I have arrived safely to Istanbul, Turkey for the [Systems Technical University 2014] conference. The conference will feature experts from IBM Power Systems, IBM System x, IBM PureSystems, and IBM System Storage.
Here is the view from my hotel window. Up until the 19th century, this was open countryside. Around 1890, the Bomonti brothers from Switzerland set up a brewery, which was moved to this section of town in 1902, becoming the first Turkish brewery. In 1934, the brewery was nationalized and became the Istanbul Tekel Beer Factory. The Hilton Bomonti hotel where the conference is being held is named after these brothers.
Since this is my first time to Istanbul, and I did not have meetings until later in the afternoon for the conference, I decided to a bit of sightseeing.
(A special thanks to Gail Godbey of [Encounter Tours/Kaletours] who organized this entire tour of sightseeing for me on such short notice!)
The hippodrome was a stadium for horse and chariot racing, but now is just a square with a few obelisks. This one is the Thutmosis Obelisk from Egypt. The word hippodrome comes from the Greek hippos, meaning horse, and dromos, meaning path or way. Hippodromes were common features of Greek cities in the Hellenistic, Roman and Byzantine eras. My tour guide Erol Azor did a great job explaining everything.
My favorite stop of the day was the Blue Mosque, named after the blue tiles used on the dome. It is 43 meters high, making it one of the tallest mosques in the city. There are over 3,000 mosques here in Istanbul. In Turkish, this place is called Sultan Ahmet Camii after the Sultan Ahmet that had it built from 1609-1616. There are six minarets. The legend goes that the Sultan asked for a "gold" minaret, but the word for "gold" in Arabic sounds a lot the number six in Turkish, so that is why there are six of them.
Right next to the Blue Mosque is the Hagia Sofia, which was a Christian church first, then converted to a mosque, and now is a musuem. It was closed on Mondays, so all I could do was take pictures from the outside. Tulips are in full bloom throughout the city this month of April. If you notice, the minaret on the right is different color. Often, new sultans would add a minaret to an existing mosque, using whatever materials were available at the time. Kind of like adding a bedroom to an existing house.
Underneath the ground is the Basilica Cistern which held the drinking water for the city. The water came in on viaduct, and was kept underground. Today, it has a foot of water, and some fish, for people to admire the architecture employed.
Of course, no visit to Istanbul is complete without stopping at the Grand Bazaar. With over 4,000 tiny shops, it is a madhouse of gold and silver jewelry, blue jeans, leather goods, scarves, persian rugs, and antiques. Some places offered me free samples of Turkish delight, which are delicious cubes of flavored gelatin.
My day ended at the Topkapi palace. The word Topkapi is Turkish for "Cannon Gate", as this castle sits overlooking the peninsula and bosphorus strait that separates the Europe side from the Asian side of the city. Like the palace of Versaille in France, or Buckingham palace in England, the Topkapi palace was home to 36 sultans from 1299 to 1922.
You can spend hours here. There are beautiful gardens and various buildings surrounded by five kilometers of castle wall. Inside the buildings are displays of the family jewels, the clothes the sultans wore, their weapons, and religious relics.
It was good to get a flavor of the city, and a sense of the Turkish culture.
The first official day of the [Systems Technical University 2014] conference had keynote sessions in the morning. The conference features experts from IBM Power Systems, IBM System x, IBM PureSystems, and IBM System Storage.
The keynote sessions were started with Amy Purdy, IBM Director of Technical Training Services, the group that is running this conference.
This conference is not focused on System z solutions, as many of the System z clients were in New York City for this birthday event, but it came up several times during the keynote sessions.
(FTC Disclosure: I work for IBM, and this blog post may be considered a paid, celebrity endorsement of IBM products and services. IBM has business relationship with both Intel and Amazon mentioned during the course of the keynote sessions, but I have no financial stake in either company. I was the chief architect for DFSMS, the storage management component of the z/OS mainframe operating system, and was part of the team that ported Linux to the System z mainframe.)
Nicolas Sekkaki, IBM Vice President of Systems and Technology Group in Europe, discussed IBM's commitment to client's privacy, the x86 and POWER server platforms, and a variety of mind-bogging announcements. He is focused on three trends: Big Data, Cloud, and Mobile.
IBM is focusing its hardware efforts on high-value, high-margin solutions such as System Storage, POWER Systems and System zEnterprise mainframe environments. Did you know that 65 percent of the world's business transactions are processed by either POWER systems or System zEnterprise mainframe?
IBM is also extending its continued focus on Linux and Open Source initiatives. For the System zEnterprise mainframes, 78 percent of our clients run Linux on System z. Over 290 clients have added the "zBX" option that allows them to run Windows and AIX on the mainframe as well. It is now less expensive to run workloads on System zEnterprise -- about 1 dollar per day per server -- than public cloud offerings from Amazon Web Services. Linux on POWER also has lower Total Cost of Ownership (TCO) than Linux-x86.
Nicolas also mentioned major changes for the POWER Systems, starting with the [OpenPOWER Consortium], formed by IBM, Google, Mellanox, NVIDIA and Tyan.
The move makes POWER hardware and software available to open development for the first time as well as making POWER Intellectual Property licensable to others, greatly expanding the ecosystem of innovators on the platform. The consortium will offer open-source POWER firmware, the software that controls basic chip functions. By doing this, IBM and the consortium can offer unprecedented customization in creating new styles of server hardware for a variety of computing workloads.
IBM POWER has switched from being "Big Endian" to being "Bi-Endian", allowing operating systems to choose between "Big Endian" or "Little Endian" modes. The Big Endian mode allows for Linux compatibility with the System zEnterprise mainframe, and the Little Endian mode for compatibility with Linux-x86.
Thorston Kahrmann, Intel Account Director for EMEA, presented Intel's rich history of collaboration with IBM, from technologies like BlueTooth and PCiE Generation 3, to platforms like BladeCenter and NeXtScale, to Industry Standards.
IBM had a lot of "firsts" in the x86 server area, including the first 16-processor server, the first to offer hot-swap memory, and over 100 leading performance benchmarks.
The latest Intel Xeon chip is the E7 version 2. For example, changing from DB2 v10.1 on the old E7, to running DB2 BLU columnar acceleration on the new E7 version 2, resulted in a 148 times increase in performance. A query on a 10TB database that previously took four hours was completed in under 90 seconds.
Thorston also wanted to remind the audience that nearly every System Storage product from IBM, from the high-end XIV, SAN Volume Controller, SONAS and FlashSystem V840, to midrange and entry level Storwize products, are all based on Intel's x86 processors.
Louise covered the findings from the latest 2012 CEO study, gathering insight from 1709 CEO interviews. The major focus areas for CEOs are:
Empowering employees through company-wide values
Engaging customers as individuals, rather than via demographics
Amplifying innovation with strategic and tactical partnerships
With smartphones, tablets and ubiquitous Internet access, everyone is now a technologist, so that IT is now becoming a competitive differentiator. IT projects and Business projects are no longer separate. If your IT department is seen as an expense, it will continue to get its budget cut. If, however, your IT department is part of your revenue stream, then it can be viewed as an asset.
Sadly, over 75 percent of IT projects fail, either are way over budget, delivered late, or some combination of the two. Business leaders are pushing for IT improvements, but often CIOs are too afraid to take the risks to move the business forward. Louise cited three reasons for this, which she called the three C's:
The IT and Business leaders did not full understand the context of the project.
The content of the project was not properly defined between IT and Business architects.
The collaboration between IT and Business personnel was not properly established.
Louise wrapped up her session with asking a simple question: How much is the cost of a light bulb. Some might focus on the cost of the bulb itself, while others might add the cost of maintenance, having ladders and personnel to replace them as needed, and others might include the electricity consumed. Both Business and IT leaders need to focus on Total Cost of Ownership (TCO) in their planning.
I presented IBM's Smarter Storage Strategy. This is focused on three key areas:
Data-intensive Solutions. Storage is needed for Big Data analytics. IBM is focused on efficiency in all dimensions: capacity efficiency with data footprint reduction techniques, energy efficiency, administrator efficiency with ease-of-use interfaces, and reduced complexity.
Business-critical workloads. Storage needs to allow business to prioritize which applications and workloads are most critical, and automate Quality of Service (QoS) for each application based on its business importance. The result is a balance between performance and cost across the spectrum of applications.
Start quickly and add value. IBM is committed to support private, hybrid and public cloud deployments. Storage needs to support not just VMware, but also Hyper-V, KVM, PowerVM and z/VM. That is why IBM is a platinum sponsor for the OpenStack foundation.
Eric Aquaronne presented an excellent session on OpenStack foundation, an open source collaboration of various companies to bring a consistent Cloud-management standard across compute, storage and network resources.
Replication for Business Continuity and Disaster Recovery
I have been involved with Business Continuity and Disaster Recovery my entire 28-year career at IBM System Storage, so when I was asked to cover BC/DR in 75 minutes, I focused just on aspects related to disk-to-disk replication.
I divided the presentation into three sections:
Business priorities. You need to prioritize which business processes are most important, and prioritize your recovery accordingly.
Technical implementation. Once priorities are set, there are seven "Business Continuity Tiers" to choose from. BC Tier 1 is the least expensive, recovering from physical tapes stored in an off-site vault. The fastest recovery is BC Tier 7, which automates the storage, server and network fail-over to a secondary site in as little as 30 minutes.
Ongoing management. Just setting up a BC/DR implementation is not enough. It needs to be monitored to ensure that it continues to provide the protection you expect. BC/DR exercises should be performed one or more times per year to ensure that everyone has the skills and procedures documented to succeed in the event of a real disaster.
Of these seven BC tiers, BC Tier 6 is focused on storage replication, such as Metro or Global mirror available on our DS8000, XIV Storage System, SONAS and SAN Volume Controller. BC Tier 7 involves system automation, such as Tivoli Distributed Disaster Recovery Manager and GDPS.
What is Big Data? Architectures and Practical Use Cases
This session was an expanded version of the one I gave in Belgium last year. Big Data is a big topic, and there are a variety of "big data" related sessions at this conference. I focused on three key areas:
The change in the role of Storage Administrator. In the past, most of the data was structured and stored in databases, managed by database administrators. However, in today's environment, over 80 percent of the data is unstructured, outside of traditional relational databases, so either the database administrators need to learn new skills, or storage administrators will need to step up and help manage this unstructured data content.
The change in the role of Business Analyst. We are no longer just looking at the financial consequences of patterns and trends. The new role of Data Scientist needs to apply statistical models, show some business acumen, and be able to "tell a story" that is supported by the data when communicating findings to Business and IT leaders.
The change in the role of Decision Maker. In the past, Decision Support Systems were available only to the top-level business executives. Now, empowered employees have access to real-time analytics that can help them make decisions and take immediate actions.
This session packed the house, with standing room only. I would like to offer a special thanks to IBM VP Bob Sutor, Stephen Brodsky, Linton Ward, and Ralph McMullen in helping me finalize my presentation.
Continuing coverage of the [Systems Technical University 2014] conference, we had an early morning awards ceremony to celebrate top sellers that led big wins in Europe for FlashSystems, XIV, Power Systems, and PureSystems.
Afterwards, there were several breakout sessions on day 2.
Storage Technology Futures -- fresh from IBM research labs, tomorrow in your datacenter
Axel Koester presented several projects from IBM Research labs that have contributed to actual products, including the incredible scalability of [PERCS] that was incorporated into IBM General Parallel File System (GPFS).
Cloud Storage and Active Cloud Engine
My presentation started off explaining the taxonomy of cloud storage. There are basically four kinds of cloud storage: persistent storage, ephemeral storage, hosted storage, and reference storage. Each of these has unique access patterns and service level requirements.
IBM has three distinct cloud storage offerings, so I covered IBM XIV Storage Systems, SONAS and Storwize V7000 Unified with Active Cloud Engine, and Linear Tape File System (LTFS) Enterprise Edition (LTFS-EE).
FlashSystem competitive overview
Henrik Wilken provided an excellent presentation comparing IBM FlashSystems to the dozen or more competitors that offer all-flash or hybrid flash-and-disk combinations.
IBM Tivoli Storage Productivity Center
From 2001 to 2003, I was the chief architect for what is now called Tivoli Storage Productivity Center. It continues to be the top most requested topic for briefings at the IBM Tucson Executive Briefing Center.
I presented an overview of Tivoli Storage Productivity Center, with a brief update on what's new in TPC 5.2.1 and the SmartCloud Virtual Storage Center v5.2.1 releases.
IBM Archive Storage Solutions - Data Retention for Government Compliance and Industry Regulations
I can't believe it has been nine years since I was on the Product Development Team for the IBM DR550 Data Retention storage solution!
In this session, I explained the lessons we learned from the DR550, its successor the Information Archive, and how we now position System Storage Archive Manager (SSAM) software as their replacement. SSAM was recently certified by KPMG to meet a variety of US, European and International laws.
Step Right Up! Take your presentation skills to the next level
Glenn Anderson presented this session under the guise of "Professional Development". Whether you are new to public speaking and looking for some guidance, or are an experienced A-list celebrity looking to gain a few pointers, this session covered it all.
Some of my favorites:
Presentations are not Documentation! If a presentation had all the information to stand on its own, nobody would even bother to listen to the speaker. Many new presenters have 3-4 lines for titles, and too many words in small font to ensure they cover all the details to speak on. Don't do it. My rule of thumb is that 50 percent of the information is conveyed verbally, and the other 50 percent visually from the presentation.
Simplicity is the ultimate sophistication. I couldn't agree more. I try to focus on my core message in my presetations. I am a big fan of the [KISS principle] which stands for "Keep it simple, stupid!"
VOICE - Victory over inconsistent conscious energy! There is nothing more painful than hearing a public speaker who talks to softly, too loudly, or in a monotone manner. Mix it up! If you want to capture someone's attention, whisper! Vary your volume for effect.
Presenting is like Pouring Wine. At cocktail parties, the hosts will walk around with the bottle, and refill the glasses of those who are actively drinking the wine, but leave alone those who haven't sipped a drop. Public speakers need to focus on the needs of those in the audience paying close attention, and ignore people who are asleep, paying attention to their laptops and smartphones, or otherwise distracted.
Don't memorize - Extemporize. Too often, new speakers try to memorize their entire presentation. This doesn't go well, and can end up looking like an actor on live stage forgetting his next line. Instead, focus on getting the general idea across in a more natural conversational tone.
Building Open Clouds on POWER Systems
Mandie Quartly presented the excitement of building a cloud using IBM's new Linux-only line of PowerLinux™ servers, KVM, virsh, virtio and OpenStack interfaces. Jeff Scheel was on hand to interject bits of wisdom throughout her session.
IBM is investing heavily into the Linux side of all of its servers, and the latest investments have been focused on the POWER systems.
Storage Clouds in the Big Blue Sky
Dick Vogelsang presented this session focused mostly on the "Self-service" aspect of Cloud Storage. While this sounded like it would be similar to my session from yesterday, it was actually quite different.
Vogelsang explained SmartCloud Storage Access, and compared this to how competitors are providing (or not providing) self-service provisioning of file spaces and LUNs. He gave examples based on VMware, Hyper-V, and OpenStack Foundation.
It is interesting the angle or spin that each speaker gave to each topic!
Johann Weiss, Jim Blue and I joined several other local experts to answer questions and respond to comments and suggestions attendees had about IBM System Storage products and solutions. Here is a sample:
I would like to add 1TB of Flash to our FlashSystem 810 and have the system automatically re-stripe across this new capacity non-disruptively?
How can I have XIV systems at two datacenters in an active/active configuration that would allow me to vMotion from one location to the other non-disruptively?
Put them behind the SAN Volume Controller in Stretched Cluster mode.
What about a similar active/active but for NAS?
IBM N series.
I would like HyperSwap on the SVC/Storwize family like the DS8000 offers for AIX?
When will IBM offer a multi-frame XIV?
The "Hyper-Scale" set of features lets you logically connect 144 XIV frames together and treat as a single system. There is no need to physically bolt them together, since the communication is done over standard network switches.
When will IBM devices have native FCoE support?
All IBM System Storage products work within an FCoE framework today, either with native FCoE support, or through Top-of-Rack switches splitting out the traffic between IP and FCP traditional networks. IBM Storwize and N series products support FCoE natively, and any disk behind virtualized by SAN Volume Controller or Storwize can be access via FCoE hosts because of this support.
What is FLAPE?
FLAPE is the combination of Flash and Tape. Both of these technologies are improving over 40 percent year-to-year, but disk is slowing down to 20 percent improvement. It is possible to combine Flash and tape systems, such as IBM LTFS-EE or IBM ProtecTIER TS7600 series.
Only the Storwize V7000 Unified supports file modules to add NAS capabilities, what can IBM offer us that is smaller for NAS deployments, perhaps a Storwize V5000 Unified or Storwize V3700 Unified?
Consider the IBM N3000 series.
Other storage vendors indicate that RAID-5 and RAID-6 are running out of steam, are no longer practical to protect ever growing capacities of disk. What is IBM planning in this area?
IBM XIV Storage System was one of the first to offer a distributed RAID that addresses many of the RAID-5/RAID-6 drive rebuild concerns. IBM DCS3700 and DCS3860 also have Dynamic Disk Pooling to reduce drive rebuild impact. Lastly, IBM GPFS now offers Native RAID support, used in the IBM GPFS Storage Server.
Is it true that GPFS is NFS only?
Do not confuse GPFS the file system with the various storage offerings that are based on GPFS. IBM SONAS and Storwize V7000 Unified, both based on GPFS, support CIFS, NFS, HTTPS, SCP and FTP. IBM GPFS Storage Server can be configured to access GPFS natively, or you can run NFS v3/v4 server to make those protocols available. With Microsoft [Windows Storage Server], you can provide CIFS access to any GPFS-based storage solution.
LTFS-EE sounds like an exciting alternative to IBM Tivoli Storage Manager HSM space management for moving data from disk to tape. Do you agree?
Yes, we agree. However, TSM HSM space management supports a broader set of file systems. LTFS-EE only provides disk-to-tape movement for IBM GPFS.
Why does the DS8000 implementation of Easy Tier sub-LUN automated tiering support three tiers, but SVC/Storwize only support two tiers?
The same software engineering team works on both, but develop new features for the DS8000 first, get it working, then port it over to the Storwize family. At times, there might be gaps between what is supported on the latest DS8000 version and what is available on Storwize family products.
In an SVC Stretched Cluster, I would like to have the third quorum disk connected over the IP network, rather than FCP.
Personally, I enjoy these interchanges. They are sometimes called "Birds-of-a-Feather" or BOF at some conferences, "Free-for-All" at others. At IBM conferences, they are often titled "Meet the Experts". Whatever you call it, the questions and feedback on what clients are thinking are quite useful for product planning and prioritization of future planned features.
New Generation Storage Tiering: Less Management, Lower Investment and Increased Performance
This was not just an update to my session last year in Brussels, Belgium. Rather, I decided to start over and focus I/O density as the metric to focus my efforts, armed with real data from Intelligent Storage Tiering Analysis (ISTA) studies done at various clients. From that, I was able to talk about storage tiering on three fronts:
Storage tiering between Flash and disk. IBM FlashSystem and IBM Easy Tier on DS8000 and Storwize family for hybrid Flash-and-disk configurations.
Storage tiering between disk and tape. HSM and Information Lifecycle Management (ILM) on SONAS, Storwize V7000 Unified and LTFS-EE.
Storage tiering automation across your entire environment. ISTA studies can help identify a target mix of Tier 0, Tier 1, Tier 2 and Tier 3 storage. SmartCloud Virtual Storage Center can recommend or perform the movement of LUNs to more appropriate tiers, based on age and I/O density measurements.
Next Generation FlashSystem 840 and V840, Architecture Deep Dive
Detlef Helmbrecht, from the IBM Advanced Technical Skills team in Germany, presented this deep dive in our latest IBM FlashSystem offerings. He started with an analogy. Latency is like a single car driving down an empty highway. IOPS, on the other hand, is like a lot of cars stuck in slow traffic, with all lanes filled on the autobahn. While there are more cars transported on a full highway, the individual cars are not driving very fast. Flash versus disk has similar comparisons.
Detlef explained the differences between the previous FlashSystem 810/820 with the new 840, as well as talk about the FlashAdapter 90 now available as a PCIe card.
Finally, we talked about SAN Volume Controller combined with Flash, and the new FlashSystem V840 which combines SVC and FlashSystem 840 to have an incredibly function-rich, robust solution.
Data Footprint Reduction - Understanding IBM Storage Efficiency Options
My last session of the week! This session covered all of the various technologies for data footprint reduction, including Thin Provisioning, Space-efficient FlashCopy and snapshots, Real-time compression and data deduplication. Frankly, I wasn't expecting many people to attend the last session of the last day, but nearly 50% of the seats were filled, so I was quite pleased on the turn-out.
Fun Fact: Istanbul is considered by TripAdvisor in 2014 as the #1 most popular city to visit in Europe!
Before dinner, I was able to catch up with my colleagues from across the pond. Here I am pictured with Ola Surowiec, a Power Systems sales specialist from Scotland.
The dinner was set up as self-service buffet style, with choices of European, Asian, and Middle Eastern cuisine. This is largely the heritage of the Ottoman empire to provide a fusion of flavors from its neighbors.
The city of Istanbul is considered the border between Europe and Asia, with one side of the city on the "European" side, and the other side of the Bosphorus strait being the "Asian" side.
With a population of over 14 million, Istanbul forms one of the largest urban agglomerations in Europe, second largest in the Middle East and the third-largest city in the world by population within its city limits.
The entertainment started with two [belly dancers], one male and one female. (IBM is an equal opportunity employer!) For those not familiar with this particular form of performance art, it is improvised folk dances based on torso articulation and abdominal movements.
I have seen dancers before in Egypt, the country that most people associate with the origin of belly dancing, but the Turkish version is considered more energetic and athletic. Certainly both of our dancers were quite flexible.
This was followed by a live cover band that played the latest English-language hits. Several Americans at the table asked "Wait? We come all the way to Turkey and the local band sings the songs in English?"
In the corner, attendees were invited to dress up as their favorite sultan to take photograph. Here for example, are some of the members of the STU event team. Mo McCullough, Don Meyer, Marlin Maddy, Glenn Anderson and Alex Abderrazag pose with two lovely local ladies in full costume.
The word "sultan" derives from the Arabic word meaning "strength", "authority" or "power". Sultans ruled the Turkish empire from 1299 to 1922.
The [Topkapi palace], where I visited earlier in the week, contains clothing on display of the sultans and princes from the second half of the 15th century to the early 20th century.
Well, it's Tuesday again, and you know what that means? IBM announcements!
Today's announcements are all about the Storwize family, IBM's market-leading Software Defined Storage offerings. Having sold over 55,000 systems, and managing over 1.6 Exabytes of data, IBM continues to be the #1 leader in storage virtualization solutions. The Storwize family consists of the SAN Volume Controller (SVC), Storwize V7000, Storwize V7000 Unified, Flex System V7000, Storwize V5000, Storwize V3700 and V3500.
SAN Volume Controller 2145-DH8
The new 2145-DH8 model is a complete repackaging of this popular storage system. The previous model, the 2145-CG8, was 1U-high x86 server per node, and each node required a separate 1U-high UPS to provide battery protection for its cache. Nobody liked this. The new 2145-DH8 instead is a 2U-high node with two hot-swappable batteries, eliminating the need for UPS altogether. Thus, an SVC node-pair using the 2145-DH8 models takes up the same 4U space, but with fewer cables. The SVC can now also support standard office 110/240 voltage sources.
The new model sports an 8-core processor with 32GB RAM. Since these are 2-socket servers, IBM offers that option to add a second 8-core processor and additional 32GB RAM to help boost Real-time Compression. Each node can have optionally one or two hardware-assisted compression cards which use the Intel QuickAssist chip to boost compression performance.
While the Real-time Compression was in fact, real-time, performed in-line to the read/write I/O process, at latency comparable to uncompressed data for applications, the compression process on older models was entirely software-based, consuming some of the CPU resources, which lowered the maximum IOPS of the solution. With the added cores, added RAM, and hardware-assisted compression chips, IBM resolves that concern. In fact, the new 2145-DH8 with compression can provide more IOPS than an older 2145-CG8 without compression.
The previous model 2145-CG8 allowed you to put up to 4 small SSD drives in the node itself, which were treated the same as externally Flash drives for purposes of having a high-speed storage pool for select volumes, or automated sub-LUN tiering with Easy Tier. The new model 2145-DH8 allows you to attach up to 48 Solid State Drives (SSD) via 12Gb SAS cables. These are housed in the new 2U-high 24F enclosures that can offer up to 38.4 TB of Flash per SVC I/O group.
IBM also re-designed the host/device ports to use Hardware Interface Card (HIC) slots. In the 2145-CG8, you had four FCP ports, two 1GbE Ethernet ports, with options to add two 10GbE Ethernet ports or four additional FCP ports. If you had mostly an FCoE or iSCSI environment, you didn't need the FCP, and if you were mostly a FCP Storage Area Network (SAN) environment, then most of the Ethernet ports went unused. To solve this, the 2145-DH8 can allow you to have up to six HIC cards that are either FCP, Ethernet, or SAS. There are three 1GbE fixed Ethernet ports which can be used for iSCSI and administration.
If you have SVC today, you can upgrade non-disruptively by either swapping out your current SVC engines with the new 2145-DH8 engines, or you can add the new 2145-DH8 engines to your existing SVC cluster. Either way, there is no outage to your applications!
This is the next generation of the popular Storwize V7000. The previous generation had a 4-core processor and 8GB RAM per canister. The new model has an 8-core processor with 32GB of RAM per canister, with the option to double these to boost Real-time compression. There are two canisters per control enclosure, which gives you 64GB to 128GB of RAM per Storwize V7000 I/O group.
The new Storwize V7000 comes with one hardware-assisted compression chip on the mother board of each canister, with the option to add a second chip per canister.
Each canister offers three HIC slots, which can be used for the additional hardware-assist compression chip, FCP or Ethernet ports.
To accommodate these HIC slots, new canisters were needed. Instead of the flat wide style top and bottom, we now have taller, thinner canisters that sit side to side. This side-to-side design is similar to our existing Storwize V5000 and V3700 models.
The previous model could support up to 9 expansion enclosures per control enclosure. The Storwize V7000 can have up to 24 drives in its control enclosure, and now attach up to 20 expansion enclosures, which allows up to 504 drives per control enclosure, and up to a maximum of 1,056 drives per Storwize cluster.
If you have previous models of Storwize V7000, you can add the new Storwize V7000 into the same cluster, or virtualize the previous storage for migration purposes.
The new software applies new capabilities to both new generation hardware as well as the older models, so people with existing gear can benefit as well.
In prior releases, the sub-LUN automated tiering was limited to two levels: Flash and HDD. This lumped all 15K, 10K and 7200 RPM drives into a common HDD category. In the new v7.3.0 code, you can now have three levels: Flash, Enterprise HDD, and Nearline HDD, or two HDD levels: Enterprise and Nearline. The Enterprise level combines 15K and 10K RPM drives, similar to what is done on the IBM System Storage DS8000 disk systems.
The new code is also able balance your storage pools, and can be used with uniform or mixed storage pools to eliminate performance hot spots.
The new code has been enhanced to detect the hardware-assisted compression chip on the new SVC and Storwize V7000 models, and use those if available.
For the Storwize V3700 and V5000 models, the new code allows up to nine expansion enclosures per control enclosure. In the previous models, the V3700 allowed only four expansions, and the V6000 only six expansions per control enclosure. The V3700 can now support up to 240 drives, and the V5000 can support up to 480 drives.
IBM Storwize V7000 Unified File Module software v1.5
For Storwize V7000 Unified clients, there is new software for the File Modules that provide NFS, CIFS, FTP, HTTPS and SCP protocol capability. The new v1.5 code now adds NFS v4 and SMB 2.1 levels of support. Most NFS users are still on NFSv3, but about 20 percent of NFS users are using NFS v4 which offers stateful access. The SMB 2.1 for CIFS was introduced by Microsoft in Windows 7 and Windows Server 2008 R2.
Deterministic ID mapping allows you to map Windows userids to UNIX/Linux group and owner id numbers. In the past, the problem is that this mapping is different on each machine, so people often had to stand up a Windows System for Unix Services (SFU) server to provide consistent ID mapping. Now, with v1.5 code, you will no longer have to do this. The deterministic ID mapping will can now replicate the mapping to each machine without an SFU server.
Active Cloud Engine allows up to ten Storwize V7000 Unified to be connected across distance to form a single global name space. WAN caching, however, was restricted to a single site having write capabilities, while the others were read-only. In v1.5 release, IBM now supports multiple independent writers at different locations on the same fileset.
Security enhancements include multi-tenancy, configurable password policies, session policies, and hardened boot and SSH configurations. With NFS v3/v4, you can now use [Kerberos] for security.
Finally, I am please to see that we now have Cinder support for files on the Storwize V7000 Unified on the OpenStack Havana release that just came out last month. The OpenStack Cinder interface can assign LUNs to virtual machines, but the new Havana release allows NAS systems to dole out files that act as LUNs, such as OVA or VMDK files. The advantage is that these files can managed by Active Cloud Engine, cached locally across global name space, have policies place them on appropriate storage tiers, and inactive Virtual Machine images can be migrated to less expensive disk or tape.
Marking the occasion, here is an important letter from our Vice President, Laura Guio:

To Whom it may concern
Subject: ProtecTIER Development Update:
This year marks the sixth anniversary of IBM's acquisition of Diligent Technology. Over the past six years IBM has emerged as a leader in enterprise class data deduplication. Our highly scalable, dual node hardware redundancy and gateway design are unique characteristics in the industry. IBM fundamentally believes in the importance of cost saving data deduplication technology and continues to enhance our solution, improve value and increase investment protection for our installed base.
First, it is important to note what IBM has done most recently. IBM is among the first to integrate flash technology along with deduplication to boost performance and lower cost. Integration of the IBM FlashSystem 840 for metadata was completed the day the system was publically announced. The speed of technology integration is a result of our flexible gateway design which simplifies technology adoption. It also is enabled by our global development team providing a 24x7 system design, product test and integration environment.
Secondly, IBM has recently released ProtecTIER Mainframe Edition which enables the same enterprise class deduplication capability now for IBM System z. Another distinctive feature of ProtecTIER is its ability to sustain high throughput for both read and write operations. Most deduplication methodologies have an inherent read performance penalty. Since mainframe tape operations are much more read intensive than distributed systems, we were one of the first to market with a practical deduplication offering for all mainframe tape applications.
That's just what we've done getting out of the starting blocks in 2014. Our development team continues to enhance ProtecTIER. We're also working on refreshing the entire ProtecTIER product line with new model enhancements. A new gateway design is underway which will improve performance of the existing DD5. We expect this to be available as an upgrade, providing investment protection for existing ProtecTIER clients. The SM2 product family is also being redesigned to extend its capacity range. Along with hardware changes, we will widen the disk support matrix offering enhanced flexibility and new levels of price performance.*1*
We expect 2014 to be a busy year for IBM deduplication. We have development facilities around the world in Europe, North America, Central America and Asia, working on ProtecTIER. IBM continues to market, sell, and support ProtecTIER as our strategic offering for cost-reducing deduplication technology. Any suggestion that ProtecTIER is fading away is wishful thinking by our competitors. We are working to expand our markets as we have demonstrated by our recent introduction of ProtecTIER into the mainframe. Furthermore, we are looking to expand the use cases for ProtecTIER, which can now be attached as a NAS file system, to other areas besides pure backup. We're excited about what we are delivering today and where we can provide leadership by leveraging deduplication for customer storage environments.
