I returned safely from my trip to Tulsa, Oklahoma.
(A special shout-out to Shannon at [In The Raw] sushi restaurant, and my new friends I met at the rooftop of [the Mayo]!)
Last week I was in Auckland, New Zealand teaching Top Gun class. Top Gun teaches IBM Business Partners and sales reps how to sell our products, services, and solutions. I have been teaching Top Gun classes around the world since 1998.
(Why didn't I post sooner? Because IBM's developerWorks was getting an exciting upgrade to IBM Connections 4.0, and bloggers like me have to wait for the conversion to complete!)
While many of my trips in the USA involve traveling alone, that is not the case for Top Gun classes. Our class manager, Joe Ebidia, brought his wife Karen. Our class administrator is Hyein (Hyein is a Korean name that rhymes with rain). In addition to some local instructors, I am joined by my IBM USA colleagues Scott McPeek (Tivoli Storage) and Vic Peltz (Disk/Replication/Competitive Sales).
The rest of the teach team arrived a day or two early to adjust to jet lag. I, on the other hand, got off the plane Monday at 6am, and had a business meeting that same morning with GTS architects from Wellington.
Clockwise from left: Karen is vegetarian, and had some pasta with tomato sauce. Hyein had a lamb burger. Joe had flounder. I had salmon risotto. Yum!
(To those asking why I have only the bellies of Karen and Joe in the picture, I was focused on taking picture of the food.)
After setting up the classroom, we took a ferry over to [Devonport], a charming seaside village just minutes across the bay from Auckland. The ferry boats were close the the Central Business District our [Stamford Plaza hotel] was in, and they run every 30 minutes.
The four of us walked up to the top of Mt. Victoria to see the views of the city. I highly recommend this! Once you get to Devonport, you can walk along the streets to see all the cute shops, or enjoy the parks and natural beauty. I had [done this before], but it is always worth doing again!
The class is four days long. I had six presentations. Here were the first three:
Selling IBM Storwize V7000 and V7000 Unified. Scott McPeek had already covered SAN Volume Controller (SVC), so it was easy to explain the Storwize V7000. For the V7000 Unified, I went into more detail of the file-based protocols and features, paving the way for Vic's "Selling SONAS" later in the week.
Selling IBM Storwize V3700. Having covered the SVC and Storwize V7000, my presentation on the Storwize V3700 focuses more on the positioning of when to sell which product for particular workloads.
Understanding IBM's Big Four Initiatives. This was an interesting request. I was asked to cover Social, Mobile, Analytics and Cloud (what we internally call SMAC) from a storage perspective. Social included Social Media, Social Networking and Social Business. Mobile focused on IBM's Mobile First campaign. Analytics included big data, Hadoop, and our various solutions for performing analytics. Cloud included IBM's Cloud Computing Reference Architecture (CCRA), IBM SmartCloud Enterprise storage, our Backup and Archive clouds, and the new SmartCloud Storage portfolio.
I will save the rest of the week for the next post!

I am back from my awesome vacation in and around Portland, Oregon! I rented a hybrid Toyota Prius from Hertz, which got about 50 MPG for this trip.
After flying all day on Monday, I spent Tuesday driving to the Pacific Ocean, visiting Astoria, made famous by movies like ["The Goonies"] and ["Kindergarten Cop"].
Then on to [Fort Clatsop] and [Fort Stevens Park]. This is the end-point of the famous [Lewis and Clark expedition] trail.
In Seaside, I was able to walk the beach, get some [salt-water taffy], and have a snack at the local [Pig 'N Pancake].
On Wednesday, I walked through the gardens of [The Grotto] on Sandy Blvd, ate a German lunch at [The Rheinelander], then visited the [Crown Point Vista House] along the [Columbia River Gorge]. There were several fabulous waterfalls that could be seen from the parking area without hiking into the wilderness. We wouldn't want to encounter a bear in the woods, or a cow in the field!
Afterwards, I drove to the [Timberline lodge] at the peak of Mt. Hood to watch the snow fall and have dinner and drinks. This is the lodge featured in the movie ["The Shining"].
Thursday was a Spa day, which I spent relaxing at the pool and sauna. In the evening, I had dinner at [Henry's Tavern], and then shopped at [Powell's Books].
Friday morning I spent at the Oregon Museum of Science and Industry [OMSI], which had an [explosive exhibition based on the television show "Mythbusters"]. I then saw the OMNIMAX film ["Sea Monsters"] which followed the life of a pre-historic sea animal called Dolly.
In the afternoon, Rafael, Mo and I explored Portland's waterfront and various bridges via [Segway tour]. The cherry blossoms along our path were in full bloom. If you have not ridden on one of these Segway scooters, they are a lot of fun!
I had dinner at [Bridgeport Brewery] then took a short walk over to see [ComedySportz], a comedy improv show.
On Saturday, Portland held their [Saturday Market] with arts and crafts for sale. This is similar to Tucson's 4th Avenue Street fair. The difference is that the "Saturday Market" occurs every Saturday of the year and Tucson's 4th Avenue Street Fair occurs only twice per year. The weather was very nice, so, many of the locals were in t-shirts and shorts. A live concert by [Grupo Condor] were playing on the main stage.
I walked past the [Voodoo Donuts store]. There was a long line to get in. A woman leaving the store carrying a pink donut box complained she waited 2 hours just to spend $28 for a dozen donuts. The magic is in the hole!
Getting out of the hustle and bustle of the Saturday Market, I had some green tea at the [Lan Su Chinese Garden]. A sister city to Portland is Suzhou, China, and this garden was very peaceful to walk through.
I went back to Powell's Books, did some shopping for shoes at [Dr. Martens], and had some pizza and salad at [Sizzle Pie] next door.
Nearly everything was closed on Easter Sunday, so I went down to the [TulipFest at the Wooden Shoe Tulip Farm] in Woodburn, OR. This was the opening weekend, with over 40 acres of flowers to walk through, various food carts, wine tasting, and rides for the kids.
My final dinner in Portland was at the [Red Star Tavern and Roadhouse], just a few blocks from my hotel.
Getting back to Tucson proved to be a bit challenging. The flight from Portland to San Francisco was delayed due to fog, so we got re-routed to Seattle, then back to Los Angeles, and finally to Tucson.
Well, it is Halloween
back in the USA. I am in Seoul Korea this week, so it is already Thursday, November 1st here, but thought I would comment on Colin Barker's piece in ZDnet
titled[SNW offers the frights
].The article starts out with an oversimplification:
The storage industry is enjoying a boom currently thanks to the requirement for IT managers to keep everything. With the possibility of being sued any time by any company for no good reason at all, everyone is keeping everything, or at least all their data. Result? Loads and loads more kit being bought to the benefit of EMC, IBM, HP and every other supplier with any kind of storage product.
While its true that IBM System Storage grew yet again in 3Q07, exceeding our own internal business model, I would not call this an overall "boom" for the storage industry. While companies are growing in "TB capacity" by 30-50%, this translates only to single digit growth in terms of "Dollar revenues". This is because we continue to make storage with declining dollar-per-GB.
One should not confuse what people do with what people are required to do. I am not a lawyer, but most regulations pertaining to storage of information state that certain records need to be kept for a set amount of time, either a fixed period of years, or based on some event. For example, broker/dealers need to keep emails of their clients for six years after the client closes their brokerage account. After those six years, the records can be destroyed.
Unfortunately, many IT managers look at the laws and come up with the simplest solution: keep everything forever. While this might meet the regulators audit requirements, it does expose their employer to subpoenas for data that should have been deleted, and may not be very cost-effective.
The alternative for many IT managers involves having to leave their comfort zone, and talk to their legal counsel, the lines of business, and try to classify their data, determine a set of policies, and inact some forms of enforcement. This is perhaps the "scary" part of the storage of information, it has grown outside the walls of IT, forcing IT managers to interact with the rest of the business to get their jobs done.
Compliance is the only game in town and that is most certainly where the money is.
Anytime an analyst tells you that something is the "only game in town", they are usually wrong. In this case, IBM has had great success in other areas that are not compliance-related. For example, digital video surveillance (DVS) is being used not only to help reduce shoplifting, but also to help identify patterns in customers perusing through aisles and window-shopping. Identifying what people are interested in has proven effective in moving product displays around to better attract buyers and motivate them to make purchases.
Take, the keynote from Andy Monshaw, general manager of IBM storage, and thus a man who is very much in a position to know. He spent his allotted 30 minutes, or whatever, listing all the security, compliance, threats and related issues that are currently making the jobs of most IT manager a cause for concern. Now, there is an argument that suggests that it is absolutely the right thing to do to frighten IT managers into sorting out their issues. They need shaking up say some. Especially analysts.
I helped develop the content of Andy's SNW presentation, working with his speech writers and graphic artists to make a consistent and coherent message fit in the 25 minutes he was given. The challenge with SNW is that we needed to make this presentation applicable across the entire storage industry, without sounding like an infomercial for IBM offerings.
Some people have compared the storage to the "insurance industry", claiming that backups, remote disk mirroring, continuous data protection and other storage related features are costs that can be compared to insurance you pay to protect your home, business, and other assets. You hope you never have to use it, and complain how much it costs, but when bad things happen, you hope it is the best money can buy.
Unlike Y2K, which was a one-time event that had a specific date of occurrence, the threats and risks mentioned by Andy in his presentation may never happen at all, or in other cases, may happen more than once, without knowing when or where. For the sake of your shareholders, and your stakeholders, it is best to be prepared for these possibilities.
The counter argument says that IT companies just smell the money.
Is this a counter argument? Can IBM not both help customers mitigate their risks, and at the same time, turn a profit? Trust me, you do not want to do business with any storage vendor that is not interested in making a profit. The better ones have incorporated addressing client's most pressing challenges into their strategy. I gave a quick summary of IBM's strategy last August in [Day 1 Storage Symposium].
Helping our clients mitigate risks is just one of IBM's core strengths. If you want to learn more, contact your local IBM Business Partner or storage rep.

Happy New Year, everyone!
I hope everyone had some time these past few weeks of the Winter Solstice to enjoy some time off with friends and family. I had a great trip to New York City, got to visit my brother and his friends, went to see my friends in Michigan to celebrate New Years Eve, and see the world premiere of [LexiBaby], an independent film from fellow filmmaker Jonathan Petro.
Talking to people in New York, Michigan and Arizona gave me some perspective on what 2008 was like for them, and what they anticipate for the new 2009 year. Borrowing the meme from last month's Freakonomics contest[Got Six Words to Inspire America] and the book[Not Quite What I Was Planning: Six-Word Memoirs by Writers Famous and Obscure], I can summarize the responses I heard into three groups:
- Sadly, life is full of disappointment
- In holding pattern, checking fuel level
- Am I dreaming? Someone pinch me!
The latter of course from fellow IBMers, corporate executives receiving bailout money, attorneys that specialize in foreclosures, and the lucky few who will be in Washington DC for the US Presidential Inauguration.In addition to all the bailout money from banks, insurance companies and automakers that will be spent on IBM equipment and services, there might be additional funds from the US Government to improve our country's information infrastructure.In a recent Forbes article titled[The Tech Solution To The Recession], Andy Greenberg writes about US president-elect Barack Obama's ideas about a stimulus to the economy. Here's an excerpt:
"IBM, for starters, believes that a massive infusion of cash should go toward cutting-edge technology. Last month, IBM CEO Sam Palmisano presented a report to Obama's transition team from the Information Technology and Innovation Foundation (ITIF) that argues that a $30 billion investment in universal broadband, health information technology and a smarter power grid could create 950,000 jobs.
"Those disparities, and IBM's argument for focusing a stimulus plan on technology in general, come from what economists have dubbed "network multipliers." The computing giant, and ITIF, argue that technology creates more jobs than other types of infrastructure by enabling new types of businesses.
"If you build more roads, people don't buy more tires or GPS systems, but if you build better networks, you create entirely new business applications," says Rob Atkinson, president of ITIF and an author of the think tank's report. "Something like YouTube could never have existed without broadband."
"Regardless of precisely how tech stimulus money gets spent, IBM will likely sweep up a significant chunk of those taxpayer funds, given the computing giant's diverse hardware, software and services businesses. Other IT infrastructure giants like Microsoft, Hewlett Packard, Oracle and SAP are also likely to vie for pieces of Obama's stimulus package aimed at technology.
"But among those tech companies, IBM has been especially active in driving home the need for national investment in tech systems. In a November speech to the Council on Foreign Relations, Palmisano argued that that the U.S. needs to invest in innovation not just as a solution to our current recession but as a competitive measure in an increasingly integrated and technologically advanced world."
The concept and advantages of network multipliers are not new. For more on this, read the whitepapers[Segmentation, Network Multipliers and Spillovers: A Theory of Rural Urban Migration for a Traditional Economy by Vegard Iversen, and [Network multipliers and the optimality of indirectcommunication] by Andrea Galeotti and Sanjeev Goyal.

This is page 34 of Sequoia Capital's[56-slide presentation] about the current financial meltdown. In the past, IT spending tracked closely to the rest of the economy, but the latest downturn has not yet reflected in IT spend.

Continuing my coverage of the IBM Systems Technical University in Orlando, here are the sessions that I presented or attended on Days 4 (Thursday).
- Technology Trends in IBM Storage
Jack Arnold, IBM Client Technical Architect, provide an entertaining session on various technology trends in the industry. For example, What is the fastest growing storage medium for 2015? Answer: [Vinyl LP] records, which have seen a resurgence recently, growing at over 40 percent!
- IBM Spectrum Scale and Elastic Storage Server offerings
Tony Pearson provided an architectural overview of both Spectrum Scale software, as well as the Elastic Storage Server pre-built system appliance.
- IBM Spectrum Scale for File and Object storage
Tony Pearson explained the differences between file and object-level storage, and how IBM Spectrum Scale can provide both access methods in a single infrastructure.
- IBM Storage Integration with OpenStack
- IBM Spectrum Virtualize IP Replication 101
Andrea Sipka, IBM Software Developer for SVC/Storwize Copy Services from the UK Hursley lab, presented the implementation details of IP-based replication using the built-in WAN Acceleration that IBM licensed from Bridgeworks SANslide.
- Storage Meet the Experts
Mo McCullough hosted the last session of Thursday with a "Meet the Experts" Q&A panel. Tony Pearson, Brian Sherman, Clod Barrera, John Wilkinson, Mike Griese and Jim Blue were among the storage experts fielding questions. Tony Pearson provided a quick overview of the LTO-7 and TS4500 tape library announcements made earlier in the week.
Most IBM conferences are 4.5 days long, which means that there are typically two or three sessions on Friday morning. Unfortunately, the two sessions I was planning to attend on Friday were both cancelled, so Day 4 was the end of my week for this conference.

I survived my first day at SNW Spring 2007
.This is my first time at SNW, but it is very much like many of the other conferences I have been to.It officially started Monday morning with pre-conferencetutorials and primer break-outsessions that covered storage fundamentals, but I didn't arrive until late Monday night due to highwind conditions at the Phoenix airport that delayed my travel.
Tuesday started out with main tent sessions. Ron Milton, VP of ComputerWorld that puts on this conference,and Vincent Franceschini, Chairman of the Board for SNIA, kicked off the event.It didn't take them long to get into the alphabet soup: ILM, ITIL, SMI-S, XAM, IMA, MMA, DDF,MF, DMF, IPSF, SSIF, and SRM.Several hundred people had "voting devices" so that they could participate in "informal" surveys.
Q1. What was the greatest need?
- 37% Storage Resource Management (SRM) tools
- 19% Storage Virtualization
- 19% Information Lifecycle Management (ILM)
- 14% Integration with other management tools
- 11% Compliance storage for regulations
Q2. What are people doing to address storage infrastructure complexity?
- 33% Deploying new SRM and SAN management tools
- 26% Adopting "Storage as a Service" methodology
- 22% Deploying new storage virtualization technologies
- 8% Hiring more staff
- 9% (complexity was not an issue)
The first keynote speaker was Cora Carmody, CIO of SAIC. In the late 1980s and early 1990s, I did a lot of work with SAIC here in San Diego, and so IBM sent me to San Diego quite frequentlyfor face-to-face meetings with them. Her talk was cryptically titled "Jumbo Shrimp, InformationManagement, and the Mark of the Beast." Coming up with good titles is important. Some of herkey points:
- "Information management" was as much an oxymoron as "jumbo shrimp" or "military intelligence".(SAIC is a general contractor for the US Military, so this was especially funny).
- Computer data needs both "ownership" and "stewardship".
- Gartner analyst reports that 50% of digital information for a business resides in personal files onindividual PCs.
- PAN-StaRRs project is ingesting 10TB per week of astronomical data.
- TeraTEXT(R) project is a non-relational database that supports a large mix of structured and unstructured content.
- The next "Y2K" crisis for the USA is changing from 3-digit to 4-digit area codes for our telephone numbers.
- Battery size and life have not advanced as fast as we need
- There has been little progress in "User Interface" ease of use
- Formats and standards are picked for the most part by the winning vendors, and it is the silence of themarketplace that lets them get away with this.
- We are overly reliant on an inherently insecure medium.
- The "mark of the beast" refers to exciting new technologies based on "presence awareness". For example,some hotels now are able to check you into the hotel as you drive up in your car, based on your car's licenseplate. Some 24-hour gyms use your fingerprint as your entry credentials, eliminating the need to staff peopleat the front desk.
IBM's own Barry Rudolph, presented "Storage in an Age of Inconvenient Truths", dressed up like Oscar-winner andformer USA Vice President Al Gore. Barry's focus was on the growingconcern of over environmental Power and Cooling issues in the data center. According to IDC, the cost of power and cooling an individual server, over its lifetime, now exceeds its acquisition cost. Storage devices are not as bad as servers in this regard. Data centers now consume 1.2% of the worlds energy.
Over lunch, I heard Tony Asaro from ESG present "The Need for Highly Virtualized Storage Systems withina Virtualized Data Center." His concern is that there is still a "heavy touch" required to manage storage.Without virtualization, your data center is less than the sum of its parts. Although IBM has been doingstorage virtualization since 1974, Tony mentioned that most storage vendors were "late to the party".He argues that "internal virtualization" inside storage arrays is not enough, you need "external virtualization"(like the IBM System Storage SAN Volume Controller) to virtualize your entire infrastructure.What storage administrators would like is for storage to have consumer levels of "ease of use", and today'snon-virtualized storage environments are nowhere near that.
"The great advantage [the telephone] possesses over every other form of electrical apparatus consists in the fact that it requires no skill to operate the instrument."
- Alexander Graham Bell, 1878
I attended a few break-out sessions in the afternoon.
- Ralph Wescott, Pacific Northwest National Library
Ralph presented "Crisis of Capacity" which covered the drastic actions he had to take to handle power and coolingin their expanding data center during their summer months, where temperatures peak up to 105 degrees. This included creating "hot" and "cold" aisles onhis raised floor by re-organizing the perforated floor tiles, and doing a better job standardizing how cables areconnected to the back of racks and up through the ceiling to maximize airflow. An amp-meter on each power strip was used to measure the powerused at each rack, which allowed them to better prioritize their efforts. Their Air Conditioning unit was only 12inches from the concrete floor, and raising it to 18 inches greatly reduced noise and vibration. Adding a second AC unit made a world of difference. Finally, they eliminatedKVMs, because people who use KVMs break other parts of thedata center. His rule of thumb: the cooling requirements will be 50% of the rated power requirements for equipment.
- Terry Yoshi, Intel internal IT department, as a member of the SNIA's end user council
Terry presented "Taming the SAN Complexity". The problem with "complexity" as a concept is that it is very subjective, difficult to quantify, and therefore difficult to manage. He presented complexity in four areas:Organizational structure of the company as a whole; skill sets required of the IT staff; business process andprocedures; and technology. Dealing with complexity is a battle between Old School (because we've always doneit this way) and New School (because it is new and different technology). Storage Area Networks are inherentlya "shared resource", and the increased complexity is a direct result of the low reliability of the componentsand devices it is composed of. People should focus on the "Total Cost of Ownership" (TCO) for a SAN, and not just the initial acquisitionprice of SAN gear.He was not a fan of the "dual/multiple" vendor strategy that many companies employto reduce costs. His suggestion that things should be tried out first on your "test SAN" caused some chuckles,as few have such a thing. Finally, he suggested not only documenting "Best Practices" and "Best Known Methods"but also things that have been found not to work, his do-not-try-this-at-home list.
- Tony Antony, Cisco marketing manager for Optical products
This was an overview of the technologies available for long distance connections for disaster recovery,business continuity, and resilience. He covered three levels.
His rule of thumb: one buffer credit for every kilometer at 2Gbps speed (for every 2km at 1Gbps).
- IP - Fibre Channel of IP (FCIP) offers the greatest "global" distance but forces people into asynchronous mirroring.
- SONET/SDH - SONET is what we call it in the USA, and SDH is what it is called in other countries. This provides state-to-state or "out-of-region" distances, which is ideal to meet certain government regulations for homeland defense. He suggests this is offered when dark fiber or DWDM is not available.
- DWDM/CWDM - this is using a prism to run multiple colors of light through a single fiber optic cable. CWDM ischeaper, but only handles 8 signals per cable. DWDM can handle 32 to 160 signals per cable, but is more expensive.
The day ended at the "Expo". I hung out at the IBM booth to help answer questions and network with others.

Last week, Paul Weinberg of eChannelLine.com asks Is this the year of the SAN (again)?
So, I thought this week I would cover my thoughts and opinions on storage networking. We oftenfocus on servers or storage devices, and forget that the network in between is an entire worldon itself.
I believe Mr. Weinberg is basing this on the idea that in 2007, over 50 percent of disk will beattached over SAN, edging out the alternative: Direct Attached Storage (DAS). But perhaps 50 percentis the wrong number to focus on. In 2007, The United Nations estimates thatcities will surpass rural areas, with just over 50 percent of theworld's population. Does that make this the "Year of the City"? Of course not.
Instead, I prefer to use the methodology that Malcolm Gladwell uses in his book, The Tipping Point.(I have read this book and highly recommend it!)Gladwell indicates that the tipping point happens at the start of the epidemic, not when it is half over.Isn't it better to celebrate the sweet 16 debutante ball when young ladies have completed their years of training and preparation, and are ready to be introduced to the rest of the world, rather than after they are thirty-something, married with children.
Let's explore some of the history. Stuart Kendric has a nice 7-page summary on theHistory & Plumbing of SANs.
IBM announced the first SAN technology calledEnterprise Systems Connection (ESCON) way back in September 1990. This allowed multiplemainframe servers to connect to multiple storage systems over equipment called "ESCON Directors" that directedtraffic from point A to point B. Before this, mainframes sent "ChannelCommand Words" or CCWs, across parallel "bus and tag" copper cables. ESCON was serial overfiber optic wiring. SANs solved two problems: first, it reduced the "rat's nest" of cables between many serversand many storage systems, and second, it extended the distance between server and storage device.
For distributed systems running UNIX or Windows, the CCW-equivalent over parallel cables was called Small ComputerSystem Interface (SCSI). The SCSI command had over 1000 command words, so for its Advanced Technology (AT) personal computers (PC AT), IBM introduced a subset of SCSI commands called ATA (Advanced Technology Attachment). ATA drives supportedfewer commands, ran at slower speeds, and were manufactured with a less rigorous process. Today ATA drives are about 55 percent the cost per MB as comparable SCSI drives.
Anyone who has ever opened their PC and found flat ribbon cable with eight or sixteen wires in parallel, can understand that the same issues applied externally. Parallel technologies arelimited to distance and speed, as all the bits have to arrive at the end of the wire at approximately thesame time. Direct attach schemes with every server attaches directly to every storage device were also problematic.Imagine 100 servers connected to 100 storage devices, that would be 10,000 wires!
So, a new technology standard was developed, called Fibre Channel, ratified in 1994.The spelling of "Fibre" was intentionally made different than "Fiber" on purpose. "Fibre" is a protocol thatcan travel over copper or glass wires. "Fiber" represents the glass wiring itself.
Fibre Channel is amazingly versatile. For today's Linux, UNIX and Windows servers, it can carry SCSI commands, and the combination of SCSI over FC is called Fibre Channel Protocol (FCP). For the mainframe servers, it can carry CCW commands. Running CCW over Fibre Channel is called FICON. This convergence allows mainframes and distributed systems to share a common Fibre Channel network, using the same set of switches and directors.
We saw the use of SANs explode in the marketplace over the past 10 years, and then cool down with a series of mergers and acquisitions. Last year, Brocade announced it was acquiring rival McData, so we will be down to two major players, Cisco and Brocade.
So, IMHO, I think we are well past the "Year of the SAN".

Continuing this week's theme on Storage Area Networks, today I thought I would talkabout the various terms we use for our equipment.
One area of confusion are the adjectives "entry-level", "midrange" and "enterprise-class".What do these mean? Well, as in the case of disk and tape, these three are all relative terms that are a combination of "small, medium, large" as well as "good, better, best".
- Entry-level switches are typically only a maximum of 8-16 ports.Ports can connect the switch to a server, a storage device, or another switch.These are sometimes called "edge" switches, as they might be found in the mostremote sections of an office campus, remote branches, or other isolated areasoutside the primary data center.
- Midrange switches typically have a maximum of 32-64 ports.More ports on a single switch means fewer switches (and fewer cables) to manage.
- These are called "directors" to distinguish them from entry-level and midrange offerings.Directors have a maximum of 140-528 ports, and because so many devices or switches can beconnected to them, they need to be extremely reliable. Directors are designed for 24x7operation, with the ability to make most upgrades and configuration changes while the boxis running (often referred to as "non-disruptive upgrades"). Availability is typically better than "five nines", or 99.999 percent, which means that the box will be up 99.999 percent of the time, or conversely, will be down lessthan 5 minutes per year.
If you are asking yourself "which size is right for my company?" or "is my company big enoughfor a director?" you are asking the wrong questions! Instead, determine a SAN configurationthat meets your workload, and then decide the components for that design.
McData coined a phrase called "core/edge" design that is considered today as "Best Practice" throughout the industry.A good write-up can be found here at SearchStorage.com. Basically, you put your big beefy "core" directors in the center of the room, and then surround it with midrange switches, that then these connect to "edge" switches, that then connect to the servers and storage near them. As you grow, this design can easilyscale to grow with you.
So, if you need help implementing a SAN for the first time, or upgrading the one you have,call IBM, we can help!

When I was a kid, I used to love old spy movies where they would hide a small microchip or microfiche behind the stamp on a letter or postcard. "Yeah right," I would think to myself, "how much information could that little thing possibly hold."On their post[Bringing the "New Intelligence" Down to Earth: Intro to Semantic Web, Internet-of-Thing
], My fellow IBM bloggers Jack Mason and Adam Christensen pointed me to a crazy new product called "Mir:ror" that connects to your PC or laptop.
At first, I thought it was a another product spoof, like Onion News Networks'video of the [Apple MacBook Wheel] that eliminatesthe need for a keyboard.But no, this product is real, from a company called [Violet]. The mir:ror, the internet-connected rabbits, and the tiny postage stamps called "ztamps" with embedded RFID chips that allow everything to be interconnected.I can see a lot of interesting uses for the ztamps. Squishing CD-romsor memory sticks inside presentation folders was always awkward. Butthese are small, flat and discrete. I don't know how many GBs of storage each ztamp holds, but they look cool, don't they?
Just another example of becoming a smarter planet!
