A [recent survey] conductedby Fleishman-Hillard Researchindicates that the majority of disk-only customers are now lookingat adding tape back into their infrastructure. Here are some excerpts:
"Over two thirds of surveyed businesses said they were lookingto add tape storage back into their overall network infrastructure and of those respondents, over80-percent plan to add tape storage solutions within the next 12 months.The survey, which was taken in the fourth quarter of 2007, focused on the views of morethan 200 network administrators and mid-level tech specialists at mid-size to large companiesthroughout the United States.
The integration of tape storage into a tiered information infrastructure is highly strategic forcustomers, due to its low cost of ownership, low energy consumption and portability for dataprotection, said Cindy Grossman, Vice President of Tape Storage Systems, IBM. LTO tapetechnology is a perfect choice for enterprise and mid-sized customer with its proven reliability, highcapacity, high performance and ability to address data security with built-in encryption and dataretention requirements for the evolving data center.
According to the survey, 58-percent of the respondents use a combination of disk and tapefor long term archiving, 24-percent use tape exclusively, and 18-percent employ a disk-onlyapproach. In this group, 68-percent of the current disk-only users plan to start using tape for longtermarchiving, and over half (58-percent) plan to add tape for short-term data protection.The survey findings suggest that disk-only users may be experiencing a bit of buyer sremorse, said David Geddes, senior vice president at Fleishman-Hillard Research, who oversawthe study. We found that a wide majority of companies that employ purely disk-basedapproaches are looking to quickly include tape in their backup and archiving strategies."
While disk provides online data access and availability, tape provides additional data protectionand security, lower total cost of ownership (TCO), lower energy consumption (Tape is more "green"),and can be an important part of a long term data retention and compliance strategy.
Disk is more costly, more energy hungry, and some data, although it must be retained, may seldom, if ever be looked at, so why keep it spinning?
Speaking of TCO, in a recent 5-year TCO analysis by the Clipper Group titled[“Disk and Tape Square Off Again”]stored 2.4PB of data long term on SATA disk and on an LTO tape library, the disk system was:23:1 more costly, used 290 times the amount of energy than tapeEven with a data dedupe system like IBM System Storage N series, disk was still 5 times more costly than the tape system.
The Linear Tape Open (LTO) consortium --consisting of IBM, Hewlett-Packard (HP) and Quantum-- just released its "LTO-5" plans. With 2:1 compression,you will be able to pack up to 3TB of data on a single tape cartridge. And while dollar-per-GB declinefor disk is slowing down to 25-30 percent per year, tape continues to decline at a healthy 40 percent rate, so the price gap between diskand tape will actually widen even further over the next few years.
A Brief History of SVC and Storwize Family: What, How and Why?
Fellow IBM Master Inventor [and blogger] Barry Whyte gave an excellent session on the past 10 years of development history for IBM SAN Volume Controller and the rest of the Storwize Family based on its binary code. The SAN Volume Controller represents the start of a movement, what is now called "Software-Defined Storage", with a layer of abstraction that completely hides the differences between different back-end devices. The Storwize family is the most successful Software-defined Storage solution in the IT industry!
IBM Cloud Storage Architectures
IBM Clod Barrera presented an updated version of his "Cloud Storage Architecture" pitch from a technical and strategic viewpoint. From 2011 to 2015, external storage spend is increasing 25 percent for public cloud, and 17 percent for private cloud deployments, and that is not including all of the Do-it-yourselfers like Facebook who build their own storage devices from piece parts.
This year, Clod has expanded his "Cloud Storage Taxonomy" to six different categories:
OLTP/transactional, typically block-based
General purpose storage
Ephemeral storage that exists only while a specific virtual machine (VM) is running
Analytics, which tends to be more sequential than random in I/O pattern
IBM is a platinum sponsor of OpenStack, and is proud to have hundreds of contributors assigned to improve this open source initiative.
IBM Linear Tape File System - Enterprise Edition
IBM Ed Childers presented the latest announcement on Linear Tape File System [LTFS]. For a quick recap, IBM first introduced LTFS Standard Drive Edition [LTFS-SDE] in April 2010, which allowed workstations attached to single tape drives to use cartridges much like USB memory sticks. Then, IBM introduced LTFS Library Edition [LTFS-LE] which allows an entire tape library to be mounted as a file system, with each resident tape cartridge listed as a sub-directory.
Now, IBM has LTFS Enterprise Edition, which combines disk-based General Parallel File System [GPFS] with LTFS-LE, resulting in a combined hybrid disk-and-tape file system.
To provide a client's perspective, Konstantin Arnold with Biozentrum, the Life Sciences Research department of the University of Basel, Switzerland and SIB Swiss Institute of Bioinformatics presented some shocking information on their data growth. Biozentrum studies 3D protein folding, with information from the Worldwide Protein Data Bank [PDB] and [UniProt], which combines protein information from Swiss-Prot with manually annotations and TrEMBL computationally analyzed and automatically annotated entries.
Combining lab data, proteomics, deep-sequencing, imaging and high-content analysis, their storage requirements has grown exponentially, from less than 50 TB in 2009, to over 350TB in 2013. With the need to have such a large repository of unstructured data, it made sense to use LTFS-EE for this project!
IBMers presented the use of SAN Volume Controller (SVC) in a "stretch cluster" for a production environment at a bank in the Middle East. Before going into the technical details of the solution, they explained the challenges of running a bank under Sharia law. For example, Sharia law does not allow charging interest rates on borrowed money, but banks can charge fees for services. Debit cards are automatically denied at shops that are "black-listed" such as liquor stores, that are not consistent with the precepts of the Islamic religion.
The SVC implementation was rather straight-forward. IBM has offered Stretch Cluster since 2009 with version 5.1, but it only gained popularity years later when VMware pointed out that this can be used for datacenter to datacenter vMotion activity. The IBM team tested this out with a short 500 meter distance locally, before stretching it out to two locations now implemented. They have three SVC nodes managing 60TB of managed disk capacity at each data center, made up from a mix of DS8870, Storwize V7000 and DS3950 disk systems.
To demonstrate the robustness of the solution, the client requested that the IBM team demonstrate various recovery scenarios while running live in production mode! As you would expect, IBM SVC successfully handled every one.
IBM Cloud Storage with OpenStack and IBM System Storage
IBM Michael Factor presented this overview of OpenStack, and how IBM already supports various aspects of the open source initiative with products like SAN Volume Controller, XIV, and Storwize V7000.
This was the best overview of OpenStack I had heard. IBM is a platinum sponsor of this open source initiative, managed by the [OpenStack Foundation]. In traditional open source fashion, bi-annual releases are given alphabetically-ascending names. The last release was named Folsom, the current release is Grizzly, and the next release planned will be named Havana.
OpenStack is designed to manage your data center or cloud across four capabilities: Compute, Network, Storage and Shared Services. For Compute, the "Nova" project focuses on managing running VM instances, and "Glance" manages VM images that can be launched. The "Networking" project focuses on providing network connectivity. This was formerly called "Quantum", but Quantum (the company) felt there might be some confusion, so it was renamed to just "Networking".
For Storage, there are two projects, "Cinder" and "Swift". Cinder refers to persistent, external block storage, accessible via iSCSI or Fibre Channel. IBM's SAN Volume Controller, XIV and Storwize V7000 already support the Cinder API interface. Swift is focused on "object storage", which can provide an alternative way of storing information for cloud-based applications. SNIA's Cloud Data Management Interface (CDMI) is working with OpenStack to bring object storage into the mainstream.
With the Cinder API, applications can create volumes, take snapshots, set quotas, and attach these volumes to VM instances.
I realize there is a big time gap between this post and my last. Where have I been? "Where haven't I been?"... might be the better question! After my week at Edge, I flew from Las Vegas to Sao Paulo, Brazil where various protests delayed my departure, then visited clients in the Midwestern USA, then London to watch a bit of tennis. From there, I flew to Athens, Greece (and yes, more protests!), took some overdue time-off on the beach on various Greek islands, then taught a Storage Top Gun class in Bangalore, India. So, yes, I have been quite busy. I will try to catch up on typing up all my notes from the IBM Edge conference over the next few weeks!
Continuing on my theme of storage area networking, today I thought I would coverstorage networking at home.
Before the PC, corporate end-users had dumb terminals (displays) connected to mainframes (servers) thatwere then connected to external disk and tape (storage devices). This was all done with direct cable connections,then later through networks. The PC solved this by putting the display, server and storage into one unit, makingit more accessible to smaller businesses and individuals.
Many years ago, Microsoft started out with the vision "A PC on every desktop".The primary reason we even have networks is while everyone might have had their own PC, not everyone had their own printer. (Printers used to be part of IBM's storage division, which we explained as "storage on PAPER"!)Maybe if Microsoft's vision was "A PC and printer on every desktop", history might have turned up different.
Disclaimer: IBM has close business relationships with both Apple and Microsoft and others,providing the chips inside some of their products. I discuss them here not only becauseI am trying to get you to buy their products, and let IBM benefit indirectly from their success, but because they are newsworthy, and relevant to the topic at hand.
The "Apple TV" is not a TV at all, but rather a server, one that lets your television (your dumb terminal)access the video, audio and photos stored on your Mac or iPod (the storage device), all through a home network.(Sound familiar?)
Bill Gates from Microsoft gave the keynote, and this is probably his last appearance, as he is retiring in 2008,as we are reminded by thisfunny video, to move on to bigger, and better things. It is perhaps fitting that his retirement aligns with the end of the era for the PC.
Microsoft unveiled their Microsoft Windows Home Server, again a server that connects your television (dumb terminal) with your PC or Zune (storage device)all through your home network. (Sound familiar, again?)
Whereas Apple above pretty much shunned the gaming community, Microsoft embraced it with their internet-enabled Xbox360.Microsoft sold 10.4 million of these last year, which was 400 million more than they projected.
Our SAN technology partner Cisco wants to get in on this "home networking craze", as written about inInfoWorld andCnet.
My take on all this...the consumer electronics industry is taking clues from IBM's mainframe business. Not the first time this has happened, and probably not the last.
I already access photos and audio with my Tivo, from both my Mac AND my PC,so not much new here for me. Getting my home network connected was one of mytech highlights of 2006 and organizing my audio content was done withILM for my iPod.
Bypassing the PC, by being able to have your television, handheld or phone access data directly will greatlyincrease the demand for storage from businesses that provide information and content, and for storage networking technology in the home. It will be interesting how this all plays out in 2007.
The [IBM Edge2015 conference] is premiere conference covering Infrastructure Innovations for IBM System Storage, as well as sessions about z Systems and POWER Systems from our IBM Enterprise conference.
Here is my quick recap of various sessions on the fourth day, Wednesday, May 14, 2015.
Object Storage and Its Use with OpenStack
Rich Swain, IBM Storage Team Lead Engineer, presented this in three sections. First, he covered the advantages of object storage versus block or file-based storage. This includes the idea that each object comes with rich metadata that can be searched.
Rich then went to explain the specifics of OpenStack Swift, an open standard for object storage. A simple three-tier hierarchy of account, container, and object.
Rich wrapped up his talk with an overview of Spectrum Scale and Elastic Storage Server offerings from IBM.
Driving Timely Business Insights on the IBM Data Engine for Analytics
Linton Ward, IBM Distinguished Engineer, POWER Systems Big Data and Analytics, presented Big Data analytics from a POWER Systems perspective. He gave an overview of Big Data analytics, and how IBM POWER Systems provide advantages to analyze data quickly.
Linton had helped me with my Big Data presentation, so I decided to participate in his presentation during his section on Spectrum Scale, but no questions came up that he couldn't handle on his own.
The Pendulum Swings Back -- Understanding Converged and Hyper-converged Environments
This presentation has an interesting back-story. At a client briefing, I was asked to explain the difference between "Converged" and "Hyper-converged" systems, which I did with the analogy of a pendulum. I used the whiteboard, and then later made it into a single chart.
At the far left, I start with mainframe systems of the early 1950s that had internal storage. As the pendulum swings to the middle, I discuss the added benefits of external storage, from RAID protection to centralized management.
To the far right, the pendulum swings over to networked storage, from NAS to SAN attached devices for flash, disk and tape. This offers excellent advantages, including greater host connectivity, and greater distances supported to help with things like disaster recovery.
Here is where the pendulum swings back. IBM introduced PureSystems that combined servers, storage and switches into a single rack configuration. Other vendors had similar offerings, such as VCE vBlock, Flexpod from NetApp and Cisco, and Oracle Exadata.
Lately, the pendulum has swung fully back to internal storage, with storage-rich servers running specialized software. There are two kinds. First there are pre-built systems like Nutanix, Simplivity or EVO:Rail which are x86 based server systems with built-in flash and disk. Second, there is software that can be deployed on your own choice of hardware, such as IBM Spectrum Scale FPO or VMware VSAN.
So, what I presented on a single slide before, has been fleshed out into a full blown hour-long presentation!
Common Performance Pitfalls and the Value of Latency
Erik Eyberg and Woody Hutsell from IBM FlashSystem team presented the differences between MB/sec, IOPS and latency. IBM FlashSystem is the world's fastest storage with incredibly low latency that is two to five times faster than most major competitors in the all-flash arrays category.
Accelerate with OpenStack: Flexible and Rapid Deployed Orchestration for Your Cloud
Ohad Atia, IBM Systems Development Manager for XIV Cloud Storage Solutions, presented how the OpenStack Cinder interface works, then explained the new IBM Spectrum Accelerate, based on the software from XIV.
Ronen Kat, IBM Research Manager and Cloud Storage Research Scientist, gave a live demo on how easy it is to deploy Spectrum Accelerate in a public cloud. First, you request three or more bare metal servers with specific amounts of RAM and spinning disk. Optionally, Spectrum Accelerate can support a single Solid State Driver (SSD) as read cache in each server. You can either install VMware ESXi 5.5 yourself, or have the Cloud provider do it for you. This step can be done quickly to initiate, but then the Cloud provider might take 24-72 hours depending on how busy they are.
Like cooking shows, where they take out an already prepared item from the oven or refrigerator to save time, Ronen started with four servers that were already configured above from IBM SoftLayer. The second step was to deploy the Spectrum Accelerate code, supplied as an OVF file that VMware can use to start up each virtual machine.
The third step is to connect all of the IP addresses, since Spectrum Accelerate uses TCP/IP for everything from iSCSI host attachment to inter-node communication.
Steps 2 and 3 took less than 5 minutes! I was impressed how simple and easy it was. Even when you factor in the few days it might take IBM SoftLayer to provide you access to the servers, it is still way faster than ordering your own on-premise storage.
A Powerful Virtualization Solutions Delivered by the VMware and IBM Storage Partnership
Impressed with their last presentation, I stayed in the room for this one. Ohad Atia presented IBM Spectrum Control Base edition, and how this provides VMware VVol support through its VASA 2.0 provider code.
IBM Spectrum Control Base edition is entitled to all IBM owners of XIV, Spectrum Accelerate, DS8000 and Storwize family products to provide a consistent VMware interface experience.
Storage Meet the Experts, hosted by Maurice McCullough
For those not familiar with Edge, Maurice "Mo" McCullough is the lead organizer of the storage portion of Technical Edge, as well as various Systems Technical University events held throughout the year.
On the Thursday evening of Edge every year, Mo hosts this popular session for everyone to ask their questions to the experts at the front of the room. There were similar sessions for z Systems and POWER Systems experts in the adjoining rooms.
Joining me on the storage expert panel were Clod Barrera, Shelly Howrigon, Mike Griese, Barry Whyte, Jim Blue, Sven Oehme, and several others. Generally, there isn't a question we don't have an answer to, but if you stump the panel, we will take you out to dinner. The audience was ready to take that challenge!
After Storage Meet the Experts, I had dinner and went to see [Frank: The Man, The Music] musical show at the Venetian hotel. Bob Anderson impersonates Frank Sinatra, singing a popular selection of Frank's many recordings, intermixed with highlights from his television and film career. Bob was accompanied by a 32-piece orchestra that brought the music of the era back to life.
IBM came out with their latest "5 in 5". These are five predictions for technologies that will havean impact over the next five years, summarized on 5 pages. Before I give my take on this year's set,here is a quick recap of[Last Year's 5 in 5]:
3-D representations of the human body to improve health care
This prediction is based on the idea that most medical mistakes result from lack of informationabout the patient. A 3-D avatar of the patient would allow the doctor to click on the section ofthe body, and this would trigger retrieval of patient records, relevant X-rays, MRI images, and so on.For example, IBM System Storage Grid Medical Archive Solution (GMAS) provides the storage that wouldallow any doctor to access these records, even if the image was taken at a different facility.
Unfortunately, this prediction only applies to patients who can actually afford to see a doctor. Apparently,no amount of technology, no matter how cool it is, can convince governments to make health care somethingeveryone has access to. Michael Moore has done a good job explaining this in his film documentary [Sicko].
Digital passport for food
Using RFID tags and second generation barcodes, you will have access to details of a food's origin,transportation conditions, and impact to the environment. Much of this information is already gathered,just not stored in a database accessible to the consumer.
Last year, the term "locavore" was the2007 Word of the Year for the Oxford American Dictionary, referring to people who limit what they eatto food produced within a certain radius, from family farms and locally-owned businesses.Here is an excerpt from a [Locavores] website:
Our food now travels an average of 1,500 miles before ending up on our plates. This globalization of the food supply has serious consequences for the environment, our health, our communities and our tastebuds.
Certainly, I am all for selling storage capacity to the food industry to help store vasts amount ofinformation for this, and certainly some people will be able to make smarter decisions based on thisinformation. This is not the first time this idea came up. The U.S. Food and Drug Administration introduced [nutrition labeling requirements] on thehope that people would choose more healthier foods. Despite this, people still opt for white bread, iceberg lettuce, and processed meats, so possibly having more information about where food comes from, and how it was transported, may not mean much to some consumers.
Technology to manage your own carbon footprint
"Smart energy" technologies allow you to walk the talk, by managing your own carbon footprint inyour home. For example, if you forgot to turn off the heat or air conditioner before leaving thehouse on your commute to work, your home would call your mobile phone, so that you can turn aroundand go back and correct that mistake. Better yet, IBM is working with others to provide web-enabledelectric meters that would allow you to turn off systems from work or cell phone browser.
Of course, such technology already exists for the data center. IBM Systems Director Active EnergyManager (AEM) allows you to monitor the actual usage of your servers and storage devices, and insome cases make adjustments to control energy consumption. This can feed into the IBM TivoliUsage and Accounting Manager software to incorporate energy usage as part of the charge-backcalculations. See the [IBM Press Release] formore details.
Cars that drive themselves
Not only will cars that drive themselves reduce the number of drunk-driving accidents, it canalso help reduce congestion in big cities, by routing traffic to different directions, based onGPS and presence-aware technologies. Stockholm (Sweden) has already reduced peak hour traffic by 20 percentusing this approach.
While I admire the concept, cars are perhaps the least energy-efficient mode of transportation.Often, a family can only afford a single vehicle, and it is purchased based on the worst-case scenario.A friend of mine has only two children, but a sever-person mini-van that gets only 17 MPG. Why suchan energy-inefficient vehicle? Because she occasionally drives her daughter and her friends tosoccer practice, and that represents the worst-case scenario, minimizing the parent/child ratio. Theother 99 percent of the time, she is driving by herself, or with one child, and consuming a lot ofgasoline in the process.
A better approach would be to find technology that connects airports, trains, buses and light rail forpublic transportation to greatly reduce the need to drive a car in the first place.
The idea that a family can have only one vehicle plays in the storage arena as well. Larger companiescan afford to have different storage for different workloads. The IBM System Storage DS8000 high-end disk system for their large OLTP anddatabase workloads, an XIV Nextra for their Web 2.0 storage needs, DR550 to hold their compliance data,and so on. Smaller companies are often tasked to find a single solution for all their needs, andfor them, IBM offers the IBM System Storage N series, providing a "unified storage" platform.
Increased dependence on cell phones
Before the cell phone, the last don't-leave-home-without-it technology most of us carried was the credit card. Now, IBM predicts that we will be even more dependent on our cell phones, becoming our banker, ticket broker, and shopping buddy.For example, you could use your cell phone to take a picture of a shirt at the mall, and it will then show you what youwould look like wearing that shirt, on a 3-D avatar representation of yourself, or perhaps your spouse, and getinformation on what discounts are available, or where else the shirt is being offered.
None of this example actually uses the "phone" part of the cell phone, however the cell phone is one device thatnearly everyone carries, so it becomes the development platform for all other technologies to be based on.
The common theme running through these is that it can be helpful to store more information than we do today,provided we make it accessible to the people who need it to make better decisions.
Continuing this week's theme, my team here at theTucson Executive Briefing Center (TEBC) have made these two videos for me, usingcloud-computing facilities from OfficeMax and the folks at JibJab.Only five people were allowed per video, so we had to make two to get everyone in.
If you have been to the Tucson Executive Briefing Center, perhaps you can recognizesome of our faces!
Despite this, or perhaps because of this, over 30 percent of IBM's Linux server revenue is onnon-x86 platforms, avoiding the XenSource vs. VMware decision altogether. Both System z (traditional mainframe servers) and System p (traditional UNIX servers) are able to run many Linux images in a fully virtualized manner, without VMware or XenSource.
In case you haven't noticed, IBM System Storage makes most of their announcements on Tuesdays. IBM announced a lot today, so here is a quick run-down.
Cisco storage networking products
IBM continues to resell Cisco switches and directors, but now can offer these with a 1-year IBM warranty.
The entry-level Cisco 9124offers 8 to 24 ports. For IBM BladeCenter, IBM now offers the Cisco10-port and 20-port modules that slide into the back of the chassis, and are functionally equivalent to the 9124.The original BladeCenter came with a 16-port module with 14 internal, but only 2 external, which severely hamperedbandwidth connectivity to external storage. These new modules provide more external ports to relieve that constraint.
The midrange Cisco9200switches have two models, both with 16 fixed ports, with the option for a blade that can provide 12, 24 or 48 additional ports. The 9216A has 16 FCP ports, and the 9216i has 14 FCP ports, and 2 GbE ports to act as a router, such as toconnect to a remote location for business continuity using Metro Mirror or Global Mirror.
The enterprise-class Cisco 9500directors can support up to 528 ports.
TS3400 Tape Library
The new TS3400library is a small entry-level size library, supporting the enterprise-class TS1120 drive, providing interoperabilitywith the larger tape libraries, with all the support for tape encryption.
In addition to Linux, Unix, and WIndows, the TS1120 can now be connected to System i servers. In the past, the only IBMtape available to System i were the LTO models. There are a lot of businesses that need to comply with government regulations that are looking for tape encryption, and now IBM has made it accessible to more clients.
300GB drives at 15K RPM
The DS8000 can now support new drives with 300GB capacity at 15,000 RPM (15K). These can be up to 30 percent faster than the 10,000 RPM drives for typical workloads.
IBM continues its market leadership with these new set of features and offerings!
Well, I have arrived safely in Las Vegas, and the [Forrester IT Forum 2009 conference] started today at noon, with a Welcome Reception at the Technology Showcase. As a platinum sponsor, IBM has a booth manned by several subject matter experts, on the fourth floor of the Sands Expo, between the Venetian and Palazzo hotels.
On the left side, we have Paula Koziol and our [Kaon Interactive] 3D touch-screen.
On the right side, we have Ira Chavis and Cris Espinosa, and a rack of some of IBM's latest offerings.
I'm here all week to blog about this event. When I am not in sessions, I will probably hang out at the Technology Showcase with my colleagues above. If you are in Las Vegas, and want to connect, please contact me.
I was in Raleigh this week, in business meetings, and had dinner last night at a Japanese Tepanyaki restaurant. The man next to me was dining alone, and said he worked for Cisco, a big company, "Had you heard of it?" he asked. Of course, I told him, I work for IBM, and IBM and Cisco have a strong working relationship, using each others products in both directions. He said he understood why they would use IBM, but why would IBM buy anything from them, and then he said, "Oh yes, your cafeteria".
At this point we realized he was talking about SYSCO, the food company, not Cisco, the storage networking technology partner. We both had a good laugh.
Which brings me to think of other "mis-heard" or "mis-interpreted" items that might have caught people off guard because they sounded similarly.
zFS versus ZFS
Some things are case-sensitive. Lower case zFS is the hierarchical file system for the z/OS mainframe environment, which was originally called "episode" file system that IBM acquired from TransArc. z/OS supports two file systems, HFS and zFS. Meanwhile, ZFS is one of the file systems available for Sun Solaris. Apple Mac OS is switching from its own HFS, different than the z/OS version, over the Sun's ZFS.
packs versus PACS
Older mainframers call disk volumes "packs". This started in the days where disks were "removable" and you can pack and unpack them into the drive unit.
PACS on the other hand refers to the "Picture Archive and Communication System" application environment used by hospitals and medical facilities to storage and share X-ray, Cardiology and Radiology images. Today, modern medical equipment are called "modalities" and directly connect to NAS storage via NFS or CIFS protocols. The images are immediately digitized and sent to disk, then tape, for long-term archive storage. IBM's Grid Medical Archive Solution (GMAS) is designed specifically for this environment.
rack versus RAC
Perhaps my favorite was when someone asked a high-level executive at a conference if their storage product supported Oracle RAC, and the response was that it supported anyone's rack, so long as it met the 19 inch standard. Everyone burst out laughing, and he probably had to be explained what was going on afterward.
Oracle RAC refers to Real Application Cluster, allowing multiple Oracle servers to work together as a system. A "rack" is just the powered shelf, typically 19" wide, and typically 25U or 42U tall, that allows modular servers, storage or network gear be placed together in a data center. A "U" is 1.75 inches, the thickness of a "two-by-four" piece of lumber. If you have ever used a 3.5 inch or 5.25 inch floppy diskette, then you already know the 2U and 3U sizes.
I am sure there are many other examples of similar sounding terms and phrases. If you have any to contribute, post a comment below!
The [IBM Edge2015 conference] is premiere conference covering Infrastructure Innovations for IBM System Storage, as well as sessions about z Systems and POWER Systems from our IBM Enterprise conference.
Here is a quick recap of my sessions I presented on the third day, Wednesday, May 13, 2015.
New Generation of Storage Tiering: Less Management, Lower Costs and Increased Performance
I organized this into three sections. In the first section, I talked about single-system optimization by moving extents within single volumes on a single system. For IBM, I focused on Easy Tier on DS8000 as an example of this methodology, and all the enhancements IBM introduced since its introduction, including Easy Tier Server, Easy Tear Application API, and Easy Tear Heat Map Transfer utility.
In the second section, I covered data center optimization using Spectrum Control Storage Analytics Engine. This involves moving entire volumes/LUNs from one storage system to another. At IBM's Boulder Facility, this methodology saved $17 million dollars per year, roughly 50 percent reduction of its storage budget.
The third section covered the global optimization with Information Lifecycle Management (ILM), Hierarchical storage Management (HSM) and Active File Management (AFM) features in Spectrum Scale. This provides a seamless movement of data from flash to disk to tape media. Spectrum Scale has been around in one form or another since 1998, and over 200 of the TOP500 supercomputers are using it today.
At the IBM Edge conference last year,IBM announced "Codename: Elastic Storage." IBM had to rename its General Parallel File System (GPFS) because it is not just a file system for two very good reasons:
Spectrum Scale can support volumes, files and objects.
Spectrum Scale provides active data management, including Information Lifecycle Management (ILM), Hierarchical storage Management (HSM) and Active File Management (AFM) features.
This year, IBM now has several offerings: Spectrum Scale software, Elastic Storage Server pre-built system, Storwize V7000 Unified pre-built system, and Elastic Storage on IBM Managed Cloud services.
IBM Winning Edge - CASE Training
IBM Winning Edge is focused on Business Partner and IBM seller training. Part of this is CASE (Cloud and Analytics Sales Enablement). I co-presented "Systems Infrastructure Offerings for Cloud" with Elan Freedberg.
For Wednesday evening, I had dinner with Dr. Steve Hetzler, IBM Almaden Research, to discuss his paper on "touch rate" that Clod Barrera mentioned at the Monday kickoff.
Later that evening, I was invited to enjoy some champagne and cigars with Eric Herzog, Jamie Thomas and other IBM Executives. I brought along fellow blogger Elisabeth Stahl, who recently was promoted to Distinguished Engineer!
On StorageZilla, fellow blogger Mark Twomey introduces the latest entrant from EMC to the blogosphere,in his post [Polly Pearson's blog].
Although we share the same name, with the same exact spelling, I would like be the first to point out we are not related, at least as far as I know. Basing solely from her post[Welcome to my Blog - Part 1], sheis a year younger than I am, a lot better looking, majored in communications, and is not afraid to quit acrappy job for a much better job elsewhere. I on the other hand, majored in engineering, but agree wholeheartedly not to stick in a crappy situation. There is such a skills shortage out there in the IT industry,with a cap on U.S. [H-1B visas] at a paltry [65,000 this year]. If you don't like your IT job, you should be able toquit and find another one in the IT industry you are more passionate about.
On a similar theme, over at DrunkenData, Jon Toigo's latest post asks if you are[Feeling Insecure About Your Job?]ScoreLogix’s Job Security Index has fallen in the United States, with a sharp drop specifically for IT jobs. Jon points out that while it might be easy to point out that a number went up or down, it is far more difficultto explain why it did so. He gives a good piece of career advice:
Want to keep your job? Play by the rules of the front office: demonstrate the value of what you do for the company from the standpoint of cost-savings, risk reduction and process improvement. Make yourself indispensable. If they don’t appreciate you then, you need to move on. You will always be hiding in your cubical and sweating a pink slip ...
So shine bright. Be remarkable. It is not always easy to communicate your value in a technical position to cluelessnon-technical managers. Certainly, writing a blog helps. Within IBM, there are over 3500 bloggers. Most postwithin the safe confines behind the firewall, but manage to generate ideas, present valid arguments, and get theconversation rolling with the right set of people that might be difficult otherwise in a company like IBM of over350,000 employees scattered around the world. A few of us daringly blog in full public, and carry the conversationto our clients, prospects, analysts, journalists, Business Partners, and others within the IT industry.
So, Polly Pearson from EMC, although we have never met in person, I too welcome you to the blogosphere!
The [IBM Edge2015 conference] is premiere conference covering Infrastructure Innovations for IBM System Storage, as well as sessions about z Systems and POWER Systems from our IBM Enterprise conference.
Here is my quick recap of my fifth and final day, Friday, May 15, 2015.
At the Systems Technical University in Prague last month, I had submitted "IBM Spectrum Storage overview", while another speaker submitted "Storage Integration with OpenStack" and somehow the two topics got merged into a single title "IBM Spectrum Storage Integration with OpenStack" through perhaps some cut-and-paste error.
I first had to explain the basics of OpenStack, how OpenStack manages pools of compute, storage and network resources. Then I explained specific details on Cinder, Swift and Manila interfaces. Finally, having laid the groundwork and reviewed the basics, I was able to explain how IBM's various storage offerings support these OpenStack interfaces.
The feedback from the audience was that this should have been presented earlier in the week! Attendees mentioned that other presentations earlier in the week merely assumed the audience was already familiar with OpenStack concepts and terminology, which obviously is not the case.
Storwize V7000 Unified with Spectrum Scale (formerly Elastic Storage)
Cameron McAllister, IBM Systems Architect for Spectrum Scale, presented an overview how Storwize V7000 Unified can interconnect with IBM Spectrum Scale deployments. The secret is a feature in both called Active File Management (AFM).
Shankar Balasubramanian, IBM Senior Technical Staff Member for Active File Management, went into details on how to set up Active File Management for a variety of use cases. For example, you could have Storwize V7000 Unified boxes in Remote Office/Branch Office (ROBO) locations replicating data to a centralized Spectrum Scale datacenter.
This week was a great conference! I received great feedback overall from many attendees about all the quality presentations they enjoyed this week.
Next year, Edge will be held in October 10-14, 2016. Save the date! Mark your calendars now!
