The technology industry is full of trade-offs. Take for example solar cells that convert sunlight to electricity. Every hour, more energy hits the Earth in the form of sunlight than the entire planet consumes in an entire year. The general trade-off is between energy conversion efficiency versus abundance of materials:
IBM has eliminated this trade-off with a record-setting breakthrough last week, demonstrating 9.6 percent efficiency [thin film solar cells using earth-abundant materials].
A second trade-off is exemplified by EMC's recent GeoProtect announcement. This appears similar to the geographic dispersal method introduced by a company called [CleverSafe]. The trade-off is between the amount of space to store one or more copies of data and the protection of data in the event of disaster. Here's an excerpt from fellow blogger Chuck Hollis (EMC) titled ["Cloud Storage Evolves"]:
Seized by the government? falling into the wrong hands? Is EMC positioning ATMOS as "Storage for Terrorists"? I can certainly appreciate the value of being able to protect 6PB of data with only 9PB of storage capacity, instead of keeping two copies of 6PB each, the trade-off means that you will be accessing the majority of your data across your intranet, which could impact performance. But, if you are in an illicit or illegal business that could have a third of your facilities "seized by the government", then perhaps you shouldn't house your data centers there in the first place. Having two copies of 6PB each, in two "friendly nations", might make more sense.
(In reality, companies often keep way more than just two copies of data. It is not unheard of for companies to keep three to five copies scattered across two or three locations. Facebook keeps SIX copies of photographs you upload to their website.)
ChuckH argues that the governments that seize the three nodes won't have a complete copy of the data. However, merely having pieces of data is enough for governments to capture terrorists. Even if the striping is done at the smallest 512-byte block level, those 512 bytes of data might contain names, phone numbers, email addresses, credit cards or social security numbers. Hackers and computer forensics professionals take advantage of this.
You might ask yourself, "Why not just encrypt the data instead?" That brings me to the third trade-off, protection versus application performance. Over the past 30 years, companies had a choice, they could encrypt and decrypt the data as needed, using server CPU cycles, but this would slow down application processing. Every time you wanted to read or update a database record, more cycles would be consumed. This forced companies to be very selective on what data they encrypted, which columns or fields within a database, which email attachments, and other documents or spreadsheets.
An initial attempt to address this was to introduce an outboard appliance between the server and the storage device. For example, the server would write to the appliance with data in the clear, the appliance would encrypt the data, and pass it along to the tape drive. When retrieving data, the appliance would read the encrypted data from tape, decrypt it, and pass the data in the clear back to the server. However, this had the unintended consequences of using 2x to 3x more tape cartridges. Why? Because the encrypted data does not compress well, so tape drives with built-in compression capabilities would not be able to shrink down the data onto fewer tapes.
(I covered the importance of compressing data before encryption in my previous blog post [Sock Sock Shoe Shoe].)
Like the trade-off between energy efficiency and abundant materials, IBM eliminated the trade-off by offering compression and encryption on the tape drive itself. This is standard 256-bit AES encryption implemented on a chip, able to process the data as it arrives at near line speed. So now, instead of having to choose between protecting your data or running your applications with acceptable performance, you can now do both, encrypt all of your data without having to be selective. This approach has been extended over to disk drives, so that disk systems like the IBM System Storage DS8000 and DS5000 can support full
Certainly, something to think about!

Continuing my drawn out coverage of IBM's big storage launch of February 9, today I'll cover the IBM System Storage TS7680 ProtecTIER data deduplication gateway for System z.
On the host side, TS7680 connects to mainframe systems running z/OS or z/VM over FICON attachment, emulating an automated tape library with 3592-J1A devices. The TS7680 includes two controllers that emulate the 3592 C06 model, with 4 FICON ports each. Each controller emulates up to 128 virtual 3592 tape drives, for a total of 256 virtual drives per TS7680 system. The mainframe sees up to 1 million virtual tape cartridges, up to 100GB raw capacity each, before compression. For z/OS, the automated library has full SMS Tape and Integrated Library Management capability that you would expect.
Inside, the two control units are both connected to a redundant pair cluster of ProtecTIER engines running the HyperFactor deduplication algorithm that is able to process the deduplication inline, as data is ingested, rather than post-process that other deduplication solutions use. These engines are similar to the TS7650 gateway machines for distributed systems.
On the back end, these ProtecTIER deduplication engines are then connected to external disk, up to 1PB. If you get 25x data deduplication ratio on your data, that would be 25PB of mainframe data stored on only 1PB of physical disk. The disk can be any disk supported by ProtecTIER over FCP protocol, not just the IBM System Storage DS8000, but also the IBM DS4000, DS5000 or IBM XIV storage system, various models of EMC and HDS, and of course the IBM SAN Volume Controller (SVC) with all of its supported disk systems.Here is the [Announcement Letter]
It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
technorati tags: , announcements, IBM, Pulse, conference, TSM, Tivoli, SSAM, backup, archive, VMware, VCB, Hyper-V, Microsoft, SSL, AES, encryption, in-flight, Linux, HP-UX, Solaris, ERP, DB2, Oracle, RMAN, SAP, BR*Tools, ibm-pulse, pulse2010
Continuing my series of posts on the IBM Storage launch of February 9, I cover some new disk options.
Next week, I'll continue to chip away, bit by bit, at this huge storage launch.

What is IBM SONAS? It’s many things, so let’s start with this list:
IBM SONAS makes automated tiered storage achievable and realistic at petabyte levels:
And we’re just scratching the surface. IBM has plans to deploy additional protocols, storage hardware options, and software features.
However, the real question of interest should be, “who really needs that much storage capacity and throughput horsepower?”
The answer may surprise you. IMHO, the answer is: almost any modern enterprise that intends to stay competitive. Hmmm…… Consider this: the reason that IT exists today is no longer to simply save cost (that may have been true 10 years ago). Everyone is reducing cost… but how much competitive advantage is purchased through “let’s cut our IT budget by 10% this year”?
Notice that in today’s world, there are (many) bright people out there, changing our world every day through New Intelligence Competitive Advantage analytics-based IT applications such as real time GPS traffic data, real time energy monitoring and redirection, real time video feed with analytics, text analytics, entity analytics, real time stream computing, image recognition applications, HDTV video on demand, etc. Think of how GPS industry, cell phone / Twitter / Facebook, iPhone and iPad applications, as examples, are creating whole new industries and markets almost overnight.
Then start asking yourself, “What's behind these Competitive Advantage IT applications – as they are the ones that are driving all my storage growth? Why do they need so much storage? What do those applications mean for my storage requirements?”
( Read more about Analytics, pages 14-48 of [New Intelligence for a Smarter Planet - Driving Business Innovation with IBM Analytic Solutions] )
To be “real-time”, long-held IT paradigms are being broken every day. Things like “data proximity”: we can no longer can extract terabytes of data from production databases and load them to a data warehouse – where’s the “real-time” in that? Instead, today’s modern analytics-based applications demand:
This is a major paradigm shift in storage – and that is the solution and storage capabilities that IBM SONAS is designed to address. And of course, you should be able to save significant cost through the SONAS global virtual file server consolidation and virtualization as well.
Certainly, this topic warrants more discussion. If you found it interesting, contact me, your local IBM Business Partner or IBM Storage rep to discuss Competitive Advantage IT applications and SONAS further.
