Ins and Outs of IOPS - New VKernel White Paper by Brad Bonn

Strengths and weaknesses of using IOPS as a measure of storage performance

files/blog/Brad Bonn Headshot.pngIn his most recent white paper "Ins and Outs of IOPS", VKernel Senior Systems Engineer Brad Bonn discusses the strengths and weaknesses of using IOPS as a measure of storage performance.  

In Brad's experience, disk performance seems to have traditionally been measured in how many acronyms you could list as present in a solution.  In filling the need for better metrics on storage performance, IOPS has become a commonplace term in determining shared storage capabilities.  In this white paper, Brad discusses the benefits and pitfalls of focusing on IOPS, and how storage I/O is an often over-simplified topic.  He provides a deep dive into:

  • Shared storage fundamentals
  • Links in the chain of storage
  • IOPS as a measurement of disc I/O
  • Making the most of IOPS

Download the free white paper here and when you're done share your thoughts and comments with us.  We'd like to hear them.

Enjoy!

Cloud Connect - Pricing Strategies for Private Clouds

Thursday, February 16, 2012 | by Bryan Semple | (comments: 0)

I had the pleasure of speaking at Cloud Connect in Santa Clara on Tuesday. Topic of the presentation was “Pricing Strategies for Private Clouds." The track was moderated by Lauren E. Nelson, a Researcher from Forrester Research. The talk focused on private cloud pricing not public, and pricing, not charging. Charging is another can of worms requiring chargeback systems, integration with financial systems, etc.

A video of the presentation can be seen here:

Building a Pricing Model for Private Clouds

The white paper "Setting Prices for Private Clouds" the presentation was based on can be downloaded here.

Some observations and updates from the talk. The audience was composed of vendors but also some IT professionals running hard core private clouds. In general, the five reasons for pricing private clouds we discussed were:

  1. Budgeting
  2. Reduce waste and over allocation
  3. Drive IT to operate as a business
  4. Enable open market competition 

Walking through these reasons, there was general agreement from the audience that waste reduction is a critical component of this process, if not the most important. Pricing out private cloud services was also important for getting funding to reinvest and grow the cloud environment.

Walking through the pricing triangle of cost, competitors, and value yielded a lively discussion. From a cost standpoint:

  • One IT administrator reported that public cloud providers where unable to provide a competitive bid for their 85,000 seat email environment
  • A second IT administrator reported that for test and development, their $1M price tag was easily beaten in both time to stage and cost ($3,000) offered by a public provider

There appeared to be general agreement that from a cost standpoint, test and development worked for public clouds. When we discussed competitive pricing and value, one administrator was quick to point out that the public cloud providers are not his “competition”. Rather, he sees IT as the broker for services.

From a value standpoint, the top value issues internal IT provided over public clouds were:

  • Customization
  • Reliability
  • Support for home grow applications
  • Security
  • Compliance
  • Performance and latency 

The reliability comment surprised me. We spent some time discussing it and the general experience was that internal IT is still more reliable than public cloud providers.

We embarked on a lively discussion as to whether IT’s customers appreciated these value points. The results were mixed. But the lack of this appreciation for IT’s value added services was core to internal customers seeking out public cloud providers.

The most controversial part of the presentation was the recommendation on whether to reveal actual prices of cloud services to internal IT customers. My premise, that unless the goal of pricing IT services was to compete with external providers, avoiding the direct comparison was the best route. In other words, price cloud services as a loss leader since the value to the corporation of a customer using internal systems is higher than the value to end IT customer.

Cloud Connect was an enjoyable experience. To the audience, thank you for participating and providing new ideas on this topic.

3 Storage Topics You Should Read About This Week

Monday, February 13, 2012 | by Jonathan Klick | (comments: 0)

Virtualization Week in Review

The most costly part of our virtual infrastructures - storage - seems to be a popular theme this week. Here's what you should know:

Storage DRS (SDRS)

As more of us make plans to move over to vSphere 5, Frank Denneman explores the coexistence of SDRS and auto-tiering. Frank's partner in crime, Duncan Epping, shows us how to allow SDRS to spread VMs with multiple VMDKs across multiple datastores.

Server-Based Storage Tiering

As growing amounts of virtual servers and desktops continue to increase SAN and network workloads, EMC strives to improve storage performance by releasing VFcache, a server-based SSD solution. Chad Sakac shares his excitement and provides some details about VFcache. Others ask, "Is server-based storage tiering right for you?"

Cloud Storage

While I fish around for storage deals, Amazon defies Thailand and decreases its cloud storage prices by 12%. Red Hat piggybacks off the Amazon announcement and releases its Virtual Storage Appliance for Amazon AWS. Google feels its cloud isn't big enough and prepares to launch it's own cloud storage solution. However, I'd be very surprised - and impressed - if they were able to replace the little Dropbox icon in my notification tray.


Happy Monday!
