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.
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.
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!
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.
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!
