Application Protection: There’s Something Happening Here

There’s something happening here
What it is ain’t exactly clear
There’s a man with a gun over there
Telling me I got to beware

Yes, it’s blasphemy to simply change a classic like Buffalo Springfield’s “For What’s It Worth” – but I will anyway to prove my point.

There’s something happening here

If you haven’t noticed, IT is changing rapidly. Just search for IT transformation, IT as a Service, and converged infrastructure to see how far we’ve come in only the past few years.  This industry moves!

What it is ain’t exactly clear

We know a Cloud is built differently, operated differently, and consumed differently. So we know companies have begun re-architecting IT in order to offer more of a service in order to react faster to meet user needs. They know they must change their operational models and in many cases their organizational structure. They might also seek converged infrastructures to get moving faster.    But… has protection changed to keep pace with this transformation?

There’s a man with a gun over there
Telling me I got to beware

It’s been said that in the song the gun is more of a metaphor for the tension between groups within the US before Vietnam. And in a much less violent analogy, the tension between the IT team and the application owners has never been stronger.

The application teams want to have great performance and protection of their application. But they’ve never been empowered by the IT department to protect themselves with storage-level tools. The storage team wants to let them, but they fear they might create too many copies of their data. Instead, the app owners went out and used tools for their own application, creating their own protection strategy which might not deliver the best protection they can get.  To win back the hearts and minds of the application owners and DBA’s, the IT department and the storage teams need to get better at protecting applications as a service.

On the Road to Application Protection as a Service

Many companies have has attempted to do this in the past – with products that help you protect and restore your applications and critical virtual machines. They have tools that install on the server and can “freeze” and “thaw” the current transactions into the database, so that when a snapshot is taken, there is a clean copy that can be easily restored.  The major benefit of these tools is SPEED as the copy process is incremental and the restore process is also lightning fast.  Restoring a 1 TB database in minutes.

It needs to get easier. Like any “enterprise” tool, many of these products designed for snapshots and replication require a significant learning curve. We need something simple that integrates with the tools we know and love.

We should provide self-service capabilities. Instead of spending hours and hours making sure application owners are getting the protection they need, they should be empowered to simply protect and restore their own data.

We are driven by service levels. IT departments and storage teams need to offer “protection service catalogs” with various (e.g. Platinum, Gold, Silver, Bronze) levels of protection varied by RPO – from very low data loss (synchronous replication) to more sporadic application-consistent snapshots – all from one interface. This makes it easy for the app team and people with the checkbooks to really understand the value placed on the different applications in your catalog.

There truly is something happening here
And what is will be made clear at EMC World 2012!

Hope to see you there!

EMC PowerPath vs MPIO – Take the High Road

Guest post by Mark Prahl

If you live in New England like I do, you have experienced some of the wettest weather on record in recent times. And, if you live in an old town like I do dating back to before the American Revolution, you know that some of those old paved paths can get flooded and become impassible when the rain comes.

Well, if you’re using one of those data path solutions native to an operating system or hypervisor you can expect some limitations to the paths at your disposal. Most use a basic method like round robin which distributes I/O among all available data paths in sequence because it considers all paths to be equal.

Now, just imagine your data paths are roads and you’re in the northeast like I am. What do you do when a road is underwater? Keep traveling over the same road because that’s all you can do. I think not.  You might eventually get to your destination if you’re lucky, but you’re just as likely to arrive late or not at all.

Well, the same goes for multipathing software.

Want to deliver a clear way for your customers?  Want to ensure the best performance?   Take the high road and get EMC PowerPath Multipathing. Right out of the box, PowerPath will automatically select the right optimized data path algorithm for your data center environment.

The Enterprise Strategy Group recently compared PowerPath Multipathing with Windows native MPIO and showed the performance advantages of PowerPath in Windows environments.  Results ranged from about 20% to over 200% better performance with PowerPath depending on the application.

But don’t take my word for it. Read the report yourself!

Windows Geoclusters, Stretch-Clusters, and RecoverPoint/CE Failover

Taking a page out of Chief EMC Blogger Chuck Hollis‘ playbook, I’m attaching the graphics from entire PPT file that I thought would be important to highlight for this blog and its readers.  Some of the graphics didn’t fit to the page as well as I thought it would (I need to shrink them further). So if you like what you see, you can download the whole PPT right here: RecoverPointCE-MSfailoverclusterPPT

In a nutshell, EMC’s RecoverPoint/Cluster Enabler extends a Microsoft cluster across two sites.  A Microsoft cluster normally provides local site “HA” or high availability of server nodes, and RecoverPoint/CE adds “DR” or disaster recovery (AFTER) by stretching the second node to anywhere outside of your primary datacenter.  This presentation walks you through the basics behind that simple idea and provides some additional background.   Slide building credit goes to Gary Archer, a great guy who is always keeping me sharp on RecoverPoint’s latest features.

Recovery Time Objective: Targeted amount of time to restart a business service after a disaster event

Recovery Point Objective: Amount of data lost from failure, measured as the amount of time from a disaster event

Various approaches for DR and their RTO rankings

Microsoft Failover Clusters (formerly MSCS (or Wolfpack if you go back really far)) provides local HA, not DR across a site.  For this, you need to S-T-R-E-T-C-H your cluster. EMC’s Cluster Enabler is one way to do it, and using RecoverPoint with it would be like have your iPhone on Verizon.  Not the best analogy, but you get my point I hope!

Basic requirements – use SYNCHRONOUS or ASYNCHRONOUS - distance is not the issue but 400 ms latency ASYNC and 4 ms latency SYNC

Leverages majority node set clustering.    If you have 2 nodes/servers on Site A and 2 nodes/servers on Site B you will need a “tiebreaker” for deciding how to remain online after a failure – most common method for this tiebreaker is File Share Witness.  Many articles can give you additional background on majority node set clustering – it’s a good thing to know – I will point you to the blog from an old friend of mine John Toner, who writes about geographically dispersed clusters.

The architecture. 

What each piece does:  CE is a filter driver that “catches” Microsoft Cluster failure events and let’s the RecoverPoint-managed disk systems know to failover as appropriate.  Very sophisticated logic is built-in to prevent cluster split-brain – scenarios where the link is down and the application (such as a SQL server database) doesn’t know what is the correct owner of the disk resources.

See if you see what is happening above – AUTOMATIC FAILOVER.

Integrates with and supports Hyper-V

Works with latest features like Live Migration – so you can Live Migrate workloads locally for HA and failover remotely for DR.  You can control if you want to failover locally before failing over across a site.

Self explanatory – the failover steps in detail.

More detail of Live Migration support – note synchronous requirement.

Multi-array support.  We can create consistency groups with storage devices from multiple arrays in the same group.  This allows fora lot of interesting failover implementations (failover locally first, not remotely for example) and lets you keep components grouped together… like an entire SharePoint farm.

Hey, it works with Oracle on Windows too.

Recap of the benefits – hopefully it makes sense and it’s the reason that customers love this integration – with RecoverPoint/CE you get more control, less bandwidth required (3-12x savings on bandwidth as reported by RP customers), and it’s integrated with Microsoft Clusters to enable seamless failover.

Now that is a cool product.


Cool Infographic Poster for Hyper-V

Step 1.  Download large infographic poster here (or click on the picture). Hat tip to Techhead for sharing this one.

Step 2.  Find a BAP (Big A–* Printer)

This thing is 40 inches by 25 inches!

Maybe send it to your local photo developer or print shop.

Or maybe just download the PDF and keep it handy.

I love graphics that have an insane amount of detail embedded into them!
