Dutch StorageExpo Recap

Earlier this week I had the pleasure of presenting a keynote talk (“Storage Industry Trends and Perspectives: Beyond Hype and Green Washing”) at the Dutch StorageExpo (produced by VNU Exhibitions Europe) event in Utrecht the Netherlands which was co-located in the ultra large Jaarbeurs congress center (e.g. convention center) along with concurrent shows for Linux, Security and networking making for a huge show and exhibition, almost a mini scaled down version of cebit or VMworld or EMCworld like event.

Dutch StorageExpo

Congratulations and many thanks to Marloes van den Berg of VNU Exhibitions and her team who put together a fantastic and well attended event, not to mention their warm and gracious Dutch hospitality.

European shows and events are different than those in the U.S. in that at European events, the focus is more on meeting, building and maintaining relationships and less on “Uui Gui” demos or marketing sales pitches involving complex demos and technology displays found at many U.S. events.

Granted, their are indeed product demos and technology to look at and talk about, and rest assured, the conversations and discussions when involving technology get right to the point and often much more direct. There is also a more relaxed aspect as seen in the many booths or stands as they are called, many of which have bars that serve up coffee in the morning as well as snacks and other beverages (the Hienken in Holland is much better than what is shipped to the U.S.) over which to discuss and have conversations about various topics, issues and technolgies.

Many of the issues being faced by the Europeans are similar to those being faced by IT organizations in North America as well as elsewhere in the world including limits or issues around power, cooling, floor-space footprints, economics, doing more with less to boost productivity and enhance efficieinecy while sustaining business growth without impacting service delivery or service levels. BC/DR, data proteciton and data security, virtualizaiton were all topics of interest and points of discussions among others.

I had the opportunity to meet several new people both from IT organizations, vars or resellers, consultants, vendors and media along with putting a face to a name of people I had meet virtually in the past not to mention re-connect with others that I have known from the past whom it was great to have had a chance to re-connect with.

Thanks to all of those who attended both the key note session on Wednesday afternoon as well as to those who were at Monday’s all day seminar organized by Gert Brouwer or Brouwer consultancy in Nijkerk, I really enjoyed the conversations and perspectives of everyone I had a chance to meet with this past week and look forward to future conversations.

CMG, Enabling “The Green and Virtual Data Center”

Storage I/O trends

Last week I was invited to by Tom Becchetti and the Minneapolis CMG folks to keynote at their session hosted at the Brocade facity in Minneapolis along with other speakers from Brocade, IBM, Teamquest and Sun.

The theme of my talk was “The Green and Virtual Data Center and The Importance of Metrics” which can be downloaded here.

I have been a member of CMG for many years as a former performance and capacity planning analyst when I worked in IT organizations and having presented at many CMG events around the world. While CMG has been around for many decades and has seen its share of ups and downs. With a current focus on boosting use, maximizing resource usage, improving service delivery and performance while using less energy in smaller footprints, now is the perfect opportunity for CMG to re-invent itself and show relevance as the organization that knows how to measure, watch, model and manage resource usage and service delivery effectiveness across different technology domains including servers, storage, networks, applications, operating systems and facilities. There is a golden opportunity for CMG members to step up and leverage their skills across different technology domains working with others to establish metrics, models and baselines.

In my new book, “The Green and Virtual Data Center” (Auerbach) I include a chapter on metrics and measurement as well as many other topics and themes that tie into the notion of effective and efficient data centers need to carry out Infrastructure Resource Management (IRM) which is also a chapter in the book, that includes performance and capacity planning across technology domains.

Watch for more on this topic.

Green Storage – Practical Ways to Reduce Power Consumption

Storage I/O trends

The busy 2008 fall events activities continue, last week was New Orleans at Arnauds and Chicago at Morton’s where the topic was BC/DR in and for virtualized environments in a series of dinner seminar events with IT professionals. This coming week it’s off to New York City and then Ceder Rapids Iowa. In New York City, I will be there to present at Storage Decisions on several topics including Green Storage – Practical Ways to Reduce Power Consumption on Tuesday, Clustered Storage – From SMB, to Scientific, to Social Networking and Web 2.0 on Wednesday morning. For those attending Storage Decisions in New York, stop by and say hello as I will also be in the expo hall during the ask the experts (ATE) sessions on Tuesday late afternoon. For those not attending, Storage Decisions usually posts a link to the slides shortly after the event as well as watch for several new pod casts, videos, tips and related content to appear soon, some of which will be produced next week while Im in New York City.

Also next week while in New York City, on Monday evening I will be the key-note speaker for the Storage Strategies for channel professionals event also at the New York Hilton.

Ok, nuff said.

Thank you Gartner for generating green awareness for my new book: The Green and Virtual Data Center!

Storage I/O trends

The other day Gartner issued a press release about their new findings that Users Are Becoming Increasingly Confused About the Issues and Solutions Surrounding Green IT.

This however what is missing from the Gartner report and action steps is to also say to read my new book “The Green and Virtual Data Center” (Auerbach).

However in all fairness, since Gartner has not yet seen it, I would seriously doubt that they would endorse anything other than one of their own publications.

Regardless, its great to see Gartner among others joining in and helping to transition industry awareness from Green Hype and help to close the Green gap (read more here and here) and begin addressing core issues that IT organizations can and are addressing to improve efficiency, address costs and enable sustainable business growth in an economic and environmental friendly way.

Thank you Gartner and let me know when and where you want a copy sent for a formal review and endorsement of my new book. Meanwhile, you can learn more at www.thegreenandvirtualdatacenter.com including a variety of green and related power, cooling, floor-space, environmental health and safety-EHS (PCFE) or green topics along with where to pre-order your advance copy from Amazon.com as well as other fine venues around the world.

Intelligent Power Management (IPM) and second generation MAID 2.0 on the rise

Storage I/O trends

In case you missed it today, Adaptec announced that they are the 1st vendor “This Week” to add support for Intelligent Power Management (IPM) to their storage systems. Adaptec joins a growing list of vendors who are deploying, or, who are program announcing some variation of IPM and second generation MAID 2.0 ability including support for different types of tiered disk drives including various combinations of Fibre Channel and SAS as well as SATA.

As a quick refresh, Massive or Monolithic Arrays of Idle or Inactive Disks (MAID) was popularized by 1st generation MAID vendor Copan who spins down disk drives to avoid energy usage. One of the challenges with 1st generation MAID is the poor performance by being able to only have at most 25% of the disk drives spinning at any time to transfer data when needed.

This is a balancing act between achieving energy avoidance and associated benefits vs. maintaining performance to move data when needed particularly for large restoration to support BC/DR or other purposes. Granted, 1st generation MAID systems like those from Copan while positioned as alternatives to high-performance disk storage systems to amplify potential energy savings on one hand, or, to put as an alternative to magnetic tape by providing random restore capability. The reality is that 1st generation MAID systems are finding their niche not for on-line primary or even on-line secondary storage, nor as a direct replacement for tape or even disk based libraries to support large-scale BC/DR, rather, in a sweet spot between secondary and near-line disk libraries and virtual tape libraries with a target application of very infrequently accessed of data.

Second generation MAID, aka MAID 2.0 is an evolution of the general technologies and capabilities extending functionality and flexibility while addressing quality of service (QoS), performance, availability, capacity and energy consumption using IPM also known as Adaptive Power Management (APM), dynamic bandwidth switching or scaling (DBS) among other names. The basic premise is to add flexibility building on 1st generation characteristics including data protection, resiliency and pro-active part or drive monitoring. Another basic premise of IPM. and MAID 2.0. solutions is to allow the performance and subsequent energy usage to vary, which is to cut the amount of performance and energy usage during in-active times, yet, when data needs to be accessed, to allow full performance without penalties for energy savings.

Second generation MAID solutions can be characterized by multiple power saving modes as well as flexible performance to adjust to changing workload and application needs. Another characteristic is the ability to work across different types of disk drives including Fibre Channel, SAS and SATA as opposed to only SATA drives found in 1st generation solutions as well as for the IPM or MAID 2.0 functionality to exist in a standard storage system or array instead of in a purpose-built dedicated storage system. Other capabilities include support for more granular power settings down to a RAID group or LUN level instead of across an entire array or storage system as well as support for different RAID levels among other features.

Examples of vendors who have either announced product or made statements of direction with regard to MAID 2.0 and IPM enabled storage systems include:

Adaptec (Today), Datadirect, EMC, Fujitsu, HDS, HGST (Hitachi Disk Drives), NEC, Nexsan, and Xyratex among others on a growing list of solutions.

For applications and data storage needs that need good performance and QoS over a range of changing usage conditions to balance good performance when needed to efficiently get work done to boost productivity, while saving or avoiding energy when little or no work needs to be done, take a look at current and emerging IPM and MAID 2.0 enabled storage systems as part of a tiered storage strategy to discuss power, cooling, floor-space and EHS (PCFE) related issues.

Closing the Green Gap – Green washing may be endangered, however addressing real green issues is here to stay

Storage I/O trends

Here’s a new article I wrote that just appeared over at Enterprise Storage Forum called Closing the Green Storage Gap.

Not all ‘green’ IT solutions or messages are created equal. Regardless of political views, the reality is that for business and IT sustainability, a focus on ecological issues and more importantly, their economic aspects cannot be ignored.

There are business benefits to using the most energy-efficient IT solutions to meet different data and application requirements. However, vendors are busy promoting ‘green’ stories and solutions that often miss where IT organization challenges and mandates exist. This article examines the growing gap between green messaging, or ‘Green Wash,’ and how to close the gap and enable IT organization issues to be addressed today in a way that sustains business growth in an economic and ecologically friendly way.

Have a read and a good weekend.

Ok, nuff said.
