Future Proofing Storage Acquisitions Without A Crystal Ball

Dealing with an unknown future without a crystal ball

I’ve said it before and I’ll say it again. Storage Spaces in Windows Server 2012 (R2) is are the first steps of MSFT to really make a difference (or put a dent into) in the storage world. See TechEd 2013 Revelations for Storage Vendors as the Future of Storage lies With Windows 2012 R2 (that was a nice blog by the way to find out what resellers & vendors have no sense of humor & perspective). It’s not just Microsoft who’s doing so. There are many interesting initiatives at smaller companies to to the same. The question is not if these offerings can match the features sets, capabilities and scenario’s of the established storage vendors offerings. The real question is if the established vendors offer enough value for money to maintain themselves in a good enough is good enough world, which in itself is a moving target due to the speed at which technology & business needs evolve. The balance of cost versus value becomes critical for selecting storage. You need it now and you know you’ll run it for 3 to 5 years. Perhaps longer, which is fine if it serves your needs, but you just don’t know. Due to speed of change you can’t invest in a solution that will last you for the long term. You need a good fit now at reasonable cost with some headway for scale up / scale out. The ROI/TCO has to be good within 6 months or a year. If possible get a modular solution. One where you can replace the parts that are the bottle neck without having to to a fork lift upgrade. That allows for smaller, incremental, affordable improvements until you have either morphed into a new system all together over a period of time or have gotten out of the current solution what’s possible and the time has arrived to replace it. Never would I  invest in an expensive, long term, fork lift, ultra scalable solution. Why not. To expensive and as such to high risk. The risk is due to the fact I don’t have one of these:

So storage vendors need to perform a delicate balancing act. It’s about price, value, technology evolution, rapid adoption, diversification, integration, assimilation & licensing models in a good enough is good enough world where the solution needs to deliver from day one.

I for one will be very interested if all storage vendors can deliver enough value to retain the mid market or if they’ll become top feeders only. The push to the cloud, the advancements in data replication & protection in the application and platform layer are shaking up the traditional storage world. Combine that with the fast pace at which SSD & Flash storage are evolving together with Windows Server 2012 that has morphed into a very capable storage platform and the landscape looks very volatile for the years to come. Think about  ever more solutions at the application (Exchange, SQL server) and platform layer (Hyper-V replica) with orchestration on premise and/or in the cloud and the pressure is really on.

So how do you choose a solution in this environment?

Whenever you are buying storage the following will happen. Vendors, resellers & sales people, are going to start pulling at you. Now, some are way better than others at this, some are even down right good at this whole process a proceed very intelligently.

Sometimes it involves FUD, doom & gloom combined with predictions of data loss & corruption by what seem to be prophets of disaster. Good thing is when you buy whatever they are selling that day, they can save you from that. The thing is this changes with the profit margin and kickbacks they are getting. Sometimes you can attribute this to the time limited value of technology, things evolve and todays best is not tomorrows best. But some of them are chasing the proverbial $ so hard they portray themselves as untrustworthy fools.

That’s why I’m not to fond of the real big $ projects. Too much politics & sales. Sure you can have people take care of but you are the only one there to look out for your own interests. To do that all you need to do is your own due diligence and be brave. Look, a lot of SAN resellers have never ever run a SAN, servers, Hyper-V clusters, virtualized SQL Server environments or VDI solutions in your real live production environments for a sustained period of time. You have. You are the one whose needs it’s all about as you will have to live and work with the solution for years to come.  We did this exercise and it was worth while. We got the best value for money looking out for our own interests.

Try this with a reseller or vendor. Ask them about how their hardware VSS providers & snapshot software deals with the intricacies of CSV 2.0 in a Hyper-V cluster. Ask them how it works and tell them you need to references to speak to who are running this in production. Also make sure you find your own references. You can, it’s a big world out there and it’s a fun exercise to watch their reactions Winking smile

As Aidan remarked in his blog on ODX–Not All SANs Are Created Equally

These comparisons reaffirm what you should probably know: don’t trust the whitepapers, brochures, or sales-speak from a manufacturer.  Evidently not all features are created equally.

You really have to do your own due diligence. Some companies can afford the time, expense & personnel to have the shortlisted vendors deliver a system for them to test. Costs & effort rise fast if you need to get a setup that’s comparable to the production environment. You need to device tests that mimic real life scenario’s in storage capacity, IOPS, read/write patterns and make sure you don’t have bottleneck outside of the storage system in the lab.

Even for those that can, this is a hard thing to do. Some vendors also offer labs at their Tech Centers or Solutions Centers where customers or potential customers can try out scenarios. No matter what options you have, you’ll realize that this takes a lot of effort. So what do I do? I always start early. You won’t have all the information, question & answers available with a few hours of browsing the internet & reading some brochures. You’ll also notice that’s there’s always something else to deal with or do, so give your self time, but don’t procrastinate. I did visit the Tech Centers & Solution Centers in Europe of short listed vendors. Next to that I did a lot of reading, asked questions and talked to a lot of people about their view and experiences with storage. Don’t just talk to the vendors or resellers. I talked a lot with people in my network, at conferences and in the community. I even tracked down owners of the shortlisted systems and asked to talk to them. All this was part of my litmus test of the offered storage solutions. While perfection is not of this world there is a significant difference between vendor’s claims and the reality in the field. Our goal was to find the best solution for our needs based on price/value and who’s capabilities & usability & support excellence materialized with the biggest possible majority of customers in the field.

Friendly Advice To Vendors

So while the entire marketing and sales process is important for a vendor I’d like to remind all of them of a simple fact. Delivering what you sell makes for very happy customers who’s simple stories of their experiences with the products will sell it by worth of mouth. Those people can afford to talk about the imperfections & some vNext wishes they have. That’s great as those might be important to you but you’ll be able to see if they are happy with their choice and they’ll tell you why.

DELL PowerEdge VRTX Has Potential Beyond ROBO As a Scale Out File Server Building Block

The PowerEdge VRTX

I went to have a chat with Dell at TechEd 2013 Europe in Madrid. The VRTX was launched during DELL Enterprise Forum early June 2013 this concept packs a punch and I encourage you to go look at the VRTX (pronounced as “Vertex”) in more detail here. It’s a very quite setup which can be hooked up to standard power. Pretty energy efficient when you consider the power of the VRTX. And the entire setup surely packs a lot of punch at an attractive price point.

It can serve perfectly for Remote Office / Branch Office (ROBO) deployments but has many more use cases as it’s very versatile. In my humble opinion DELL’s latest form factor could be used for some very nice scale out scenarios. It’s near perfect for a Windows Server 2012 Scale Out File Server (SOFS) building block. While smaller ones can be build using 1Gbps the future just needs 10Gbps networking.

10Gbps, RDMA (iWarp, RoCE)

That’s the first thing I missed and the first thing I was told that would arrive very soon. So I’m  very happy with that. With sufficient 10Gbps ports to servers and  iWarp or RoCE RDMA capable NICs (there’s cheap enough compared to ordinary 10Gbps cards not to have to leave that capability out) we have all we need to function as powerful building block for the Scale Out File Server model with Windows Server 2012 (R2) where the CSV network becomes the storage network leveraging redirected IO. For this concept look at this picture from a presentation a year ago. SMB 3.0 Multichannel and RDMA make this possible.

While then I drew the SOFS building blocks out of R720 7 & MD1200  hardware, the VRTX could fit in there perfectly!

Storage Options

Today DELL uses their implementation of Clustered PCI Raid for shared storage which is supported since Windows Server 2012. This is great. For the moment it’s a non redundant setup but a redundant one is in the works I’m told. Nice, but think positive, redirected IO  (block level) over SMB 3.0 would save our storage IO even today. It would be a very wise and great addition to the capabilities of this building block to add the option & support for Storage Spaces. This would make the Scale Out File Server concept shine with the VRTX.

Why? Well I would give us following benefits in the storage layer and the VHDX format in Hyper-V can take benefits :

  • Deduplication
  • Thin Provisioning
  • Management Delegation
  • UNMAP
  • Write Cache
  • Full benefits of ReFS on storage spaces for data protection
  • Automatic Data Tiering with commodity SSD (ever cheaper & bigger) and SAS disks perhaps even the Near Line ones (less power & cooling, great capacity)
  • Potential for JBOD redundancy

Look at that feature set people, in box, delivered by Windows. Sweet! Combine this with 10Gbps networking and DELL has not only a SOFS building block in their port folio, it also offers significant storage features in this package. I for one would like them to do so and not miss out on this opportunity to offer even more capabilities in an attractive price package. Dell could be the very first OEM to grab this new market opportunity by supporting the scale out approach and out maneuver their competitors

Anything Else?

Combine such a building block as described above with their unmatched logistical force for distribution and support this will be a hit a a prime choice for Windows shops. They already have the 10Gbps networking gear & features (DCB) in the PowerConnect 81XX & Force10 S4810 switches. It could be an unbeatable price / capabilities / feature combo that would sell very well.

If we go for SOFS we might need more storage in a single building block with a 4 node cluster. Extensibility might be nice for this. More not just as in capacity but I need to work out the IOPS the available configurations can give us.

MVP Carsten Rachfahl Visits & Interviews Me On Networking & Storage in Windows Server 2012

Last month Carsten (MVP – Virtual Machine) & Kerstin Rachfahl (MVP – Office 365) visited me in my home town. Apart from a short visit to the historic center & a sushi diner amongst friends we also did an interview where we discussed our ongoing Windows Server 2012 Hyper-V activities. We’re trying to leverage as much of the product we can to get the best TCO & ROI and as early adopters we’ve been reaping the benefits form the day the RTM bits were available to us. So far that has been delivering great results. Funny to hear me mention the Fast Track designs as a week later we saw version 3 of those at MMS2013. The most interesting to me about those was the fact that the small & medium sizes focus on Cluster in a Box and Storage Spaces!

While we were having fun talking about the above we also enjoyed some of the most beautiful landmarks of the City of Ghent as a back drop for the interview. It was filmed in a meeting room at AGIV, to whom I provide Infrastructure services with a great team of colleagues. Just click the picture to view the video.

You can also enjoy the video on Carsten’s blog http://www.hyper-v-server.de/videos/interview-mit-didier-van-hoye-ber-seinen-storage-netwerk-und-mehr/ All I need to do now is to arrange for Carsten to physically touch the Compellent storage I think.

Saying Goodbye To Old Hardware Responsibly

Last year we renewed our SAN storage and our backup systems. They had been serving us for 5 years and where truly end of life as both technologies uses are functionally obsolete in the current era of virtualization and private clouds. The timing was fortunate as we would have been limited in our Windows 2012, Hyper-V & disaster recovery plans if we had to keep it going for another couple of years.

Now any time you dispose of old hardware it’s a good idea to wipe the data securely to a decent standard such as DoD 5220.22-M. This holds true whether it’s a laptop, a printer or a storage system.

We did the following:

  • Un-initialize the SAN/VLS
  • Reinitialize the SAN/VLS
  • Un-initialize the SAN/VLS
  • Swap a lot of disks around between SAN/VLS and disk bays in a random fashion
  • Un-initialize the SAN/VLS
  • Create new (Mirrored) LUNS, as large as possible.
  • Mounted them to a host or host
  • Run the DoD grade  disk wiping software against them.
  • That process is completely automatic and foes faster than we were led to believe, so it was not really such a pain to do in the end. Just let it run for a week 24/7 and you’ll wipe a whole lot of data. There is no need to sit and watch progress counters.
  • Un-initialize the SAN/VLS
  • Have it removed by a certified company that assures proper disposal

We would have loved to take it to a shooting range and blast the hell of of those things but alas, that’s not very practical Smile nor feasible Sad smile. It would have been very therapeutic for the IT Ops guys who’ve been baby sitting the ever faster failing VLS hardware over the last years.

Here’s some pictures of the decommissioned systems. Below are the two old VLS backup systems, broken down and removed from the data center waiting disposal. It’s cheap commodity hardware with a reliability problem when over 3 years old and way to expensive for what is. Especially for up and out scaling later in the life time cycle, it’s just madness. Not to mention that those thing gave us more issues the the physical tape library (those still have a valid a viable role to play when used for the correct purposes). Anyway I consider this to have been my biggest technology choice mistake ever. If you want to read more about that go to Why I’m No Fan Of Virtual Tape Librariesimageimage

To see what replaced this with great success go to Disk to Disk Backup Solution with Windows Server 2012 & Commodity DELL Hardware – Part II

The old EVA 8000 SANs are awaiting removal in the junk yard area of the data center. They served us well and we’ve been early customers & loyal ones. But the platform was as dead as a dodo long before HP wanted to even admit to that. It took them quite a while to get the 3Par ready for the same market segment and I expect that cost them some sales. They’re ready today, they were not 24-12 months ago. image

So they’ve been replaced with Compellent SANs. You can read some info on this on previous blogs Multi Site SAN Storage & Windows Server 2012 Hyper-V Efforts Under Way and Migration LUNs to your Compellent SAN

The next years the storage wares will rage and the landscape will change a lot. But We’re out of the storm for now. We’ll leverage what we got Smile. One tip for all storage vendors. Start listening to your SME customers a lot more than you do now and getting the features they need into their hands. There are only so many big enterprises so until we’re all 100% cloudified, don’t ignore us, as together we buy a lot of stuff to. Many SMEs are interested in more optimal & richer support for their windows environments if you can deliver that you’ll see your sales rise. Keep commodity components, keep building blocks and from factors but don’t use a cookie cutter to determine our needs or “sell” us needs we don’t have. Time to market & open communication is important here. We really do keep an eye on technologies so it’s bad to come late to the party.
