vMSC Support now extended to 10 msec RTT

Amidst all the fun of EMC World, there is some really important news for the VPLEX Metro and VMware community that I wanted to ensure was not lost.

What was supported until now

Prior to this change, the official vSphere Metro Storage Cluster (vMSC) support stance was that VMware HA and vMotion was supported until 5 msec RTT (Round Trip Time). There was an additional wrinkle. vMotion was supported up to 10 msec RTT with your vSphere Enterprise Plus licensing. And VPLEX Metro supported it. However, VMware HA was not supported up to 10 msec RTT.

What has changed

The big change that happened is that now as a part of vMSC both VMware HA and VMware vMotion have now been extended to be supported with VPLEX Metro up to 10 msec RTT. This qualification has been completed with both PowerPath/VE as well as with NMP (Native Multi-pathing) for the non-uniform access mode (i.e. non-cross connected configuration). This support is available starting with vSphere 5.5 and GeoSynchrony 5.2.

vMSC 10 msec RTT support

The VMware Knowledge Base article is updated here.

Many thanks to the VMware Ecosystem Engineering team as well as key technical leaders on both the VMware and EMC sides for helping drive this. This has been a long time coming.

Spread the word!!

2014 Launch Post 1: Software Defined Coolness: VPLEX Virtual Edition!!

2014-04-08 One Correction below

On April 4th, 2014, as part of the Data Protection and Availability Division (DPAD) launch, there were three VPLEX and RecoverPoint items that were launched or GAd:

  • VPLEX Virtual Edition – Availability late Q2
  • MetroPoint Topology – Joint capability of VPLEX and RecoverPoint – Availability Late Q2
  • VPLEX Integrated Array Services – Available now

This is the first in a series of posts to walk through what was launched / delivered.

The drivers towards a VPLEX Virtual Edition

Data center infrastructure is undergoing a massive shift. Virtualization in the data center has had a profound impact on customer expectations of flexibility and agility. Especially as customers get to 70+% virtualized, they have the potential to realize tremendous operational savings by consolidating management in their virtualization framework. In this state, customers typically do not want to deploy physical appliances and want everything handled from their virtualization context. Similar changes in networking and storage have meant that the basic infrastructure is now completely in software running on generic hardware. This is the software defined data center. VPLEX has been no stranger to this conversation. Especially given the very strong affinity of VPLEX to VMware use-cases, customers have been asking us for a software only version of VPLEX. That is precisely what we have done. This past week, we launched VPLEX Virtual Edition – with a GA towards the end of Q2.

What is the VPLEX Virtual Edition and what does it do?

The VPLEX Virtual Edition (VPLEX/VE) is a vApp version of VPLEX designed to run on an ESX Server Environment to provide continuous availability and mobility within and across data centers. We expect this to be the first in a series of virtual offerings. In comparison to the appliance, all the VPLEX directors are converted into vDirectors. For the first release, the configuration we support is called the ‘4×4’ – this will support four vDirectors on each side of a VPLEX Metro. From a configuration standpoint, that is the equivalent of two VPLEX engines on each side of a VPLEX Metro cluster. Each side of VPLEX/VE can be deployed within or across data centers up to 5 msec apart.

VPLEX/VE supports iSCSI for front-end and back-end connectivity. For the initial release, we have decided to support only the VPLEX Metro equivalent use-cases. Most of the VPLEX Local related use-cases can be addressed by a combination of vMotion and storage vMotion. To list the use-cases:

  • The ability to stretch VMware HA / DRS clusters across data centers for automatic restart and protecting VMs across multiple data arrays
  • Load balancing of virtual machines across data centers
  • Instant movement of VMs across distance

From a performance perspective, VPLEX/VE is targeted up to a 100K IOPS workload. Obviously, the true performance will depend on your workload. The deployment is designed to be customer installable from the get go. There is an installation wizard that guides you all the way through the installation. When GAd, please refer to the release notes to determine what kind of ESX Servers are supported for VPLEX/VE. The vDirectors need to be loaded onto separate ESX Servers such that no two vDirectors are deployed on the same ESX server. This is done so as to give the system maximum availability. Running application VMs on the same ESX server as that running the vDirector is supported. This means that you should be able to use your existing ESX servers (subject to the minimum requirement that will be established for the vDirectors).

The way that an I/O will flow is from the application VM (via iSCSI) to the VPLEX/VE vDirector VM and from there to the iSCSI array connected to VPLEX/VE. Speaking of which, right out of the chute, we support VNXe arrays. We will add other iSCSI arrays over time.

One of the more interesting changes that we have made with VPLEX/VE is the way that it is managed. Since VPLEX/VE is tailored for ESX servers only, our management interface to VPLEX/VE is completely through the vSphere Web Client. Here are some screenshots of how VPLEX/VE management looks. The coolest part for me is that you can go from creating your VMs, setting up an HA cluster, all the way to creating a distributed volume all within the vSphere Web Client. _VERY_ nifty! In addition, we have now enabled VPLEX/VE events and alarms to show up in the vCenter Event Viewer. For all practical purposes, this is a seamless vApp designed for your vSphere environments.

When a distributed volume is provisioned for VPLEX/VE, it is configured as a vmfs 5 volume and made available as a resource to vCenter.

With VPLEX/VE, we have had the opportunity to do a lot of things differently. One of our guiding principles was to not think of it as a storage product but rather to think of it as a product designed for VMware environments and targeted to an ESX Administrator. Naturally, I cannot wait to see this get into our customers hands and to see whether we have hit our marks and what adjustments are needed.

Equally importantly, this is a strategic imperative within EMC. You can expect to see a lot more of our product portfolio embarking on the software defined journey. There are a lot of intersects within the portfolio that we have only begun to explore (HINT: Composing software is a lot easier than composing hardware!).

Frequently Asked Questions

Since launch, I have seen a ton of questions on twitter, on internal mailing lists and via people directly or indirectly reaching out to me. So, here are the collated answers:

  • Is VPLEX/VE available right now?
    • A: VPLEX/VE will GA towards the end of Q2.
  • Will VPLEX/VE support non-EMC arrays?
    • A: As with VPLEX, we expect to qualify additional EMC and non-EMC arrays over time based on customer demand. Expect new additions fairly quickly after GA
  • Will I be able to connect VMs from ESX clusters that are not within the same cluster as the one hosting VPLEX/VE?
    • A: Yes No
  • Will I be able to connect non-VMware ESX hosts to VPLEX/VE?
    • A: At this point, we only support VMware iSCSI hosts connecting to VPLEX/VE. This is one of the reasons the management has been designed within the vSphere Web Client
  • Can I connect VPLEX/VE with VPLEX?
    • A: VPLEX/VE is deployed as a Metro equivalent platform (i.e. both sides). Connecting to VPLEX is not supported. If there are interesting use-cases of this ilk, we would love to hear from you. Please use the comments section below and we can get in touch with you.
  • Is RecoverPoint supported with VPLEX/VE>
    • A: Not today. So, I am explicit – the MetroPoint topology which also launched last week is also not supported with VPLEX/VE
  • Is VPLEX/VE supported with ViPR?
    • A: At GA, ViPR will not support VPLEX/VE. Both the ViPR and VPLEX/VE teams are actively looking at this.
  • Does VPLEX/VE support deployment configurations other than a 4×4?
    • A: Currently, 4×4 is the only allowed deployment configuration. Over time, we expect to support additional configurations primarily driven by additional customer demand.
  • Will VPLEX/VE be qualified under vMSC (vSphere Metro Storage Cluster)?
    • A: Yes.

Takeaways from VMware Partner Exchange 2014

I just came home from the ever lovely San Francisco to a winter wonderland here in Boston. The picture on the ground in Boston was just as completely different from San Francisco as I believe the data center in five years will be from the data center of today. The picture has started to emerge out of the haze but it is not completely clear what the final picture will be when the fuzziness disappears.

In walking through the solutions floor and talking to various partners and listening to the key notes, there are some interesting things I took away and thought would be useful to share.

  1. Flash is changing the data center – And it is early days yet: For the longest time in the compute, network and storage trifecta within the data center, the storage portion has been the slowest typically. With flash, that equation has started to change. With flash there has a dramatic change in the IOPS and latency equation on the storage front. We are seeing some very interesting plays on the usage of flash. Some of the changes are obvious – the sheer speed of flash enables a paradigm shift. You can already see many different layers trying to attack the problem – take the FVP from PernixData or VSAN from VMware or which try to aggregate server side flash or EMC’s XtremSF with XtremCache which does intelligent data tiering at the server level. My bet, this is just the first domino. How will flash change the application layer? There are a _LOT_ of flash plays out there. Innovation at the speed of flash, I guess. Not all these ideas will work but man, what a ride it promises to be.
  2. Software Defined – you ain’t seen nothing yet: This seems like a buzzword until you peer through the hype cycle. While the most obvious impact is the conversion of hardware elements into pure software, my bet again is that the impact is going to be far more profound than most of us realize. Infrastructure is being separated from hardware right in front of our eyes. The server side has already undergone this dramatic transformation and the profound impact of that is in front of our eyes. Storage and network are up next. There is one other implication. At the point that you have storage and network virtualized, your entire infrastructure is no longer tied to hardware. We have seen an example of what can happen with use-cases such as those seen with VPLEX. What implications does this have for management, for the definition of a data center and what we architect, train and build for.

These are seismic changes which promise to change the landscape of computing. This impacts data center practitioners, partners who sell to data centers, and vendors who are trying to build for these new data centers. Only time will tell how all of this will shake out. We live in very interesting times in the technology industry – enjoy the ride, it should be fun!

PS: One other takeaway for me: I should invest in a snowblower. More on that later 🙂

VMware Partner Exchange: The VPLEX/RecoverPoint Angle

In about a week’s time, I will be heading to San Francisco for VMware Partner Exchange.

EMC is putting together a fabulous boot-camp together for our partners on Monday, February 10th from 8:30 AM – 4:30 PM. The session number is 3579-SPO: “EMC’s Game Changing Solution Roadmaps, Resources & Partner Programs” (Content Catalog Link). This is an NDA only session focusing on where the EMC portfolio is going (YES! roadmap items will be discussed – hence the NDA) and how this portfolio and direction can enable business for our partners. The NDA can be signed right outside the session hall.

Chad Sakac gets top billing at the bootcamp with a marathon 2.5 hour session to kick the day off. Post that session each of the individual solution owners and BUs will present the next level of depth on the partner opportunities. The session lengths range from 30 – 45 minutes. Try putting all the things that are going on in any one division in 30 – 45 mins and you can imagine that each speaker is left with a LOT to say and very little time.

On the VPLEX and RecoverPoint front, this will be our first public event as a part of the Data Protection and Availability Division. Extremely exciting possibilities and a lot of things that are in the works. Phil (@vPhilGeorge) provides a sneak peek of all the DPAD activities at VMware Partner Exchange here.

In addition to the boot camps, we will have also have a floor presence on the Solutions floor at the EMC booth. Please do stop by Booth #401 – we have tons to tell you about and questions we can answer. Plus, we will also be doing the ever popular Hands On Labs. These do not need any registration and are on a first-come-first-served basis.

Specific to VPLEX and RecoverPoint, we are doing an additional one-hour under NDA sessions. Space is limited for 6 – 10 partners even with standing room. Our Channel Marketing team is coordinating attendance for this session. Yossi Saad and I will be talking to these partners to dive deeper into the roadmaps for RecoverPoint and VPLEX. We are aiming to cover some incredible new work that is going on in the VPLEX / RP portfolios to learn how we can bring these game changing technologies to market with our partners.

Last but not the least, if you are going to PEX and would like to have a VPLEX / RP chat, please do not hesitate to reach out. I would love to connect with you and set some time up to understand your business and VPLEX and RP can be tools in your arsenal to make you even more successful.

Look forward to seeing you there!
