Well, it's Tuesday, which means IBM makes its announcements!
This week, IBM announces that it now supports 50GB Solid State Disk (SSD) in its [IBM System Storage EXP3000] disk systems.IBM has already made announcements about SSD enablement in the DS8000 and SAN Volume Controller (SVC), but now the EXP3000 brings SSD technology down to smaller System x server deployments.
Adoption of this new exciting technology is still in the early stages, despite the fact that IBM and other vendors have been touting this technology for a while. (For a quick blast to the past, here was my first post on the subject back from December 20, 2006: [Hybrid, Solid State and the future of RAID])Recently, fellow blogger BarryB admitted that EMC have only sold SSD to [hundreds of their customers], and to be fair, I suspect IBM's sales of SSD in its BladeCenter servers [available since July 2007] have been in similar single-digit percentage territory as well.
The advantage of today's announcement is that you can mix and match SSD drives with SAS and SATA drives in the EXP3000. You won't have to buy the entire drawer of SSD, you can start with just a few, depending on your business needs. On the other extreme, you can have up to two drawers, with 12 SSD drives each, for a total of 24 drives directly attached to System x servers via the ServeRAID MR10M SAS/SATA controller adapter.
Well it's Tuesday again, and you know what that means.. IBM announcements! Today, IBM announces that next Monday marks the 60th anniversary of first commercial digital tape storage system! I am on the East coast this week visiting clients, but plan to be back in Tucson in time for the cake and fireworks next Monday.
1925 - masking tape (which 3M sold under its newly announced Scotch® brand)
1930 - clear cellulose-based tape (today, when people say Scotch tape, they usually are referring to the cellulose version)
1935 - Allgemeine Elektrizitatsgesellschaft (AEG) presents Magnetophon K1, audio recording on analog tape
1942 - Duct tape
1947 - Bing Crosby adopts audio recording for his radio program. This eliminated him doing the same program live twice per day, perhaps the first example of using technology for "deduplication".
According to the IBM Archives the [IBM 726 tape drive was formally announced May 21, 1952]. It was the size of a refrigerator, and the tape reel was the size of a large pizza. The next time you pull a frozen pizza from your fridge, you can remember this month's celebration!
When I first joined IBM in 1986, there were three kinds of IBM tape. The round reel called 3420, and the square cartridge called 3480, and the tubes that contained a wide swath of tape stored in honeycomb shelves called the [IBM 3850 Mass Storage System].
My first job at IBM was to work on DFHSM, which was specifically started in 1977 to manage the IBM 3850, and later renamed to the DFSMShsm component of the DFSMS element of the z/OS operating system. This software was instrumental in keeping disk and tape at high 80-95 percent utilization rates on mainframe servers.
While visiting a client in Detroit, the client loved their StorageTek tape automation silo, but didn't care for the StorageTek drives inside were incompatible with IBM formats. They wanted to put IBM drives into the StorageTek silos. I agreed it was a good idea, and brought this back to the attention of development. In a contentious meeting with management and engineers, I presented this feedback from the client.
Everyone in the room said IBM couldn't do that. I asked "Why not?" The software engineers I spoke to already said they could support it. With StorageTek at the brink of Chapter 11 bankruptcy, I argued that IBM drives in their tape automation would ease the transition of our mainframe customers to an all-IBM environment.
Was the reason related to business/legal concerns, or was their a hardware issue? It turned out to be a little of both. On the business side, IBM had to agree to work with StorageTek on service and support to its mutual clients in mixed environments. On the technical side, the drive had to be tilted 12 degrees to line up with the robotic hand. A few years later, the IBM silo-compatible 3592 drive was commercially available.
Rather than put StorageTek completely out of business, it had the opposite effect. Now that IBM drives can be put in StorageTek libraries, everyone wanted one, basically bringing StorageTek back to life. This forced IBM to offer its own tape automation libraries.
In 1993, I filed my first patent. It was for the RECYCLE function in DFHSM to consolidate valid data from partial tapes to fresh new tapes. Before my patent, the RECYCLE function selected tapes alphabetically, by volume serial (VOLSER). My patent evaluated all tapes based on how full they were, and sorted them least-full to most-full, to maximize the return of cartridges.
Different tape cartridges can hold different amounts of data, especially with different formats on the same media type, with or without compression, so calculating the percentage full turned out to be a tricky algorithm that continues to be used in mainframe environments today.
The patent was popular for cross-licensing, and IBM has since filed additional patents for this invention in other countries to further increase its license revenue for intellectual property.
In 1997, IBM launched the IBM 3494 Virtual Tape Server (VTS), the first virtual tape storage device, blending disk and tape to optimal effect. This was based off the IBM 3850 Mass Storage Systems, which was the first virtual disk system, that used 3380 disk and tape to emulate the older 3350 disk systems.
In the VTS, tape volume images would be emulated as files on a disk system, then later moved to physical tape. We would call the disk the "Tape Volume Cache", and use caching algorithms to decide how long to keep data in cache, versus destage to tape. However, there were only a few tape drives, and sometimes when the VTS was busy, there were no tape drives available to destage the older images, and the cache would fill up.
I had already solved this problem in DFHSM, with a function called pre-migration. The idea was to pre-emptively copy data to tape, but leave it also on disk, so that when it needed to be destaged, all we had to do was delete the disk copy and activate the tape copy. We patented using this idea for the VTS, and it is still used in the successor models of IBM Sysem Storage TS7740 virtual tape libraries today.
Today, tape continues to be the least expensive storage medium, about 15 to 25 times less expensive, dollar-per-GB, than disk technologies. A dollar of today's LTO-5 tape can hold 22 days worth of MP3 music at 192 Kbps recording. A full TS1140 tape cartridge can hold 2 million copies of the book "War and Peace".
(If you have not read the book, Woody Allen took a speed reading course and read the entire novel in just 20 minutes. He summed up the novel in three words: "It involves Russia." By comparison, in the same 20 minutes, at 650MB/sec, the TS1140 drive can read this novel over and over 390,000 times.)
If you have your own "war stories" about tape, I would love to hear them, please consider posting a comment below.
We have a new member of the ever-growing IBM Spectrum Storage family! IBM Spectrum Discover is modern metadata management software that delivers data insight for petabyte-scale, unstructured data.
IBM Spectrum Discover easily connects to IBM Cloud Object Storage (COS) and IBM Spectrum Scale and Elastic Storage Server (ESS) to rapidly ingest, consolidate, and index metadata for billions of files and objects, providing a rich layer of metadata on top of these storage sources. IBM plans to extend support to other platforms next year.
This metadata enables data scientists, storage administrators, and data stewards to efficiently manage, classify, and gain insights from massive amounts of unstructured data. The insights gained accelerate large-scale analytics, improve storage economics, and help with governance to create competitive advantage, speed critical research, and mitigate risk.
This initial release is labeled v2.0 as IBM has deployed this in beta form already at various client locations. Here are some key highlights:
Event-notifications and policy-based workflows to automate metadata ingestion and metadata indexing at a petabyte scale
Fine-grained views of storage consumption based on a wide range of system and custom metadata
Fast, efficient search through petabytes of data, resulting in highly relevant results for large-scale analytics
Ability to quickly differentiate mission-critical business data from data that can either be deleted or moved to a cheaper, colder tier
Policy-based custom tagging that enables organizations to classify and categorize data, and align this data with the needs of the business
A software developers kit (SDK) to build action agents that extract metadata from file headers and content, automate data movement, and provide integration to open source software, such as Apache Spark, Apache Tika, PyTorch, Caffe and TensorFlow, to facilitate data identification and speed large-scale data processing
The latest IBM FlashSystem 900 comes in two models, the AE3 "full purchase" model, and the UF3 "storage utility pricing" model where you pay less initially, and then more as you consume more of the capacity. They are the same hardware, just licensed differently.
Currently, IBM offers FCP or InfiniBand host attachment, with up to twelve 3.6TB, 8.5TB or 18TB modules (PCiE card). A full 2U drawer would be configured as 10+P+S RAID5 for high availability and data protection.
Each module offers embedded compression chip, but modules only had enough DRAM cache to allow a maximum of compressed 22TB effective data, so while the 3.6TB and 8.5TB could compress data up to 2.5x, the 18TB card was somewhat limited at 1.2x, which might be fine for some already-compressed data like MP3 audio, or JPEG photos.
This month, IBM offers new XL MicroLatency Modules, 18TB cards with enough DRAM cache to support 44TB compressed data, up to an effective 2.4x compression ratio. A full twelve-module drawer could hold up to 440TB of effective capacity.
IBM also now offers a quad-port 16Gb FCP card that supports both SCSI and NVMe commands over fabric. This is often denoted as either FC-NVMe or NVMe/FC. The FlashSystem 900 already supported NVMe-OF for InfiniBand (see my blog post [IBM February 2018 Announcements])
IBM Cloud Tape Connector for z/OS is a software-defined storage solution that provides an alternative to virtual tape libraries like the TS7760. Here are some highlights:
Robust virtual tape emulation solution with e-vaulting to cloud-based offsite storage for cold, archival, or backup data. Virtual tape emulation simulates IBM compatible tape controllers, tape drives, and tape volumes, maintained on any IBM z/OS-compatible disk system, such as IBM DS8000. IBM Cloud Tape Connector for z/OS provides several vault, transfer, and recovery options to support business continuity and resiliency.
Sequential z/OS data set cloud storage and retrieval. Sequential data sets stored on disk or flash storage can be moved to the cloud by IBM Cloud Tape Connector for z/OS without the requirement of performing a tape-write operation.
Automatic application recall of data from cloud, whether e-vaulted through virtual tape emulation or copied directly to the cloud.
Pervasive encryption support. This feature enables enterprises to ensure that any data copied to the cloud is encrypted before it is transmitted, automatically protecting and handling the encryption keys.
Support for IBM Cloud Object Storage using S3 protocol, as well as Amazon S3, Hitachi HCP protocol, and EMC Elastic Cloud Service Protocol.
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.
When IBM designed the DS8870, it changed the bulk power supplies and batteries used in the previous DS8800 model to highly energy-efficient [DC-UPS]. In addition to reducing the overall energy consumption of the DS8870, it also gave the engineers space above the units to put 4U of standard 19-inch rack equipment.
The High Performance Flash Enclosure provides an ultra-dense and ultra-high-performance option. Each HPFE can delivers up to 250,000 IOPS and up to 3.4 GB/s bandwidth.
Up to thirty 387 GB Enterprise Multi-Level Cell (eMLC) flash cards provide up to 11.6 TB of raw capacity, about 9.2 TB usable, in only 1U of 19-inch rack space. A pair of very powerful integrated SAS RAID engines manage RAID-5 across the flash cards. The HPFE attaches directly to GX++ slots in the two DS8870 POWER7+ controllers, rather than using the Device Adapter (DA) loops.
You can have up to four of these HPFE in the "A" frame of your DS8870. Each HPFE can have either 16 or 30 flash cards. For 16 cards, you would have two spare plus two 6+P RAID-5 ranks. For 30 cards, you would add another two 6+P RAID-5 ranks.
Easy Tier Enhancements
Easy Tier is IBM's market-leading sub-volume automated tiering inside the DS8870 disk system. There were several enhancements in this announcement.
The first enhancement is to "Easy Tier Server", a feature that coordinates caching of active blocks of data inside the server's own internal Flash. This had supported Power Systems with EXP30 Ultra drawers, and now expanded to support IBM [Flash Adapter 90].
The second enhancement is to the three-level (Flash,Enterprise,Nearline) tiering algorithm. Inside the DS8870, the new HPFE flash cards will be part of the "Flash Tier" along with solid state drives (SSD) attached to the DA loops. Internal inter-tier load-balancing will take into account the faster nature of the flash cards in the HPFE, and move the busiest blocks accordingly. We we refer to this as "micro-tiering" within the Flash Tier.
Broader Solid State Drive options
Not everybody likes the 400GB solid state drives IBM offered for the DA loops, so IBM is now offering a smaller 200GB and a larger 800GB options as well.
Enhanced Concurrent Code Load
The new DS8870 R7.3 firmware release drastically cuts the activation time of concurrent code load in half.
Nobody likes warmstarts either. These are a necessary evil for some error conditions, but the clever engineers upstairs have figured out ways to reduce the number of warmstarts and eliminate the need to perform a warmstart after certain events to prevent any application impact to the attached host.
Multi-Target Remote Mirror
By now you know that IBM has the market-leading remote mirroring services for high-end disk systems, using less bandwidth and maintaining better concurrency than high-end systems from other vendors.
The DS8870 R7.2.7 firmware release can now support multi-target remote mirror. In previous releases, if you wanted three-site disaster recovery, you relied on Metro/Global Mirror, where site "A" had a Metro Mirror to a bunker site "B", and then site "B" had a Global Mirror to site "C". Not everybody liked this.
Some clients have asked for a "star" configuration, where "A"-to-"B" and "A"-to-"C" are independent of each other. A SCORE request is available for the following configurations:
Two Metro Mirror
One Metro Mirror and one Global Copy
Two Global Copy
While Metro Mirror can support up to 300km distance, and Global Copy can go any distance around the planet, there is no reason why you can't have one or both copies in the same building, or on campus nearby, for use with HyperSwap.
OpenStack Cinder interface support
Last but not least, the DS8870 now offers full support for OpenStack Havana and Icehouse releases. Support is provided through the OpenStack Cinder driver currently available for download. IBM is a platinum sponsor of the OpenStack foundation.
The new TS1155 enterprise tape drive can write up to 15 TB uncompressed data to existing JD/JZ/JL media.
It can read/write existing 10TB-formatted JD media, and 7TB-formatted JC media, written by former TS1150 drives. It also can offer read-only support for older 4TB-formatted JC media from TS1140 drives.
These are uncompressed capacities, and some clients achieve 2x or 3x compression on top of these capacities. This depends heavily on the type of data. Your mileage may vary, as they say.
Most of the rest of the features of the TS1150 drives carry forward., The performance 360 MB/sec is similar, encryption via IBM Security Key Lifecycle Manager (SKLM) is similar, and support for IBM Spectrum Archive via Linear Tape File System (LTFS) format is similar.
An interesting development is that the TS1155, in addition to standard 8Gb Fibre Channel attach, is the first IBM enterprise drive to also offer 10Gb Ethernet support. IBM will offer both RDMA over Converged Ethernet (RoCE) as well as iSCSI support.
The newest member of the IBM Spectrum Storage software family, IBM Spectrum Copy Data Management automates the creation of snapshot images (FlashCopy for those familiar with IBM terminology) on IBM, NetApp and EMC storage arrays. These copies can be made for various uses, such as DevOps, Dev/Test, Backup/Restore, and Disaster Recovery.
At some data centers, these copies can consume as much as 60 percent of your total storage space, because often each developer and tester are generating their own copies. Instead, having copies automated, registered, cataloged, and made available to developers and testers eliminates rogue copies.
This release adds support for additional databases, including Microsoft SQL Server on physical machines, SAP HANA in-memory databases, and Epic/Caché from InterSystems used in Electronic Health Records (EHR) management systems.
IBM also adds support for long-distance Vmotion for VMware virtual machine images. The target for this movement is IBM Spectrum Accelerate running on IBM Bluemix Cloud, supporting Hybrid Cloud configurations.
Well, it's Tuesday again, and you know what that means? IBM Announcements! This week I am in San Francisco, California speaking to clients. A bit colder than Tucson, Arizona!
(FTC Disclosure: I work for IBM. Special thanks to Mark Larson (IBM SAN team), and both Craig Nelson and Peter Schmelter from Broadcom, for their assistance with this post. I have no personal financial interest in Broadcom. This blog post can be considered a "paid celebrity endorsement" of the IBM products mentioned below.)
Spectrum Control v5.3
Back in 2003, I was the chief architect of Spectrum Control v1, formerly called TotalStorage Productivity Center, and later Tivoli Storage Productivity Center. IBM Spectrum Control is part of the IBM Spectrum Storage Suite.
There are two editions: Standard Edition and Advanced Edition.
(What happened to the other editions? The "Base Edition" is now called IBM Spectrum Connect. The "Spectrum Control Storage Insights" service in the IBM Cloud is now just called IBM Storage Insights and Storage Insights Pro.)
The Standard Edition v5.3 offers the following:
Capacity visualization and management, Performance troubleshooting, Health and performance alerting, Application modeling, and support for VMware data sources
Create, save, and send reports directly in the web UI. The reports can be run now, or scheduled to be run later. When a report is run, it can be sent by email or exported and saved in different file types.
Support IBM FlashSystem 900 AE3 models using compression, and the new IBM FlashSystem 9100
Improved automation of counting the licenses for enclosure-based storage devices
The latest IBM Copy Services Manager (CSM) v6.2 for managing remote mirroring, replacing the previous IBM Tivoli Storage Productivity Center for Replication.
The Advanced Edition v5.3 provides all of the above, as well as the following.
Tiered storage optimization with intelligent analytics
Service catalog with policy-based provisioning
Self-service provisioning with restricted use logins
Analysis of reclaimable space
Showback and Chargeback reports
Application-based snapshot management using IBM Spectrum Protect Snapshot (formerly known as IBM FlashCopy Manager, FCM)
Clients with v5.2.x version of IBM Spectrum Control can upgrade to this new release.
Clients with IBM Spectrum Virtualize-based appliances can bundle Spectrum Control v5.3 with the latest Spectrum Virtualize v8 code. This bundle is referred to as "IBM Virtual Storage Center", or VSC for short. VSC supports SAN Volume Controller, FlashSystem 9100 and V9000, Storwize V7000 and V5000 models.
IBM's announcement of NVMe-capable FlashSystem 9100 has caused many to re-evaluate their SAN infrastructure. All IBM b-type Gen5 and Gen6 switches and directors are NVMe-ready!
(Last year, Broadcom completed its acquisition of Brocade. I am thankful both start with the letter "B", so we won't have to rename our B-type switches to another letter!)
There are two new products in this announcement. The SAN 128B-6 is a Gen6 switch in a 2U container. The other is a 64-port Blade that fits into existing Gen6 Directors, like the 256B-6 or 512B-6 models.
But the 128B-6 doesn't have 128 standard ports ! It actually has 96 standard ports, plus eight "Q-Flex" ports (that can be used to create a total of 128 ports) . Likewise, the 64-port blades have 16 Q-Flex ports (that can be used to create 64 ports).
What is going on? The Q-Flex ports can actually run four channels in different colors of light over the same fiber optic cable, reducing the wiring mess. These Q-Flex can be used for host or device traffic, but are often used as "Inter-Switch Links" or ISL for short.
All of the standard and Q-Flex ports are 32Gbps, but can are capable of autosensing 4, 8, 16, and 32 Gbps port speedsm depending on the SFPs used , for interoperability with existing servers and storage devices. In the case of Q-Flex, all four colors must be run at the same speed, so a Q-Flex represents either 4x32, 4x16, 4x8 or 4x4 Gbps links. You cannot mix different speeds on a single Q-Flex.
In addition, the 64-port blade also supports 10 GbE, 25 GbE, and 40 GbE using the appropriate QSFP transceivers.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
Here is a quick recap of the October 9, 2018 announcements this week.
IBM Elastic Storage Server V5.3.2
The new IBM Elastic Storage Server v5.3.2 offers support for new drawers, non-disruptive upgrades of older models, and an optional 100GbE switch.
When the ESS was first announced, we had GSx models and GLx models, where x represented the number of storage drawers. The "S" stood for small 2U-24 drive drawers, so for example the GS4 had two Power8 servers combined with four 2U-size flash SSD drawers. The "L" stood for large 4U-60 drive nearline HDD drawers.
The second generation models append "S" for Second, so we had GS4S and GL6S. The large models changed to larger 5U-84 drive drawers. As with the previous "L" models, two slots per system contain Solid State Drives for internal use and caching, leaving the rest for slower spinning HDD disk.
Before this week, to upgrade from one model to another meant moving the data off, installing and configuring the additional drawers, and then move the data back. With today's announcements, you can now non-disruptively upgrade GS1S to GS2S to GS4S models, and GL1S to GL2S to GL4S to GL6S.
While you can federate as many GS and GL models together, that may mean having to spend more for Power8 servers than you are comfortable with, so IBM added "GHxy" Hybrid models, with x 2U-24 drive drawers, and y 5U-84 drive drawers. Initial models included the GH14 and GH24, which had one or two flash drawers, and four large drawers. This week, IBM announced a new GH12 model. The SSD flash in the 2U drawer can be 3.84TB or 15.36TB, and the nearline drives in the 5U drawers can be 4TB, 8TB or 10TB capacities.
What did IBM call the third generation GL models? Instead of using "T" which is both the next letter in the alphabet after "S", and the initial letter of the word "third", IBM instead decided to use "C" to designate CORAL project, the Collaboration of Oakridge, Argonne, and Lawrence Livermore national labs. Since the change applied only to the GL models, not the GS models, this makes sense.
To meet the requirements to build the world's fastest supercomputer for the CORAL project, IBM created a modified Elastic Storage Server model with 4U drawers that contained 106 drives. Now, these are available to the general public! IBM announced GL1C, GL2C, GL4C and GL6C models. In these, there are 2 SSD drives, and the rest are 10TB nearline drives.
The new optional 100GbE switch has 32 ports with a total of 6.4 Tbps. These can support 10, 40, 50 and 100GbE data rates, with 300 nsec latency for 100 GbE port to port
Spectrum Scale is licensed two ways: Standard Edition based on the number of sockets, with different prices for NSD servers, FPO servers and NSD clients; and the "Data Management" edition which offered advanced features, and was based on capacity of NSD, independent of the number of servers and clients attached.
Clients liked the capacity-based license model, but did not necessarily need the advanced features. In response, IBM now offers the "Data Access" edition, which offers the same features and functions of Standard Edition, but with capacity-based licensing.
For ESS models, you can chose to license by disk as before, or by capacity in combination with Spectrum Scale capacity-based deployments.
Hortonworks Data Platform v3.0.1 has followed suit. With the merger between Hortonworks and Cloudera, Hortonworks now offers capacity-based licensing for shared storage, like the IBM Elastic Storage Server.
IBM FlashSystem A9000/A9000R software version 12.3
There are three enhancements in this release: Three-site replication, a new model of A9000R, and raising a previous pool size limit.
For three-site replication, you can now combine HyperSwap which maintains two identical copies at distance, with a third asynchronous mirroring. The first two are typically within 100 km, but the third copy can be a much greater distance, across the continent if you like.
The A9000 "Pod" had three x86-based controller and one FlashCore drawer. The A9000R "Rack" had four, six or eight x86-based controllers and two, three or four FlashCore drawers, respectively, as well as a Power Distribution Unit (PDU) and pair of InfiniBand switches to connect everything together. The new "Grid Starter" model is very much like the "Pod" with three controllers and one FlashCore drawer, but adds the PDU and IB switches. The idea is that you can start with a "Grid Starter", then later upgrade to the larger A9000R models as you grow.
Back in XIV days, the architectural limit per pool of 1PB was plenty big. But with the new capacities on the A9000 and A9000R, the 1PB limit was starting to draw complaints. This limit was lifted, so that now a single pool can be made with the entire capacity of the box.
In the mainframe world, IBM Geographically Dispersed Parallel Sysplex, now just GDPS, provide the highest BC-7 business continuity tier, providing end-to-end coordination with servers, networks and storage devices. For IBM Power Systems, similar BC-7 support is provided by IBM Geographically Dispersed Resiliency.
In this week's announcement, IBM Geographically Dispersed Resiliency (GDR) for Power Systems has been renamed and now offered in two editions: VM Recovery Manager HA and VM Recovery Manager DR. The "HA" edition provides high availability using Power Systems Live Partition Mobility for AIX, IBM i and Linux operating systems.
The "DR" edition provides both High Availability and Disaster Recovery capabilities, supporting mirrored storage systems like IBM DS8000, SAN Volume Controller, FlashSystem 9100 and V9000, and Storwize systems, as well as competitive storage from Dell EMC and Hitachi.
Next week, I will be in Hollywood, Florida for IBM Technical University (Oct 15-19), and then Rome for the IBM Technical University (Oct 22-26). I will be covering many of these announcements above, and more!
Well, it's Tuesday again, and you know what that means? IBM Announcements!
(OK, yes, today is Friday, but I was busy getting married on Tuesday, so IBM pushed the announcements out one day to Wednesday, and technically I am writing this blog post during my honeymoon vacation, so the IBM marketing team and my new wife both cut me some slack. Work/Life balance is all about compromises, right?)
IBM DS8880 Storage System
The IBM DS8880 comes in three models, the DS8884 entry level, the DS8886 enterprise level, and the DS8888 all-flash array. IBM offers 1, 2, 3 and 4 year warranties.
The new High Performance Flash Enclosure (HPFE) Gen2 delivers more capacity than Gen1. The 2U flash enclosures are configured in pairs with each enclosure supporting up to twenty-four 2.5-inch flash cards in capacities 400 GB, 800 GB, 1.6 TB and 3.2 TB.
The HPFE Gen2 are currently available for both the DS8884 and DS8886 models. The maximum flash capacity for the DS8886 increases from 96 TB to 614.4 TB, delivering reduced storage costs through lesser cost per IOPS with this new flash enclosure. IBM has made a statement of direction to offer these HPFE Gen2 on the DS8888 as well.
To improve security, IBM DS8880 now supports customer-defined digital certificates for authentication, and configurable Hardware Management Console (HMC) firewall support.
For IBM's mainframe clients, IBM now offers "Extents-level" space release support for z/OS®, DSCLI (Command Line Interface) support for z/OS environment, and FICON® Information Unit (IU) pacing improvements.
IBM Spectrum Virtualize™ V7.8 delivers support for the latest SAN Volume Controller, FlashSystem V9000 and Storwize® product family, and adds new software functionality and improvements
In conjunction with [IBM Spectrum Copy Data Management], Spectrum Virtualize v7.8 offers flexible data protection with transparent cloud tiering to leverage the cloud as FlashCopy targets and restore these snapshots from the cloud on select platforms.
However, the encryption keys are kept on USB thumb drives, which are either left in the USB ports on the back of the hardware, or locked away in a safe, only to be retrieved as needed when rebooting the systems or upgrading the firmware.
Now, IBM Spectrum Virtualize v7.8 supports the IBM Security Key Lifecycle Manager (SKLM) to manage encryption keys. IBM continues to support USB thumb drives if you prefer, but SKLM is used to manage keys for most of the rest of IBM products, and provides centralized management.
The SVC and Storwize models can directly attach via 12Gb SAS to expansion drawers. At the time, we supported 2U-high 12-bay that support Large Form Factor (LFF) 3.5-inch Nearline (7200 rpm) drives, and 2U-high 24-bay that support the Small Form Factor (SFF) 2.5-inch drives (SSD, 15K, 10K and 7200 rpm).
With Spectrum Virtualize v7.8, IBM now offers a third option, the 5U-high 92-bay that supports both LFF and SFF drives. This new expansion can be attached to Storwize V5000 Gen2, Storwize V7000 (models 524/Gen2 and 624/Gen2+), and SVC (models DH8 and SV1).
For the 12-bay and 92-bay, IBM now supports 10TB capacity 3.5-inch Nearline drives. For the 24-bay and 92-bay, IBM now supports 7.68 TB and 15.36 TB capacity Solid State Drives (SSD).
For those concerned about the phrase "lower endurance" in the press release, let me explain. SSD have a bit of extra capacity included. If you write the full capacity of the drive every day for a year, you will "burn up" about one percent of the capacity.
To handle ten "Full Drive Writes per Day" (10 FDWP) over the course of five years, IBM adds 50 percent extra spare capacity above the 400 GB, 800 GB, 1.6 TB and 3.2 TB capacities. So, a 400GB full-endurance drive is really 600 GB inside. These were sometimes referred to as "Enterprise" SSD.
For the larger device sizes, the IT industry has determined that 1 FDWP is sufficient, so instead of 50 percent spare capacity, IBM adds only 5 percent extra. The 7.68 TB is really 8.06 TB inside. These were earlier referred to as "Read-Intensive" SSD. These come in 1.92 TB, 3.84 TB, 7.68 TB and 15.36 TB capacities.
IBM is also offering non-disruptive model conversions. Storwize V5010 can now be converted to V5020, and V5020 can be converted to V5030. The Storwize V7000 Model 524 (Gen2) can be converted to model 624 (Gen2+).
The DeepFlash 150 is the perfect JBOF addition to the ESS family. The current ESS models had either 2U-high 24-drive bays, or 4U-high 60-drive bays. This new model is 3U-high with 64 high-capacity (8 TB) Board Solid State Drives (BSSD).
The ESS includes all the features of IBM Spectrum Scale, including both 8+2 and 8+3 Erasure Coding data protection. This provides file and object access to data, including POSIX compliance for Windows, Linux and AIX operating systems, as well as HDFS-compliant access for big data analytics.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM Storwize V5030F and V7000F all-flash high-density expansion enclosure
The 5U-high, 92-drive expansion enclosure introduced for the IBM Storwize V5000 and V7000 is now available for the all-flash models V5030F and V7000F. High-density expansion enclosure Model A9F requires IBM Spectrum Virtualize Software V7.8, or later, for operation.
The enclosure allows any mix of "Tier 0" write-endurance SSD at 1.6TB and 3.2TB capacities, and "Tier 1" read-intensive SSD at 1.92TB, 3.84TB, 7.68TB and 15.36TB capacities.
Storwize V5030F control enclosure models support attachment of up to 40U of expansion enclosures, which equates to eight high-density expansion enclosures, up to 760 drives per control enclosure, and up to 1,056 per clustered system.
Storwize V7000F control enclosure models support attachment of up to eight high-density expansion enclosures, up to 760 drives per control enclosure, and up to 3,040 drives per clustered system.
IBM has adopted "Agile" process for all of its IBM Spectrum Storage software. Spectrum Virtualize is offered in a variety of forms. IBM offers the FlashSystem V9000, SAN Volume Controller, Storwize family, and Spectrum Virtualize as software that runs on Lenovo and SuperMicro servers. This means quarterly delivery of new features and functions!
Lots of small enhancements were added in this release:
Apply Quality-of-Service (QoS) to a Host Cluster in terms of IOPS and or MB/s throughput.
SAN Congestion reporting, via buffer credit starvation reporting in Spectrum Control and via the XML statistics reporting, for the 16Gbps FCP Host Bus Adapter (HBA).
Resizing for Metro Mirror and Global Mirror remote copy services of thin provisioned volumes.
Consistency Protection for Metro Mirror and Global Mirror. You can now define "Change Volumes" to be used in the event of problems with MM or GM, it will switch over to GMCV mode.
Increased FlashCopy Background Copy Rates
Proactive Host Failover during temporary and permanent node removals from cluster
