Dan Galvan, IBM VP of Marketing for Storage, was the next speaker. With 300 billion emails being sent per day, 4.6 billion cell phones in the world, and 26 million MRIs per year, there is going to be a huge demand for file-based storage. In fact, a recent study found that file-based storage will grow at 60 percent per year, compared to 15 percent growth for block-based storage.
Dan positioned IBM's Scale-out Network Attached Storage (SONAS) as the big "C:" drive for a company. SONAS offers a global namespace, a single point of management, with the ability to scale capacity and performance tailored for each environment.
The benefits of SONAS are great. We can consolidate dozens of smaller NAS filers, we can virtualize files across different storage pools, and increase overall efficiency.
Powering advanced genomic research to cure cancer
The next speaker was supposed to be Bill Pappas, Senior Enterprise Network Storage Architect, Research Informatics at [St. Jude Children’s Research Hospital]. Unfortunately, St. Jude is near the flooding of the Mississippi river, and he had to stay put. An IBM team was able to capture his thoughts on video that was shown on the big screen.
Thanks to the Human Genome project, St. Jude is able to cure people. They see 5700 patients per year, and have an impressive 70 percent cure rate. The first genetic scan took 10 years, now the technology allows a genome to be mapped in about a week. Having this genomic information is making vast strides in healthcare. It is the difference of fishing in a river, versus putting a wide net to catch all the fish in the Atlantic ocean all at once.
Recently, St. Jude migrated 250 TB of files from other NAS to an IBM SONAS solution. The SONAS can handle a mixed set of workloads, and allows internal movement of data from fast disk, to slower high-capacity disk, and then to tape. SONAS is one of the few storage systems that supports a blended disk-and-tape approach, which is ideal for the type of data captured by St. Jude.
IBM's own IT transformation
Pat Toole, IBM's CIO, presented the internal transformation of IBM's IT operations. He started in 2002 in the midst of IBM's effort to restructure its process and procedures. They identified four major data sources: employee data, client data, product data, and financial data. They put a focus to understand outcomes and set priorities.
The result? A 3-to-1 payback on CIO investments. This allowed IBM to go from server sprawl to consolidated pooling of resources with the right levels of integration. In 1997, IBM had 15,000 different applications running across 155 separate datacenters. Today, they have reduced this down to 4,500 applications and 7 datacenters. Their goal is to reduce down to 2,225 applications by 2015. Of these, only 250 are mission critical.
Pat's priorities today: server and storage virtualization, IT service management, cloud computing, and data-centered consolidation. IBM runs its corporate business on the following amount of data:
9 PB of block-based storage, SVC and XIV
1 PB of file-based storage, SONAS
15 PB of tape for backup and archive
Pat indicated that this environment is growing 25 percent per year, and that an additional 70-85 PB relates to other parts of the business.
By taking this focused approach, IBM was able to increase storage utilization from 50 to 90 percent, and to cut storage costs by 50 percent. This was done through thin provisioning, storage virtualization and pooling.
Looking forward to the future, Pat sees the following challenges: (a) that 120,000 IBM employees have smart phones and want to connect them to IBM's internal systems; (b) the increase in social media; and (c) the use of business analytics.
After the last session, people gathered in the "Hall of the Universe" for the evening reception, featuring food, drinks and live music. It was a great day. I got to meet several bloggers in person, and their feedback was that this was a very blogger-friendly event. Bloggers were given the same level of access as corporate executives and industry analysts.
During the break, I talked with some of the other bloggers at this event. From left to right: Stephen Foskett [Pack Rat] blog, Devang Panchigar [StorageNerve], and yours truly, Tony Pearson. (Picture courtesy of Stephen Foskett)
Meet the Experts
This next segment was a Q&A panel, with a moderator posing questions to four experts. Originally, I was scheduled to be the moderator, but this was changed to Doug Balog. The experts on the panel were:
Rich Castagna, Editorial Director for Storage Media, TechTarget. TechTarget is the group that runs the [SearchStorage] website.
Stan Zaffos, Gartner VP of Research, who spoke earlier today. I have worked with Stan for years as well, and have attended the last four Gartner Data Center Conferences held every December in Las Vegas.
Steve Duplessie, Founder and Senior Analyst, Enterprise Strategy Group (ESG). Steve's blog is titled [The Bigger Truth].
Jon clarified a statement Doug Balog said earlier in the day attributed to his study. Doug had said that 40 percent of all data should be archived. The study that Jon Toigo had done found that, on average, for the data on disk systems, about 30 percent is useful data, 40 percent is not active and could be eligible for archive, and the remaining 30 percent was crap.
The other experts introduced themselves. Rich felt that "Cloud" was still the biggest buzzword in the IT industry. Stan felt that CIOs should ask their storage administrators "What are you doing to improve my agility and efficiency". Steve felt that it was better to focus on improving process and procedures, rather than trying to deploy the best technology.
How can you best reduce backup costs per TB?
Jon- use tape.
Rich- Clean up your environment.
Stan- Don't rehydrate your deduplicated data, adopt archive approach, and revisit your backup schedules.
Steve- Deduplication covers up stupidity. No band-aids! Companies need to address the cause.
Does Backup as a Public Service for large enterprises makes sense?
Rich- Yes, especially for those with Remote Office/Branch Office (ROBO).
Stan- It depends. You should implement client-side dedupe. Get the Cloud Provider to waive telecom bandwidth charges.
Steve- Consider recovery scenarios, and try to maintain control.
Jon- "Clouds" are bulls@#$ marketing. WAN latency will pile up.
What are the top issues IT leaders should be discussing with the Storage Managers?
Stan- To ensure SLAs meet but not exceed design, to automate, and to evaluate SAN/NAS ratios.
Steve- Server virtualization is putting the spotlight on storage. Failure to implement storage virtualization is becoming the gate that slows down sever virtualization adoption.
Jon- Insist on management features from all storage vendors, try to separate feature/function from the underlying hardware layer. See IBM's [Project Zero].
Rich- Efficiency, Archiving, Thin Provisioning, Compression, Data Protection & Retention, Backup Redesign to protect endpoints like laptops and cell phones.
When does Archive eliminate Backup?
The need for protection never goes away. There are two kinds of data: "originals" and "derivatives", and two kinds of disk: "failed" and "not yet failed".
Given SATA and SAS drives, what is the future of 10K/15K RPM drives?
There is no future for these faster drives, they are going away.
What is the biggest challenge for adopting archive?
It is easy to move data out of production systems, but difficult to make these archives accessible for eDiscovery and Search. There is also concern about changing data formats. Adobe has changed the format of PDF a whopping 33 times.
This was by far the most entertaining section of the day! Hand-held devices allowed the audience to vote which answers they liked best.
Doug Balog, IBM VP and Business Level Executive for Storage, presented Smart Archiving. Citing research by Jon Toigo, Doug indicated that 40 percent of data on disk should be archived. Sadly, a vast majority of companies continue to use their backups as archives. There is a better way to do archives, to address the needs of four use cases:
The IBM Information Archive for email, files and eDiscovery offers full text indexing. A well-deployed archive strategy can save up to 60 percent in backup costs, and reduce backup times by 80 percent. IBM offers advanced analytics and visualization for archive data.
An analysis of a global insurance company found that they kept, on average, 120 copies of every email sent. This was the combination of an average of 12 copies of the email, multipled by 10 backups of the email repository.
Banjercito, a bank in Mexico, has a 10-year retention requirement from government regulations.
The new LTFS Library Edition allows Library-based access to files stored on tape cartridges. The new TS3500 Library Connector means that a single system of connected tape libraries can hold up to 2.7 Exabytes (EB) of data.
Archive Industry Perspectives
Steve Duplessie from Enterprise Strategy Group [ESG] gave his views on the challenges of volume, access and cost. His definition for archive: the long term retention of information on a separate environment for compliance, eDiscovery and business reference purposes. Steve advocates a purpose-built solutiion for archive. There are three major challenges for implementing an archive solution:
Getting Participation -- Steve feels that key stakeholders have inappropriate expectations of what archive is, or can be.
Define Tasks -- Steve argues that archive is very much a process-oriented approach, and tasks must fit business process and procedures
Prepare for Future Content Types -- the frequent change of standard and proprietary data types poses a real challenge for long term retention of data
For example, the Financial Industry Regulatory Authority [FINRA] oversee 4,000 brokerage firms, and 600,000 broker/dealers. They have mandated the storing of digital data related to stock trades, and this can include text messages, voice messages, and emails. They continue to expand this definition, so soon this could include tweets on Twitter, for example.
Steve feels there are four key requirements for archive:
Support for email, such as an email application plug-in
Off-line access to archived data
Support for mobile devices, such as smartphones
Basic search capabilities
Companies are starting to take archive seriously. About 35 percent of firms surveyed have adopted archive, and another 36 percent plan to in the next 12-24 months. Enterprise archive has grown over 200 percent from 2007 to 2009. Steve agrees that not everything needs to be stored on disk. Retention periods greater than six years dictates the need for tape.
Current systems may not meet today's requirements. Data loss and downtime costs have skyrocketed. Data Protection and Retention projects can represent a gold mine of savings, new capabilities can greatly lower costs, allowing companies to shift resources over to revenue generation.
Big Data, New Physics and Geospatial Super-Food
I would vote this the best session of the day! For all those confused on what the heck "Big Data" means, Jeff has the best explanation. Jeff Jonas is an IBM Distinguished Engineer and the Chief Scientist of Entity Analytics. He had just finished his 17th marathon on Saturday, and his fingers were bandaged.
Jeff had founded the Systems Research and Design (SR&D) company, known for creating NORA (non-obvious relationship awareness) used by Las Vegas casinos to identify fraud. SR&D was acquired by IBM back in 2005. Jeff is focused on sensemaking of streams. He feels many companies are suffering from "Enterprise Amnesia".
"The data must find the data .. and the relevance must find the user."
-- Jeff Jonas
Jeff's metaphor to Big Data is a jigsaw puzzle without the picture on the outside of the box. To demonstrate his point, he presented a pile of jigsaw puzzle pieces and asked four teenagers to put the puzzle together without the advantage of the picture on the box. What he had not told them was that he mixed four different puzzles together, removing out 10 to 20 percent of the pieces from each puzzle. He also added some duplicate pieces from a second identical puzzle, and just to make things fun, included a dozen pieces from a sixth puzzle just to mess with their heads. Within a few hours, the kids had managed to figure out that there were four puzzles, that there were duplicate pieces, and that there were some pieces that did not fit any of the four puzzles.
"You can't squeeze knowledge from a pixel."
-- Jeff Jonas
This approach favors false negatives. New observations reverse out old conceptions. As the picture emerges, this provides added focus on new information. More data can provide better predictions. "Bad" data, including misspelled words and mis-coded categories, was often discarded or corrected on the basis of "Garbage-In, Garbage Out", but can now be useful in a Big Data perspective.
Take for example the 600 billion recordings of the "location data" captured on cell phones every day. With regular triangulation of cell phone towers, the information can pinpoint you within 60 meters, add GPS and this improved to within 20 meters, and add Wi-Fi is further improved to 10 meters. While this data is "de-identified" so as not to identify individual users, the process of re-identification is relatively trivial. Jeff's system is able to predict a person will be next Thursday at 5:35pm with 87 percent accuracy.
Thus, Big Data represents an asset, accumulation of context. Real-time analytics can be a competitive advantage. These streams of data will need persistent storage and massive I/O capabilities. In one example, Jeff processed 4,200 separate sources of information and was able to identify "dead votes". These are votes cast by people that died in years prior, indicating voter fraud.
Jeff's latest project, codenamed G2, will tackle not just people, but everything from proteins to asteroids.
Normally, the worst time slot is the hour after lunch, but these presentations kept people's attention.
Down the street, in Times Square, IBM made it on the big board.
Continuous Data Availability
Jeanine Cotter, IBM VP for Data Center Services, started out with a video about Sabre. IBM developed this revolutionary airline reservation system to handle the huge volume of transactions. Today, 18 percent of organizations consider downtime unacceptable for their tier-1 applications, and 53 percent would be seriously impacted by an outage lasting an hour or more.
Eventually, companies cross the "Continuous Availability" threshold, the point where they discover that the possibility of downtime is too costly to ignore. IBM has clients using 3-site Metro/Global Mirror that can fail-over an entire data center in just five mouse clicks.
Jeanine also mentioned Euronics, which is using SAN Volume Controller's Stretched Cluster capability, which allows them to easily vMotion virtual guest images from one data center to another. SVC has had this capability for a while, but now, with full VMcenter plug-in and VAAI support, the capability is fully integrated with VMware.
A final example was a mid-sized University, they are using IBM Storwize V7000 with Metro Mirror. The primary location's Storwize V7000 manages Solid-state drives with Easy Tier. The secondary location's Storwize V7000 has high-capacity SATA drives and FlashCopy.
Customer Testimonial - University of Rochester Medical Center
Rick Haverty, Director of IT infrastructure at University of Rochester Medical Center [URMC] provided the next client testimonial. The mission of the URMC is to use science, education and technology to improve health. URMC gets over $400 million USD in NIH grants, which puts them around 23rd largest University-based academic medical centers in the country. They have over 900 doctors, general practice and specialists.
URMC has an IBM BlueGene supercomputer, a Cisco network over 45,000 ports, and over 7.5 million square feet of Wi-Fi wireless internet coverage. They have three datacenters. The first is 7500 square feet, the second is 6000 square feet, and the third is just 800 square feet to hold their "off-site tapes".
URMC has digitized all of their records, including Electronic Medical Records (EMR) system, medical dosage history, imaging "priors", calibration of infusion pumps, RFID monitoring, and even provide IT support while the patient is on the operating table. RFID monitoring ensures all of the refrigerators are keeping medications at the right temperature. A single failed refrigerator can lose $20,000 dollars worth of medication.
When is a good time for downtime? At URMC, they handle 90,000 Emergency Room vists per year, so the answer is never. When is the ER busiest? Monday morning. (not what I expected!)
URMC's EMR software (Epic) runs on clustered POWER7 servers, with DS8700 disk systems using Metro Mirror to secondary location. They also keep a third "shadow" POWER7 for read-only purposes, and a separate system that provides web-based read-only access. Finally, they have 90 stand-alone Personal Computers (PCs) that contain information for all the patients that have reservations this week, just in case all the other systems fail.
The exploding volume of data comes from medical imaging. For radiology (X-rays), each image is called a "study" takes 20-30 MB each, and they have 650,000 studies per year. This represents about 16TB storage per year, with 3 second response time access. These must be kept for 7 years since last view, or until the patient reaches the age of 18 years old, which ever is later.
But radiology is just one discipline. Healthcare has a whole bunch of "ologies". Another is "Pathology" which looks at cells between glass slides in a microscope. Each study consumes 10-20GB, and URMC does about 100,000 pathology studies per year, representing 150TB per year.
URMC has identified that they have 42 mission-critical applications. The data for these are stored on DS8000, XIV, Storwize V7000 and DS5000, all managed behind SAN Volume Controller.
During lunch, people were able to take a look at our solutions. Here are Dan Thompson and Brett Cooper striking a pose.
Hyper-Efficient Backup and Recovery
The afternoon was kicked off by Dr. Daniel Sabbah, IBM General Manager of Tivoli software. He started with some shocking statistics: 42 percent of small companies have experienced data loss, 32 percent have lost data forever. IBM has a solution that offers "Unified Recovery Management". This involves a combination of periodic backups, frequent snapshots, and remote mirroring.
IBM Tivoli Storage Manager (TSM) was introduced in 1993, and was the first backup software solution to support backup to disk storage pools. Today, TSM is now also part of Cloud Computing services, including IBM Information Protection Services. IBM announced today a new bundle called IBM Storwize Rapid Application Backup, which combines IBM Storwize V7000 midrange disk system, Tivoli FlashCopy Manager, implementation services, with a full three-year hardware and software warranty. This could be used, for example, to protect a Microsoft Exchange email system with 9000 mailboxes.
IBM also announced that its TS7600 ProtecTIER data deduplication solutions have been enhanced to support many-to-many bi-direction remote mirroring. Last year, University of Pittsburgh Medical Center (UPMC) reported that they were average 24x data deduplication factor in their environment using IBM ProtecTIER.
"You are out of your mind if you think you can live without tape!"
-- Dick Crosby, Director of System Administration, Estes
The new IBM TS1140 enterprise class tape drive process 2.3 TB per hour, and provides a density of 1.2 PB per square foot. The new 3599 tape media can hold 4TB of data uncompressed, which could hold up to 10TB at a 2.5x compression ratio.
The United States Golfers Association [USGA] uses IBM's backup cloud, which manages over 100PB of data from 750 locations across five continents.
Customer Testimonial - Graybar
Randy Miller, Manager of Technical System Administration at Graybar, provided the next client testimonial. Graybar is an employee-owned company focused on supply-chain management, serving as a distributor for electical, lighting, security, power and cooling equipment.
Their problem was that they had 240 different locations, and expecting local staff to handle tape backups was not working out well. They centralized their backups to their main data center. In the event that a system fails in one of their many remote locations, they can rebuild a new machine at their main data center across high-speed LAN, and then ship overnight to the remote location. The result, the remote location has a system up and running by 10:30am, faster than they would have had from local staff trying to figure out how to recover from tape. In effect, Graybar had implemented a "private cloud" for backup in the 1990s, long before the concept was "cool" or "popular".
In 2001, they had an 18TB SAP ERP application data repository. To back this up, they took it down for 1 minute per day, six days a week, and 15 minutes down on Sundays. The result was less than 99.8 percent availability. To fix this, they switched to XIV, and use Snapshots that are non-disruptive and do not impact application performance.
Over 85 percent of the servers at Graybar are virtualized.
Their next challenge is Disaster Recovery. Currently, they have two datacenters, one in St. Louis and the other in Kansas City. However, in the aftermath of Japan's earthquakes, they realize there is a nuclear power plan between their two locations, so a single incident could impact both data centers. They are working with IBM, their trusted advisors, to investigate a three-site solution.
This week, May 15-22, I am in Auckland, New Zealand teaching IBM Storage Top Gun sales class. Next week, I will be in Sydney, Australia.
