Well, today's Tuesday, and you know what that means... IBM Announcements!
This week, IBM has their huge 3Q Launch. This on top of the [2Q results] IBM released yesterday. You can read how the rest of the company did, but it is good to see that IBM grew in both revenue and market share for storage!
As with any IBM launch of this magnitude, there are so many enhancements, I will spread them across several posts.
IBM System Storage TS7610 ProtecTIER® Deduplication Appliance Express
The TS7610 is a smaller appliance than the TS7650 we introduced last year, taking up only 3U of rack space (2U for the disk itself, and a 1U slide rail to simplify maintenance). This is designed for smaller deployments, such as midsized businesses between 100 and 1000 employees that backup 3TB of data per week or less. The unit relies on RAID protected SATA drives. Thanks to the same ProtecTIER data deduplication we have on the TS7650, the TS7610 can hold up to 135TB of backup data on just 5.4TB of disk capacity, with in-line data ingest at 80 MB/sec performance. This little Virtual Tape Library (VTL) emulates up to four TS3500 libraries, with 64 LTO-3 drives and over 8000 virtual tapes. See the [Announcement letter] for details.
The [ProtecTIER Entry Edition] offers a hub-and-spoke approach to replication. You can have up to twelve(12) TS7610 boxes (the "spokes") replicate to a central VTL (the "hub"). This can be ideal for protecting remote office or branch office deployments.
IBM dobules the storage capacity by utilizing 2TB hard disk drives for the N3300 and N3400 series models, maximizes customer satisfaction through Partner Select Bundles (software bundles) for all of the N3000 series (N3300, N3400, N3600), and offers Application and Server Packs (software bundles) for N3400 models.
For the high-end, IBM introduces an enhanced Performance Acceleration Module (PAM II) bundle for N7900 Gateway. This bundle includes two 512GB Solid State Drive PAM II adapters, two dual-port 10GbE TOE network interface cards (NIC), and various software features.
The DS5020 and EXP520 joins their bigger siblings DS5100 and DS5300 in supporting Solid State Drives (SSD), available in 73GB and 300GB capacities. A new air filter bezel is also available for these when used in dusty environments. See the [Announcement letter] for details.
For my friends down in Brazil, A new 2.8 meter length power cord that supports 220-250 volts is now available for all DS4000 and DS5000 series disk systems. Obrigado para o seu negócio!
IBM Tivoli Storage FlashCopy Manager v2.2
I covered this latest release in my post [FlashCopy Manager v2.2] but the marketing team felt we should include it with this launch to get added exposure and visibility.
I'll try to get to the rest in separate posts over the rest of this week.
If Eskimos have 37 words for "snow", then EMC has perhaps a similar number of names for "failure". I have already covered a few of their past attempts, including [ATMOS], [Invista], and [VPLEX]. Last week, EMC introduced its latest, called XtremeIO.
But rather than focus on XtremeIO's many shortcomings, I thought it would be better to point out the highlights of IBM's All-Flash array, IBM FlashSystem.
But first, a quick story.
Two years ago, I worked the booth at [Oracle OpenWorld 2011]. After a conference attendee had visited the booths of Violin Memory and Pure Storage, he asked me why IBM did not have an all-Flash array.
Of course IBM did, and I showed him the [Storwize V7000]. For example, a 2U model with 18 SSD drives of 400GB each, configured in two RAID-5 ranks 7+P+S could offer 5.6 TB of space, running up to 250,000 IOPS at sub-millisecond response times.
Why didn't IBM advertise the Storwize V7000 as an all-Flash array? I though the question was silly at the time, since the Storwize V7000 supported SSD, 15K, 10K and 7200 RPM spinning disk, it seemed obvious that it could be configured with only SSD if you chose.
Since then, IBM has added 800GB support to the Storwize V7000, doubling the capacity. More importantly, IBM acquired Texas Memory Systems, and offers a much better all-Flash array.
Flash can be deployed in three levels. The first is in the server itself, such as with PCiE cards containing Flash chips, limited to applications running on that server only.
The second option is a hybrid disk system, that can intermix Flash-based Solid State Drives (SSD) with regular spinning hard disk drives (HDD). These can be attached to many servers.
The problem with this approach is that when Flash is packaged to pretend to be spinning disk, it undermines some of the performance benefits. Traditional disk system architectures using SCSI commands over Device adapter loops can introduce added latency.
The third fits snuggly in the middle: all-Flash arrays designed from the ground up to be only Flash.
Whereas SSD can typically achieve an I/O latency in the 300 to 1000 microseconds range, IBM FlashSystem can process I/O in the 25 to 110 microsecond range. That is a huge difference!
(FTC Disclosure: The U.S. Federal Trade Commission requires that I mention that I am an IBM employee, and that this post may be considered a paid, celebrity endorsement of both the IBM FlashSystem and IBM Storwize family of products. I have no financial interest in EMC, do not endorse the XtremeIO mentioned here, and was not paid to mention their company or products in any manner.)
Fellow blogger and IBM Master Inventor Barry Whyte has a great comparison table in his blog post [Extreme Blogging]. I thought I would add an added column for the Storwize V7000 with 18 Solid State drives.
IBM FlashSystem 820
IBM Storwize V7000 with SSD

11 Terabytes: 2U
7 Terabytes: 6U
I/O latency (microseconds)
110us (~5x faster)
Maximum I/O per second

While it is easy to show that EMC's XtremeIO does not hold a candle to IBM FlashSystems, I think it is more amusing that it is not even as good as a Storwize V7000 with SSD that IBM offered two years ago, long before [EMC acquired XtremeIO company] back in May 2012.
The new [IBM System Storage Tape Controller 3592 Model C07] is an upgrade to the previous C06 controller. Like the C06, the new 3592-C07 can have up to four FICON (4Gbps) ports, four FC ports, and connect up to 16 drives. The difference is that the C07 supports 8Gbps speed FC ports, and can support the [new TS1140 tape drives that were announced on May 9]. A cool feature of the C07 is that it has a built-in library manager function for the mainframe. On the previous models, you had to have a separate library manager server.
Crossroads ReadVerify Appliance (3222-RV1)
IBM has entered an agreement to resell [Crossroads ReadVerify Appliance], or "RV1" for short. The RV1 is a 1U-high server with software that gathers information on the utilization, performance and health for a physical tape environment, such as an IBM TS3500 Tape Library. The RV1 also offers a feature called "ArchiveVerify" which validates long-term retention archive tapes, providing an audit trail on the readability of tape media. This can be useful for tape libraries attached behind IBM Information Archive compliance storage solution, or the IBM Scale-Out Network Attached Storage (SONAS).
As an added bonus, Crossroads has great videos! Here's one, titled [Tape Sticks]
Linear Tape File System (LTFS) Library Edition Version 2.1
While the hardware is all refreshed, the overall "scale-out" architecture is unchanged. Kudos to the XIV development team for designing a system that is based entirely on commodity hardware, allowing new hardware generations to be introduced with minimal changes to the vast number of field-proven software features like thin provisioning, space-efficient read-only and writeable snapshots, synchronous and asynchronous mirroring, and Quality of Service (QoS) performance classes.
The new XIV Gen3 features an Infiniband interconnect, faster 8Gbps FC ports, more iSCSI ports, faster motherboard and processors, SAS-NL 2TB drives, 24GB cache memory per XIV module, all in a single frame IBM rack that supports the IBM Rear Door Heat Exchanger. The results are a 2x to 4x boost in performance for various workloads. Here are some example performance comparisons:
Disclaimer: Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. Your mileage may vary.
In a Statement of Direction, IBM also has designed the Gen3 modules to be "SSD-ready" which means that you can insert up to 500GB of Solid-State drive capacity per XIV module, up to 7.5TB in a fully-configured 15 module frame. This SSD would act as an extension of DRAM cache, similar to how Performance Accelerator Modules (PAM) on IBM N series.
IBM will continue to sell XIV Gen2 systems for the next 12-18 months, as some clients like the smaller 1TB disk drives. The new Gen3 only comes with 2TB drives. There are some clients that love the XIV so much, that they also use it for less stringent Tier 2 workloads. If you don't need the blazing speed of the new Gen3, perhaps the lower cost XIV Gen2 might be a great fit!
As if I haven't said this enough times already, the IBM XIV is a Tier-1, high-end, enterprise-class disk storage system, optimized for use with mission critical workloads on Linux, UNIX and Windows operating systems, and is the ideal cost-effective replacement for EMC Symmetrix VMAX, HDS USP-V and VSP, and HP P9000 series disk systems, . Like the XIV Gen2, the XIV Gen3 can be used with IBM System i using VIOS, and with IBM System z mainframes running Linux, z/VM or z/VSE. If you run z/OS or z/TPF with Count-Key-Data (CKD) volumes and FICON attachment, go with the IBM System Storage DS8000 instead, IBM's other high-end disk system.
Miles per Gallon measures an effeciency ratio (amount of work done with a fixed amount of energy), not a speed ratio (distance traveled in a unit of time).
Given that IOPs and MB/s are the unit of "work" a storage array does, wouldn't the MPG equivalent for storage be more like IOPs per Watt or MB/s per Watt? Or maybe just simply Megabytes Stored per Watt (a typical "green" measurement)?
You appear to be intentionally avoiding the comparison of I/Os per Second and Megabytes per Second to Miles Per Hour?
May I ask why?
This is a fair question, Barry, so I will try to address it here.
It was not a typo, I did mean MPG (miles per gallon) and not MPH (miles per hour). It is always challenging to find an analogy that everyone can relate to explain concepts in Information Technology that might be harder to grasp. I chose MPG because it was closely related to IOPS and MB/s in four ways:
MPG applies to all instances of a particular make and model. Before Henry Ford and the assembly line, cars were made one at a time, by a small team of craftsmen, and so there could be variety from one instance to another. Today, vehicles and storage systems are mass-produced in a manner that provides consistent quality. You can test one vehicle, and safely assume that all similar instances of the same make and model will have the similar mileage. The same is true for disk systems, test one disk system and you can assume that all others of the same make and model will have similar performance.
MPG has a standardized measurement benchmark that is publicly available. The US Environmental Protection Agency (EPA) is an easy analogy for the Storage Performance Council, providing the results of various offerings to chose from.
MPG has usage-specific benchmarks to reflect real-world conditions.The EPA offers City MPG for the type of driving you do to get to work, and Highway MPG, to reflect the type ofdriving on a cross-country trip. These serve as a direct analogy to SPC having SPC-1 for Online transaction processing (OLTP) and SPC-2 for large file transfers, database queries and video streaming.
MPG can be used for cost/benefit analysis.For example, one could estimate the amount of business value (miles travelled) for the amount of dollar investment (cost to purchase gallons of gasoline, at an assumed gas price). The EPA does this as part of their analysis. This is similar to the way IOPS and MB/s can be divided by the cost of the storage system being tested on SPC benchmark results. The business value of IOPS or MB/s depends on the application, but could relate to the number of transactions processed per hour, the number of music downloads per hour, or number of customer queries handled per hour, all of which can be assigned a specific dollar amount for analysis.
It seemed that if I was going to explain why standardized benchmarks were relevant, I should find an analogy that has similar features to compare to. I thought about MPH, since it is based on time units like IOPS and MB/s, butdecided against it based on an earlier comment you made, Barry, about NASCAR:
Let's imagine that a Dodge Charger wins the overwhelming majority of NASCAR races. Would that prove that a stock Charger is the best car for driving to work, or for a cross-country trip?
Your comparison, Barry, to car-racing brings up three reasons why I felt MPH is a bad metric to use for an analogy:
Increasing MPH, and driving anywhere near the maximum rated MPH for a vehicle, can be reckless and dangerous,risking loss of human life and property damage. Even professional race car drivers will agree there are dangers involved. By contrast, processing I/O requests at maximum speed poses no additional risk to the data, nor possibledamage to any of the IT equipment involved.
While most vehicles have top speeds in excess of 100 miles per hour, most Federal, State and Local speed limits prevent anyone from taking advantage of those maximums. Race-car drivers in NASCAR may be able to take advantage of maximum MPH of a vehicle, the rest of us can't. The government limits speed of vehicles precisely because of the dangers mentioned in the previous bullet. In contrast, processing I/O requests at faster speeds poses no such dangers, so the government poses no limits.
Neither IOPS nor MB/s match MPH exactly.Earlier this week,I related IOPS to "Questions handled per hour" at the local public library, and MB/s to "Spoken words per minute" in those replies. If I tried to find a metric based on unit type to match the "per second" in IOPS and MB/s, then I would need to find a unit that equated to "I/O requests" or "MB transferred" rather than something related to "distance travelled".
In terms of time-based units, the closest I could come up with for IOPS was acceleration rate of zero-to-sixty MPH in a certain number of seconds. Speeding up to 60MPH, then slamming the breaks, and then back up to 60MPH, start-stop, start-stop, and so on, would reflect what IOPS is doing on a requestby request basis, but nobody drives like this (except maybe the taxi cab drivers here in Malaysia!)
Since vehicles are limited to speed limits in normal road conditions, the closest I could come up with for MB/s would be "passenger-miles per hour", such that high-occupancy vehicles like school buses could deliver more passengers than low-occupancy vehicles with only a few passengers.
Neither start-stops nor passenger-miles per hour have standardized benchmarks, so they don't work well for comparisonbetween vehicles.If you or anyone can come up with a metric that will help explain the relevance of standardized benchmarks better than the MPG that I already used, I would be interested in it.
You also mention, Barry, the term "efficiency" but mileage is about "fuel economy".Wikipedia is quick to point out that the fuel efficiency of petroleum engines has improved markedly in recent decades, this does not necessarily translate into fuel economy of cars. The same can be said about the performance of internal bandwidth ofthe backplane between controllers and faster HDD does not necessarily translate to external performance of the disk system as a whole. You correctly point this out in your blog about the DMX-4:
Complementing the 4Gb FC and FICON front-end support added to the DMX-3 at the end of 2006, the new 4Gb back-end allows the DMX-4 to support the latest in 4Gb FC disk drives.
You may have noticed that there weren't any specific performance claims attributed to the new 4Gb FC back-end. This wasn't an oversight, it is in fact intentional. The reality is that when it comes to massive-cache storage architectures, there really isn't that much of a difference between 2Gb/s transfer speeds and 4Gb/s.
Oh, and yes, it's true - the DMX-4 is not the first high-end storage array to ship a 4Gb/s FC back-end. The USP-V, announced way back in May, has that honor (but only if it meets the promised first shipments in July 2007). DMX-4 will be in August '07, so I guess that leaves the DS8000 a distant 3rd.
This also explains why the IBM DS8000, with its clever "Adaptive Replacement Cache" algorithm, has such highSPC-1 benchmarks despite the fact that it still uses 2Gbps drives inside. Given that it doesn't matter between2Gbps and 4Gbps on the back-end, why would it matter which vendor came first, second or third, and why call it a "distant 3rd" for IBM? How soon would IBM need to announce similar back-end support for it to be a "close 3rd" in your mind?
I'll wrap up with you're excellent comment that Watts per GB is a typical "green" metric. I strongly support the whole"green initiative" and I used "Watts per GB" last month to explain about how tape is less energy-consumptive than paper.I see on your blog you have used it yourself here:
The DMX-3 requires less Watts/GB in an apples-to-apples comparison of capacity and ports against both the USP and the DS8000, using the same exact disk drives
It is not clear if "requires less" means "slightly less" or "substantially less" in this context, and have no facts from my own folks within IBM to confirm or deny it. Given that tape is orders of magnitude less energy-consumptive than anything EMC manufacturers today, the point is probably moot.
I find it refreshing, nonetheless, to have agreed-upon "energy consumption" metrics to make such apples-to-apples comparisons between products from different storage vendors. This is exactly what customers want to do with performance as well, without necessarily having to run their own benchmarks or work with specific storage vendors. Of course, Watts/GB consumption varies by workload, so to make such comparisons truly apples-to-apples, you would need to run the same workload against both systems. Why not use the SPC-1 or SPC-2 benchmarks to measure the Watts/GB consumption? That way, EMC can publish the DMX performance numbers at the same time as the energy consumption numbers, and then HDS can follow suit for its USP-V.
I'm on my way back to the USA soon, but wanted to post this now so I can relax on the plane.
Well, it's 2008, which could mark the end to RAID5 and mark the beginnings of a new disk storagearchitecture. IBM starts the year with exciting news, acquiring new disk technology from a smallstart-up called XIV, led by former-EMCer Moshe Yanai. Moshe was ousted publicly in 2001 from hisposition as EMC's VP of engineering, and formed his own company. It didn't take long for EMC bloggersto poke fun at this already. Mark Twomey, in his StorageZilla blog, had mentioned XIV before back in August,[XIV], and again todayin [IBM Buys XIV].
To address the new requirements associated with next generation digital content, IBM chose XIV and its NEXTRA™ architecture for its ability to scale dynamically, heal itself in the event of failure, and self-tune for optimum performance, all while eliminating the significant management burden typically associated with rapid growth environments. The architecture also is designed to automatically optimize resource utilization of all the components within the system, which can allow for easier management and configuration and improved performance and data availability.
"We are pleased to become a significant part of the IBM family, allowing for our unique storage architecture, our engineers and our storage industry experience to be part of IBM's overall storage business," said Moshe Yanai, chairman, XIV. "We believe the level of technological innovation achieved by our development team is unparalleled in the storage industry. Combining our storage architectural advancements with IBM's world-wide research, sales, service, manufacturing, and distribution capabilities will provide us with the ability to have these technologies tackle the emerging Web 2.0 technology needs and reach every corner of the world."
The NEXTRA architecture has been in production for more than two years, with more than four petabytes of capacity being used by customers today.
Current disk arrays were designed for online transaction processing (OLTP) databases. The focus was onusing fastest most expensive 10K and 15K RPM Fibre Channel drives, with clever caching algorithmsfor quick small updates of large relational databases. However, the world is changing, and peoplenow are looking for storage designed for digital media, archives, and other Web 2.0 applications.
One problem that NEXTRA architecture addresses is RAID rebuild. In a standard RAID5 6+P+S configuration of 146GB 10K RPM drives, the loss of one disk drive module (DDM) was recovered by reconstructing the data from parity of the other drives onto the spare drive. The process took46 minutes or longer, depending on how busy the system was doing other things. During this time,if a second drive in the same rank fails, all 876GB of data are lost. Double-drive failures are rare,but unpleasant when they happen, and hopefully you have a backup on tape to recover the data from.Moving to slower, less expensive SATA drives made this situation worse. The drives have highercapacity, but run at slower speeds. When a SATA drive fails in a RAID5 array, it could take severalhours to rebuild, and that is more time exposure for a second drive failure. A rebuild for a 750GBSATA drive would take five hours or more,with 4.5 TB of data at risk during the process if a second drive failure occurs.
The Nextra architecture doesn't use traditional RAID ranks or spare DDMs. Instead, data is carved up into 1MBobjects, and each object is stored on two physically-separate drives. In the event of a DDM loss, allthe data is readable from the second copies that are spread across hundreds of drives. New copies aremade on the empty disk space of the remaining system. This process can be done for a lost 750GB drive in under20 minutes. A double-drive failure would only lose those few objects that were on both drives, so perhaps1 to 2 percent of the total data stored on that logical volume.
Losing 1 to 2 percent of data might be devastating to a large relational database, as this could impactthe entire access to the internal structure. However, this box was designed for unstructuredcontent, like medical images, music, videos, Web pages, and other discrete files. In the event of a double-drivefailure, individual files would be recovered, such as with IBM Tivoli Storage Manager backup software.
IBM will continue to offer high-speed disk arrays like the IBM System Storage DS8000 and DS4800 for OLTP applications, and offer NEXTRA for this new surge in digital content of unstructured data. Recognizing this trend, diskdrive module manufacturers will phase out 10K RPM drives, and focus on 15K RPM for OLTP, and low-speedSATA for everything else.
Update: This blog post was focused on the version of XIV box available as of January 2008 that was built by XIV prior to the IBM acquisition. IBM has since made a major revision, made available August 2008 thataddresses a variety of workloads, including database, OLTP, email, as well as digital content and unstructuredfiles. Contact your IBM or IBM Business Partner for the latest details!
Bottom line, IBM continues to celebrate the new year, while the EMC folks in Hopkington, MA will continue to nurse their hangovers. Now that's a good way to start the new year!
Well, it's Wednesday, and you know what that means... IBM Announcements!
(Actually most IBM announcements are on Tuesdays, but IBM gave me extra time to recover from my trip to Europe!)
Today, IBM announced [IBM PureSystems], a new family of expert-integrated systems that combine storage, servers, networking, and software, based on IBM's decades of experience in the IT industry. You can register for the [Launch Event] today (April 11) at 2pm EDT, and download the companion "Integrated Expertise" event app for Apple, Android or Blackberry smartphones.
(If you are thinking, "Hey, wait a minute, hasn't this been done before?" you are not alone. Yes, IBM introduced the System/360 back in 1964, and the AS/400 back in 1988, so today's announcement is on scheduled for this 24-year cycle. Based on IBM's past success in this area, others have followed, most recently, Oracle, HP and Cisco.)
Initially, there are two offerings:
IBM PureFlex™ System
IBM PureFlex is like IaaS-in-a-box, allowing you to manage the system as a pool of virtual resources. It can be used for private cloud deployments, hybrid cloud deployments, or by service providers to offer public cloud solutions. IBM drinks its own champagne, and will have no problem integrating these into its [IBM SmartCloud] offerings.
To simplify ordering, the IBM PureFlex comes in three tee-shirt sizes: Express, Standard and Enterprise.
IBM PureFlex is based on a 10U-high, 19-inch wide, standard rack-mountable chassis that holds 14 bays, organized in a 7 by 2 matrix. Unlike BladeCenter where blades are inserted vertically, the IBM PureFlex nodes are horizontal. Some of the nodes take up a single bay (half-wide), but a few are full-wide, take up two bays, the full 19-inch width of the chassis. Compute and storage snap in the front, while power supplies, fans, and networking snap in the back. You can fit up to four chassis in a standard 42U rack.
Unlike competitive offerings, IBM does not limit you to x86 architectures. Both x86 and POWER-based compute nodes can be mixed into a single chassis. Out of the box, the IBM PureFlex supports four operating systems (AIX, IBM i, Linux and Windows), four server hypervisors (Hyper-V, Linux KVM, PowerVM, and VMware), and two storage hypervisors (SAN Volume Controller and Storwize V7000).
There are a variety of storage options for this. IBM will offer SSD and HDD inside the compute nodes themselves, direct-attached storage nodes, and an integrated version of the Storwize V7000 disk system. Of course, every IBM System Storage product is supported as external storage. Since Storwize V7000 and SAN Volume Controller support external virtualization, many non-IBM devices will be supported automatically as well.
Networking is also optimized, with options for 10Gb and 40Gb Ethernet/FCoE, 40Gb and 56Gb Infiniband, 8Gbps and 16Gbps Fibre Channel. Much of the networking traffic can be handled within the chassis, to minimize traffic on external switches and directors.
For management, IBM offers the Flex System Manager, that allows you to manage all the resources from a single pane of glass. The goal is to greatly simplify the IT lifecycle experience of procurement, installation, deployment and maintenance.
IBM PureApplication™ System
IBM PureApplication is like PaaS-in-a-box. Based on the IBM PureFlex infrastructure, the IBM PureApplication adds additional software layers focused on transactional web, business logic, and database workloads. Initially, it will offer two platforms: Linux platform based on x86 processors, Linux KVM and Red Hat Enterprise Linux (RHEL); and a UNIX platform based on POWER7 processors, PowerVM and AIX operating system. It will be offered in four tee-shirt sizes (small, medium, large and extra large).
In addition to having IBM's middleware like DB2 and WebSphere optimized for this platform, over 600 companies will announce this week that they will support and participate in the IBM PureSystems ecosystem as well. Already, there are 150 "Patterns of Expertise" ready to deploy from IBM PureSystem Centre, a kind of a "data center app store", borrowing an idea used today with smartphones.
By packaging applications in this manner, workloads can easily shift between private, hybrid and public clouds.
If you are unhappy with the inflexibility of your VCE Vblock, HP Integrity, or Oracle ExaLogic, talk to your local IBM Business Partner or Sales Representative. We might be able to buy your boat anchor off your hands, as part of an IBM PureSystems sale, with an attractive IBM Global Financing plan.
As a consultant, I am often asked to help design the architecture for the information infrastructure. A usefulanalogy to gather requirements and preferences is the difference between area rugs and wall-to-wall carpeting. Arearugs are not secured to the floor and cover only a portion of the floor area. Carpets are generally tacked or cemented to the floor, often with an underlay of cushion padding, stretched across the entire floor surface, out to all four walls of each room.
Each has its pros and cons, and often is a matter of preference. Some people like area rugs because they can choosea different style for each room, match the decor and color scheme of furniture, and use these to define each livingspace. Ever since paleolithic man put animal skins on the floor of their cave, people recognize that cold, hard andugly floors could be covered up with something soft and more attractive.Others prefer wall-to-wall carpeting because they want to walk around the house barefoot, have their young children crawl on their hands and knees, and give the entire house a unified look and feel. This is often an inexpensive option when compared against the cost of individual rugs.
The same is true for an information infrastructure. For some, they prefer the "area rug" approach: this style ofstorage for their email, this other type of storage for their databases, and perhaps a third for their unstructuredfile systems. When customers ask what storage would I recommend for their SAP application, or their Microsoft Exchangeemail environment, or their Business Intelligence (BI) software, I recognize they are taking this "area rug" approach.
Like area rugs, having different storage can focus on specific attributes of the workload characteristics. It alsoinsulates against company-wide changes, the dreaded "rip-and-replace" of replacing all of your storage with somethingfrom a different vendor. With "area rug" storage, you can support a dual-vendor or multi-vendor strategy, and upgrade or replace each on its own schedule.
Thanks to open standards and industry-standard benchmarks, changing out one storage solution for another is assimple as rolling up an area rug, and putting another one in its place that is similar in size dimensions.
Others may prefer "wall-to-wall carpeting" approach: one disk system type, one tape library type,one network type, that provides unified management and minimizes the needs for unique skills. Generally, the choice of NAS, SAN or iSCSI infrastrucutre is done company-wide, and might strongly influence the set of products that will support that decision. For example, those with a mix of mainframe and distributed servers looking for SAN-attached storage may look at an [IBM System Storage DS8000] and [TS3500 tape library] that can provide support for FICON and FCP.
Those looking at NAS or iSCSI might consider the IBM System Storage N series products, "unified storage" supporting iSCSI, FCP and NAS protocols. If you want the "wall-to-wall" to stretch across all the sites in your globally integrated enterprise, IBM's scalable NAS product, Scale-Out File Services[SoFS], provides a global name spacein combination with a clustered file system that provides incredible scalability and performance based on field-proven technology used by the majority of the [Top 100 supercomputer] deployments.
IBM can help you design an information infrastructure that fits either approach.
In preparation for my [upcoming trip to Australia and New Zealand], I decided to upgrade my smartphone. My service provider T-Mobile offered me the chance to try out any new phone for 14 days for only ten dollar re-stocking fee. For the past 16 months, I have used the Google G1 phone. This is based on a storage-optimized Android operating system, based on open source Linux, with applications processed in a storage-optimized virtual machine called Dalvik, based on open source Java. According to Wikipedia, Android-based phones have #1 market share [outselling both BlackBerry OS and Apple iOS phones]. There are over 70 different companies using Android, driven away from the proprietary interfaces from Apple, BlackBerry and Microsoft.
Since I was already familiar with the Android operating system, I chose the Samsung Galaxy S Vibrant. I liked my G1, but it had only a small amount of internal memory to store applications. The G1 supported an external Micro SDHC card, but this only was used for music and photos. There was no way to install applications on the memory card, so I found myself having to uninstall applications to make room for new ones. By contrast, the Vibrant has 16GB internal memory, plenty of room for all applications, and supports Micro SDHC up to 32GB in size. My model can pre-installed with a 2GB card, of which 1.4GB is consumed by James Cameron's full-length movie Avatar. On the G1, swapping out memory cards was relatively easy. On the Vibrant, you have to take the phone apart to swap out cards, so I won't be doing that very often. I will probably just get a 32GB card and leave it in there permanently.
(FTC disclosure: I work for IBM. IBM has working relationships with Oracle, Google, and lots of other companies. IBM offers its own commercial version of Java related tools. I own stock in IBM, Apple, Google. I have friends and family who work at Microsoft. My review below is based entirely on my own experience of my new Samsung Galaxy S Vibrant phone. Samsung has created different models for different service providers. The T-Mobile Vibrant is an external USB storage device with telephony capabilities, comparable to the AT&T Captivate, Verizon Fascinate, or Sprint Epic 4G. The majority of mobile phones in the world contain IBM technology. This post is not necessarily an endorsement for Samsung over other smartphone manufacturers, nor T-Mobile over other service providers. I provide this information in context of storage optimization, state-of-the-art for smartphones in general, and disputes related to software patents between companies. I hold 19 patents, most of which are software patents.)
When Oracle acquired Sun Microsystems, it inherited stewardship of Java. Java is offered in two flavors. Java Standard Edition (SE) for machines that are planted firmly on or below your desk, and Java Micro Edition (ME) for machines that are carried around. Most Java-based phones limit themselves to Java ME, but Google decided to base its smartphones on the more powerful Java SE, but then optimize for the limited storage and computing resources. These two levels of Java have radically different licensing terms and conditions, so Larry Ellison of Oracle cried foul. On The Register, Gavin Clarke has an excellent article with details of the Oracle-vs-Google complaint. Daniel Dilger opines that Oracle [might kill Google’s Android and software patents all at once]. Fellow blogger Mark Twomey (EMC) on his StorageZilla blog, argues that [it's not about Android phones, but Android everything].
My Vibrant is roughly the size of a half-inch stack of 3x5 index cards in my hand. In my humble opinion, the problem is the grey area between mobile phone and the desktop personal computer. Laptops, netbooks, iPads, tablet computers, eBook readers, and smartphones fall somewhere in between. At what point do you stop licensing Java SE and start licensing Java ME instead?
Let's take a look at all the stuff my new Samsung Vibrant can do, and let you decide for yourself. I have 140 applications installed, which I can access alphabetically. I also have up to seven screens which I can fill with application icons and widgets to simplify access. The screen measures about 4 inches diagonally. Click on each image below to see the full 480x800 resolution.
Each screen has five rows. On my first screen, I have the first two rows related to photography. This includes a camera, camcorder, bar-code scanner and visual search engine (Google Goggles). I am not happy with Flickr Droid app in uploading photos, so I might need to find another app for that. Other reviews I read complain that the Vibrant's camera does not have am LED flash for night time shots, and that there is no forward facing camera to do Skype or FaceTime-style videoconferencing. I think it is fine the way it is. An interesting feature of the camera app is that it uses the volume up/down buttons to zoom in and out.
The next two rows related to books and documents. In addition to both Amazon's Kindle and Barnes and Noble's Nook eBook readers, I have Dropbox to make it easy to transfer files between all my machines, a camera-scanner that generates PDFs, and ThinkFree, which appears to be based on OpenOffice open source software to create, view and edit WORD documents, EXCEL spreadsheets and PowerPoint presentations.
My second screen is for music and video entertainment.
The top row is consumed by a single widget for [Pandora], an internet radio station, not to be confused with the Pandora moon that the movie Avatar is based on. I-heart-radio, Slacker, and Last.fm are other internet radio stations. Be careful when roaming in another country, as the $15-per-MB transfer fees can really add up. While the Galaxy S has a built-in FM radio, T-Mobile has decided to disable this feature in its Vibrant model, in favor of internet-based radio stations.
I am glad the Samsung Vibrant uses the same 3.5mm combo audio jack that I mentioned in my blog post about my
[New ThinkPad T410]. This allows me to use the same headset for both my laptop and my cell phone.
For those who use Microsoft Windows Media Player v10 or above, this phone lets you transfer over your songs, playlists and videos via the USB cable in PMC mode. The TED application shows 18-minute videos of lectures at conferences that focus on Technology, Entertainment and Design. MobiTV offers live streaming of popular Television shows, normally ten dollars monthly, but I got a free 30-day trial in the deal.
Screen 3 is focused on travel. I have a 30-day free trial of GoGo, the new Wi-Fi networks on various airlines. Hopefully, I will get to try this out on my upcoming flights. When GoGo is not available, the Extended Controls widget allows me to turn the phone into "Airplane mode", which would allow me to read eBooks and listen to pre-recorded music and videos stored on my phone. Most of the apps on Android are free, but Extended Controls, shown here in the top row, cost me money but well worth it. With this you can customize different size widgets with all the appropriate setting toggles you want. On this one, I can toggle Wi-Fi, Data transfer, GPS positioning, and Airplane mode.
Google Maps, Google Places and Google Sky Map are all well represented here. I also like TripIt, which is a free Software-as-a-Service for managing your trip itenerary, and syncs up with their online website. Currency and Language translation can help on international travel. The standard Alarm Clock also includes Time Zone conversion as well.
My screen 4 is my central home page. There are four buttons on the bottom of the phone: Menu, Home, Back, and Search. Hit the "Home" button on any screen, and it jumps immediately to Screen 4. From here, I can get to any of the other screens with just swiping my finger across the surface. Therefore, I chose to keep this screen simple.
For meetings, I have a big clock, and an Extended Controls widget to set my phone on silent/vibrate mode, and show my battery status. I put icons here for apps that I might need in a hurry, like Camera, Evernote, or Shazam. For those not familiar with Shazam, it will listen to the microphone for whatever song is playing in the background where you are, and it will identify the song's title and artist.
The "Starred" folder lists those five or so contacts that I have marked with a "star" to be on this short list. From here, I can call or send them an SMS text message.
Screen 5 is for office productivity. I have a 2x2 widget from Astrid to list my to-do items. I have a 1x2 widget showing my last call. My calendar syncs up with my Google calendar online.
The Locale widget allows me to change which on-screen keyboard to use. There is the standard Android keyboard which allows voice-to-text input, the Samsung keyboard that offers [XT9 mode], and the new ["Swype"] keyboard that allows you to write words quickly with squiggles swiped across the keyboard. The Swype is incredible accurate when I am typing in English. When I am communicating in Spanish, it gets in the way, spell-checking when it shouldn't.
Screen 6 is for my social media, news and search facilities. I have HootSuite Lite for managing my Twitter and Facebook posts. For news junkies, NPR, USA Today and CNN all offer mobile versions.
I have a selection of browsers, including Opera Mini 5, and Dolphin Browser HD. The latter offers a variety of special add-ons similar to Firefox on a desktop system. I also have specialty search sites, including the Internet Movie Database (IMDB), Fandango for local movie times, and Dex for local phone listings.
Screen 7 is for system administration. The top row is another "Extended Controls" widget, this time to change between 2G and 3G networks, brightness setting, set the the time-out interval for when the screen should automatically shut off, and a "stay awake" to turn off the screen saver altogether.
I can do some really powerful things here. For example, I have an application to let me use secure shell (ssh) to access our systems at work. I also can "tether" my laptop to my Vibrant, for those few times when Wi-Fi is not available, to let my laptop use the phone's signal as a dial-up modem. It is slower than Wi-Fi, but might be just what I need in a pinch.
The bottom row is the same across all seven screens, which you can customize. I left the bottom row in its original default, with options to make phone calls, look up contacts, and send text messages. The bottom right corner launches a list of all applications alphabetically, to access those not on my seven main screens.
Just in case I switch to a local SIM card while abroad in another country, I asked T-mobile to unlock my phone, which they happily did at no additional charge. For example, while I am in Australia, I can either leave my T-Mobile USA chip in the phone, and pay roaming charges per minute, or I can purchase a SIM chip from a local phone company with pre-paid minutes. This often includes unlimited free incoming calls to a local Australian phone number, and voicemail.
Unlocking the phone to use different SIM cards is different than "jailbreaking", a term that refers to Apple's products. For Android phones, jailbreaking is called "rooting", as the process involves getting "root" user access that you normally don't have. The only reason I have found to have my phone "rooted" was to take these lovely screen shots, using the "Screen Shot It" application. This is another application that I paid for. I used the free trial for a few screenshots first to check it out, liked the results, and bought the application.
So, this new smartphone looks like a keeper. I got a screen protector to avoid scratching, and a two-piece case that snaps around the phone to give it more heft. All my chargers are "Mini USB" for my old G1 phone, and this new Vibrant phone is "Micro USB" instead, so I had to order new ones for my car, my office, and for my iGo (tip A97).
This review is more to focus on the fact that the IT industry is changing, and what was traditionally performed on personal computers are now being done on new handheld devices. Android provides a platform for innovation and healthy competition. Let's all hope Oracle and Google can work out their differences amicably.
Continuing this week's coverage of IBM's 3Q announcements, today it's all about storage for our mainframe clients.
IBM System Storage DS8700
IBM is the leader in high-end disk attached to mainframes, with the IBM DS8700 being our latest model in a long series of successful products in this space. Here are some key features:
Full Disk Encryption (FDE), which I mentioned in my post [Different Meanings of the word "Protect"]. FDE are special 15K RPM Fibre Channel drives that include their own encryption chip, so that IBM DS8700 can encrypt the data at rest without impacting performance of reads or writes. The encryption keys are managed by IBM Tivoli Key Lifecycle Manager (TKLM).
Easy Tier, which I covered in my post [DS8700 Easy Tier Sub Lun Automatic Migration] which offers what EMC promised but has yet to deliver, the ability to have CKD volumes and FBA LUNs to straddle the fence between Solid State Drives (SSD) and spinning disk. For example, a 54GB CKD volume could have 4GB on SSD and the remaining 50GB on spinning drives. The hottest extents are moved automatically to SSD, and the coldest moved down to spinning disk. To learn more about Easy Tier, watch my [7-minute video] on IBM [Virtual Briefing Center].
z/OS Distributed Data Backup (zDDB), announced this week, provides the ability for a program running on z/OS to backup data written by distributed operating systems like Windows or UNIX stored in FBA format. In the past, to backup FBA LUNs involved a program like IBM Tivoli Storage Manager client to read the data natively, send it over Ethernet LAN to a TSM Server, which could run on the mainframe and use mainframe resources. This feature eliminates the Ethernet traffic by allowing a z/OS program to read the FBA blocks through standard FICON channels, which can then be written to z/OS disk or tape resources. Here is the [Announcement Letter] for more details.
One program that takes advantage of this new zDDB feature already is Innovation's [FDRSOS], which I pronounce "fudder sauce". If you are an existing FDRSOS customer, now is a good time to get rid of any EMC or HDS disk and replace with the new IBM DS8700 system.
IBM System Storage TS7680 ProtecTIER Deduplication Gateway for System z
When it comes to virtual tape libraries that attach to mainframes, the two main players are IBM TS7700 series and Oracle StorageTek Virtual Storage Manager (VSM). However, mainframe clients with StorageTek equipment are growing frustrated over Oracle's lack of commitment for mainframe-attachable storage. To make matters worse, Oracle recently missed a key delivery date for their latest enterprise tape drive.
What's new this week is that IBM now supports native IP-based asynchronous replication of virtual tapes at distance, from one TS7680 to another TS7680. This replaces the method of replication using the back end disk features. The problem with using disk replication is that all the virtual tapes will be copied over. Instead, the ProtecTIER administrator can decide which subset of virtual tapes should be replicated to the remote site, and that can reduce both storage requirements as well as bandwidth costs. See the [Announcement Letter] for more details.
Wrapping up my series on a [Laptop for Grandma], I finally have something that I think meets all of my requirements! Special thanks to Guidomar and the rest of my readers who sent in suggestions!
I could have called this series "The Good, the Bad, and the Ugly". The [Cloud-oriented choices] weren't bad per se, but expected persistent Internet connection. The [Low-RAM choices] were not ugly per se, but had limited application options. The ones below were good, in that they helped me decide what would be just right for grandma.
Linux Mint 9
One of my readers, Guidomar, suggested Linux Mint Xfce. At LinuxFest Northwest 2012, Bryan Lunduke indicated that [Linux Mint] is the fastest growing Linux in popularity. You can watch his 43-minute presentation of [Why Linux Sucks!] on YouTube.
The latest version is Mint 14, but that has grown so big it has to be installed on a DVD, as it will no longer fit on a 700MB CD-ROM. Since I don't have a DVD drive on this Thinkpad R31, I dropped down to the latest Gnome edition that did fit on a LiveCD, which was Mint 9.
(In retrospect, I could have used the [PLoP Boot Manager CD], and installed the latest Linux Mint 14 from USB memory stick! My concern was that if a distribution didn't fit on a CD-ROM, it was expecting a more modern computer overall, and thus would probably require more than 384MB or RAM as well.)
Linux Mint is actually a variant of Ubuntu, which means that it can tap into the thousands of applications already available. Mint 9 is based on Ubuntu 10.04 LTS.
One of the nice features of Linux Mint is that there are versions with full [Codecs] installed. A codec is a coder/decoder software routine that can convert a digital data stream or signal, such as for audio or video data. Many formats are proprietary, so codecs are generally not open source, and often not included in most Linux distros. They can be installed manually by the Linux administrator. Windows and Mac OS are commercially sold and don't have this problem, as Microsoft and Apple take care of all the licensing issues behind the scenes.
The installation went smooth. It would have gladly set up a dual-boot with Windows for me, but instead I opted to wipe the disk clean and install fresh for each Linux distribution I tried.
Running it was a different matter. The screen would go black and crash. There just wasn't enough memory.
Since [Peppermint OS] was partially based on Lubuntu, I thought I would give [Lubuntu 12.04] a try. The difference is that Peppermint OS is based on Xfce (as is Xubuntu), but Lubuntu claims to have a smaller memory footprint using Lightweight X11 Desktop Environment (LXDE). This version claims to run in 384MB, which is what I have on grandma's Thinkpad R31.
There are two installers. The main installer requires more than 512MB to run, so I used the alternate text-based Installer-only CD, which needs only 192MB.
The LXDE GUI is simple and straightforward. As with Peppermint OS, I did have to install the Codec plugins. However, the time-to-first-note was less than two minutes, so we can count this as a success!
Linux Mint 12 LXDE edition
Circling back to Linux Mint, I realized that my problem up above was chosing the wrong edition. Apparently, Linux Mint comes in various editions, the main edition I had selected was based on Gnome which requires at least 512MB of RAM.
Other editions are based on KDE, xFCE and LXDE. Linux Mint 9 LXDE requires only 192MB of RAM, and the newer Linux Mint 12 LXDE requires only 256MB. I choose the latter, and the install went pretty much the same as Mint and Lubuntu above.
The music player that comes pre-installed is called [Exaile], which supports playlists, audio CDs, and a variety of other modern features, so no reason to install Rhythmbox or anything else. Grandma can even rip her existing audio CDs to import her music into MP3 format. Time-to-first-note was about two minutes.
The best part: the OS only takes up about 4GB of disk, leaving about 15GB for MP3 music files!
Lubuntu and Linux Mint LXDE were similar, but I decided to go with the latter because I like that they do not force version upgrades. This is a philosophical difference. Ubuntu likes to keep everyone on the latest supported releases, so will often remind you its time to upgrade. Linux Mint prefers to take an if-it-aint-broke-don't-fix-it approach that will be less on-going maintenance for me.
A few finishing touches to make the system complete:
A nice wallpaper from [InterfaceLift]. This website has high-res photography that are just stunning.
Power management with screen-saver settings to a nice pink background with white snowflakes falling.
A small collection of her MP3 music pre-loaded so that she would have something to listen to while she learns how to rip CDs and copy over the rest of her music.
Icons on the main desktop for Exaile, My Computer, Home Directory, and the Welcome Screen.
Larger Font size, to make it easier to read.
Update settings that only look for levels "1" and "2". There are five levels, but "1" and "2" are considered the safest, tested versions. Also, an update is only done if it does not involve installing or removing other packages. This should offer some added stability.
I considered installing [ClamAV] for anti-virus protection, but since this laptop will not be connected to the Internet, I decided not to burn up CPU cycles. I also considered installing [Team Viewer] which would allow me remote access to her system if anything should every fail. However, since she does not have Wi-Fi at home, and lives only a few minutes across town, I decided to leave this off.
Once again, I want to thank all of my readers for their suggestions! I learned quite a lot on this journey, and am glad that I have something that I am proud to present to grandma: boots quickly enough, simple to use, and does not require on-going maintenance!
