Behind the Scenes, SANta Claus Global Cloud Story

There is a ton of discussion, stories, articles, videos, conferences and blogs about the benefits and value proposition of cloud computing. Not to mention, discussion or debates about what is or what is not a cloud or cloud product, service or architecture including some perspectives and polls from me.

Now SANta does not really care about these and other similar debates I have learned. However he is concerned with who has been naughty and nice as well watching out for impersonators or members of his crew who misbehave.

In the spirit of the holidays, how about a quick look at how SANta leverages cloud technologies to support his global operations.

Many in IT think that SANta bases his operations out of the North Pole as it is convenient for him to cool all of his servers, storage, networks and telecom equipment (which it is). However its also centrally located (See chart) for the northern hemisphere (folks down under may get serviced via SANtas secret Antarctica base of operations). Just like ANC (Anchorage International Airport) is a popular cargo transient, transload and refueling base for cargo carriers, SANta also leverages the north and South Pole regions to his advantage.

Now do not worry if you have never heard about SANta dual redundant South Pole operations, its one of his better kept secrets. Many organizations including SANtas partners such as Microsoft that have global mega IT operations and logistics centers have followed SANtas lead of leveraging various locations outside of the pacific northwest. Granted like some of his partners and managed service providers, he does maintain a presence in Washington Columbia river basin which provides a nice PR among other benefits.

Likewise, many in business as well as those in IT think that SANta leverages cloud technologies for cost savings or avoidance which is partially the case. However he also leverages cloud, hosting, managed service provider (MSP), virtual data centers, virtual operations centers, Xaas, SaaS or SOA technologies, services, protocols and products that are transparent and complimentary to his own in house resources addressing various business and service requirement needs.

What this has to do with the holidays and clouds is that you may not realize how Santa or St. Nick if you prefer (feel free to plug in whoever you like if Santa or St. Nick does not turn your crank) extensively relies on flexible and scalable resilient technologies for boosting productivity in a cost effective manner. Some of it is IT related, some of it is not. For example, from the GPS and Radar along with recently added RNP and RNAV enhanced capabilities to his increasingly high tech bio fueled powered sleigh, not to mention his information technology (IT) that powers his global operations, old St Nick has got it together when it comes to technology.

The heart or brains of the SANta operation is his global system operations center (SOC) or network operation center (NOC) that rivals those seen at NASA among others with multiple data feeds. The SOC is a 24×365 operations function that covers all aspects from transportation, logistics, distribution, assembly or packaging, financials back office, CRM, IT and communications among other functions.

Naturally, like the Apollo moon shots whose Grumman built LEM Lunar lander had to have 100% availability in that to get off of the moon, their engines only had to fire once, however it had to work 100% of the time! This thought process is said to have had leveraged principles from SANtas operations guide where he has one night a year to accomplish the impossible.

I should mention, while I cannot disclose (due to NDA) the exact locations of the SOCs, data or logistics centers, not to mention the vendors or the technology being used, I can tell you that they are all around you! The fully redundant SOCs, data and call centers as well as logistics sites (including staff, facilities, technology) leverage different time zones for efficiency.

SANtas staff have also found that the redundant SOCs, part of an approach across Santa entire vast organization has helped to guard against global epidemics and pandemics including SARs and H1N1 among others by isolating workers while providing appropriate coverage and availability, something many large organizations have since followed.

Carrying through on the philosophy of redundant SOCs, all other aspects of SANtas operations are distributed yet with centralized coordinated management, leveraging real-time situation awareness, event and activity correlation (what we used to call or refer to as AI), cross technology domain management, proactive monitoring and planning yet with ability for on the spot decision making.

What this means is that the various locations have ability to make localized decisions on the spot. However coordinated with primary operations or mission control to streamline global operations focus on strategic activity along with exceptions handling to be more effective. Thus it is not fully distributed nor fully centralized, rather a hybrid in terms of management, technologies and the way they work.

For example, to handle the diverse applications, there are some primary large processing and data retention facilities that backup, replicate information to other peer sites as well as smaller regional remote office branch offices close to where information services are needed. To say the environment is highly virtualized would be an understatement.

Likewise, optimization is key not just to keep costs low or avoid overheating some of SANtas facilities that are located in the Arctic and Antarctic regions that could melt the ice cap; they are also optimized to keep response time as low as possible while boosting productivity.

Thus, SANta has to rely on very robust and diverse communications networking leveraging LAN, SAN, MAN, WAN, POTS and PANs among other technologies. For example, his communications portfolio is said to involves landlines (copper and optical), RF including microwave and other radio based commutations supporting or using 3G, 4G, MPLS, SONET/SCH, xWDM, Microwave and Free space optics among others.

SANtas networking and communications elves are also said to be working with 5G and 100GbE multiplexed on 256 lambda WDM trunk circuits in non core trunk applications. Of course given the airborne operations, satellite and ACARS are a must to avoid over flying a destination while remaining in positive control during low visibility. Note that Santa routinely makes more CAT 3+ low visibility landings than most of the worlds airlines, air freight companies combined.

My sources also tell me that SANta has virtual desktop capability leveraging PCoIP and other optimizations on his primary and backup sleighs enabling rapid reconfiguration for changing workload conditions. He also is fully equipped with onboard social media capabilities for updates via twitter, Face book and Linked In among others designed by his chief social networking elf.

Consequently, given the vast amount of information needed to support his operations from CRM, shipping, tracking not to mention historical and profiling needs, transactional volumes both on the data as well as voice and social media networks dwarf the stock market trading volume.

Feeding SANtas vast organizations are online highly available robust databases for transactions purposes, reference unstructured data material including videos, websites and more. Some of which look hauntingly familiar given those that are part of SANtas eWorld Helpers initiative including: Sears, Amazon, NetFlix, Target, Albertsons, Staples, EMC, Wall mart, Overstock, RadioShack, Landsend, Dell, HP, eBay, Lowes, Publix, emusic, Riteaid and Supervalu among others (Im just sayin…).

The actual size of SANta information repository is a closely regarded secret as is the exact topology, schema and content structure. However it is understood that on peak days SANtas highly distributed high performance, low latency data warehouse sees upwards of 1,225PBytes of data added, one that is rumored to make Larry Ellison gush with excitement over its growth possibilities.

How does SANta pull this all off is by leveraging virtualization, automation, efficient and enabling technologies that allow him and elves (excuse me, associates or team members) to be more productivity in their areas of focus that is the envy of the universe.

Some of their efficiency is measured in terms of:

  • How many packages can be processed per elf with minimum or no mistakes
  • Number of calls, requests, inquiries per day per elf in a friendly and understandable manner
  • Knowing who has been naughty or nice in the blink of an eye including historical profiles
  • Virtual machines (VM) or physical machine (PM) servers managed per team member
  • Databases and applications, local and remote, logical and physical per team member
  • Storage in terms of PByte and Exabyte managed to given service level per team member
  • Network circuits and bandwidth with fewest dropped packets (or packages) per member
  • Fewest misdirected packages as well as aborted landings per crew
  • Fewest pounds gained from consumption of most milk and cookies per crew

From how many packages can be processed per hour, to the number of virtual servers per person, PBytes of data managed per person, network connections and circuits per person, databases and applications per person to takes and landings (SANta has the top of the list for this one), they are all highly efficient and effective.

Likewise, SANta leverages the partners in his SANtas eWORLD Helpers initiative network to help out where of course he looks for value; however value is not just lowest price per VM, lowest cost per TByte or cost per bandwidth. For SANta it is also very focused on performance, availability, capacity and economic efficiency not to mention quality with an environmentally friendly green supply chain.

By having a green supply chain, SANta leverages from a responsible, global approach that also makes economic sense on where to manufacture and produce or procure products. Contrary to growing popular belief, locally produced may not always be the most environmentally as well as economically favorable approach. For example (read more here), instead of growing flowers and plans in western Europe where they are consumed, a process that would require more energy for heat, lights, not to mention water and other resources. SANta has bucked the trend instead relying on the economics and environmental benefit of leveraging flowers and plants grown in warmer, sunnier climates.

Granted and rest assured, SANta still has an army of elves busily putting things together in his own factories along with managing IT related activities in a economically positive manner.

SANta has also leveraged this thinking to his data and information and communications networks leveraging sites such as in the arctic where solar power can be used during summer months along with cooling economizers to offset the impact of batteries, workload is shifted around the world as needed. This approach is rumored to be the envy of the US EPA Energy Star for Server, Storage and Data Center crew not to mention their followers.

How does SANta make sure all of the data and information is protected and available? Its a combination of best practices, techniques, technologies including hardware, software, data protection management tools, disk, dedupe, compression, tape and cloud among others.

Rest assured, if it is in the technology buzzword bingo book, it is a good bet that it has been tested in one of SANtas facilities, or, partner sites long before you hear about it even under a strict NDA discussion with one of his elves (opps, I mean supplier partners).

When asked of the importance of his information and data networks, resources and cloud enabled highly virtualized efficient operations SANta responded with a simple:

Ho Ho Ho, Merry Christmas to all, and to all, a good night!

As you sit back and relax, reflect, recreate, recoup or recharge, or whatever it is that you do this time of the year, take a moment to think about and thank all of SANtas helpers. They are the ones that work behind the scenes in SANtas facilities as well as his partners or suppliers, some in the clouds, some on or underground to make the worlds largest single event day (excuse me, night) possible! Or, is this SANta and cloud thing all just one big fantasy?

Happy and safe holidays or whatever you want to refer to it as, best wishes and thanks!

BTW: FTC disclosure information can be found here!

Is MAID Storage Dead? I Dont Think So!

Some vendors are doing better than others and first generation MAID (Massive or monolithic Array of Idle Disks) might be dead or about to be deceased, spun down or put into a long term sleep mode, it is safe to say that second generation MAID (e.g. MAID 2.0) also known as intelligent power management (IPM) is alive and doing well.

In fact, IPM is not unique to disk storage or disk drives as it is also a technique found in current generation of processors such as those from Intel (e.g. Nehalem) and others.

Other names for IPM include adaptive voltage scaling (AVS), adaptive voltage scaling optimized (AVSO) and adaptive power management (APM) among others.

The basic concept is to vary the amount of power being used to the amount of work and service level needed at a point in time and on a granular basis.

For example, first generation MAID or drive spin down as deployed by vendors such as Copan, which is rumored to be in the process of being spun down as a company (see blog post by a former Copan employee) were binary. That is, a disk drive was either on or off, and, that the granularity was the entire storage system. In the case of Copan, the granularly was that a maximum of 25% of the disks could ever be spun up at any point in time. As a point of reference, when I ask IT customers why they dont use MAID or IPM enabled technology they commonly site concerns about performance, or more importantly, the perception of bad performance.

CPU chips have been taking the lead with the ability to vary the voltage and clock speed, enabling or disabling electronic circuitry to align with amount of work needing to be done at a point in time. This more granular approach allows the CPU to run at faster rates when needed, slower rates when possible to conserve energy (here, here and here).

A common example is a laptop with technology such as speed step, or battery stretch saving modes. Disk drives have been following this approach by being able to vary their power usage by adjusting to different spin speeds along with enabling or disabling electronic circuitry.

On a granular basis, second generation MAID with IPM enabled technology can be done on a LUN or volume group basis across different RAID levels and types of disk drives depending on specific vendor implementation. Some examples of vendors implementing various forms of IPM for second generation MAID to name a few include Adaptec, EMC, Fujitsu Eternus, HDS (AMS), HGST (disk drives), Nexsan and Xyratex among many others.

Something else that is taking place in the industry seems to be vendors shying away from using the term MAID as there is some stigma associated with performance issues of some first generation products.

This is not all that different than what took place about 15 years ago or so when the first purpose built monolithic RAID arrays appeared on the market. Products such as the SF2 aka South San Francisco Forklift company product called Failsafe (here and here) which was bought by MTI with patents later sold to EMC.

Failsafe, or what many at DEC referred to as Fail Some was a large refrigerator sized device with 5.25” disk drives configured as RAID5 with dedicated hot spare disk drives. Thus its performance was ok for the time doing random reads, however writes in the pre write back cache RAID5 days was less than spectacular.

Failsafe and other early RAID (and here) implementations received a black eye from some due to performance, availability and other issues until best practices and additional enhancements such as multiple RAID levels appeared along with cache in follow on products.

What that trip down memory (or nightmare) lane has to do with MAID and particularly first generation products that did their part to help establish new technology is that they also gave way to second, third, fourth, fifth, sixth and beyond generations of RAID products.

The same can be expected as we are seeing with more vendors jumping in on the second generation of MAID also known as drive spin down with more in the wings.

Consequently, dont judge MAID based solely on the first generation products which could be thought of as advanced technology production proof of concept solutions that will have paved the way for follow up future solutions.

Just like RAID has become so ubiquitous it has been declared dead making it another zombie technology (dead however still being developed, produced, bought and put to use), follow on IPM enabled generations of technology will be more transparent. That is, similar to finding multiple RAID levels in most storage, look for IPM features including variable drive speeds, power setting and performance options on a go forward basis. These newer solutions may not carry the MAID name, however the sprit and function of intelligent power management without performance compromise does live on.

Ok, nuff said.

SSD and Storage System Performance

Jacob Gsoedl has a new article over at SearchStorage titled How to add solidstate storage to your enterprise data storage systems.

In his article which includes some commentary by me, Jacob lays out various options on where and how to deploy solid state devices (SSD) in and with enterprise storage systems.

While many vendors have jumped on the latest SSD bandwagon adding flash based devices to storage systems, where and how they implement the technologies varies.

Some vendors take a simplistic approach of qualify flash SSD devices for attachment to their storage controllers similar to how any other Fibre Channel, SAS or SATA hard disk drive (HDD) would be.

Yet others take a more in depth approach including optimizing controller software, firmware or micro code to leverage flash SSD devices along with addressing wear leveling, read and write performance among other capabilities.

Performance is another area where on paper a flash SSD device might appear to be fast and enable a storage system to be faster.

However, systems that are not optimized for higher throughput and or increased IOPs needing lower latency may end up placing restrictions on the number of flash SSD devices or other configuration constraints. Even worse is when expected performance improvements are not realized as after all, fast controllers need fast devices, and fast devices need fast controllers.

RAM and flash based SSD are great enabling technologies for boosting performance, productivity and enabling a green efficient environment however do your homework.

Look at how various vendors implement and support SSD particularly flash based products with enhancements to storage controllers for optimal performance.

Likewise check out the activity of  the SNIA Solid State Storage Initiative (SSSI) among other industry trade group or vendor initiatives around enhancing along with best practices for SSD.

The other Green Storage: Efficiency and Optimization

Some believe that green storage is specifically designed to reduce power and cooling costs.

The reality is that there are many ways to reduce environmental impact while enhancing the economics of data storage besides simply booting utilizing.

These include optimizing data storage capacity as well as boosting performance to increase productivity per watt of energy used when work needs to be done.

Some approaches require new hardware or software while others can be accomplished with changes to management including reconfiguration leveraging insight and awareness of resource needs.

Here are some related links:

PUE, Are you Managing Power, Energy or Productivity?

With a renewed focus on Green IT including energy Efficiency and Optimization of servers, storage, networks and facilities, is your focus on managing power, energy, or, productivity?

For example, do you use or are interested in metrics such as Greengrid PUE or 80 Plus efficient power supplies along with initiatives such as EPA Energy Star for servers and emerging Energy Star for Data Center for Storage in terms of energy usage?

Or are you interested in productivity such as amount of work or activity that can be done in a given amount of time,or how much information can be stored in a given footprint (power, cooling, floor space, budget, management)?

For many organizations, there tends to be a focus and in both managing power along with managing productivity. The two are or should interrelated, however there are some disconnects with some emphasis and metrics. For example, the Green grid PUE is a macro facilities centric metric that does not show the productivity, quality or measure of services being delivered by a data center or information factory. Instead, PUE provides a gauge of how the habitat, that is the building and power distribution along with cooling are efficient with respect to the total energy consumption of IT equipment.

As a refresher, PUE is a macro metric that is essentially a ratio of how much total power or energy goes into a facility vs. the amount of energy used by IT equipment. For example, if 12Kw (smaller room/site) or 12Mw (larger site) are required to power an IT data center or computer room for that matter, and of that energy load, 6kWh or 6Mw, the PUE would be 2. A PUE of 2 is an indicator that 50% of energy going to power a facility or computer room goes towards IT equipment (servers, storage, networks, telecom and related equipment) with the balance going towards running the facility or environment which typically has had the highest percentage being HVAC/cooling.

In the case of EPA Energy Star for Data Centers which initially is focused on the habitat or facility efficiency, the answer is measuring and managing energy use and facility efficiency as opposed to productivity or useful work. The metric for EPA Energy Star for Data Center initially will be Energy Usage Effectiveness (EUE) that will be used to calculate a ratting for a data center facility. Those data centers in the top25 percentile will qualify for Energy Star certification.

Note the word energy and not power which means that the data center macro metric based on Green grid PUE rating looks at all source of energy used by a data center and not just electrical power. What this means is that a macro and holistic facilities energy consumption could be a combination of electrical power, diesel, propane or natural gas or other fuel sources to generate or create power for IT equipment, HVAC/Cooling and other needs. By using a metric that factor in all energy sources, a facility that uses solar, radiant, heat pumps, economizers or other techniques to reduce demands on energy will make a better rating.

By using a macro metric such as EUE or PUE (ratio = Total_Power_Used / IT_Power_Needs), a starting point is available to decide and compare efficiency and cost to power or energize a facility or room also known as a habitat for technology.

Managing Productivity of Information Factories (E.g. Data Centers)
What EUE and PUE do not reflect or indicate is how much data is processed, moved and stored by servers, storage and networks within a facility. On the other hand or extreme from macro metrics are micro or component metrics that gauge energy usage on an individual device basis. Some of these micro metrics may have activity or productivity indicator measurements associated with them, some don’t. Where these leave a big gap and opportunity is to fill the span between the macro and micro.

This is where work is being done by various industry groups including SNIA GSI, SPC and SPEC among others along with EPA Energy Star among others to move beyond macro PUE indicators to more granular effectiveness and efficiency metrics that reflect productivity. Ultimately productivity is important to gauge,  the return on investment and business value of how much data can be processed by servers, moved via networks or stored on storage devices in a given energy footprint or cost.

In Figure 1 are shown four basic approaches (in addition to doing nothing) to energy efficiency. One approach is to avoid energy usage, similar to following a rationing model, but this approach will affect the amount of work that can be accomplished. Another approach is to do more work using the same amount of energy, boosting energy efficiency, or do same amount of work (or storage data) however with less energy.

Tiered Storage
Figure 1 the Many Faces of Energy Efficiency Source: The Green and Virtual Data Center(CRC)

The energy efficiency gap is the difference between the amount of work accomplished or information stored in a given footprint and the energy consumed. In other words, the bigger the energy efficiency gap, the better, as seen in the fourth scenario, doing more work or storing more information in a smaller footprint using less energy. Clock here to read more about Shifting from energy avoidance to energy efficiency.

Watch for new metrics looking at productivity and activity for servers, storage and networks ranging from MHz or GHz per watt, transactions or IOPS per watt, bandwidth, frames or packets processed per watt or capacity stored per watt in a given footprint. One of the confusing metrics is Gbytes or Tbytes per watt in that it can mean storage capacity or bandwidth, thus, understand the context of the metric. Likewise watch for metrics that reflect energy usage for active along with in-active including idle or dormant storage common with archives, backup or fixed content data.

What this all means is that work continues on developing usable and relevant metrics and measurement not only for macro energy usage, also, to gauge the effectiveness of delivering IT services. The business value proposition of driving efficiency and optimization including increased productivity along with storing more information in a given footprint is to support density and business sustainability.

Clouds are like Electricity: Dont be Scared

Clouds

IT clouds (compute, applications, storage, and services) are like electricity in that they can be scary or confusing to some while being enabling or a necessity s to others not to mention being a polarizing force depending on where you sit or view them.

As a polarizing force, if you are a cloud crowd cheerleader or evangelist, you might view someone who does not subscribe or share your excitement, views or interpretations as a cynic.

On the other hand, if you are a skeptic, or perhaps scared or even a cynic, you might view anyone who talks about cloud in general or not specific terms as a cheerleader.

I have seen and experienced this electrifying polarization first hand having being told by crowd cloud cheerleaders or evangelists that I dont like clouds, that Im a cynic who does not know anything about clouds.

As a funny aside (at least I thought it was funny), I recently asked someone who gave me an ear full while they were trying to convert me to be a cloud believer if they had read any of the chapters in my new book The Green and Virtual Data Center (CRC). The response was NO and I said to the effect to bad, as in the book, I talk about how clouds can be complimentary to existing IT resources as being another tier of servers, storage, applications, facilities and IT services.

On the other hand, and this might be funny for some of the crowd cloud, when I bring up tiered IT resources including servers, storage, applications and facilities as well as where or how clouds can fit to compliment IT, I have been told by cynics or naysayers that Im a cloud cheerleader.

Wow, talk about polarized sides!

Now, what about all those that are somewhere in the middle, those that are skeptics who might see value for IT clouds for different scenarios and may in fact already be using clouds (depending upon someones definition).

For those in the middle, whether they are vendors, vars, media, press, analysts, consultants, IT professionals, investors or others, they can easily be misunderstood, misrepresented, and a missed opportunity, perhaps even lamented by those on either of the two extremes (e.g. cloud crowd cheerleaders or true skeptic nay sayers).

Time for some education, don’t be scared, however be careful!

When I worked for an electric power generating and transmission utility an important lesson was not to be scared of electricity, however, be educated, what to do, what not to do in different situations including what to do or not do in the actual power plant or substation. I was taught that when in the actual plant, or at a substation of which I visited in support of the applications and systems I was developing or maintaining, to do certain things. For example, number one, dont touch certain things, number two, if you fall, don’t grab anything, the fall may or may not hurt you, let alone the sudden stop where ever you land, however, if you grab something, that might kill you and you may not be able to let go further injuring yourself. This was a challenging thought as we are taught to grab onto something when falling.

What does this have to do with clouds?

Don’t grab and hang-on if you don’t know what you are grabbing on to if you don’t have to.

The cloud crowd can be polarizing and in some ways acting as a lightning rod drawing the scorns, cynicism ,skeptics, lambasting or being poked fun of given some of the over the top hype around clouds today. Now granted, not all cloud evangelists, vendors or cheerleaders deserve to be the brunt of some of this backlash within the industry; however, it comes with the territory.

Im in the middle as I pointed out above when I talk with vendors, vars, media, investors and IT customers.  Some I talk with are using clouds (perhaps not compliant with some of the definitions). Some are looking at clouds to move problems or mask issues, others are curious yet skeptical to see where or how they could use clouds to compliment their environments. Yet others are scared however maybe in the future will be more open minded as they become educated and see technologies evolve or shift beyond a fashionable trend.

So its time for disclosure, I seeIT clouds as being complimentary that can co-exist with other IT resources (servers, storage, software). In essence, my view is that clouds are just another tier of IT resources to be used when and where applicable as opposed to being a complete replacement, or, simply ignored.

My point is that cloud computing is another tier of traditional computing or servers providing a different performance, availability, capacity, economic and management attributes compared to other traditional technology delivery vehicles. Same thing with storage, same thing with data centers or hosting sites in general. This also applies to application services, in that a cloud web, email, expense, sales, crm, erp, office or other applications is a tier of those same implementations that may exist in a traditional environment. After all, legacy, physical, virtual, grid and cloud IT datacenters all have something in common, they rely on physical servers, storage, networks, software, metrics and management involving people, processes and best practices.

Now back to disclosure, I like clouds, however Im not a cloud cheerleader, Im a skeptic at times of some over the top hype, yet I also personally use some cloud services and technologies as well as advise others to leverage cloud services when, or where applicable to compliment, co-exist and help enable a green and virtual data center and information factory.

To the cloud crowd cheerleaders, too bad if I don’t line up with all of your belief systems or if you perceive me as raining on your parade by being a skeptic , or what you might think of as a cynic and non believer, even though I use clouds myself.

Likewise, to the true cynics (not skeptics) or naysayers, ease up, Im not drinking the cool-aid of the cheerleaders and evangelists, or at least not in large excessive binge doses. I agree that clouds are not the solution to every IT issue, regardless of what your definition of a cloud happens to be.

To everyone else, regardless of if you are the minatory or majority out there that do not fall into one of the two above groups I have this to say.

Dont be afraid, dont be scared of clouds, learn to navigate your way around and through the various technologies, techniques, products and services and indemnity where they might compliment and enable a flexible and scalable resilient IT infrastructure.

Take some time to listen and learn, become educated on what the different types of clouds (public, private, services, products, architectures, or marketecture), their attributes (compute, storage, applications, services, cost, availability, performance, protocols, functionality) and value proposition.

Look into how cloud technologies and techniques might compliment your existing environment to meet specific business objectives. You might find there are fits, you might there are not, however have a look and do some research so that you can at least hold your ground if storm clouds roll in.

After all, clouds are just another tier of IT resources to add to your tool box enabling more efficient and effective IT services delivery. Clouds do not have to be the all or nothing value proposition that often end up in discussions due to polarized extreme views and definitions or past experiences.

Look at it this way, IT relies on electricity, however electricity needs to be understood and respected not to mention used in effective ways. You can be scared of electricity, you can be caviler around it, or, it can be part of your environment and enabler as long as you know when, where and how to use it, not to mention not using it as applicable.

So next time you see a cloud crowd cheerleader, give them a hug, give them a pat on the back, an atta boy or atta girl as they are just doing their jobs, perhaps even following their beliefs and in the line of duty taking a lot of heat from the industry in the pursuit of their work.

On the other hand, as to the cynics and naysayers, they may in fact be using clouds already, perhaps not under the strict definition of some of the chieftains of the cloud crowd.

To everyone else, dont worry, don’t by scared about the clouds, instead, focus on your business, you IT issues and look at various tiers of technologies that can serve as an enabler in a cost effective manner.

Ok, nuff said.

Catch of the day or post of the day!

Ok, I know, its been a couple of weeks since my last post. Sure I have been tweeting now and then, attending several briefings with new emerging as well as existing vendors for up-coming announcements, not to mention getting some other content out from webcasts, to podcasts, or videos, interviews, articles, tips and presentations at various events, pertaining to Green IT, virtualization, cloud storage and computing, backup, data protection, performance, capacity planning among other topics.

Anyway, for now a quick post as I have many others that I have been wanting to do and will be doing soon, however wanted to get a few things out sooner vs. later, and after all, all work and no play makes for a dull day right?

Well, last week after spending a couple of days in Chicago at Storage Decisions where I presented a couple of sessions and recorded several videos, I had a chance to get out and do some fishing and catching. Fishing is always great, however catching (and release) is even more fun, especially when you can catch some, toss some, and keep some for dinner which is what occurred last week when my friend Rob and me ventured out for a couple of hours and found where the fish were (see picture) on the St. Croix river.

Catch of the Day

Rob on left (Bruins warm up jacket for Bass fishing), Greg on the right (Mustang PFD Jacket)

Catch of the day line-up
From right to left, bottle bass (caught at the dock ;) ), stripped bass, northern pike (swamp shark), more stripped bass, and another bottle bass (also caught at the dock).

Ok, nuff fish talk for now, back to work, get a few things done, and then maybe this weekend, get another blog post done, maybe some fishing, and enjoying the summer weather before heading off to Toronto on Monday for Storage Decisions on Tuesday, then a couple of webcasts and web radio events on Wednesday among other activities.

March and Mileage Mania Wrap-up

Today’s flight to Santa Ana (SNA) Orange County California for an 18 hour visit marks my 3rd trip to the left coast in the past four weeks that started out with a trip to Los Angeles. The purpose of today’s trip is to deliver a talk around Business Continuance (BC) and Disaster recovery (DR) topics for virtual server and storage environments along with related data transformation topics themes, part of a series of on-going events.

Planned flight path from MSP to SNA, note upper midwest snow storms. Thanks to Northwest Airlines, now part of Delta!
Planned flight path from MSP to SNA courtesy of Northwest Airlines, now part of Delta

This is a short trip to southern California in that I have to be back in Minneapolis for a Wednesday afternoon meeting followed by keynoting at an IT Infrastructure Optimization Seminar downtown Minneapolis Thursday morning. Right after Thursday morning session, its off to the other coast for some Friday morning and early afternoon sessions in the Boston area, the results of which I hope to be able to share with you in a not so distant future posting.

Where has March gone? Its been a busy and fun month out on the road with in-person seminars, vendor and user group events in Minneapolis, Los Angles, Las Vegas, Milwaukee, Atlanta, St. Louis, Birmingham, Minneapolis for CMG user group, Cincinnati and Orange County not to mention some other meetings and consulting engagements elsewhere including participating in a couple of webcast and virtual conference/seminars while on the road. Coverage and discussion around my new book "The Green and Virtual Data Center" (CRC) continues expand, read here to see what’s being said.

What has made the month fun in addition to traveling around the country is the interaction with the hundreds of IT professionals from organizations of all size hearing what they are encountering, what their challenges are, what they are thinking, and in general what’s on their mind.

Some of the common themes include:

  • There’s no such thing as a data recession, however the result is doing more with less, or, with what you have
  • Confusion abounds around green hype including carbon footprints vs. core IT and business issues
  • There is life beyond consolidation for server and storage virtualization to enable business agility
  • Security and encryption remain popular topic as does heterogeneous and affordable key management
  • End to end IT resource management for virtual environments is needed that is scalable and affordable
  • Performance and quality of service can not be sacrificed in the quest to drive up storage utilization
  • Clouds, SSD (FLASH), Dedupe, FCoE and Thin Provisioning among others are on the watch list
  • Tape continues to be used complimenting disks in tiered storage environments along with VTLs
  • Dedupe continues to be deployed and we are just seeing the very tip of the ice-berg of opportunity
  • Software licensing cost savings or reallocation should be a next step focus for virtual environments

    • Now, for a bit of irony and humor, overheard was a server sales person talking to a storage sales person comparing notes on how they are missing their forecasts as their customers are buying fewer servers and storage now that they are consolidating with virtualization, or using disk dedupe to eliminate disk drives. Doh!!!

    Now if those sales people can get their marketing folks to get them the play book for virtualization for business agility, improving performance and enabling business growth in an optimized, transformed environment, they might be able to talk a different story with their customers for new opportunities…

    What’s on deck for April? More of the same, however also watch and listen for some additional web based content including interviews quotes and perspectives on industry happenings, articles, tips and columns, reports, blogs, videos, podcasts, webcasts and twitter activity as well as appearances at events in Boston, Chicago, New Jersey and Providence among other venues.

    To all of those who came out to the various events in March, thank you very much and look forward to future follow-up conversations as well as seeing you at some of the upcoming future events.

    Cheers gs

    Remember The Alamo

    Yesterday I made a quick trip down to San Antonio Texas (SAT) to do a keynote talk about "BC/DR and Virtual Environments" along with a sprinkling of IT effieincy aka Green; consolidation, power, cooling, footprint, data management and cloud topics mixed in the discussion. The dinner event was put on by TechTarget with the local host being Mobius (not to be confused with Moby, the artist). Mobius is a Texas value added reseller (VAR) and the event took place at Morton’s near the river walk in downtown SAT. This was my second trip to SAT in about two months have done a morning seminar talk about the "Wide World of Archiving – Life beyond Compliance" back in October, also downtown SAT.

    It was a great event with a lively and interesting audience who provide good feedback and conversation sharing their experiences, concerns, issues and what they are looking at or for.

    Some general take away’s that I have from talking with the IT folks who were in attendance at the event include:

  • Do you homework and due diligence with regard to using VCBs for VMware backups
  • Pay attenion to the details when re-architecting and updating data protection for virtual environments
  • iSCSI and FC as well as FCoE all have different roles and places now and into the future for virtual environments
  • Concern about clouds, they are interesting, are a tiered resource to compliment other resources
  • Cloud services need to be part of BC/DR including in plans to isolate against disruptions such what occurred with Amazon and others
  • Not all servers can be consolidated due to different reasons and issues
  • Virtualization platforms (software and appliance or storage system based) can be used for replication, migration and consolidation
  • Virtual tape libraries are being adopted while tape usage continues
  • Discussion around different tiers of storage, tiered access (e.g. iSCSI, FC, FCoE, IBA, NAS, etc) and tiered data protection
  • A common theme is doing more with less, maintaining service levels and support business growth

    • Now on a different note, from technology and trends to travel.

    If you travel enough for business like I have had, you know that its not all jet set lifestyle like people think or assume, in fact many times what I get to see of a city or venue is the view from window of a car or train on the way from an airport to a venue, a hotel and sometimes a dinner event. However now and then, even on quick trips like yesterdays where I was in SAT for 15 hours, opportunities exist to get out even if its for just a moment and take in a site or two, see some of the city or area. Last night was an example of getting a chance to see something interesting when I walked the 7-8 blocks from the venue (I had gone directly from the airport to Mortons).

    Walking back to my hotel (it was a nice evening for a walk) last night, I walked around and near the river walk and low and behold, I stopped, turned and looked and there it was, the Alamo (see photo below taken from my cell phone) in all its splendor. It actually looks a lot smaller than what I thought it would look like, however it was fun to do some inadvertent site seeing before an early morning flight home.

    The Alamo
    Remember the Alamo via Greg’s Cell Phone Camera 12/10/08

    Now lets put travel into perspective here a bit.

    When I woke up yesterday morning it was 3F at home in Stillwater, by time I got to the airport it was a balmy 9F, by mid afternoon when I arrived in SAT and stood in the taxi line, it was a down right tropical in the mid 50s F. This morning when I woke up around 5:30AM for my early morning flight home, it was a cool 35F in SAT with a forecast of getting back up into the 50s (F) today while it was a pleasant 13F when I arrived back at my office early afternoon, the fun of traveling!

    Thanks to everyone who came out to last nights event and it was great to have had a chance to meet and visit with you, hopefully next time we will have more time for follow-up questions, however feel free to drop me a note. Also thanks too the Techtarget, Mobius and Mortons folks for putting a great event together, and, remember the Alamo and if you have not been there, check it and the river walk out!

    Cheers gs

    Downloads for fall 2008 San Francisco Storage Decisions now available

    The TechTarget Storage Media Group has posted on Bitpipe the session presentations from the recent fall (November 17-19th) 2008 San Francisco Storage Decisions event. If you have never been to a Storage Decisions event, it?s a great venue for meeting with IT and storage professionals as well as vendors who also show up to show their wares and meet with the attendees. Make no mistake about it, Storage Decisions is not a vendor to vendor meet and industry network event like SNW or a vendor sponsored user group like VMworld or EMCworld, rather, its focused on the IT and storage professional and encourages speakers to be frank and candid in their discussions of technologies, techniques and even of vendors and their solutions.

    In addition to doing a keynote session Wednesday evening November 19th on ?Hot Storage Topics for Channel Professionals? at the Storage Strategies for Channel Professionals Dinner event, I also did two presentations at Storage Decisions one in the management and executive track Management and Executive Track on Green and Efficient Storage , an (updated version from what was covered in September 2008 at New York) timely theme given my new book ?The Green and Virtual Data Center? (Auerbach) along with another session in the Storage and capacity management track of  ?Clustered and Grid Storage — From SMB, to Scientific, to Social Networking and Web 2.0? (also updated from September 2008)

    View the entire list of all Storage Decisions sessions here.

    A big thanks to all who came out last week in San Francisco at Storage Decisions and who attended the sessions enabling great discussion and insight both during the sessions, as well as during lunches, breaks and exhibition hours.

    Cheers gs

    Storage Optimization: Performance, Availability, Capacity, Effectiveness

    Storage I/O trends

    With the IT and storage industry shying away from green hype, green washing and other green noise, there is also a growing realization that the new green is about effectively boosting efficiency to improve productivity and profitability or to sustain business and IT growth during tough economic times.

    This past week while doing some presentations (I’ll post a link soon to the downloads) at the 2008 San Francisco installment of Storage Decisions event focused on storage professionals, as well as a keynote talk at the value added reseller (VAR) channel professional focused storage strategies event, a common theme was boosting productivity, improving on efficiency, stretching budgets and enabling existing personal and resources to do more with the same or less.

    During these and other presentations, keynotes, sessions and seminars both here in the U.S. as well as in Europe recently, these common themes of booting efficiency as well as the closing of the green gap, that is, the gap between industry and marketing rhetoric around green hype, green noise, green washing and issues that either do not resonate with, or, can not be funded by IT organizations compared with the disconnect of where many IT organizations issues exist which are around power, cooling, floor space or footprint as well as EH&S (Environmental health and safety) and economics.

    The green gap (here, and here, and here) is that many IT organizations around the world have not realized due to green hype around carbon footprints and related themes that in fact, boosting energy efficiency for active and on-line applications, data and workloads (e.g. doing more I/O operations per second-IOPS, transactions, files or messages processed per watt of energy) to address power, cooling, floor space are in fact a form of addressing green issues, both economic and environmental.

    Likewise for inactive or idle data, there is a bit more of a linkage that green can mean powering things off, however there is also a disconnect in that many perceive that green storage for example is only green if the storage can be powered off which while true for in-active or idle data and applications, is not true for all data and applications types.

    As mentioned already, for active workloads, green means doing more with the same or less power, cooling and floor space impact, this means doing more work per unit of energy. In that theme, for active workload, a slow, large capacity disk may in fact not be energy efficient if it impedes productivity and results in more energy to get the same amount of work done. For example, larger capacity SATA disk drives are also positioned as being the most green or energy efficiency which can be true for idle or in-active or non performance (time) sensitive applications where more data is stored in a denser footprint.

    However for active workload, lower capacity 15.5K RPM 300GB and 400GB Fibre Channel (FC) and SAS disk drives that deliver more IOPS or bandwidth per watt of energy can get more work done in the same amount of time.

    There is also a perception that FC and SAS disk drives use more power than SATA disk drives which in some cases can be true, however current generations of high performance 10K RPM and 15.5K RPM drives have very similar power draw on a raw spindle or device basis. What differs is the amount of capacity per watt for idle or inactive applications, or, the number of IOPS or amount of performance for active configurations.

    On the other hand, while not normally perceived as being green compared to tape or IPM and MAID (1st generation and MAID 2.0) solutions, along with SSD (Flash and RAM), not to mention fast SAS and FC disks or tiered storage systems that can do more IOPS or bandwidth per watt of energy are in fact green and energy efficiency for getting work done. Thus, there are two sides to optimizing storage for energy efficiency, optimizing for when doing work e.g. more miles per gallon per amount of work done, and, how little energy used when not doing work.

    Thus, a new form of being green to sustain business growth while boosting productivity is Gaining Realistic Economic Efficiency Now that as a by product helps both business bottom lines as well as the environment by doing more with less. These are themes that are addressed in my new book

    “The Green and Virtual Data Center” (Auerbach) that will be formerly launched and released for generally availability just after the 1st of the year (hopefully sooner), however you can beat the rush and order your copy now to beat the rush at Amazon and other fine venues around the world.

    Ok, nuff said.

    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.

    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.

    Ok, nuff said.
