Of these, fellow blogger Marc Farley suggested for me "Tony Late for Dinner Pearson", which is fair, I guess, given that I often work late to make sure my blog posts are well written, and sometimes that means I am the last to leave the building.
Full Disclosure: I've known Marc for a while now, we have attended events together and even were co-speakers on a conference call for customers.
Perhaps more disturbing is that, for the most part, the storage blogosphere is entirely dominated by men. Where are the women bloggers for storage?
People are confused over various orders of magnitude. News of the economic meltdownoften blurs the distinction between millions (10^6), billions (10^9), and trillions (10^12).To show how different these three numbers are, consider the following:
A million seconds ago - you might have received your last paycheck (12 days)
A billion seconds ago - you were born or just hired on your current job (31 years)
A trillion seconds ago - cavemen were walking around in Asia (31,000 years)
That these numbers confuse the average person is no surprise, but that it confuses marketing people in the storage industry is even more hilarious. I am often correcting people who misunderstandMB (million bytes), GB (billion bytes) and TB (trillion bytes) of information.Take this graph as an example from a recent presentation.
At first, it looks reasonable, back in 2004, black-and-white 2D X-Ray images were only 1MBin size when digitized, but by 2010 there will be fancy 4D images that now take 1TB, representinga 1000x increase. What?When I pointed out this discrepancy, the person who put this chart together didn't know what to fix.Were 4D images only 1GB in size, or was it really a 1000000x increase.
If a 2D image was 1000 by 1000 pixels, each pixel was a byte of information, then a 3D imagemight either be 1000 by 1000 by 1000 [voxels], or 1000 by 1000 at 1000 frames per second (fps). Thefirst being 3D volumetric space, and the latter called 2D+time in the medical field, the rest of us just say "video".4D images are 3D+time, volumetric scans over time, so conceivably these could be quite large in size.
The key point is that advances in medical equipment result in capturing more data, which canhelp provide better healthcare. This would be the place I normally plug an IBM product, like the Grid Medical Archive Solution [GMAS], a blended disk and tape storage solution designed specifically for this purpose.
So, as government agencies look to spend billions of dollars to provide millions of peoplewith proper healthcare, choosing to spend some of this money on a smarter infrastructure can result in creating thousands of jobs and save everyone a lot of money, but more importantly, save lives.
Short 2-minute [video] argues the case for Smarter Healthcare
For more on this, check out Adam Christensen's blog post on[Smarter Planet], which points to a podcast byDr. Russ Robertson, chairman of the Counsel of Medical Education at Northwestern University’s Feinberg School of Medicine, and Dan Pelino, general manager of IBM's Healthcare and Life Sciences Industry.
An avid reader of this blog pointed me to a blog post [A Small Tec DIGG on IBM XIV], byGowri Ananthan, a System Engineer in Singapore.Basically, she covers past battles, er.. discussions between me and fellow blogger BarryB from EMC, and [blegs] foranswers to three questions.
Gowri, here are your answers:
Q1. Does IBM offer a Pay-as-you-Go [PAYGO] upgrade path for its IBM XIV disk storage system?
The concern was expressed as:
PAYGO also requires the customer to purchase the remaining capacity within 12 months of installation. So it is More of a 12-month installment plan than pay-as-you-grow.
A1. Actually, IBM offers several methods for your convenience:
With IBM's Capacity on Demand (CoD) plan, you get the full framewith 15 modules installed on your data center floor, but only pay for the first four modules 21 TB, then pay for 5.3TB module increments as you need them over the next 12 months. This is ideal for companies that don't know how fast they will grow, but do not want to wait for new modules to be delivered and installed when needed.
With IBM's Partial Rack offering, you can get a system with as little as six modules (27TB),and then over time, add more modules as you need. This does not have to be done within 12 months, you can stay at six modules for as long as you like, and you can take as long asyou want to add more modules. When you are ready for more capacity, the drawer or drawerscan be delivered, and installed non-disruptively.
Neither of these are "payment installment plans", but certainly if you want to spread yourcosts into regularly-scheduled monthlypayments across multiple years, IBM Global Financing can probably work something out.
Q2. Does IBM consider the XIV as green storage?
The concern was expressed as:
You are powering (8.4KW) and cooling all 180 drives for the whole duration, whether you're using the capacity or not. is it what you called Greener power usage..?
A2. Yes. IBM considers the IBM XIV as green storage. The 8.4KW per frame is lessthan the 10-plus KW that a comparable 2-frame EMC DMX-950 system would consume. Theenergy savings in IBM XIV comes from delivering FC-like speeds using slower SATA disks that rotate slower, and therefore take less energy to spin.
In the fully-populated or Capacity on Demand configuration, you would spin all 180disks. However, using the partial rack configuration, the 6-module has only 40 percent ofthe disks, and therefore consumes only 40 percent of the energy. If you don't plan to storeat least 20-30 TB, you might consider the DS3000, DS4000, DS5000, or DS8000 disk system instead.
Q3. How do you connect more than 24 host ports to an IBM XIV?
The concern was expressed as:
And finally do not forget my question on 24-FC Ports… Up to 24 Fiber Channel ports offering 4 Gbps, 2Gbps or 1 Gbps multi-mode and single-mode support.Stop.. stop.. how you gonna squeeze existing bunch of FC cables in 24 ports?
A3. Best practices suggest that if you have ten or more physical servers, each with two separate FC ports, then you should use a SAN switch or director in between. If you require four ports per server, then you would need a SAN switch beyond six servers to connect to the IBM XIV. If you consider that 24 FC ports, at 4Gbps, represents nearly 10 GB/sec of bandwidth, you will recognize that this is not a performance bottleneck for the system.
While the rest of Americans were glued to their televisions watching President Obama explain his plan for recovery, my colleagues and Ihad dinner with clients from Canada.
One in particular claimed her father was known as the kingpin of[Flin Flon]. She lives in Ontario now, but she grew up in this smallmining town in Manitoba made famous for winning a government contractto grow crops for medicinal purposes.
Shown at left is the town's mascott, Flinty. Yes, apparently thetown was named after a fictional character of a paperback novel.
Of course, in conversations with clients, it is best to avoid topics like politics or drugs,but the intersection of government health care and implications on IT can't be disregarded.Since Canada has a more efficient healthcare process, the government enjoys a lower costper citizen. President Obama has suggested that the United States should adopt reforms to make the American system more efficient, including electronic medical records.
Not surprisingly, [smarter healthcare] is part of IBM's latest set of strategic initiatives.Digitizing medical information has a variety of benefits:
Information isn't stranded on islands
If there is any situation that needs to deliver the right information, to the right people,at the right time, healthcare is certainly one of them. Having the right information canhelp reduce medical mistakes.
Physicians spend time with their patients, not paperwork
I personally know some doctors here in Tucson, and they are the first to admit that theywould prefer to focus on their core strengths, which they spent many years in medical school,and leave the administrative details to someone else. Focusing on core strengths is acommon theme for successful businesses, and this is no different.
Expertise needs no passport
Medical emergencies do not always happen near the hospital or clinic that your medical records are stored at.An exciting feature of digital information is that it is easy to transport to where it isneeded, unlike paper records or X-ray film.
