I have arrived safely in Las Vegas for the IBM System Storage and Storage Networking Symposium. This eventis held once every year. The gold sponsors were: Brocade, Cisco, Finisar, Servergraph, and VMware. Our silversponsor was Qlogic.
I presented IBM's System Storage strategy and an overview of our product line. For those who missed it,our strategy is focused on helping customers in four key areas:
Optimize IT - to simplify and automate your IT operations and optimize performance and functionality, through server/storage synergies, storage virtualization, and intergrated storage infrastructure management.
Leverage Information - to enable a single view of trusted business information through data sharing, and to get the most value from information through Information Lifecycle Management (ILM).
Mitigate Risk - to comply with security and regulatory requirements, and keep your business running with a complete set of business continuity solutions. IBM offers a range of non-erasable, non-rewriteable storage, encryption on disk and tape, and support for IT Infrastructure Library (ITIL) service management disciplines.
Enable Business Flexibility - to provide scalable solutions and protect your IT investment through the use of open industry standards like Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). IBM offers scalability in three dimensions: Scale-up, Scale-out, and Scale-within.
IBM has a broad storage portfolio, in seven offering categories:
Disk Systems, including our SAN Volume Controller, DS family, and N series.
Tape Systems, including tape drives, libraries and virtualization.
Storage Networking, a complete set of switches, directors and routes
Infrastructure Management, featuring the IBM TotalStorage Productivity Center software
Business Continuity, advanced copy services and the software to manage them
Lifecycle and Retention, our non-erasable, non-rewriteable storage including DR550, N series with SnapLock, and WORM tape support, Grid Archive Manager and our Grid Medical Archive Solution (GMAS)
Storage Services, everything from consulting, design and deployment to outsourcing and hosting.
I could talk all day on this, but given that the room was packed, every seat taken and the rest of the audience standing along the walls, I had to keep it down to one hour.
SAN Volume Controller Overview
I presented an overview of the IBM System Storage SAN Volume Controller (SVC), IBM's flagship disk virtualizationproduct. Rather than giving a long laundry list of features and benefits,I focused on the five that matter most:
Reduces the cost and complexity of managing storage, especially for mixed storage environments
Simplifies Business Continuity through non-disruptive data migration and advanced copy services
Improves storage utilization, getting more value from the storage hardware you already have
Enhances personnel productivity, empowering storage administrators to get their job done
Delivers high availability and performance
SAN Volume Controller - Customer Success Stories
A good part of this conference are presented by non-IBMers, which include Business Partners and clientssharing their experiences. In this session, we had two speakers share their experiences with SVC.
David Snyder keeps over 80 web sites online and available. His digital media technologiesteam uses SVC to make their storage administration easier, and ensure high availability for web site content creation and publishing.
Mark Prybylski manages storage at his company, a financial bank. His storage management team uses SVC Global Mirror which provides asynchronous disk mirroring between different types of disk, as part oftheir Business Continuity/Disaster Recovery plan.
The last session I attended was "Storage .. to Optimize your ECM depoloyments" by Jerry Bower, now working for IBM as part of our recent acquisition of the Filenet company. ECM stands for Enterprise Content Management, and IBM is the market leader in this space. Jerry gave a great overview of IBM Content Manager software suite, our newly acquired Filenet portfolio, and the storage supported.
After the sessions was a reception at the Solution Center with dozens of exhibitor booths. For example,Optica Technologies had their PRIZM productswhich are able to connect FICON servers to ESCON storage devices.
The proof-of-concept that IBM Haifa research center developed back in 1998 became what we now call the iSCSI protocol.The book iSCSI: The Universal Storage Connection introduces the history as follows:
In the fall of 1999 IBM and Cisco met to discuss the possibility of combining their SCSI-over-TCP/IP efforts. After Cisco saw IBM's demonstration of SCSI over TCP/IP, the two companies agreed to develop a proposal that would be taken to the IETF for standardization.
There are three ways to introduce iSCSI into your data center:
Through a gateway, like the IBM System Storage N series gateway, that allows iSCSI-based servers connect to FC-based storage devices
Through a SAN switch or director, a FC-based server can access iSCSI-based storage, an iSCSI-based server accessing FC-based storage, or even iSCSI-based servers attaching to iSCSI-based storage.
Directly through the storage controller.
IBM has been delivering the first method with its successful IBM System Storage N series gateway products, buttoday we have announced additional support for the second and third methods.Here's a quick recap.
New SAN director blades
Supporting the second method, IBM TotalStorage SAN256B Director is enhanced to deliver iSCSI functionality with a new M48 iSCSI Blade, which includes 16 ports (8 Fibre Channel ports; and 8 Ethernet ports for iSCSI connectivity). We also announced a new Fibre Channel M48 Blade which provides 10 Gbps Fibre Channel Inter Switch Link (ISL) connectivity between SAN256B Directors.
With support for Boot-over-iSCSI, diskless rack-optimized and blade servers can boot Windows or Linux over Ethernet,eliminating the management hassles with internal disk.
All of this is part of IBM's overall push into the Small and Medium size Business marketplace, making it easier to shop for and buy from IBM and its many IBM Business Partners, easier to deploy and install storage, and easier tomanage the storage once you have it.
Last week, a writer for a magazine contacted us at IBM to confirm a quote that writing a Terabyte (TB) on disk saves 50,000 trees. I explained that this was cited from UC Berkeley's famousHow Much Information? 2003 study.
To be fair, the USA Today article explains that AT&T also offers "summary billing" as well as "on-line billing", but apparently neither of these are the default choice. I can understand that phone companies send out bills on paper because not everyone who has a phone has internet access, but in the case of its iPhone customers, internet access is in the palm of your hands! Since all iPhone customers have internet access, and AT&T knows which customers are using an iPhone, it would make sense for either on-line billing or summary billing to be the default choice, and let only those that hate trees explicitly request the full billing option.
Sending a box of 300 pages of printed paper is expensive, both for the sender and the recipient. This informationcould have been shipped less expensively on computer media, a single floppy diskette or CDrom for example. Forthose who prefer getting this level of detail, a searchable digitized version might be more useful to the consumer.
Which brings me to the concept of Information Lifecycle Management (ILM). You can read my recent posts on ILM byclicking the Lifecycle tab on the right panel, or my now infamous post from last year about ILM for my iPod.
His recollection of the history and evolution of ILM fairly matches mine:
The phrase "Information Lifecycle Management" was originally coined by StorageTek in early 1990s as a way to sell its tape systems into mainframe environments. Automated tape libraries eliminated most if not all of the concerns that disk-only vendors tout as the problem with manual tape. I began my IBM career in a product now called DFSMShsm which specifically moved data from disk to tape when it no longer needed the service level of disk. IBM had been delivering ILM offerings since the 1970s, so while StorageTek can't claim inventing the concept, we give them credit for giving it a catchy phrase.
EMC then started using the phrase four years ago in its marketing to sell its disk systems, including slower less-expensive SATA disk. The ILM concept helped EMC provide context for the many acquisitions of smaller companies that filled gaps in the EMC portfolio. Question: Why did EMC acquire company X? Answer: To be more like IBM and broaden its ILM solution portfolio.
Information Lifecycle Management is comprised of the policies, processes,practices, and tools used to align the business value of information with the mostappropriate and cost effective IT infrastructure from the time information isconceived through its final disposition. Information is aligned with businessrequirements through management policies and service levels associated withapplications, metadata, and data.
Whitepapers and other materials you might read from IBM, EMC, Sun/StorageTek, HP and others will all pretty much tell you what ILM is, consistent with this SNIA definition, why it is good for most companies, and how it is not just about buying disk and tape hardware. Software, services, and some discipline are needed to complete the implementation.
While the SNIA definition provides a vendor-independent platform to start the conversation, it can be intimidatingto some, and is difficult to memorize word for word.When I am briefing clients, especially high-level executives, they often ask for ILM to be explained in simpler terms. My simplified version is:
Information starts its life captured or entered as an "asset" ...
This asset can sometimes provide competitive advantage, or is just something needed for daily operations. Digital assets vary in business value in much the same way that other physical assets for a company might. Some assets might be declared a "necessary evil" like laptops, but are tracked to the n'th degree to ensure they are not lost, stolen or taken out of the building. Other assetsare declared "strategically important" but are readily discarded, or at least allowed to walk out the door each evening.
... then transitions into becoming just an "expense" ...
After 30-60 days, many of the pieces of information are kept around for a variety of reasons. However, if it isn'tneeded for daily operations, you might save some money moving it to less expensive storage media, throughless expensive SAN or LAN network gear, via less expensive host application servers. If you don't need instantaccess, then perhaps the 30 seconds or so to fetch it from much-less-expensive tape in an automated tape librarycould be a reasonable business trade-off.
... and ends up as a "liability".
Keeping data around too long can be a problem. In some cases, incriminating, and in other cases, just having toomuch data clogs up your datacenter arteries. If not handled properly within privacy guidelines, data potentially exposes sensitive personal or financial information of your employees and clients. Most regulations require certain data to be kept, in a manner protected against unexpected loss, unethical tampering, and unauthorized access, for a specific amount of time, after which it can be destroyed, deleted or shredded.
So ILM is not just a good idea to save a company money, it can keep them out of the court room, as well as help save the environment and not kill so many trees. Now that 100 percent of iPhone customers have internet access, and a goodnumber of non-iPhone customers have internet access at home, work, school or public library, it makes sense for companies to ask people to "opt-in" to getting their statements on paper, rather than forcing them to "opt-out".
The IBM Storage and Storage Networking Symposium in Las Vegas continues ...
N series and VMware
Jeff Barnett presented how VMware manages disk image files in its VMfs repository, and how N series offersa better alternative. Virtual machines can access N series volumes directly.
Business Continuity with System i
Allison Pate presented the various Business Continuity options for System i. Many customersuse internal storage for System i, but this then hampers Business Continuity efforts. Instead,you can have IBM System Storage DS8000 or DS6000 series disk systems provide disk mirroringbetween clustered systems.
There was a lot of interest in DR550, one of our many compliance storage solutions. Ron Henkhauspresented an overview of our DR550 and DR550 Express offerings. Unlike the competitive disk-onlysolutions, such as the EMC Centera, the DR550 allows you to attach an automated tape library, managing large amounts of fixed content data at a much lower cost point. It also has encryption, for both diskand tape data.
Open Systems Disk Management
Siebo Friesenborg presented the various steps needed to troubleshoot performance problemswith open systems, including the use of "iostat" on AIX systems as an example, and the stepsyou can take to make formal Service Level Agreements (SLA) between the IT department and thevarious lines of business.
IBM Encryption - TS1120 and LTO-4 encryption comparison
Tony Abete presented TS1120 and LTO-4 encryption techniques. Deploying encryption is more thanjust choosing a tape drive. There are a variety of factors involved, such as whether to managethe keys from the application, the operating system, or the library manager. You need policiesto decided when to encrypt tapes and when not to, generating your keys, storing them, and sharingthem with your business partners, suppliers and service providers with which you send tapes.
I can tell that many people are feeling like they are "drinking from a firehose".IBM's success in storage reaches out to so many different aspects of information management,a variety of industries, and disciplines as varied as regulatory compliance and medical imaging.
If you are ever down in Sao Paulo, Brazil, may I suggest not drinking "American amounts" of their "Brazilian Coffee". The coffee here is "robust", to say the least.
Yesterday, my blog focused on IBM iSCSI offerings that were announced in August.Also announced earlier this month, the Integrated Removable Media Manager (IRMM) on System zhas been years in the making.IRMM is a new robust systems management product for Linux® on IBM System z™ that manages open system media in heterogeneous distributed environments and virtualizes physical tape libraries. IRMM combines the capacity of multiple heterogeneous libraries into a single reservoir of tape storage that can be managed from a central point.By providing an integrated solution with the opportunity for both mainframe z/OS DFSMSrmm and distributed Tivoli® Storage Manager™ environments to be managed by IRMM, System z can now be a hub for the management of removable media.
The people who thought the "Mainframe is obsolete", and those that thought "Tape is dead", are both proven wrong again with this announcement. People are looking to deploy robust tape automation for backup and archive, and this convergence with mainframe makes perfect sense by providing business value that extends to other distributed systems.
