual machine.
So can you not change these values in *nix? How does that affect ESXi versus Hyper-V2012/r2 performance? !!
Hp let us know!!
11-07-2013 09:03 AM
So you have PCI-E FLASH,RAMSAN on your VSA but can't push each LUN to 255 QD (or more?)
2 vcpu with default settings are not going to push that 40gbe nic and storage subsystem to 1 million IOPS!
The problem is of course simple - if you can't push 255 QD your SSD will never get a true workout. If you can't dispatch i/o against more VCPU, you will not be able to handle the i/o - Both EThernet and Storage this is true!
What I would suggest is the ability to tweak both storage and networking for the VSA - esxi -> and hyper-v so you can push hard.
I would suggest that a STOREVIRTUAL VSA 11 with TIER-0 of RAM [backed with flash], and TIER-1 of SSD might be able to reach 1 million IOPS with the ability to add more VCPU, tweak Storage Queue Depth/Ring, and likewise tweak the VMXNET3 subsystem to run 4,5,6,7,8 (or more) vcpu.
So here's the deal! If anyone can get logged into their lefthand (shell) VSA..
try this - or maybe HP lefthand engineers can tell us the whole story.......
[I am asking lefthand engineers, not end users ..! DO NOT TRY THIS AT HOME KIDS! ]
Append the following to kernel boot args ( edit /boot/grub/grub.cfg) and reboot the system.
You can verify the changed queue depth by doing a cat on these module args i.e.
$ cat /sys/module/vmw_pvscsi/parameters/cmd_per_lun
$ cat /sys/module/vmw_pvscsi/parameters/ring_pages
(link to older source: http://permalink.gmane.org/gmane.comp.emulators.qe
#define PVSCSI_DEFAULT_NUM_PAGES_PER_RING 8 #define PVSCSI_DEFAULT_NUM_PAGES_MSG_RING 1 #define PVSCSI_DEFAULT_QUEUE_DEPTH 64 #define SGL_SIZE PAGE_SIZE
11-25-2013 09:26 AM
the VSA main page says Nov 30th last time I checked. Not sure why they delayed it. I know you can download it direct right now (and I did), but I'm going to wait until after the update becomes available through CMC before I install it on my SAN.
11-25-2013 09:54 AM
Yea they pushed it back, which is what I meant by "not surprised". I don't think the LeftHand/StoreVirtual team has ever hit a date they've set. Hell SMI-S has been coming in the "next version" for over 2 years.
How would I go about upgrading without waiting for it to be pushed via CMC? I want to move my HyperVisors too 2012 R2 and I'm getting sick of waiting.
11-25-2013 10:51 AM
the software is available for download through their software system. I can never remember exactly how I get there, but I think one way to get there is through the "try VSA" link now it will give you the v11 software. I downloaded it back around the 15th and upgraded my CMC install to v11. CMC doesn't show an upgrade available for my nodes/management group, but I have all the software to upgrade the DSM/app snapshot software on my servers to v11 and can do that.... I haven't yet because I haven't had the free time, but I plan on doing it over thanskgiving some time. As for upgrading nodes, I don't know how to do that beyond just replacing each VSA individually which IMO isn't worth the trouble.
11-28-2013 05:13 AM
Yes, you cant download version 11 from Software Depot
But when we can see this version in CMC?!
11-29-2013 10:24 AM
In other words, you can't (easily) upgrade already deployed nodes without waiting for the CMC upgrade which was due Nov 11, then before the end of Nov.
Now it's the end of Nov, and it's still not released. So done with the LeftHand/StoreVirtual product line. They're always 10 steps behind everyone else and 20 steps behind their own promises.
At the price point of the StoreVirtual line, what you get feature wise and both support wise is ridiculous.

StoreVirtual 11 Download page updated to now show "CMC Online Upgradeability available in early December 2013".
I'll be sure to hold my breath.
