Well it's Tuesday, and ["election day"] here in the USA, and again IBM has more announcements.
IBM announced [IBM Tivoli Key Lifecycle Manager v1.0] (TKLM) to manage encryption keys. This provides a graphical interface to manage encryption keys, including retention criteria when sharing keys with other companies.
TKLM is supported on AIX, Solaris, Windows, Red Hat and SUSE Linux. IBM plans to offer TKLM forz/OS in 2009. TKLM can be used with Firefox or Internet Explorer web browser. This will include the Encryption Key Manager (EKM) that IBM offered initially to support encryption keys for the TS1120, TS1130, and LTO-4 drives.
While this is needed today for tape, IBM positions this software to also manage the encryption keys for "Full Drive Encryption" (FDE) disk drive modules (DDM) in IBM disk systems in 2009.
Continuing this week's theme on products that were part of last week'sIBM Information Infrastructure launch, today I'll cover the TS2900.
IBM System Storage TS2900 Tape Autoloader
This little baby is SWEET! At 1U high, it holds a single drive and up to 9 cartridges,up to a total of 14.4 TB at 2:1 compression. Thedrive can be a Half-Height (HH) LTO-3 or LTO-4 drive. (It is called an autoloader because there isonly a single drive. Automation with multiple drives are called libraries).
This can be rack-mounted, or sit on your desktop. There is an I/O station for insertingor removing individual cartridges, as well as a removable tape magazine to populate orremove the tapes in a more efficient manner.
Both LTO3 and LTO4 support a mix of regular and "Write Once, Read Many" (WORM) media tohelp comply with regulations demanding "Non-erasable, Non-rewriteable" storage. TheLTO4 can also support on-drive encryption, managed by the IBM Encryption Key Manager (EKM).

Well, it's Tuesday, and that means IBM announcements! Today is bigger, as there are a lot of Dynamic Infrastructure announcements throughout the company with a common theme, cloud computing and smart business systems that support the new way of doing things. Today, IBM announced its new "IBM Smart Archive" strategy that integrates software, storage, servers and services into solutions that help meet the challenges of today and tomorrow. IBM has been spending the past few years working across its various divisions and acquisitions to ensure that our clients have complete end-to-end solutions.
IBM is introducing new "Smart Business Systems" that can be used on-premises for private-cloud configurations, as well as by cloud-computing companies to offer IT as a service.
IBM [Information Archive] is the first to be unveiled, a disk-only or blended disk-and-tape Information Infrastructure solution that offers a "unified storage" approach with amazing flexibility for dealing with various archive requirements:
For those with applications using the IBM Tivoli Storage Manager (TSM) or IBM System Storage Archive Manager (SSAM) API of the IBM System Storage DR550 data retention solution, the Information Archive will provide a direct migration, supporting this API for existing applications.
For those with IBM N series using SnapLock or the File System Gateway of the DR550, the Information Archive will support various NAS protocols, deployed in stages, including NFS, CIFS, HTTP and FTP access, with Non-Erasable, Non-Rewriteable (NENR) enforcement that are compatible with current IBM N series SnapLock usage.
For those using NAS devices with PACS applications to store X-rays and other medical images, the Information Archive will provide similar NAS protocol interfaces. Information Archive will support both read-only data such as X-rays, as well as read/write data such as Electronic Medical Records.
Information Archive is not just for compliance data that was previously sent to WORM optical media. Instead, it can handle all kinds of data, rewriteable data, read-only data, and data that needs to be locked down for tamper protection. It can handle structured databases, emails, videos and unstructured files, as well as objects stored through the SSAM API.
The Information Archive has all the server, storage and software integrated together into a single machine type/model number. It is based on IBM's General Parallel File System (GPFS) to provide incredible scalability, the same clustered file system used by many of the top 500 supercomputers. Initially, Information Archive will support up to 304TB raw capacity of disk and Petabytes of tape. You can read the [Spec Sheet] for other technical details.
For those who prefer a more "customized" approach, similar to IBM Scale-Out File Services (SoFS), IBM has [Smart Business Storage Cloud]. IBM Global Services can customize a solution that is best for you, using many of the same technologies. In fact, IBM Global Services announced a variety of new cloud-computing services to help enterprises determine the best approach.
In a related announcement, IBM announced [LotusLive iNotes], which you can think of as a "business-ready" version of Google's GoogleApps, Gmail and GoogleCalendar. IBM is focused on security and reliability but leaves out the advertising and data mining that people have been forced to tolerate from consumer-oriented Web 2.0-based solutions. IBM's clients that are already familiar with on-premises version of Lotus Notes will have no trouble using LotusLive iNotes.
There was actually a lot more announced today, which I will try to get to in later posts.
In case you missed it, IBMunveiled a new digital video surveillance service yesterday. This "marks an important shift in the industry's approach to security, applying advanced analytics to video data and signaling the ability to converge physical and information technology (IT) security."
The IBM Smart Surveillance Solution is designed to provide the unique capability to carry out efficient data analysis of video sequences either in real time or from recordings. These recordings can be on disk or tape storage.
The problem with today's existing "analog" surveillance is that the analog cameras record onto traditional VHS tapes, and these are rotated through, re-written after a few hours or days. To review tapes often involves human intervention, and must be done before the VHS tapes are re-used. Many shoplifters, thieves, and other law-breakers take a chance that their actions will not be caught on tape, or that they will be long gone by the time the video is analyzed.
The IBM Smart Surveillance Solution can provide a number of advantages over traditional video solutions, including:
Real-time alerts that can help anticipate incidents by identifying suspicious behaviors.
Forensic capabilities are enhanced by utilizing unique indexing and attribute-based search of video events to classify objects into categories such as people and cars.
Situational awareness of the location, identity and activity of objects in a monitored space including license plate recognition and face capture.
With real-time analytics capabilities, the new DVS service can open up a wide array of new applications that go far beyond the traditional security aspects of surveillance systems. Early adopter industries in this rapidly evolving market include retail, public sector and financial services. The retail industry estimates nearly $50 billion is lost annually to fraud, theft and administrative errors.
Once in digital format, video surveillance can be sent further, processed quicker, and stored for longer periods of time, than traditional media makes practical today.
In last week's System Storage Portfolio Top Gun class in Dallas, some of the students were not familiarwith Really Simple Syndication (RSS). For the uninitiated, this can be intimidating.I thought a quick overview of what I've done might help:
Chose a "feed reader". I chose Bloglines but there are many others.
Use Technorati to search other blogs for keywords or phrases I am looking for.
When I find a blog that I like to continue tracking, I "add" it to my subscription list on bloglines. Just hit "add" and copy the URL of the blog you want to track. Bloglines will figure out the RSS keywords required.I track eight blogs at the momemnt, but some people with lots of time on their hands track 20 or more. It is easy to unsubscribe, so don't be afraid to try some out for a few days.
Since I was actually going to run a blog of my own, I read a few books on the topic. One I recommend is "Naked Conversations" by Robert Scoble and Shel Israel, both experienced bloggers.
Finally, I am not big on spell checking, but most places have the option to preview your post or comment before it actually gets posted, which is not a bad idea if you use any HTML tags.
For a quick taste of blogging, consider using Data Storage Blogger Feed Reader. This has a lot of blogs on the topic of storage, already added and categorized for your convenience, ready for your perusal.
I am sure there are many other ways to enjoy the Blogosphere, but this works for me.[Read More]
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.
With mixed emotions, Jon Peake announced he will retire from IBM next week. Jon is known as thefather of IBM Virtual Tape Server (VTS), the industry's first virtual tape system, announced in 1996and generally available in 1997.One of my 19 patents was for the VTS pre-migration capability, and as lead architect for DFSMS, I worked closely with Jon and his tape systems team to ensure its success.
From left to right:
Chris Telford, IBM Development manager for Enterprise Tape Integration
Jon Peake, IBM Distinguished Engineer and Master Inventor
Annette Estelle, Jon's global admin assistant
At his retirement celebration, Jon was awarded the coveted "Project Bulldog" jacket, which has an interesting history.
In response to IBM's 1996 VTS announcement, the top StorageTek (STK) tape sales teams and most of the dedicated tape technicians were invited to a global assembly at a fancy resort in Winter Park, CO (about 90 miles west of STK's Louisville headquarters) in early 1997. The gathering was named Project Bulldog, after Ron Korngiebel, STK's director of competitive marketing, who I am told had voice and facial resemblance to justify the project moniker. Ron had recruited Fred Moore, Steve Blenderman, and other prized engineers as speakers. I have seen both Fred and Steve speak at various conferences such as SHARE and GUIDE, and agree they are high quality speakers.
The goal was to have STK's brightest in Louisville go down in the trenches, work the field guys into a frenzy, defend STK Tape at any cost, and send IBM packing. At the end of the two day fest, many participants received the coveted Project Bulldog jacket.
Former STKers who now work at IBM can remember this meeting involved:
Bashing of the [IBM Seascape] architecture approach. The use of commodity servers and componentsto build storage systems continues today in the IBM System Storage DS8000, SAN Volume Controller,XIV, and TS7650 Deduplication solutions.
Explanations how and why IBM's VTS would never work, and how only STK virtual tape would make it in the market. Today, IBM is the leader in storage virtualization, both for disk and tape.
Mock interview videos with claims that IBM could never figure out how to attach IBM drives to the STK Silo. I was a big proponent of this, having visited customers who specifically asked for IBM to sell its better, faster IBM drives into their existing STK silos. At first, upper management was hesitant to do this, but the IBMengineers worked out what changes were needed, and today many STK tape automation libraries run with IBM tape drives.
While some analysts frowned on Sun's [2005 acquisition of StorageTek], IBM was delighted, given Sun's previous track record in storagecompany acquisitions. I joke that we are still picking up confetti in the hallways of IBM's Tucsonlab. I was in New York city when I heard Sun's announcement, and it didn't take long for STKemployees offering me their resumes.Since then, many STK engineers, technicians and sales team have left Sun, many coming over to IBM.Back then, there were many intelligent and talented people working for StorageTek, and IBM is gladto have hired them.
With the resurgence of interest in tape systems, from dealing with new legislation for long term retention of electronic data to a focus on energy efficiency, Jon leaves much like a champion retiring at the top of his game.
Jon, I am going to miss you! Enjoy your retirement!
Well, it's Tuesday, and you know what that means? IBM announcements!
Today we had several for the IBM System Storage product line. Here are some of them:
DS8000 gets thinner, leaner and faster
The 4.3 level of microcode for the IBM System Storage DS8000 series disk systems [announced enhancements] for both fixed block architecture (FBA) LUNs and count key data (CKD) volumes.
For FBA LUNs that attach to Linux, UNIX and Windows distributed systems, IBM announced DS8000 Thin Provisioning native support. Of course, many people already had this by putting IBM System Storage SAN Volume Controller (SVC) in front, but now DS8000 clients out there without SVC can also achieve benefits ofthin provisioning. This support also improves quick initialization a whopping 2.6 times faster.
For CKD volumes attached to z/OS on System z mainframes, IBM announced zHPF multitrack support for z/OS 1.9 and above. zHPF provide high performance FICON performance, and can now handle multitrack I/O transfers foreven better performance for zFS, HFS, PDSE, and extended striped data sets.
XIV gets better connected
A lot of XIV[announced enhancements] and preview announcements centered around better connectivity. Here's a run down:
Better host attachment connectivity by beefing up the interface modules that hold the FCP and iSCSI interface cards. XIV disk arrays have 3 to 6 of these in different configurations, and since they manage both their own disks,as well as receive host I/O requests for other disks, are basically doing double-duty.These interface modules can now be ordered as [Dual-CPU] modules.
Better infrastructure management by connecting XIV with the industry standard SMI-S interface to IBM Tivoli Storage Productivity Center. Now, XIV can be part of the single pane of glass console that manages all of your other disk arrays, tape libraries and SAN fabrics.
Better copy services for backups by connecting XIV with IBM Tivoli Storage Manager Advanced Copy Services. TSM for Advanced Copy Services is application aware and can coordinate XIV Snapshots similar to its current support for SVC and DS8000 FlashCopy capabilities.
Better connectivity to security systems by supporting LDAP credentials. Before, you had individual userid and passwords for each XIV, and these were probably different than all the other userid/password combinations you have for every other box on your data center floor. IBM is working on getting all products to support theLightweight Directory Access Protocol, or [LDAP] so that we can reach the nirvana of "single sign-on",one userid/password per administrator for all IT devices in the company.
Better support with flexible warranty periods and non-disruptive code load options.
Better remote copy support by connecting to sites far, far away. IBM previewed that it will provideasynchronous disk mirroring from one XIV to another XIV natively. Before this, XIV's synchronous mirroring was limited to 300km distances. Many of our clients do long distance global mirroring of their XIV today behind an SVC, but again, for those out there that don't yet have an SVC, this can be a reasonable alternative.
TS7650 ProtecTIER data deduplication appliance now offers "no dedupe" option
In what some might consider a surprising move, IBM announced a "no dedupe" licensing option on their premiere deduplication solution, which somewhat reminds me of IBM's NOCOPY option on DS8000 FlashCopy. At first I thought "Are you kidding me?!?!" However, this new license option allows the TS7650 appliance to compete with other virtual tape libraries (VTL) that do not offer deduplication capability on an even playing field. It also allows TS7650 to be used for data that doesn'tdedupe very well, such as seismic recordings, satellite images, or what have you. There are also clients who do not yet feel comfortable to dedupe their financial records for compliance reasons.This option now allows IBM to withdraw from marketing the TS7530 non-dedupe library. Having one technology thatdoes both dedupe and no-dedupe is better than offering two separate libraries based on different technologies.
The ProtecTIER series also announced [IP remote distance replication]. This can be used to replicate virtualtape cartridges in one ProtecTIER over to another ProtecTIER at a remote location. You can decide to replicateall or just a subset of your virtual tapes, and this feature can be used to migrate, merge or split ProtecTIERconfigurations as your needs grow. Before this support, our TS7650G clients replicated the disk repositoryusing native disk array replication technology, such as Global Mirror on the DS8000, but that meant that all data was replicated over to the secondary site. Now, with this new IP replication feature, you can be selective, and replicate only those virtual tapes that are mission critical.
The appliance now supports up to 36TB of disk capacity, and the new "IBM i" operating system on System i servers,formerly known as i5/OS.
GPFS does Windows
IBM's General Parallel File System (GPFS) has the lion's marketshare of file systems used in the [Top 500 Supercomputers]. For a while, it was limited to just Linux and AIX operating system support, but version 3.3 [extends this to Windows 2008 on 64-bit architectures]. GPFS isthe file system used in IBM's Scale-Out File Services, the underlying technology of IBM's Cloud Computing and Storage offerings.
Well, it's Tuesday again, and that means more announcements from IBM!
In conjunction with IBM's new [System z10 Business Class (BC)] mainframe designed for Small and Medium-sized Businesses (SMB), IBM also announced related storage productenhancements.
Yes, it's alive! Contrary to the FUD you might have read from our competitors, IBM continues to sell thousands and thousands of IBM System Storage DS6800 disk systems, and now enhances them with the optionfor 450GB 15K RPM drives. What is nice about these 450GB drives is that they are as fast or faster* than 300GBdrives, so the typical trade-off between performance and capacity do not apply.
(* I compared Seagate 15.6K (450GB) with 15.5K (300GB) models.
Avg Seek time (Read)
Avg Seek time (Write)
Full Seek time (Read)
Full Seek time (Write)
This may or may not result in application performance improvements, depending on workload pattern. Your mileage may vary.)
Our clients report back that these are incredibly stable systems that they don't have toworry about. This enhancement applies to both the [511/EX1 models] and [522/EX2 models].
Understanding that clients want complete solutions from single vendors, IBM offers synergy between System z and the IBM System Storage DS8000 disk systems. The latest R4.1 microcode upgrade offers two key features onthe various models [2107,
zHPF - High Performance FICON for System z. IBM was able to increase the throughput on 4 Gbps links. For OLTP workloads randomly accessing 4KB blocks, IBM internal tests showed zHPF doubled performance from 13,000 IOPSto 26,000 IOPS per channel. For sequential workloads, such as batch processing, zHPF increased performance 50 percent, from 350 MB/sec to 525 MB/sec.
In February, IBM previewed[IncrementalResync] for z/OS Metro Global Mirror. However, some concepts are better explained with pictures.
One way to set up a 3-site disaster recovery protection is to have your production synchronously mirrored to a second site nearby, and at the same time asynchronously mirrored to a remote location. On the System z, you can have site "A" using synchronous IBM System Storage Metro Mirror over to nearby site "B", and also have site "A" sending data over to site "C" asynchronously using z/OS Global Mirror. This is called "z/OS Metro Global Mirror".
In the past, if the disk system in site A failed, you would switch over to site B, which would have to resend send all the data again to site C to be resynchronized. This is because site B was not tracking what the System Data Mover (SDM) reader had or had not yet processed.
With DS8000 4.1, the "incremental resync" function that, along with using IBM HyperSwap, requires site B to only send and resync the data that was in-flight when the outage occurred. When you compare the difference in sending this limited amount of in-flight data with the traditional complete volume of data, you can see how "Incremental Resync" can resynchronize the data 95% faster, and also greatly decrease your bandwidth requirements. This reduces the risk in case a subsequent outage occurs.
Introduced originally in 1997 as the IBM Virtual Tape Server (VTS), the [IBMSystem Storage TS7700] series supports Grid capabilityto replicate tape image data across locations. Here's a quick recap of today's announcement:
Existing TS7740 can be upgraded up to 9TB of disk cache. New models can have up to 13TB of disk cache.
A new "tape-less" TS7720 that has up to 70TB of disk cache.
Integrate Library Management support. I discussed[IntegratedRemovable Media Manager (IRMM)] before, and this is basically IRMM inside. For those with TS3500 tape libraries,this support eliminates the need for a separate IBM 3953 L05 Library Manager.
TS1130 back-end tape drive support. These are the fastest 1TB drives in the industry, with support of built-in encryption, and now can be used asthe physical tape back-end for the virtual tape TS7740 repository.
While our competitors might be boarding up their windows in preparation for the economic downturn in the USAeconomy, IBM remains generating solid results. San Jose Mercury News has an article that discusses this titled[IBM's 3Q profit strong on global sales].There has never been a better time to buy from, or invest in, IBM!
For those of us in the northern hemisphere, yesterday was this year's Winter Solstice, representingthe shortest amount of daylight between sunrise and sunset. So today, I thought I would blog on my thoughtsof managing scarcity.
Earlier in my career, I had the pleasure to serve as "administrative assistant" to Nora Denzel for the week at a storage conference. My job was to make her look good at the conference, which if you know Nora, doesn't take much. Later, she left IBM to work at HP, and I gotto hear her speak at a conference, and the one thing that I remember most was her statement that thewhole point of "management" was to manage scarcity, as in not enough money in the budget,not enough people to implement change, or not enough resources to accomplish a task.(Nora, I have no idea where you are today, so if you are reading this, send me a note).
Of course, the flip-side to this is that resources that are in abundance are generallytaken for granted. Priorities are focused on what is most scarce. Let's examine some of theresources involved in an IT storage environment:
Capacity - while everyone complains that they are "running out of space", the truth is that most external disk attached to Linux, UNIX, or Windows systems contain only 20-40% data. Many years ago, I visitedan insurance company to talk about a new product called IBM Tivoli Storage Manager. This company had 7TB of disk on their mainframe,and another 7TB of disk scattered on various UNIX and Windows machines. In the room were TWO storage admins for
the mainframe, and 45 storage admins for the distributed systems. My first question was "why so many people forthe mainframe, certainly one of you could manage all of it yourself, perhaps on Wednesday afternoons?" Their response was that they acted as eachother's backup, in case one goes on vacation for two weeks. My follow-up question to the rest of the audience was:"When was the last time you took two weeks vacation?" Mainframes fill their disk and tape storage comfortablyat over 80-90% full of data, primarily because they have a more mature, robust set of management software, likeDFSMS.
Labor - by this I mean skilled labor able to manage storage for a corporation. Some companies I have visitedkeep their new-hires off production systems for the first two years, working only on test or development systemsonly until then. Of course, labor is more expensive in some countries than others. Last year, I was doing a whiteboard session on-site for a client in China, and the last dry-erase pen ran out of ink. I asked for another pen, and they instead sent someone to go re-fill it. I asked wouldn't it be cheaper just to buy another pen, and they said "No, labor is cheap, but ink is expensive." Despite this, China does complain that there is a shortage of askilled IT labor force, so if you are looking for a job, start learning Mandarin.
Power and Cooling - Most data centers are located on raised floors, with large trunks of electrical power and hugeair conditioning systems to deal with all the heat generated from each machine. I have visited the data centers ofclients that are forced now to make decisions on storage based on power and cooling consumption, because the coststo upgrade their aging buildings are too high. Leading the charge is IBM, with technology advancements in chips, cards, and complete systems that use less power, and generate less heat. While energy is still fairly cheap in the grand scheme of things, fears ofGlobal Warmingand declining oil supplies, the costs ofpower and cooling have gotten some news lately. In 1956, Hubbert predicted US would reach peak oil supplies by1965-1970 (it happened in 1971), and this year Simmonsestimated that world-wide oil production began its decline already in 2005. Smart companies like Google have movedtheir server farms to places like Oregon in the Pacific Northwest for cheaper hydroelectric power.
Bandwidth - Last year IBM introduced 4Gbps Fibre Channel and FICON SAN networking gear, along with the servers and storage needed to complete the solution. 4Gbps equates to about 400 MB/sec in data throughput. By comparison, iSCSI is typically run on 1Gbps Ethernet, but has so much overheads that you only get abour 80 MB/sec. Next year, we may see both 8 Gbps SAN, and 10 GbE iSCSI, to provide 800 MB/sec throughputs. My experience is that the SAN is not the bottleneck, instead people run out of bandwidth at the server or storage end first. They may not have a million dollars to buy the fastest IBM System p5 servers, or may not have enough host adapters at the storage system end.
Floorspace - I end with floorspace because it reminds me that many "shortages" are temporary or artificially created. Floorspace is only in short supply because you don't want to knock down a wall, or build a new building, to handle your additional storage requirements.In 1997, Tihamer Toth-Fejel wrote an article for the National Space Society newsletter that estimated that ...Everybody on Earth could live comfortably in the USA on only 15% of our land area, with a population density between that of Chicago and San Francisco. Using agricultural yields attained widely now, the rest of the U.S. would be sufficient to grow enough food for everyone. The rest of the planet, 93.7% of it, would be completely empty.Of course, back in 1997 the world population was only 5.9 billion, and this year it is over 6.5 billion.
This last point brings me back to the concept of food, and I am not talking about doughnuts in the conference room, or pizza while making year-end storage upgrades. I'm talking aboutthe food you work so hard to provide for yourself and your family. The folks at Oxfam came up with a simpleanalogy. If 20 people sit down at your table, representing the world’s population:
3 would be served a gourmet, multi-course meal, while sitting at decorated table and a cushioned chair.
5 would eat rice and beans with a fork and sit on a simple cushion
12 would wait in line to receive a small portion of rice that they would eat with their hands while sitting on the floor.
So for those of you planning a special meal next Monday, be thankful you are one of the lucky three, and hopefulthat IBM will continue to lead the IT industry to help out the other seventeen.
Well, it's Tuesday again, and that means more IBM announcements!
Storage Area Network (SAN)
IBM and Cisco announced [three new blades] for the Cisco MDS 9500 seriesdirectors: 24-port 8 Gbps, 48-port 8 Gbps, and 4/44 blended. The 4/44blended has 4 of the faster 8 Gbps ports, and 44 of the 4 Gpbs ports,so that you can auto-negotiate down to 1 Gbps for your older gear, andstill take advantage of the faster 8 Gbps speeds during the transition.
On the Brocade side, IBM announced the newIBM System Storage Data Center Fabric Manager [DCFM] V10 software. This replaces the products formerly known as BrocadeFabric Manager and McData Enterprise Fabric Connection Manager (EFCM).This software can support up to 24 distinct fabrics, up to 9000 ports,including a mix of FCP, FICON, FCIP and iSCSI protocols.
(On a related note, I heard that Microsoft is planning to rename "Windows Vista" to "Windows 7" next year! Like we say here in Tucson,if it ends in "-ista" it is going to fail in the marketplace! Perhaps EMC should rename their storage virtualization product to "In-7"?).
IBM System Storage DR550
IBM announced today that it now supports [RAID 6 onthe DR550] compliance and retention storage system.
There are a few RAID-5 based EMC Centera customers out there who have notyet switched over to the IBM DR550, and now this might be just the littlenudge they need. For long-term retention of regulatory compliance data,RAID-5 doesn't cut it, you need an advanced RAID scheme, such as RAID-6, RAID-DP or RAID-X.
The DR550 provides non-erasable, non-rewriteable (NENR) storage supportto keep retention-managed data on disk and tape media. It supports 1 TBSATA disk drives and 1TB tape cartridges to provide high capacity at lowcost and "green" low energy consumption.
IBM System Storage N series
Several of our disk systems got improved and enhanced. Let's start withthe IBM System Storage N series[hardware and software] enhancements. IBM now offers high-speed 450GB 15K RPM drives. These are Fibre Channel (FC) drives for the EXN4000 expansion drawers, and Serial Attached SCSI (SAS) drives for the entry-levelN3300 and N3600 models.
The "gateway" models now support a variety of functions that were formerlyonly available on the appliance models. This includes Advanced Single Instance Storage (A-SIS), Disk Sanitization, and FlexScale.
A-SIS is IBM's "other" deduplication function, and I talked about this in my post [A-SIS Storage Savings Estimator Tool]. Disk Sanitization will physicallywrite ones and zeros over existing data to eliminate it, what IBM sometimes calls "Data Shredding".
The last feature, FlexScale, might be new for many. It is software toenable to use of the "Performance Accelerator Module" (PAM). The PAM isa PCI-Express card with 16GB on-board RAM that acts as a secondary cachebehind main memory of the N series controller. Depending on the model,you can have one to five of these cards fit into the controller itself,boosting random read performance, metadata access, and write block destage.
IBM System Storage DS5000
IBM's latest entry into the DS family has been hugely successful.In addition to Linux, Windows and AIX, the DS5000 now supports [Novell Netware and Sun Solaris] operating systems.
For infrastructure management, IBM has enhanced the Remote Support Manager [RSM]that supports DS3000 and DS4000 has been extended to support DS5000 as well. This software can monitor up to 50 disk systems, will e-mail alerts to IBM when something goes wrong, and allow IBM to dial in via modem to get more diagnostic information to improve service to the client. Also, the IBM System Storage Productivity Center [SSPC]which now supports the DS8000 and SAN Volume Controller (SVC) has been extended to also support the DS5000.
IBM XIV Storage System
In addition to 1-year and 3-year maintenance agreements, IBM now offers[2-year, 4-year and 5-year] software maintenance agreements.
RFID labels for IBM tape media
IBM 3589 (20-pack of LTO cartridges) and IBM 3599 (20-pack of 3592 cartridges for TS1100 series)now offer [RFID labels]. These labels match the volume serial (VOLSER) with a 216-bit unique identifier and 256 bits of user-defined content. This can help with tape inventory,and to prevent people from walking out of the building with a tape cartridge stuffed in their jacket.
32GB memory stick
While not technically part of the IBM System Storage matrix of offerings, Lenovo announced their new[Essential Memory Key] which holds 32GB of memory and workswith both USB 1.1 and USB 2.0 protocols.
I wish I could say this is it for the IBM announcements for October, given that this is the last Tuesday of the month, but there are three days left, so there might be just a few more!
This post will focus on Information Compliance, the fourth and final part of the four-part series this week.I have received a few queries on my choice of sequence for this series: Availability, Security, Retention andCompliance.
Why not have them in alphabetical order? IBM avoids alphabetizing in one language, because thenit may not be alphabetized when translated to other languages.
Why not have them in a sequence that spells outan easy to remember mnemonic, like "CARS"? Again, when translated to other languages, those mnemonics no longerwork.
Instead, I worked with our marketing team for a more appropriate sequence, based on psychology and the cognitive bias of [primacy and recency effects].
Here's another short 2-minute video, on Information Compliance
Full disclosure: I am not a lawyer. The following will delveinto areas related to government and industry regulations. Consultyour risk officer or legal counsel to make sure any IT solution is appropriatefor your country, your industry, or your specific situation.
IBM estimates there are over 20,000 regulations worldwide related to information storage and transmission.
For information availability, some industry regulations mandate a secondary copy a minimum distance away toprotect against regional disasters like hurricanes or tsunamis.IBM offers Metro Mirror (up to 300km) and Global Mirror (unlimited distance) disk mirroring to support theserequirements.
For information security, some regulations relate to privacy and prevention of unauthorized access. Twoprominent ones in the United States are:
Health Insurance Portability and Accountability Act (HIPAA) of 1996
HIPAA regulates health care providers, health plans, and health care clearinghouses in how they handle the privacy of patient's medical records. These regulations apply whether the information is on film, paper, or storedelectronically. Obviously, electronic medical records are easier to keep private. Here is an excerpt froman article from [WebMD]:
"There are very good ways to protect data electronically. Although it sounds scary, it makes data more protected than current paper records. For example, think about someone looking at your medical chart in the hospital. It has a record of all that is happening -- lab results, doctor consultations, nursing notes, orders, prescriptions, etc. Anybody who opens it for whatever reason can see all of this information. But if the chart is an electronic record, it's easy to limit access to any of that. So a physical therapist writing physical therapy notes can only see information related to physical therapy. There is an opportunity with electronic records to limit information to those who really need to see it. It could in many ways allow more privacy than current paper records."
GLBA regulates the handling of sensitive customer information by banks, securities firms, insurance companies, and other financial service providers. Financial companies use tape encryption to comply with GLBA when sending tapes from one firm to another. IBM was the first to deliver tape drive encryption withthe TS1120, and then later with LTO-4 and TS1130 tape drives.
For information retention, there are a lot of regulations that deal with how information is stored, in some casesimmutable to protect against unethical tampering, and when it can be discarded. Two prominent regulations inthe United States are:
U.S. Securities and Exchange Commission (SEC) 17a-4 of 1997
In the past, the IT industryused the acronym "WORM" which stands for the "Write Once, Read Many" nature of certain media, like CDs, DVDs,optical and tape cartridges. Unfortunately, WORM does not apply to disk-based solutions, so IBM adopted the languagefrom SEC 17a-4 that calls for storage that is "Non-Erasable, Non-Rewriteable" or NENR. This new umbrella term applies to disk-based solutions, as well as tape and optical WORM media.
SEC 17a-4 indicates that broker/dealers and exchange members must preserve all electronic communications relating to the business of their firmm a specific period of time. During this time, the information must not be erased or re-written.
Sarbanes-Oxley (SOX) Act of 2002
SOX was born in the wake of [Enron and other corporate scandals]. It protects the way that financial information is stored, maintained and presented to investors, as well as disciplines those who break its rules. It applies onlyto public companies, i.e. those that offer their securities (stock shares, bonds, liabilities) to be sold to the publicthrough a listing on a U.S. exchange, such as NASDAQ or NYSE.
SOX focuses on preventing CEOs and other executives from tampering the financial records.To meet compliance, companies are turning to the [IBM System Storage DR550] which providesNon-erasable, Non-rewriteable (NENR) storage for financial records. Unlike competitive products like EMC Centera thatfunction mostly as space-heaters on the data center floor once they filled up, the DR550 can be configured as a blended disk-and-tape storage system, so that the most recent, and most likely to be accessed data, remains on disk, but the older, least likely to be accessed data, is moved automatically to less expensive, more environment-friendly "green" tape media.
Did SOX hurt the United States' competitiveness? Critics feared that these new regulations would discourage newcompanies from going public. Earnst & Young found these fears did not come true, and published a study [U.S. Record IPO Activity from 2006 Continues in 2007]. In fact, the improved confidence that SOX has given investors has given rise to similarlegislation in other parts of the world: Euro-Sox for the European Union Investor Protection Act, and J-SOX Financial Instruments and Exchange Law for Japan.
For those who only read the first and last paragraphs of each post, here is my recap:Information Compliance is ensuring that information is protected against regional disasters, unauthorizedaccess, and unethical tampering, as required to meet industry and government regulations. Such regulationsoften apply if the information is stored on traditional paper or film media, but can often be handled more cost-effectively when stored electronically. Appropriate IT governance can help maintain investor confidence.
In Monday's post, [IBM Information Infrastructure launches today], I explained how this strategic initiative fit into IBM's New EnterpriseData Center vision. The launch was presented at the IBM Storage and Storage Networking Symposium to over 400 attendeesin Montpelier, France, with corresponding standing-room-only crowds in New York and Tokyo.
This post will focus on Information Retention, the third of the four-part series this week.
Here's another short 2-minute video, on Information Retention
Let's start with some interesting statistics.Fellow blogger Robin Harris on his StorageMojo blog has an interesting post:[Our changing file workloads],which discusses the findings of study titled"Measurement and Analysis of Large-Scale Network File System Workloads"[14-page PDF]. This paper was a collaborationbetween researchers from University of California Santa Cruz and our friends at NetApp.Here's an excerpt from the study:
Compared to Previous Studies:
Both of our workloads are more write-oriented. Read to write byte ratios have significantly decreased.
Read-write access patterns have increased 30-fold relative to read-only and write-only access patterns.
Most bytes are transferred in longer sequential runs. These runs are an order of magnitude larger.
Most bytes transferred are from larger files. File sizes are up to an order of magnitude larger.
Files live an order of magnitude longer. Fewer than 50 percent are deleted within a day of creation.
Files are rarely re-opened. Over 66 percent are re-opened once and 95% fewer than five times.
Files re-opens are temporally related. Over 60 percent of re-opens occur within a minute of the first.
A small fraction of clients account for a large fraction of file activity. Fewer than 1 percent of clients account for50 percent of file requests.
Files are infrequently shared by more than one client. Over 76 percent of files are never opened by more than one client.
File sharing is rarely concurrent and sharing is usually read-only. Only 5 percent of files opened by multiple clients are concurrent and 90 percent of sharing is read-only.
Most file types do not have a common access pattern.
Why are files being kept ten times longer than before? Because the information still has value:
Provide historical context
Gain insight to specific situations, market segment demographics, or trends in the greater marketplace
Help innovate new ideas for products and services
Make better, smarter decisions
National Public Radio (NPR) had an interesting piece the other day. By analyzing old photos, a researcher for Cold War Analysis was able to identify an interesting [pattern for Russian presidents]. (Be sure to listen to the 3-minute audio to hear a hilarious song about the results!)
Which brings me to my own collection of "old photos". I bought my first digital camera in the year 2000,and have taken over 15,000 pictures since then. Before that,I used 35mm film camera, getting the negatives developed and prints made. Some of these date back to my years in High School and College. I have a mix of sizes, from 3x5, 4x6 and 5x7 inches,and sometimes I got double prints.Only a small portion are organized intoscrapbooks. The rest are in envelopes, prints and negatives, in boxes taking up half of my linen closet in my house.Following the success of the [Library of Congress using flickr],I decided the best way to organize these was to have them digitized first. There are several ways to do this.
This method is just too time consuming. Lift the lid place 1 or a few prints face down on the glass, close the lid,press the button, and then repeat. I estimate 70 percent of my photos are in [landscape orientation], and 30 percent in [portrait mode]. I can either spend extra time toorient each photo correctly on the glass, or rotate the digital image later.
I was pleased to learn that my Fujitsu ScanSnap S510 sheet-feed scanner can take in a short stack (dozen or so) photos, and generate JPEG format files for each. I can select 150, 300 or 600dpi, and five levels of JPEG compression.All the photos feed in portrait mode, which I can then rotate later on the computer once digitized.A command line tool called [ImageMagick] can help automate the rotations.While I highly recommend the ScanSnap scanner, this is still a time-consuming process for thousands of photos.
"The best way to save your valuable photos may be by eliminating the paper altogether. Consider making digital images of all your photos."
Here's how it works:You ship your prints (or slides, or negatives) totheir facility in Irvine, California. They have a huge machine that scans them all at 300dpi, no compression, andthey send back your photos and a DVD containing digitized versions in JPEG format, all for only 50 US dollars plusshipping and handling, per thousand photos. I don't think I could even hire someone locally to run my scanner for that!
The deal got better when I contacted them. For people like me with accounts on Facebook, flickr, MySpace or Blogger,they will [scan your first 1000 photos for free] (plus shipping and handling). I selected a thousand 4x6" photos from my vast collection, organized them into eight stacks with rubber bands,and sent them off in a shoe box. The photos get scanned in landscape mode, so I had spent about four hours in preparing what I sent them, making sure they were all face up, with the top of the picture oriented either to the top or left edge.For the envelopes that had double prints, I "deduplicated" them so that only one set got scanned.
The box weighed seven pounds, and cost about 10 US dollars to send from Tucson to Irvinevia UPS on Tuesday. They came back the following Monday, all my photos plus the DVD, for 20 US dollars shipping and handling. Each digital image is about 1.5MB in size, roughly 1800x1200 pixels in size, so easily fit on a single DVD. The quality is the sameas if I scanned them at 300dpi on my own scanner, and comparable to a 2-megapixel camera on most cell phones.Certainly not the high-res photos I take with my Canon PowerShot, but suitable enough for email or Web sites. So, for about 30 US dollars, I got my first batch of 1000 photos scanned.
ScanMyPhotos.com offers a variety of extra priced options, like rotating each file to the correct landscape or portrait orientation, color correction, exact sequence order, hosting them on their Web site online for 30 days to share with friends and family, and extra copies of the DVD.All of these represent a trade-off between having them do it for me for an additional fee, or me spending time doing it myself--either before in the preparation, or afterwards managing the digital files--so I can appreciate that.
Perhaps the weirdest option was to have your original box returned for an extra $9.95? If you don't have a hugecollection of empty shoe boxes in your garage, you can buy a similarly sized cardboard box for only $3.49 at the local office supply store, so I don't understand this one. The box they return all your photos in can easily be used for the next batch.
I opted not to get any of these extras. The one option I think they should add would be to have them just discardthe prints, and send back only the DVD itself. Or better yet, discard the prints, and email me an ISO file of the DVD that I can burn myself on my own computer.Why pay extra shipping to send back to me the entire box of prints, just so that I can dump the prints in the trash myself? I will keep the negatives, in case I ever need to re-print with high resolution.
Overall, I am thoroughlydelighted with the service, and will now pursue sending the rest of my photos in for processing, and reclaim my linen closet for more important things. Now that I know that a thousand 4x6 prints weighs 7 pounds, I can now estimate how many photos I have left to do, and decide on which discount bulk option to choose from.
With my photos digitized, I will be able to do all the things that IBM talks about with Information Retention:
Place them on an appropriate storage tier. I can keep them on disk, tape or optical media.
Easily move them from one storage tier to another. Copying digital files in bulk is straightforward, and as new techhologies develop, I can refresh the bits onto new media, to avoid the "obsolescence of CDs and DVDs" as discussed in this article in[PC World].
Share them with friends and family, either through email, on my Tivo (yes, my Tivo is networked to my Mac and PC and has the option to do this!), or upload themto a photo-oriented service like [Kodak Gallery or flickr].
Keep multiple copies in separate locations. I could easily burn another copy of the DVD myself and store in my safe deposit box or my desk at work.With all of the regional disasters like hurricanes, an alternative might be to backup all your files, including your digitized photos, with an online backup service like [IBM Information Protection Services] from last year's acquisition of Arsenal Digital.
If the prospect of preserving my high school and college memories for the next few decades seems extreme,consider the [Long Now Foundation] is focused on retaining information for centuries.They areeven suggesting that we start representing years with five digits, e.g., 02008, to handle the deca-millennium bug which will come into effect 8,000 years from now. IBM researchers are also working on [long-term preservation technologies and open standards] to help in this area.
For those who only read the first and last paragraphs of each post, here is my recap:Information Retention is about managing [information throughout its lifecycle], using policy-based automation to help with the placement, movement and expiration. An "active archive" of information serves to helpgain insight, innovate, and make better decisions. Disk, tape, and blended disk-and-tape solutions can all play a part in a tiered information infrastructure for long-term retention of information.
In Monday's post, [IBM Information Infrastructure launches today], I explained how this strategic initiative fit into IBM's New EnterpriseData Center vision. For you podcast fans, IBM Vice Presidents Bob Cancilla (Disk Systems), Craig Smelser (Storage and Security Software), and Mike Riegel (Information Protection Services), highlight some of the new products and offerings in this 12-minute recording:
This post will focus on Information Security, the second of the four-part series this week.
Here's another short 2-minute video, on Information Security
Security protects information against both internal and external threats.
For internal threats, most focus on whether person A has a "need-to-know" about information B. Most of the time, thisis fairly straightforward. However, sometimes production data is copied to support test and development efforts. Here is the typical scenario: the storage admin copies production data that contains sensitive or personal informationto a new copy and authorizes software engineers or testers full read/write access to this data.In some cases, the engineers or testers may be employees, other times they might be hired contractors from an outside firm.In any case, they may not be authorized to read this sensitive information. To solve this IBM announced the[IBM Optim Data Privacy Solution] for a variety of environments, including Siebel and SAP enterprise resource planning (ERP)applications.
I found this solution quite clever. The challenge is that production data is interrelated and typically liveinside [relational databases].For example, one record in one database might have a name and serial number, and then that serial number is used to reference a corresponding record in another database. The IBM Optim Data Privacy Solution applies a range of"masks" to transform complex data elements such as credit card numbers, email addresses and national identifiers, while retaining their contextual meaning. The masked results are fictitious, but consistent and realistic, creating a “safe sandbox” for application testing. This method can mask data from multiple interrelated applications to create a “production-like” test environment that accurately reflects end-to-end business processes.The testers get data they can use to validate their changes, and the storage admins can rest assured theyhave not exposed anyone's sensitive information.
Beyond just who has the "need-to-know", we might also be concerned with who is "qualified-to-act".Most systems today have both authentication and authorization support. Authentication determines that youare who you say you are, through the knowledge of unique userid/passwords combinations, or other credentials. Fingerprint, eye retinal scans or other biometrics look great in spy movies, but they are not yetwidely used. Instead, storage admins have to worry about dozens of different passwords on differentsystems. One of the many preview announcements made by Andy Monshaw on Monday's launch was that IBM isgoing to integrate the features of [Tivoli Access Manager for Enterprise Single Sign-On] into IBM's Productivity Center software, and be renamed "IBM Tivoli Storage Productivity Center".You enter one userid/password, and you will not have to enter the individual userid/password of all the managedstorage devices.
Once a storage admin is authenticated,they may or may not be authorized to read or act on certain information.Productivity Center offers role-based authorization, so that people can be identifiedby their roles (tape operator, storage administrator, DBA) and that would then determine what they areauthorized to see, read, or act upon.
For external threats, you need to protect data both in-flight and at-rest. In-flight deals with data thattravels over a wire, or wirelessly through the air, from source to destination. When companies have multiplebuildings, the transmissions can be encrypted at the source, and decrypted on arrival.The bigger threat is data at-rest. Hackers and cyber-thieves looking to download specific content, like personal identifiable information, financial information, and other sensitive data.
IBM was the first to deliver an encrypting tape drive, the TS1120. The encryption process is handled right at the driveitself, eliminating the burden of encryption from the host processing cycles, and eliminating the need forspecialized hardware sitting between server and storage system. Since then, we have delivered encryption onthe LTO-4 and TS1130 drives as well.
When disk drives break or are decommissioned, the data on them may still be accessible. Customers have a tough decision to make when a disk drive module (DDM) stops working:
Send it back to the vendor or manufacturer to have it replaced, repaired or investigated, exposing potentialsensitive information.
Keep the broken drive, forfeit any refund or free replacement, and then physically destroy the drive. Thereare dozens of videos on [YouTube.com] on different ways to do this!
The launch previewed the [IBM partnership with LSI and Seagate] to deliver encryption technology for disk drives, known as "Full Drive Encryption" or FDE.Having all data encrypted on all drives, without impacting performance, eliminates having to decide which data gets encryptedand which doesn't. With data safely encrypted, companies can now send in their broken drives for problemdetermination and replacement.Anytime you can apply a consistent solution across everything, without human intervention anddecision making, the less impact it will have. This was the driving motivation in both disk and tape driveencryption.
(Early in my IBM career, some lawyers decided we need to add a standard 'paragraph' to our copyright text in the upper comment section of our software modules, and so we had a team meeting on this. The lawyer that presented to us that perhaps only20 to 35 percent of the modules needed to be updated with this paragraph, and taught us what to look for to decidewhether or not the module needed to be changed. Myteam argued how tedious this was going to be, that this will take time to open up each module, evaluate it, and make the decision. With thousands of modules involved the process could take weeks. The fact that this was going to take us weeks did not seem to concern our lawyer one bit, it was just thecost of doing business.Finally, I asked if it would be legal to just add the standard paragraph to ALL the modules without any analysis whatsoever. The lawyer was stunned. There was no harm adding this paragraph to all the modules, he said, but that would be 3-5x more work and why would I even suggest that. Our team laughed, recognizing immediately that it was the fastest way to get it done. One quick program updated all modules that afternoon.)
To manage these keys, IBM previewed the Tivoli Key Lifecycle Manager (TKLM).This software helps automate the management of encryption keys throughout their lifecycle to help ensure that encrypted data on storage devices cannot be compromised if lost or stolen. It will apply to both disk and tapeencryption, so that one system will manage all of the encryption keys in your data center.
For those who only read the first and last paragraphs of each post, here is my recap:Information Security is intended as an end-to-end capability to protect against both internal and external threats, restricting access only to those who have a "need-to-know" or are "qualified-to-act". Security approacheslike "single sign-on" and encryption that applies to all tapes and all disks in the data center greatly simplify the deployment.

How IT storage impacts society and industry
You can choose between hardcover (with dust jacket) or paperback versions:
This is not the first time I've been published. I have authored articles for storage industry magazines, written large sections of IBM publications and manuals, submitted presentations and whitepapers to conference proceedings, and even had a short story published with illustrations by the famous cartoon writer[Ted Rall].
But I can say this is my first blook, and as far as I can tell, the first blook from IBM's many bloggers on DeveloperWorks, and the first blook about the IT storage industry.I got the idea when I saw [Lulu Publishing] run a "blook" contest. The Lulu Blooker Prize is the world's first literary prize devoted to "blooks"--books based on blogs or other websites, including webcomics. The [Lulu Blooker Blog] lists past year winners. Lulu is one of the new innovative "print-on-demand" publishers. Rather than printing hundredsor thousands of books in advance, as other publishers require, Lulu doesn't print them until you order them.
I considered cute titles like A Year of Living Dangerously, orAn Engineer in Marketing La-La land, or Around the World in 165 Posts, but settled on a title that matched closely the name of the blog.
In addition to my blog posts, I provide additional insights and behind-the-scenes commentary. If you go to the Luluwebsite above, you can preview an entire chapter in its entirety before purchase. I have added a hefty 56-page Glossary of Acronyms and Terms (GOAT) with over 900 storage-related terms defined, which also doubles as an index back to the post (or posts) that use or further explain each term.
So who might be interested in this blook?
Business Partners and Sales Reps looking to give a nice gift to their best clients and colleagues
Managers looking to reward early-tenure employees and retain the best talent
IT specialists and technicians wanting a marketing perspective of the storage industry
Mentors interested in providing motivation and encouragement to their proteges
Educators looking to provide books for their classroom or library collection
Authors looking to write a blook themselves, to see how to format and structure a finished product
Marketing personnel that want to better understand Web 2.0, Second Life and social networking
Analysts and journalists looking to understand how storage impacts the IT industry, and society overall
College graduates and others interested in a career as a storage administrator
And yes, according to Lulu, if you order soon, you can have it by December 25.
