  • Some say DAS is best.
  • Some say keep the storage in the servers.
  • Some say you should build your own shared array.

But when it comes to Microsoft environments, it often helps to have independent experts investigate the matter to get a fresh perspective.

In a recent study, Wikibon determined that a shared storage infrastructure (powered by EMC’s next generation VNX2 storage systems) can match the prices offered by Office 365 public cloud and offer more capabilities, more security, and more control.

This, however, assumes a completely consolidated approach for deploying multiple mixed workloads such as Exchange, SharePoint, SQL Server, Lync – where the VNX2 really shines.   We use FAST VP, FAST Cache, and a combination of drive types to achieve the best balance of performance and cost.

EMC’s VNX = Award Winning storage for Microsoft environments

Microsoft’s TechEd 2013 is next week, and I’m looking forward to spending time with my longtime industry friends and making some new connections on the show floor in New Orleans.

This year, I’ll attend as part of the Unified Storage Division, and felt I needed to share a little about the success of VNX and VNXe arrays into Microsoft environments:

awards

EMC’s VNX Unified Storage Platform has been recognized with awards from a slew of independent analysts such as Gartner, IDC and Wikibon, as well as media publications such as ComputerWorld, CRN and Virtualization Review due to the ability of the VNX family to power mission critical applications, integrate with virtual environments and solve SMB IT challenges, among other accolades.   We take pride in being the #1 storage for most Microsoft Windows-based applications.

BUT… DOES  MICROSOFT WINDOWS NEED A SAN?  CAN’T WE DO IT OURSELVES?

Well, after speaking with Windows Server 2012, SQL Server, and EMC customers, partners and employees, the independent analyst firm Wikibon posted a before and after comparison model based on an enterprise customer environment. The idea is that the total cost of bolting together your own solution isn’t worth it.

wikibon-windows-study

The findings showed that by moving a physical, non-tiered environment to a virtualized environment with flash and tiered storage SQL Server customers realized a 30% lower overall TCO over a 3 year period including hardware, software, maintenance, and management costs for their database infrastructure.

The graphic shows that a do-it-yourself approach saves very little if anything in hardware costs and will divert operational effort to build and maintain the infrastructure. Risks and costs are likely to be higher with this approach.

In the end, EMC’s VNX infrastructure was proven to deliver a lower cost and lower risk solution for Windows 2012 versus a direct-attached storage (DAS) or JBOD (just a bunch of disk) model.  Full study here.

Video of EMC’s Adrian Simays and Wikibon Analysts discussing these results is here on YouTube.

MICROSOFT INTEGRATIONS AND INNOVATIONS  

EMC’s VNX platform considers Microsoft applications, databases, and file shares to our sweet spot as evidenced by our early integration of the latest Windows Server 2012 features that increase performance, efficiency, availability, and simplicity for our joint customers.

Performance, Efficiency, Availability, Simplicity

1. Performance

Within Windows, we were the first storage array to support SMB 3 and ODX Copy Offload (part of SMB 3) to enable large file copies over SAN instead of consuming network bandwidth and host CPU cycles.

ODX-impact

This test highlights the speed difference before (left) and after (right) ODX was implemented. With EMC VNX and ODX enabled, you can accelerate your VM copies by a factor of 7 while reducing server CPU utilization by a factor of 30!

For applications and databases, VNX FAST Cache and FASTVP automatically tunes your storage to match your workload requirements saving up to 80% of the time it would take to manually balance workloads.

The Enterprise Storage Group (ESG) Lab confirmed that a data warehouse solution with Windows Server 2012 with Hyper-V, Microsoft SQL Server 2012 with new Columnstore indexing, and VNX FAST technologies and VNX storage form a complete solution to meet the business requirements of mid-tier organizations and beyond. An 800GB DW was deployed which is fairly typical for a medium sized business. With EMC FAST enabled, throughput reached up to 379 MB/sec, showing over 100% improvement over SQL Server 2012’s baseline Rowstore indexing. The DSS performance workload with EMC FAST enabled completed up to nine times faster than with rowstore indexing.

2. Efficiency

IT managers and storage administrators frequently adopt well-known forecasting models to pre-allocate storage space according to the storage demand growth rate. The main challenge is how to pre-allocate just enough storage capacity for the application. Reports from many storage array vendors indicate that 31% to 50% of the allocated storage is either stranded or unused. Thus, 31% to 50% of the capital investment from the initial storage installment is wasted.

The VNX supports Windows host-level and built-in storage-level thin provisioning to drastically reduce initial disk requirements.  Windows Server 2012 provides the ability to detect thin-provisioned storage on EMC storage arrays and reclaim unused space once it is freed by Hyper-V. In the previous scenario, an ODX-aware host connected to an EMC intelligent storage array would automatically reclaim the 10 GB of storage and return it to the pool where it could be used by other applications.

Furthermore, for application storage we partner with companies like Kroll and Metalogix to provide better solutions for Exchange single item recovery and SharePoint remote BLOB storage which can reduce SQL stored SharePoint objects by about 80-90% and improve SQL Respnse times by 20-40%

3. Availability

Our first to market integration with SMB3 not only provides for performance improvements, it also enables SMB 3 Continuous Availability allowing applications to run on clustered volumes with failovers that are transparent to end users.  For example, SQL Server may store system tables on the file shares such that any disruptive event to the access of the file share can lead to interruption of SQL Server operation. Continuous Availability is accomplished via cluster failover on the host side and Data Mover of Shared Folder failover on the VNX side.

Other SMB 3.0 Features supported include:

  • Multi-Channel / Multipath I/O (MPIO ) – Multiple TCP connections can now be associated with a single SMB 3.0 session and a client application can use several connections to transfer I/O on a CIFS share.  This optimizes bandwidth and enables failover and load balancing with multiple NICs.
  • Offload Copy - Copying data   within the same Data Mover can now be offloaded to the storage which reduces the workload on the client and network.
  • SMB Encryption - Provides secure access to data on CIFS shares, protecting data on untrusted networks and providing end-to-end encryption of data in- flight.
  • Directory Lease – SMB2   introduced a directory cache which allowed clients to cache a directory listing to save network bandwidth but it would not see new updates.  SMB3 introduces a directory lease and the client is now automatically aware of changes made in a cached directory.
  • Remote Volume Shadow Copy Service (RVSS) – With RVSS, point-in-time snapshots can be taken across multiple CIFS shares, providing improved performance in backup and restore.
  • BranchCache – Caching solution to have business data in local cache. Main use case is remote office and branch office storage.

EMC also offers a wide range of application availability and protection solutions that are built into the VNX including snapshots, remote replication, and a new RecoverPoint virtual replication appliance.

4. Simplicity

When it comes to provisioning storage for their applications, admins often have to navigate through too many repetitive tasks requiring them to touch different UIs and increasing the risk of human error. Admins also likely need to coordinate with other administrators each time they need to provision space. This is not very efficient. Take for example a user that wants to provision space for SharePoint. You need to work with Unisphere to create a LUN and add it to a storage group. Next you need to log onto the server and run disk manager to import the volume. Next you need to work with Hyper-V, then SQL Server Mgmt Studio, then SharePoint Central Admin. A bit tedious to say the least.

esi

EMC Storage Integrator (ESI) on the other hand streamlines everything we just talked about. Forget about how much faster it actually is… Just think about the convenience and elegance of this workflow compared to the manual steps outlined in our last paragraph. ESI is a free MMC based download that takes provisioning all the way into Microsoft Applications. Currently only SharePoint is supported but SQL and Exchange wizards are coming soon. This is a feature that surprises and delights our customers!

 SO WHAT DO VNX CUSTOMERS SAY?

EMC’s VNX not only provides a rock solid core infrastructure foundation, but also delivers significant features and benefits for application owners and DBAs.     Here’s some quotes from customers who have transformed their Microsoft environments using the VNX and VNXe platforms.

Peter Syngh Senior Manager, IT Operations, Toronto District School Board

 “EMC’s VNX unified storage has the best of everything at a very cost-effective price. It integrates with Microsoft Hyper-V, which is crucial to our cloud strategy, and with its higher performance, automated tiering and thin provisioning, VNX was a no-brainer.”

Marshall Bose Manager of IT Operations, Ensco (Oil/Gas)

 “A prime reason for choosing EMC over NetApp was that VNX is such a great fit for virtualization. With all the automation tools and tight integration with VMware, VNX is far easier than NetApp when it comes to spinning up and managing virtual machines.”

Rocco Hoffmann, IT Architect BNP Paribas (German Bank)

“We are achieving significant savings in energy and rack space. In fact our VNX requires only half the rack space and has reduced our power and cooling costs”

Charles Rosse, Systems Administrator II Baptist Memorial Health Care

“Since the VNX has been built into the design of our VDI from the beginning, it can easily accommodate growth- all we need to do is to plug in another drive or tray of drives and we get incrementally better performance.”

Erich Becker,  Director of Information Systems, AeroSpec (Manufacturing)

“…We loved the fact that VNXe and VMware worked extremely well together …we have dramatically cut operating costs, increased reliability and data access is now twice as fast as before.”

BOTTOM LINE

There are many more customers that have given praise to the VNX Family for powering their Microsoft applications but I don’t have the room to put them all in.     EMC is a trusted brand in storage, and the VNX today is an outstanding unified platform which successfully balances our customers block and file needs for their Microsoft file and application data – and gets awards for it.    Feel free to find out more about the VNX and VNXe product lines here and here.

Also come talk to us next week at TechEd, we will be there to help customers and partners learn more about our technology.

So much to understand about your Cloud Options for Microsoft Applications …The path you take matters! The Radicati Group Perspective

In the world of IT…. things are moving very quickly.  In my role at EMC, I have the opportunity and quite frankly privilege, to talk to many customers, partners, press and analysts and as well as EMC’s many experts on Microsoft.  Consistently I hear from all about the abundance of information out there on cloud computing and virtualization… and how confusing it can be to cut through all of the noise and truly educate yourself.   

There are a number of EMC resources and  sponsored opportunities for IT professionals to do just that –  educate themselves on technical considerations for deploying Microsoft Applications such as Exchange, SharePoint, SQL Server database and Windows Server in a cloud environment.  

EMC recently worked with industry leading analysts and thought leaders  to discuss what customers should begin to think about as they evaluate which path to take regarding their Microsoft applications and cloud computing.  I am going to be posting a weekly blog on our efforts to help our customers, partners and  the broader  Microsoft community on the role that infrastructure can have in helping your transform your Microsoft environments to the Cloud.

As always – key place to start your education process is here on this blog and also on our Everything Microsoft Community on ECN.

Whats in your SLA?

People have been considering and comparing public (hosted) and private (on-premises) cloud solutions for some time in the messaging world, and at increasing rates for database and other application workloads.  I’m often surprised at how many people either don’t know the contents and implication of their service provider service level agreement (SLA), or fail to adjust the architecture of private cloud solution and then directly compare cost. 

Here are my five lessons for evaluating SAAS, PAAS, and IAAS provider SLAs:

Lesson 1: Make sure that what’s important to you is covered in the SLA

Lesson 2: Make sure that the availability guarantee is what you require of the service

Lesson 3: Evaluate the gap between a service outage’s cost to business and the financial relief from the provider

Lesson 4: Architect public and private clouds to the similar levels of availability for cost estimate purposes

Lesson 5: Layer availability features onto private clouds for business requirement purposes

I’ll use the Office 365 SLA to explore this topic – not because I want to pick on Microsoft,  but because it’s a very typical SLA, and one of the services it offers (email) is so universal that it’s easy to translate the SLA’s components into the business value that you’re purchasing from them.

Defining availability

The math is simple.  It’s a 99% uptime guarantee with a periodicity of one month:

image

If that number falls below 99, then they have not met their guarantee.  For what it’s worth, during a 30 day month, the limit will be about 44 minutes of downtime before they enter the penalty, or about 8.7 hours per year.

But what does “Downtime” mean?  Well, it’s stated clearly for each service.  This is the definition of downtime for Exchange Online:

“Any period of time when end users are unable to send or receive email with Outlook Web Access.”

Here’s what’s missing:

  • Data:  The mailbox can be completely empty of email the user has previously sent and received.  In fact the email can disappear as soon as they receive it.  As long they can log in via OWA, the service is considered to be “up”.
  • Clients:  Fat outlook, blackberry, and Exchange ActiveSync (iPhone/iPad/Winmopho, and most Android) clients are not covered in any way under the SLA

Lesson 1: Make sure that what’s important to you is covered in the SLA

Lesson 2: Make sure that the availability guarantee is what you require of the service

Balancing SLA penalties with business impact

My Internet service is important to me.  When it’s down, I lose more productivity than the $1/day or so I spend on it.  Likewise, email services are probably worth more than the $8/month/user or so that you might pay your provider for it.  That doesn’t mean that you should spend more than you need for email services.  But it does mean that if you do suffer an extended or widespread outage, there will likely be a large gap between the productivity cost of the downtime and the financial relief you’ll see in the form of free services you’ll see from the provider. 

image

Callahan Auto Parts also offers a guarantee

I’ll put this in real numbers.  Let’s say I have a 200 person organization.  I might pay $1600/month for email services from a provider.  If my email is down for a day during the month, my organization experiences 96% uptime for that month, and as a result, my organization is entitled to a month of free email from the provider, worth about $800.

image

The actual cost of my downtime will very likely exceed $800.  To calculate that cost we need the number of employees, the loaded cost per hour for the average employee, and and the productivity cost of the loss of email services.  For our example of 200 employees, let’s imagine a $50/hour average loaded cost to business and a 25% loss of productivity when email is down:

200 employees x $50 cost per hour x .75 productivity rate x 8 hour outage = $60,000 of lost productivity

Subtract the $800 in free services the organization will receive the next month, and the organization’s liability is $59,200 for that outage.

Now how do you fill that gap?  I’m not entirely sure.  It could be just the risk of doing business – after all, the business would just absorb that cost if they were hosting email internally and suffered an outage.  If the risk and impact were large enough, I would probably seek to hedge against it – exploring options to bring services in house quickly, or even looking to an insurance company to defray the cost of outages – if Merv Hughes can insure his mustache for $370,000, then surely you can insure the availability of your IT services.  Regardless, it’s wise not to confuse a “financially backed guarantee” with actual insurance or assurance against outage.

File Photo:  What a $370k mustache may look like.  Strong.

Lesson 3: Evaluate the gap between a service outage’s cost to business and the financial relief from the provider

Comparing Apples to Oranges

image

See what I did there?

Doing a cost comparison between public cloud designed to deliver 99.9% availability and a private cloud designed to provide 99.99% or 99.999% availability makes little sense, but I see people do it very frequently.  Usually it’s because the internal IT group’s mandate is to “make it as highly available as possible within the budget”.  So I’ll see a private cloud solution with redundancy at every level, capabilities to quickly recover from logical corruption, and automated failover between sites in the event of a regional failure, compared to a public cloud solution that provides nothing but a slim guarantee of 99.9% availability.  In this instance, it’s obvious why the public cloud provider is less expensive, even without factoring in efficiencies of scale.

To illustrate this, I usually refer to Maslow’s hand-dandy Hierarchy of Needs, customized for IT high availability.

image image

Single Site and Multi-site Hierarchies of Need

If I want to make an accurate comparison between a public cloud provider’s service and pricing and what I can do internally, I often have to strip out a lot of the services that are normally delivered internally.  Here’s the steps:

  1. Architect for equivalence.  If I have a public cloud provider just offering 3 9’s and no option for site to site failover, for my database services, I might just do a standalone database server.  Maybe I’d add a cheap rapid recovery solution (like snapshots or clones) to hedge against compete storage failure and cluster at the hypervisor layer to provide some level of hardware redundancy.  If my cloud provider offers disaster recovery, I’d figure out what their target RPO/RTO and insert some solution that matches that capability.
  2. Do a baseline price comparison.  Once I’ve got similar solutions to compare, I can compare price.  We’ll call this the price of entry.
  3. Add capabilities to the private cloud solution after the baseline.  I only start layering features that add availability and flexibility to the solution after I’ve obtained my baseline price.  Only then can I illustrate the true cost of those features, and compare them to the business benefits.

Lesson 4: Architect public and private clouds to the same levels of availability for cost estimate purposes

Lesson 5: Layer availability features onto private clouds for business requirement purposes
