In EMC-land, we have maintainance/service releases for major products – and often these don’t get the glory of the big launches, but contain a TON of important stuff.
Inyo is the code name for the currently shipping VNX Operating Environment that covers NAS and Block functionality (VNX OE 32/7), and Maintenance Release 1 (MR1) shipped to manufacturing on the 19th and is available for general download today (feb 22nd).
- Critical VAAI block XCopy fixes (Primus emc313487 – go to https://support.emc.com and just search for the Primus case)
- Huge VAAI File Fastclone improvements
- SMB 3.0 support!
- ODX support!
A little more detail, first on VAAI File Fastclone – this is used predominantly in vCloud Director cases on NFS datastores (something we experienced at SAP, a large VNX customer, but of course there are loads of customers using vCloud Director on VNX NFS). The VAAI assist uses the storage subsystem to “hardware accelerate” the process of creating a VM clone/snapshot. Internal to the VNX today, there can be some recursion of the snapshots of files at the filesystem layer, and then it implements a full file copy. Looking at the case, we made optimizations – and they are BIG (like 4x-10x better), and why keep them for just SAP – good to share with the world :) Here are the before/after that we saw in testing:
|VM copy within a fs (VAAI)||20-60 MB/s||250 MB/s|
|VM copy between fs same DM(VAAI)||20-60 MB/s||270 MB/s|
|Bulk test – copy 200 VMs (VAAI)||N/A (took too long)||660 MB/s|
On the SMB 3.0 and ODX support – this is a really big deal for our customers using Microsoft (and who doesn’t). I think we actually might be the first of the NAS folks out of the gate with SMB 3.0 – which is a big leap forward in NAS and VMware – not only in the underlying protocol itself, but that SMB can be used with Hyper-V in a way that is very similar to how NFS can be used with vSphere (many of the SMB 2.2 to 3.0 improvements result in SMB being much, much better than in the past for transactional workloads). I could be wrong (I try to avoid talking about other folks like the plague as people jump all over me and assume I’m being competitive – but I do have many NetApp readers) – I believe the NetApp SMB 3.0 support is targeted at ONTAP 8.2.
ODX is a bit of a “catchup” as it’s analagous to the Block XCOPY support in vSphere – but great to see it for our Microsoft-focused brothers and sisters.
Great stuff – and customers, you can get it on Powerlink, but better place is https://support.emc.com (and yes, we are shifting away from the Powerlink model to the more social model – take a look at https://support.emc.com and https://community.emc.com to see the future of Powerlink)
