Continuing my coverage of the IBM Dynamic Infrastructure Executive Summit at the Fairmont Resort in Scottsdale, Arizona, we had a day full main-tent sessions. Here is a quick recap of the sessions presented in the afternoon.
Taming the Information Explosion
Doug Balog, IBM Vice President and Disk Storage Business Line Executive, presented on the information explosion. Storage Admins are focused on managing storage growth and the related costs and complexity, proper forecasting and capacity planning, and backup administration. IBM's strategy is to help clients in the following areas:
Storage Efficiency - getting the most use out of the resources you invest
Service Delivery - ensuring that information gets to the right people at the right time
Data Protection - protecting data against unethical tampering, unauthorized access, and unexpected loss and corruption
Cory Vokey, Senior Manager of IT Systems Operations at Research in Motion, Ltd., the people who bring you BlackBerry phone service, provided a client testimonial for the XIV storage system. Before the XIV, RIM suffered high storage costs and per-volume software licensing. Over the past 15 months, RIM deployed XIV as a corporate standard. With the XIV, they have had 100 percent up-time, and enjoyed 50 percent costs savings compared to their previous storage systems. They have increased capacity 300 percent, without any increase to their storage admin staff. XIV has greatly improved their procurement process, as they no longer need to "true up" their software licenses to the volume of data managed, a sore point with their previous storage vendor.
Mainframe Innovations and Integration
Tom Rosamillia, IBM General Manager of the System z mainframe platform, presented on mainframe servers. After 40 years, IBM's mainframe remains the gold standard, able to handle hundreds of workloads on a single server, facilitating immediate growth with scalability. The key values of the System z mainframe are:
Industry leading virtualization, management and qualities of service
A comprehensive portfolio for business intelligence and data warehousing
The premier platform for modernizing the enterprise
A large and growing portfolio of leading-applications ISV support
Steve Phillips, CIO of Avnet, presented the client testimonial for their use of a System z10 mainframe. Last year, Avnet was ranked Fortune's Number One "Most admired" for Technology distribution. Avnet distributes technology from 300 suppliers to over 100,000 resellers, ISVs and end users. They have modernized their system running SAP on System z with DB2 as the database management system, using Hypersockets virtual LAN inside the server to communicate between logical partitions (LPARs). The folks at Avnet especially like the ability for on-the-fly re-assignment of capacity. This is used for end-of-quarter peak processing, and to adjust between test and development workloads. They also like the various special purpose engines available:
z Integrated Information Processor (zIIP) for DB2 workloads
z Application Assist Processor (zAAP) for Java processing under WebSphere
Integrated Facility for Linux (IFL) for Linux applications
Cloud Computing: Real Capabilities, Real Stories
Mike Hill, IBM Vice President of Enterprise Initiatives, presented on IBM's leadership in cloud computing. He covered three trends that are driving IT today. First, there is a consumerization and industrialization of IT interfaces. Second, a convergence of the infrastructure that is driving a new focus on standards. Third, delivering IT as a service has brought about new delivery choices. The result is cloud computing, with on-demand self-service, ubiquitous network access, location-independent resource pooling, rapid elasticity, and flexible pricing models. Government agencies and businesses in Retail, Manufacturing and Utilities are leading the charge to cloud computing.
Mike covered IBM's five cloud computing deployment models, and shared his views on which workloads might be ready for cloud, and which may not be there yet. Organizations are certainly seeing significant results: reduced labor costs, improved capital utilization, reduced provisioning cycle times, improved quality through reduced software defects, and reduced end user IT support costs.
Mitch Daniels, Director of Technology at ManTech International Corporation, presented the customer testimonial for an IBM private cloud for Development and Test. Mantech chose a private cloud as they work with US Federal agencies like Department of Defense, Homeland Security and the Intelligence community. The private cloud was built from:
IBM Cloudburst virtualized server environment
Tivoli Unified Process to document process and workflow
Tivoli Service Automation Manager to request, deliver and manage IT services
Tivoli Self-Service Portal and Service Catalog to allow developers and testers to request resources as needed
The result: Mantech saved 50 percent in labor costs, and can now provision development and test resources in minutes instead of weeks.
The IBM Transformation Story
Leslie Gordon, IBM Vice President of Application and Infrastructure Services Management, presented IBM's own transformation story, becoming the premier "Globally Integrated Enterprise". Based on IBM's 2009 CIO study, CIOs must balance three roles with seemingly contradictory demands:
Make innovations real, be both an insightful visionary but also an able pragmatist
Raise the Return on Investment (ROI) of IT, determine savvy ways to create value but also be ruthless at cutting costs
Expanding the business impact of IT, be a collaborative business leader with the other C-level executives, but also be an inspiring manager for the IT staff.
In this case, IBM drinks its own champagne, using its own solutions to help run its internal operations. In 1997, IBM used over 15,000 applications, but this has been simplified down to 4500 applications today. Thousands of servers were consolidated to Linux on System z mainframes. The applications workloads were categorized as Blue, Bronze, Silver, and Gold to help prioritize the consolidation. IBM's key lessons from all this were:
Gather data at the business unit level, but build the business case from an enterprise view.
Start small and monitor progress continually, run operations concurrently with transformational projects
Address cultural and organizational changes by deploying transformation in waves
I found the client testimonials insightful. It is always good to hear that IBM's solutions work "as advertised" right out of the box.
This week, Tuesday, Wednesday and Thursday, I am at the IBM Dynamic Infrastructure Executive Summit at the beautiful Fairmont Resort in Scottsdale, Arizona. This is a mix of indoor and outdoor meetings, one-on-ones with IBM executives, and main-tent sessions.
The Solutions Showcase will cover the following:
As the bar for performance gets higher and the need to manage, store and analyze massive amounts of information escalates, systems must scale to meet the needs of the business. The latest server and storage technology innovations including: POWER7, eX5, XIV, ProtecTIER, SONAS, and System z Solution Editions.

Discover how IBM can help you manage your ever-increasing amount of information with an end-to-end, innovative approach to building a dynamic infrastructure. You will learn all of our innovative solutions and find out how you can effectively transform your enterprise for a smarter planet.
Well it's Wednesday, and you know what that means... IBM Announcements.
(Normally, announcements are on Tuesdays, but we moved this one over to Wednesday to line up with our big launch event in Pinehurst, NC. )
A lot was announced today, so I decided to break it up into several separate posts. I will start with our Enterprise Systems: DS8870, TS7700 Release 3, and XIV Gen3.
Enterprise systems are the servers, storage and software at the core of an enterprise IT infrastructure. Enterprise systems enable a private cloud infrastructure at enterprise scale, with flexible service delivery models that provide dynamic efficiency for resource and workload management. They make sure critical data is always available across the enterprise, making it accessible in new ways so that actionable insights can be derived from advanced and operational analytics. They also provide ultimate security, ensuring the integrity of critical data while mitigating risk and providing assured compliance.
IBM System Storage DS8870® disk system
This new storage system is the next generation in IBM's DS8000 series, based on IBM's POWER7 chipset. Each CEC can have 2, 4, 8 or 16 cores. Like the DS8800, you can have a mix of 2.5-inch and 3.5-inch disk drives of different speeds and capacities, up to 1,536 drives in a four-frame configuration. The maximum cache is now 1TB usable. The combination of faster chipset and more cache can triple performance for some workloads!
All DS8870s ship standard with all Full Disk Encryption (FDE-capable) drives. The problem in the past was that people would buy DS8000 with non-FDE drives, and then later want to activate encryption, and discovered that they have to swap out their drives with those with the encryption chip built in. Now, all drives on the DS8870 will have the encryption chip. This also allows Easy Tier sub-volume automated tiering to move encrypted data between all media types.
Flash optimization with DS8000 Easy Tier can improve performance up to 3 times with 3% of data on solid-state storage. Easy Tier is easy to deploy and runs automatically.
Support of the American National Standards Institute's (ANSI) T10 Data Integrity Field (DIF) standard. This is a feature that the mainframe has had for years, and is now being extended to distributed operating systems. The concept is simple. When sending data between server and storage, generate a checksum at the source, and then validate the checksum at the target. When you write a block of data, the server generates the checksum, and the DS8870 validates the checksum on arrival. When you read the data back, the DS8870 generates the checksum, and the server validates it on arrival. This ensures that data was not corrupted in between. There is a great write-up on IBM developerWorks: [End-to-end data protection using T10 standard data integrity field].
Energy Efficient. The DS8870 consumes less energy than its predecessor, the DS8800. For example, a fully-configured four-frame DS8870 with 1,536 disk drives consumes only 23.2kW, compared to the same number of drives in a DS8800 consumed 26.3 kW. By comparison, the DS8700 with five frames and 1,024 drives consumed 29.2kW.
Support for new System z load balancing algorithm. System z Workload Manager now interacts with the DS8870 I/O Priority Manager to optimize designated Quality of Service (QoS) levels. We have also the fastest operational analytics solution with DB2 list Prefetch cache optimization with DS8870 High Performance FICON (zHPF) integration. This solution increases DB2 query performance up to 11 times with disk, and up to 60 times with solid-state drives (SSD). File scans are up to 30 percent faster using DS8870 zHPF support for sequential access methods (QSAM, BPAM, and BSAM).
VMware vStorage APIs for Array Integration (VAAI) support. Why should the IBM DS8800 series support VMware when IBM already offers great VMware support with SAN Volume Controller (SVC), Storwize V7000 and XIV storage sytsems? Good question. This was hotly debated between development and marketing. Several DS8000 customers have already added SVC to provide full VMware VAAI support. As a consultant, I am neither development nor marketing, but felt it necessary to weigh in on my opinion on this. The DS8000 is a consolidation platform. According to one analyst survey, 22 percent of companies run on a single disk platform, so for DS8000 to be the one, it needs to support VMware and exploit these special APIs.
Six Nines Availability. Critical enterprise systems need to deliver continuous data availability, or very close to it. IBM solutions can help deliver up to six “nines” of availability, or 99.9999 percent when combining DS8000 Metro Mirror and GDPS Hyperswap. That's less than 30 seconds of downtime per year.
The TS7700 Release 3 represents a refresh to our existing virtual tape libraries. These are mainframe-only, offered in two models: TS7720 is a disk-only device, and the TS7740 is a blended disk-and-tape solution.
Industry standard hardware encryption. This applies to user data stored on the TS7700 system cache (disk), and for data transferred between TS7700 systems. This is especially important for regulations, like Payment Card Industry Data Security Standard (PCI-DSS). In previous models, the data would not be encrypted until it was moved off disk and written to tape. Now, it is encrypted the minute in lands on the disk cache, and stays encrypted as it is replicated from one TS7700 to another in the grid.
Up to 4 Million logical volume capacity. This is twice the previous support.
More physical capacity for TS7720 systems. The maximum capacity for the disk-only model is raised from 440TB to 620TB, representing a 40 percent increase.
My latest book "Inside System Storage: Volume V" is now available!
I have published my fifth volume in my "Inside System Storage" series! Currently, it is only available in Paperback. My editor, Susan Pollard, is hoping to have the eBook and Hardcover versions ready for Cyber Monday. The foreword was written by my Dr. Sondra Ashmore.
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-300-26223-7.
Improved Scalability. A new Multi-system Manager (MSM) server reduces the operational complexity for large and multi-site XIV deployments. Previously, admins connected directly to XIV boxes. If you had 10 admins logged in, then every XIV box was managing 10 admin conversations. The new MSM acts as a go-between. The admins connect to the MSM, and the MSM connects to the XIV boxes. The MSM polls and caches the status of each XIV, greatly increasing the number of XIV boxes that an admin can manage.
Enhanced User Interface. A new Multi-system Manager server reduces the operational complexity for large and multi-site XIV deployments. We also added support for IPsec and US. Government (USGv6) certification for admistering the XIV over IPv6 networks. The XIV Mobile Dashboard app for iPhone and iPad is spiffed up. Finally, the GUI has been internationalized and translated to the Japanese language.
Enhanced Integration for Cloud. For OpenStack, XIV now offers a Nova-volume driver which provides persistent storage to OpenStack compute nodes. The Nova task force is now looking to move storage into its own project called Cinder. For VMware, XIV has full support for Site Recovery Manager (SRM) v4.1 and v5.0 releases. XIV now also supports the Microsoft System Center Virtual Machine Manager, which can manage Hyper-V, VMware and Citrix XenServer hypervisors.
Smaller entry point. The original XIV supported 1TB and 2TB drives, with the smallest offering being 27TB usable. When IBM introduced the XIV Gen3, the two choices were 2TB and 3TB disk drives. Unfortunately, this meant that the initial entry model was now 55TB in size, and each additional module would be more expensive as well. IBM is now going to offer 1TB support for XIV Gen3 for a lower price point, these are actually 2TB drives with half the capacity turned off.
Full VMware Vstorage API for Array Integration (VAAI). Back in 2008, VMware announced new vStorage APIs for its vSphere ESX hypervisor: vStorage API for Site Recovery Manager, vStorage API for Data Potection, vStorage API for Multipathing. Last July, VMware added a new API called vStorage API for Array Integration [VAAI] which offers three primitives:
Hardware-assisted Blocks zeroing. Sometimes referred to as "Write Same", this SCSI command will zero out a large section of blocks, presumably as part of a VMDK file. This can then be used to reclaim space on the XIV on thin-provisioned LUNs.
Hardware-assisted Copy. Make an XIV snapshot of data without any I/O on the server hardware.
Hardware-assisted locking. On mainframes, this is call Parallel Access Volumes (PAV). Instead of locking an entire LUN using standard SCSI reserve commands, this primitive allows an ESX host to lock just an individual block so as not to interfere with other hosts accessing other blocks on that same LUN.
Quality of Service (QoS) Performance Classes.
When XIV was first released, it treated all hosts and all data the same, even when deployed for a variety of different applications. This worked for some clients, such as [Medicare y Mucho Más]. They migrated their databases, file servers and email system from EMC CLARiiON to an IBM XIV Storage System. In conjunction with VMware, the XIV provides a highly flexible and scalable virtualized architecture, which enhances the company's business agility.
However, other clients were skeptical, and felt they needed additional "nobs" to prioritize different workloads. The new 10.2.4 microcode allows you to define four different "performance classes". This is like the door of a nightclub. All the regular people are waiting in a long line, but when a celebrity in a limo arrives, the bouncer unclips the cord, and lets the celebrity in. For each class, you provide IOPS and/or MB/sec targets, and the XIV manages to those goals. Performance classes are assigned to each host based on their value to the business.
Offline Initialization for Asynchronous Mirror.
Internally, we called this Truck Mode. Normally, when a customer decides to start using Asynchronous Mirror, they already have a lot of data at the primary location, and so there is a lot of data to send over to the new XIV box at the secondary location. This new feature allows the data to be dumped to tape at the primary location. Those tapes are shipped to the secondary location and restored on the empty XIV. The two XIV boxes are then connected for Asynchronous Mirroring, and checksums of each 64KB block are compared to determine what has changed at the primary during this "tape delivery time". This greatly reduces the time it takes for the two boxes to get past the initial synchronization phase.
IP-based Replication. When IBM first launched the Storwize V7000 last October, people commented that the one feature they felt missing was IP-based replication. Sure, we offered FCP-based replication as most other Enterprise-class disk systems offer today, but many midrange systems also offer IP-based repliation to reduce the need for expensive FCIP routers. [IBM Tivoli Storage FastBack for Storwize V7000] provides IP-based replication for Storwize V7000 systems.
Network Attached Storage
IBM announced two new models of the IBM System Storage N series. The midrange N6240 supports up to 600 drives, replacing the N6040 system. The entry-level N6210 supports up to 240 drives, and replaces the N3600 system. Details for both are available on the latest [data sheet].
IBM Real-Time Compression appliances work with all N series models to provide additional storage efficiency. Last October, I provided the [Product Name Decoder Ring] for the STN6500 and STN6800 models. The STN6500 supports 1 GbE ports, and the STN6800 supports 10GbE ports (or a mix of 10GbE and 1GbE, if you prefer). The IBM versions of these models were announced last December, but some people were on vacation and might have missed it. For more details of this, read the [Resources page], the [landing page], or [watch this video].
IBM System Storage DS3000 series
IBM System Storage [DS3524 Express DC and EXP3524 Express DC] models are powered with direct current (DC) rather than alternating current (AC). The DS3524 packs dual controllers and two dozen small-form factor (2.5 inch) drives in a compact 2U-high rack-optimized module. The EXP3524 provides addition disk capacity that can be attached to the DS3524 for expansion.
Large data centers, especially those in the Telecommunications Industry, receive AC from their power company, then store it in a large battery called an Uninterruptible Power Supply (UPS). For DC-powered equipment, they can run directly off this battery source, but for AC-powered equipment, the DC has to be converted back to AC, and some energy is lost in the conversion. Thus, having DC-powered equipment is more energy efficient, or "green", for the IT data center.
Whether you get the DC-powered or AC-powered models, both are NEBS-compliant and ETSI-compliant.
New Tape Drive Options for Autoloaders and Libraries
IBM System Storage [TS2900 Autoloader] is a compact 1U-high tape system that supports one LTO drive and up to 9 tape cartridges. The TS2900 can support either an LTO-3, LTO-4 or LTO-5 half-height drive.
IBM System Storage [TS3100 and TS3200 Tape Libraries] were also enhanced. The TS3100 can accomodate one full-height LTO drive, or two half-height drives, and hold up to 24 cartridges. The TS3200 offers twice as many drives and space for cartridges.
Continuing my romp through Australia and New Zealand, the last Storage Optimisation Breakfast of the week was Brisbane, which the locals here refer to as [Brisvegas], probably for all of the nightlife and casinos here.
The IBM office building is conveniently across the street from my hotel, the [Sofitel Brisbane]. The hotel also sits above central station, which allows quick transportation to the airport.
This time, we had a tag team of two people from James Cook University (JCU) to present their success story. First up was Kent Adams, the Director or Information Technology and Resources. JCU is recognized as one of the top 5 percent of Universities worldwide, and as a result, their data storage requirements are growing at 400 percent per year! Their latest purchase put out for RFP was for at least 40TB that could handle at least 20,000 IOPS. The winning solutions was an IBM XIV disk system.
Behind the scenes at all the events this week here in Australia were, from left to right, Natalie from GPJ Australia, the local subsidiary of the George P. Johnson events management we use in the states; Sonia Phillips, IBM Advisory Marketing Lead for Dynamic Infrastructure Optimisation and Cloud Computing, Demand Programs, for Australia and New Zealand; and Monika Lovgren, IBM Marketing and Execution Lead for Workload Optimised Systems for Australia.
The second speaker was Lee Askew, one of the Storage Administrators. Overall, the JCU team have been amazed at how well this box works. When they started it up, they expected to spend the next 24-36 hours formatting RAID ranks, but not with the XIV. It was ready in 2 minutes and they started provisioning storage right away. Their own tests to fail a drive found they can do a full rebuild to redundancy in 9 minutes. It took 8-36 hours on their previous disk array. Failing a full data module took only 75 minutes to bring back to redundancy.
After a long and tiring week, I was able to relax by walking through this beautiful King Edward park near the IBM building. This had a nice variety of plants and flowers, and with the surprise visit of a lizard about the length of my arm that crossed my path.
JCU also uses Asynchronous Mirror to replicate data to another XIV at distance. Again, as with all aspects of IBM XIV, the solution works as advertised. They are well positioned to grow from the 18,000 students they have today, to their target goal of 25,000 students they want to have by 2015.
Worldwide, IBM has done well with colleges and universities, and this was a great example of how partnering with IBM for your IT infrastructure can make a huge difference!
Wrapping up my seven-city romp through Australia and New Zealand, the final city was Canberra, which is the capital of Australia. As with Wellington, this meant many of the clients in the audience work in government agencies.
I had not taken any photos of Anna Wells, IBM Storage Sales Leader for ANZ, but I was able to find this caricature of her on a poster from an award she won within IBM.
I also did not have a picture of Robert, my videographer for this trip, who was always behind the camera himself.
The event went smoothly, just like the rest of them. Anna presented IBM's storage strategy and highlighted specific IBM storage solutions.
I had several emails asking if this event was called "Storage Optimisation Breakfast" because it was held in the mornings, or did we actually serve food at these events. The answer is we actually served food, a variation of the [Full English Breakfast], and most of the attendees gobbled it down while Anna spoke.
The fare was quite similar across all seven locations: scrambled or poached eggs, on toast or english muffin, ham/bacon/sausages, potatoes or mushrooms, and half of a baked tomato with bits of something toasted on top.
One morning, for a change, I decided instead to have a bowl of Weet-Bix cereal. Tasted like cardboard. I learned my lesson.
Next, we had Will Quodling, Manager of Infrastructure Operations, at Australia's Department of Innovation, Industry, Science and Research. The Department of Innovation, Industry, Science and Research consists of 3200 staff that strive to encourage the sustainable growth of Australian industries. The Department is committed to developing policies and delivering programs to provide lasting economic benefits ensuring Australia's competitive future, undertakes analysis, and provides services and advice to the business, science and research community. American President, Barack Obama, visited Australia and was interested in adopting a similar concept for the United States.
The department was looking to replace their existing IBM System Storage DS4800 disk systems with something more energy efficient. They selected IBM XIV storage system, with an expected savings of 10kW per year. They are able to run 800 VMware images and 150 VDI workstations using storage on one XIV, replicate the data to a second XIV at a remote location, and have a third XIV for their Web serving environment. They tested out both single drive and full module failures, and experienced better-than-expected rebuild times, with no impact to users, and no impact to performance.
After 17 days without a functioning government, Australia finally selected a prime minister. Her name is Julia Gillard, shown here. She won in part by promising to build a National Broadband Network (NBN) for the entire country, including the rural areas.
[Canberra] is an interesting town, a fully planned community designed in 1913 by Chicago's husband-and-wife architect team of Walter Burley Griffin and Marion Mahony Griffin. The location was selected as being half-way compromise between Australia's two largest cities, Sydney and Melbourne.
I would like to thank all the wonderful people in both Australia and New Zealand for making this a successful trip!
If you store your VMware bits on external SAN or NAS-based disk storage systems, this post is for you. The subject of the post, VM Volumes, is a potential storage management game changer!
Fellow blogger Stephen Foskett mentioned VM Volumes in his [Introducing VMware vSphere Storage Features] presentation at IBM Edge 2012 conference. His session on VMware's storage features included VMware APIs for Array Integration (VAAI), VMware Array Storage Awareness (VASA), vCenter plug-ins, and a new concept he called "vVol", now more formally known as VM Volumes. This post provides a follow-up to this, describing the VM Volumes concepts, architecture, and value proposition.
"VM Volumes" is a future architecture that VMware is developing in collaboration with IBM and other major storage system vendors. So far, very little information about VM Volumes has been released. At VMworld 2012 Barcelona, VMware highlights VM Volumes for the first time and IBM demonstrates VM Volumes with the IBM XIV Storage System (more about this demo below). VM Volumes is worth your attention -- when it becomes generally available, everyone using storage arrays will have to reconsider their storage management practices in a VMware environment -- no exaggeration!
But enough drama. What is this all about?
(Note: for the sake of clarity, this post refers to block storage only. However, the VM Volumes feature applies to NAS systems as well. Special thanks to Yossi Siles and the XIV development team for their help on this post!)
The VM Volumes concept is simple: VM disks are mapped directly to special volumes on a storage array system, as opposed to storing VMDK files on a vSphere datastore.
The following images illustrate the differences between the two storage management paradigms.
You may still be asking yourself: bottom line, how will I benefit from VM Volumes?
Well, take a VM snapshot for example. With VM Volumes, vSphere can simply offload the operation by invoking a hardware snapshot of the hardware volume. This has significant implications:
VM-Granularity: Only the right VMs are copied (with datastores, backing up or cloning individual-VM portions of hardware snapshot of a datastore would require more complex configuration, tools and work)
Hardware Offload: No ESXi server resources are consumed
XIV advantage: With XIV, snapshots consume no space upfront and are completed instantly.
Here's the first takeaway: With VM Volumes, advanced storage services (which cost a lot when you buy a storage array), will become available at an individual VM level. In a cloud world, this means that applications can be provisioned easily with advanced storage services, such as snapshots and mirroring.
Now, let's take a closer look at another relevant scenario where VM Volumes will make a lot of difference - provisioning an application with special mirroring requirements:
VM Volumes case: The application is ordered via the private cloud portal. The requestor checks a box requesting an asynchronous mirror. He changes the default RPO for his needs. When the request is submitted, the process wraps up automatically: Volumes are created on one of the storage arrays, configured with a mirror and RPO exactly as specified. A few minutes later, the requestor receives an automatic mail pointing to the application virtual machine.
Datastores case #1: As may be expected, a datastore that is mirrored with the special RPO does not exist. As a result, the automated workflow sets a pending status on the request, creates an urgent ticket to a VMware administrator and aborts. When the VMware admin handles that ticket, she re-assigns the ticket to the storage administrator, asking for a new volume which is mirrored with the special RPO, and mapped to the right ESXi cluster. The next day, the volume is created; the ticket is re-assigned to the storage admin, with the new LUN being pointed to. The VMware administrator follows and creates the datastore on top of it. Since the automated workflow was aborted, the admin re-assigns the ticket to the cloud administrator, who sometime later completes the application provisioning manually.
Datastores case #2: Luckily for the requestor, a datastore that is mirrored with the special RPO does exist. However, that particular datastore is consuming space from a high performance XIV Gen3 system with SSD caching, while the application does not require that level of performance, so the workflow requires a storage administrator approval. The approval is given to save time, but the storage administrator opens a ticket for himself to create a new volume on another array, as well as a follow-up ticket for the VMware admin to create a new datastore using the new volume and migrate the application to the other datastore. In this case, provisioning was relatively rapid, but required manual follow up, involving the two administrators.
Here's the second takeaway: With VM Volumes, management is simplified, and end-to-end automation is much more applicable. The reason is that there are no datastores. Datastores physically group VMs that may otherwise be totally unrelated, and require close coordination between storage and VMware administrators.
Now, the above mainly focuses on the VMware or cloud administrator perspective. How does VM Volumes impact storage management?
VM's are the new hosts: Today, storage administrators have visibility of physical hosts in their management environment. In a non-virtualized environment, this visibility is very helpful. The storage administrator knows exactly which applications in a data center are storage-provisioned or affected by storage management operations because the applications are running on well-known hosts. However, in virtualized environments the association of an application to a physical host is temporary. To keep at least the same level of visibility as in physical environments, VMs should become part of the storage management environment, like hosts. Hosts are still interesting, for example to manage physical storage mapping, but without VM visibility, storage administrators will know less about their operation than they are used to, or need to. VM Volumes enables such visibility, because volumes are provided to individual VMs. The XIV VM Volumes demonstration at VMworld Barcelona, although experimental, shows a view of VM volumes, in XIV's management GUI.
Here's a screenshot:
That's not all!
Storage Profiles and Storage Containers: A Storage Profile is a vSphere specification of a set of storage services. A storage profile can include properties like thin or thick provisioning, mirroring definition, snapshot policy, minimum IOPS, etc.
Storage administrators define a portfolio of supported storage services, maintained as a set of storage profiles, and published (via VASA integration) to vSphere.
VMware or cloud administrators define the required storage profiles for specific applications
VMware and storage administrators need to coordinate the typical storage requirements and the automatically-available storage services. When a request to provision an application is made, the associated storage profiles are matched against the published set of available storage profiles. The matching published profiles will be used to create volumes, which will be bound to the application VMs. All that will happen automatically.
Note that when a VM is created today, a datastore must be specified. With VM Volumes, a new management entity called Storage Container (also known as Capacity Pool) replaces the use of datastore as a management object. Each Storage Container exposes a subset of the available storage profiles, as appropriate. The storage container also has a capacity quota.
Here are some more takeaways:
New way to interface vSphere and storage management: Storage administrators structure and publish storage services to vSphere via storage profiles and storage containers.
Automated provisioning, out of the box: The provisioning process automatically matches application-required storage profiles against storage profiles available from the specified storage containers. There is no need to build custom scripts and custom processes to automate storage provisioning to applications
The XIV advantage:
XIV services are very simple to define and publish. The typical number of available storage profiles would be low. It would also be easy to define application storage profiles.
XIV provides consistent high performance, up to very high capacity utilization levels, without any maintenance. As a result, automated provisioning (which inherently implies less human attention) will not create an elevated risk of reduced performance.
Note: A storage vendor VASA provider is required to support VM Volumes, storage profiles, storage containers and automated provisioning. The IBM Storage VASA provider runs as a standalone service that needs to be deployed on a server.
To summarize the VM Volumes value proposition:
Streamline cloud operation by providing storage services at VM and application level, enabling end-to-end provisioning automation, and unifying VMware and storage administration around volumes and VMs.
Increase storage array ROI, improve vSphere scalability and response time, and reduce cloud provisioning lag, by offloading VM-level provisioning, failover, backup, storage migration, storage space recycling, monitoring, and more, to the storage array, using advanced storage operations such as mirroring and snapshots.
Simplify the adoption of VM Volumes using XIV, with smaller and simpler sets of storage profiles. Apply XIV's supreme fast cloning to individual VMs, and keep automation risks at bay with XIV's consistent high performance.
Until you can get your hands on a VM Volumes-capable environment, the VMware and IBM developer groups will be collaborating and working hard to realize this game-changing feature. The above information is definitely expected to trigger your questions or comments, and our development teams are eager to learn from them and respond. Enter your comments below, and I will try to answer them, and help shape the next post on this subject. There's much more to be told.
Special thanks to Anthony Vandewerdt, who sent me his version of this presentation that he planned to present in Australia next week. I "smartened it up" (or whatever the appropriate phrase is the opposite of "dumbed it down") for the technical audience.
Recovery procedures for single and double drive failures. A double drive failure on an XIV typically involves less recovery effort than traditional RAID5-based disk systems, and in many cases results in no data loss whatsoever. I provided details on this in my blog post [Double Drive Failure Debunked: XIV Two Years Later], so no need to repeat myself here.
Replacing the Automatic Transfer Switch (ATS) non-disruptively. To support either single-phase and triple-phase power sources, the XIV uses an ATS to take two independent power feeds, and distribute this out to the three Uninterruptible Power Supplies (UPS).
Built-in Migration capability to copy data off other disk systems over to the XIV.
Configuring Synchronous and Asynchronous mirroring using either the Fibre Channel or Internet Protocol ports.
Optimizing the use of XIV for VMware, AIX and other operating systems.
The IBM XIV Storage System is quite popular in New Zealand, with four times more boxes sold per capita than the other countries in the Asia Pacific region. I covered both the A14 model as well as the new Gen3 model.
Business Continuity/Disaster Recovery (BC/DR) Update: Lessons, Planning, Solutions
My colleague Vic Peltz from IBM Almaden presented on lessons learned from Hurricane Katrina and various other natural disasters. Unlike tradtional presentations the focus on technology, Vic took a different approach, focusing on people and procedures. I was here last year when the earthquake hit Christchurch on the south island, so I was well aware that BC/DR was top of mind for many of the attendees. Throughout this week, I have felt tremors, and many of the locals told me that these happen all the time.
Introduction to IBM Storwize V7000
I knew I was in trouble when the request for me to present Storwize sounded like something from [Mission Impossible]:
"Good morning, Mr. Pearson. Your mission, should you choose to accept it, involves presenting Storwize V7000 in Auckland, New Zealand. You may also present the Storwize V7000 Unified, but it is essential that you not cover the SAN Volume Controller or SONAS products from which they are based upon, as you will not have enough time. The audience is very technical, so be careful. As always, should any questions come up that you cannot answer, the conference coordinators will disavow all knowledge of your actions, nor reimburse your laundry charges. This message will self-destruct in five seconds."
Well, I accomplished my mission in 75 minutes. I was able to cover the block-only version of the IBM Storwize V7000, with support for clustering the control enclosures, expansion drawers and external storage virtualization. I then spent a few minutes on the block-and-file Storwize V7000 Unified, which adds support for CIFS, NFS, HTTPS, FTP and SCP protocols through two new "file modules", with integrated support for backup and anti-virus checking. I covered both IBM Easy Tier for sub-LUN automated tiering between Solid-State Drives (SSD) and spinning disk, as well as Active Cloud Engine for file-based movement between disk and tape.
Have you ever noticed that sometimes two movies come out that seem eerily similar to each other, released by different studios within months or weeks of each other? My sister used to review film scripts for a living, she would read ten of them and have to pick her top three favorites, and tells me that scripts for nearly identical concepts came all the time. Here are a few of my favorite examples:
1994: [Wyatt Earp] and [Tombstone] were Westerns recounting the famed gunfight at the O.K. Corral. Tombstone, Arizona is near Tucson, and the gunfight is recreated fairly often for tourists.
1998: [Armageddon] and [Deep Impact] were a pair of disaster movies dealing with a large rock heading to destroy all life on earth. I was in Mazatlan, Mexico to see the latter, dubbed in Spanish as "Impacto Profundo".
1998: [A Bug's Life] and [Antz] were computer-animated tales of the struggle of one individual ant in an ant colony.
2000: [Mission to Mars] and [Red Planet] were sci-fi pics exploring what a manned mission to our neighboring planet might entail.
This is different than copy-cat movies that are re-made or re-imagined many years later based on the previous successes of an original. Ever since my blog post [VPLEX: EMC's Latest Wheel is Round] in 2010 comparing EMC's copy-cat product that came our seven years after IBM's SAN Volume Controller (SVC), I've noticed EMC doesn't talk about VPLEX that much anymore.
This week, IBM announced [XIV Gen3 Solid-State Drive support] and our friends over at EMC announced [VFCache SSD-based PCIe cards]. Neither of these should be a surprise to anyone who follows the IT industry, as IBM had announced its XIV Gen3 as "SSD-Ready" last year specifically for this purpose, and EMC has been touting its "Project Lightning" since last May.
Fellow blogger Chuck Hollis from EMC has a blog post [VFCache means Very Fast Cache indeed] that provides additional detail. Chuck claims the VFCache is faster than popular [Fusion-IO PCIe cards] available for IBM servers. I haven't seen the performance spec sheets, but typically SSD is four to five times slower than the DRAM cache used in the XIV Gen3. The VFCache's SSD is probably similar in performance to the SSD supported in the IBM XIV Gen3, DS8000, DS5000, SVC, N series, and Storwize V7000 disk systems.
Nonetheless, I've been asked my opinions on the comparison between these two announcements, as they both deal with improving application performance through the use of Solid-State Drives as an added layer of read cache.
(FTC Disclosure: I am both a full-time employee and stockholder of the IBM Corporation. The U.S. Federal Trade Commission may consider this blog post as a paid celebrity endorsement of IBM servers and storage systems. This blog post is based on my interpretation and opinions of publicly-available information, as I have no hands-on access to any of these third-party PCIe cards. I have no financial interest in EMC, Fusion-IO, Texas Memory Systems, or any other third party vendor of PCIe cards designed to fit inside IBM servers, and I have not been paid by anyone to mention their name, brands or products on this blog post.)
The solutions are different in that IBM XIV Gen3 the SSD is "storage-side" in the external storage device, and EMC VFCache is "server-side" as a PCI Express [PCIe] card. Aside from that, both implement SSD as an additional read cache layer in front of spinning disk to boost performance. Neither is an industry first, as IBM has offered server-side SSD since 2007, and IBM and EMC have offered storage-side SSD in many of their other external storage devices. The use of SSD as read cache has already been available in IBM N series using [Performance Accelerator Module (PAM)] cards.
IBM has offered cooperative caching synergy between its servers and its storage arrays for some time now. The predecessor to today's POWER7-based were the iSeries i5 servers that used PCI-X IOP cards with cache to connect i5/OS applications to IBM's external disk and tape systems. To compete in this space, EMC created their own PCI-X cards to attach their own disk systems. In 2006, IBM did the right thing for our clients and fostered competition by entering in a [Landmark agreement] with EMC to [license the i5 interfaces]. Today, VIOS on IBM POWER systems allows a much broader choice of disk options for IBM i clients, including the IBM SVC, Storwize V7000 and XIV storage systems.
Can a little SSD really help performance? Yes! An IBM client running a [DB2 Universal Database] cluster across eight System x servers was able to replace an 800-drive EMC Symmetrix by putting eight SSD Fusion-IO cards in each server, for a total of 64 Solid-State drives, saving money and improving performance. DB2 has the Data Partitioning Feature that has multi-system DB2 configurations using a Grid-like architecture similar to how XIV is designed. Most IBM System x and BladeCenter servers support internal SSD storage options, and many offer PCIe slots for third-party SSD cards. Sadly, you can't do this with a VFCache card, since you can have only one VFCache card in each server, the data is unprotected, and only for ephemeral data like transaction logs or other temporary data. With multiple Fusion-IO cards in an IBM server, you can configure a RAID rank across the SSD, and use it for persistent storage like DB2 databases.
Here then is my side-by-side comparison:
IBM XIV Gen3 SSD Caching
Selected x86-based models of Cisco UCS, Dell PowerEdge, HP ProLiant DL, and IBM xSeries and System x servers
All of these, plus any other blade or rack-optimized server currently supported by XIV Gen3, including Oracle SPARC, HP Titanium, IBM POWER systems, and even IBM System z mainframes running Linux
Operating System support
Linux RHEL 5.6 and 5.7, VMware vSphere 4.1 and 5.0, and Windows 2008 x64 and R2.
All of these, plus all the other operating systems supported by XIV Gen3, including AIX, IBM i, Solaris, HP-UX, and Mac OS X
FCP and iSCSI
Vendor-supplied driver required on the server
Yes, the VFCache driver must be installed to use this feature.
No, IBM XIV Gen3 uses native OS-based multi-pathing drivers.
External disk storage systems required
None, it appears the VFCache has no direct interaction with the back-end disk array, so in theory the benefits are the same whether you use this VFCache card in front of EMC storage or IBM storage
XIV Gen3 is required, as the SSD slots are not available on older models of IBM XIV.
Shared disk support
No, VFCache has to be disabled and removed for vMotion to take place.
Yes! XIV Gen3 SSD caching shared disk supports VMware vMotion and Live Partition Mobility.
Support for multiple servers
An advantage of the XIV Gen3 SSD caching approach is that the cache can be dynamically allocated to the busiest data from any server or servers.
Support for active/active server clusters
Aware of changes made to back-end disk
No, it appears the VFCache has no direct interaction with the back-end disk array, so any changes to the data on the box itself are not communicated back to the VFCache card itself to invalidate the cache contents.
None identified. However, VFCache only caches blocks 64KB or smaller, so any sequential processing with larger blocks will bypass the VFCache.
Yes! XIV algorithms detect sequential access and avoid polluting the SSD with these blocks of data.
Number of SSD supported
One, which seems odd as IBM supports multiple Fusion-IO cards for its servers. However, this is not really a single point of failure (SPOF) as an application experiencing a VFCache failure merely drops down to external disk array speed, no data is lost since it is only read cache.
6 to 15 (one per XIV module) for high availability.
Pin data in SSD cache
Yes, using split-card mode, you can designate a portion of the 300GB to serve as Direct-attached storage (DAS). All data written to the DAS portion will be kept in SSD. However, since only one card is supported per server and the data is unprotected, this should only be used for ephemeral data like logs and temp files.
No, there is no option to designate an XIV Gen3 volume to be SSD-only. Consider using Fusion-IO PCIe card as a DAS alternative, or another IBM storage system for that requirement.
Pre-sales Estimating tools
Yes! CDF and Disk Magic tools are available to help cost-justify the purchase of SSD based on workload performance analysis.
IBM has the advantage that it designs and manufactures both servers and storage, and can design optimal solutions for our clients in that regard.
By combining multiple components into a single "integrated system", IBM can offer a blended disk-and-tape storage solutions. This provides the best of both worlds, high speed access using disk, while providing lower costs and more energy efficiency with tape. According to a study by the Clipper Group, tape can be 23 times less expensive than disk over a 5 year total cost of ownership (TCO).
I've also covered Hierarchical Storage Management, such as my post [Seven Tiers of Storage at ABN Amro], and my role as lead architect for DFSMS on z/OS in general, and DFSMShsm in particular.
However, some explanation might be warranted in the use of these two terms in regards to SONAS. In this case, ILM refers to policy-based file placement, movement and expiration on internal disk pools. This is actually a GPFS feature that has existed for some time, and was tested to work in this new configuration. Files can be individually placed on either SAS (15K RPM) or SATA (7200 RPM) drives. Policies can be written to move them from SAS to SATA based on size, age and days non-referenced.
HSM is also a form of ILM, in that it moves data from SONAS disk to external storage pools managed by IBM Tivoli Storage Manager. A small stub is left behind in the GPFS file system indicating the file has been "migrated". Any reference to read or update this file will cause the file to be "recalled" back from TSM to SONAS for processing. The external storage pools can be disk, tape or any other media supported by TSM. Some estimate that as much as 60 to 80 percent of files on NAS have low reference and should be stored on tape instead of disk, and now SONAS with HSM makes that possible.
This distinction allows the ILM movement to be done internally, within GPFS, and the HSM movement to be done externally, via TSM. Both ILM and HSM movement take advantage of the GPFS high-speed policy engine, which can process 10 million files per node, run in parallel across all interface nodes. Note that TSM is not required for ILM movement. In effect, SONAS brings the policy-based management features of DFSMS for z/OS mainframe to all the rest of the operating systems that access SONAS.
HTTP and NIS support
In addition to NFS v2, NFS v3, and CIFS, the SONAS v1.1.1 adds the HTTP protocol. Over time, IBM plans to add more protocols in subsequent releases. Let me know which protocols you are interested in, so I can pass that along to the architects designing future releases!
SONAS v1.1.1 also adds support for Network Information Service (NIS), a client/server based model for user administration. In SONAS, NIS is used for netgroup and ID mapping only. Authentication is done via Active Directory, LDAP or Samba PDC.
SONAS already had synchronous replication, which was limited in distance. Now, SONAS v1.1.1 provides asynchronous replication, using rsync, at the file level. This is done over Wide Area Network (WAN) across to any other SONAS at any distance.
Interface modules can now be configured with either 64GB or 128GB of cache. Storage now supports both 450GB and 600GB SAS (15K RPM) and both 1TB and 2TB SATA (7200 RPM) drives. However, at this time, an entire 60-drive drawer must be either all one type of SAS or all one type of SATA. I have been pushing the architects to allow each 10-pack RAID rank to be independently selectable. For now, a storage pod can have 240 drives, 60 drives of each type of disk, to provide four different tiers of storage. You can have up to 30 storage pods per SONAS, for a total of 7200 drives.
An alternative to internal drawers of disk is a new "Gateway" iRPQ that allows the two storage nodes of a SONAS storage pod to connect via Fibre Channel to one or two XIV disk systems. You cannot mix and match, a storage pod is either all internal disk, or all external XIV. A SONAS gateway combined with external XIV is referred to as a "Smart Business Storage Cloud" (SBSC), which can be configured off premises and managed by third-party personnel so your IT staff can focus on other things.
See the Announcement Letters for the SONAS [hardware] and [software] for more details.
For those who are wondering how this positions against IBM's other NAS solution, the IBM System Storage N series, the rule of thumb is simple. If your capacity needs can be satisfied with a single N series box per location, use that. If not, consider SONAS instead. For those with non-IBM NAS filers that realize now that SONAS is a better approach, IBM offers migration services.
Both the Information Archive and the SONAS can be accessed from z/OS or Linux on System z mainframe, from "IBM i", AIX and Linux on POWER systems, all x86-based operating systems that run on System x servers, as well as any non-IBM server that has a supported NAS client.
My colleagues, Harley Puckett (left) and Jack Arnold (right) were highlighted in today's Arizona Daily Star, our local newspaper, as part of an article on IBM's success and leadership in the IT storage industry. At 1400 employees here in Tucson, IBM is Southern Arizona's 36th largest employer.
Highlighted in the article:
DS8700 with the new Easy Tier feature
TS7650 ProtecTIER virtual tape library with data deduplication capability
LTO-5 tape and the new Long Term File System (LTFS)
XIV with the new 2TB drive, for a maximum per-rack usable capacity of 161 TB.
Well, it's Tuesday again, and that means IBM announcements! Right on the heels of our big storage launch on February 9, today IBM announced some exciting options for its modular disk systems. Let's take a look:
2TB SATA-II drives
That's right, you can now DOUBLE your capacity with 2TB SATA type-II drives on the DS3950, DS4200, DS4700, DS5020, DS5100 and DS5300 disk controllers, as well as the DS4000 EXP420, EXP520, EXP810, EXP5000 and EXP5060 expansion drawers. Here are the Announcement Letters for the [HVEC] and [AAS] ordering systems.
300GB Solid State Drives
IBM also announces 300GB solid state drives (SSD) for the DS5100 and DS5300. These are four times larger than the 73GB drives IBM offered last year, for those workloads that need high read IOPS such as Online Transaction Processing (OLTP) and Enterprise Resource Planning (ERP) applications. Here is the [Announcement Letter].
New N series model N3400
For customers that need less than the minimum 21TB that our IBM Scale-Out Network Attach Storage (SONAS) can provide, IBM offers the new N3400 unified storage disk system, with support for NFS, CIFS, iSCSI and FCP. This is a 2U high 12 drive model that can be expanded up to 136 drives, basically doubling all the stats from last year's N3300 model. Fellow blogger, Rich Swain (IBM), does a great job recapping the speeds and feeds over on his blog [News and Information about IBM N series].
It also appears that the reports and rumors of the death of the DS6800 are premature. Don't believe misleading statements from competitors, such as those found written by fellow blogger BarryB (EMC), aka "the Storage Anarchist", in his latest post [Bring Out Your Dead] showing a cute little tombstone with "Feb 2010" on the bottom. Actually, if he had bothered to read IBM's [Announcement Letter], he would have realized that IBM plans to continue to sell these until June. Of course, IBM will continue to support both new and existing DS6800 customers for many years to come.
Technically, BarryB does not make any factually incorrect statements for me to correct on his blog. The idea that a product is "dead" is, of course, just opinion, and competitors poke fun at each others' announcements every day. One could argue that the EMC V-Max was "dead" after the ITG whitepaper [Cost/Benefit Case for IBM XIV Storage System - Comparing Costs for IBM XIV and EMC V-Max Systems] demonstrated that the IBM XIV cost 63 percent less than a comparable EMC V-Max over the life of three years total cost of ownership (TCO) back in July 2009. The comparison was made with data from clients in a variety of industries including manufacturing, health care, life sciences, telecommunications, financial services, and the public sector. This could explain why so many EMC customers are buying or investigating the IBM XIV and the rest of the IBM storage portfolio.
Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
5465-028 Standard SAN Volume Controller
5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!
This week, IBM made over a dozen announcements related to IBM storage products. Here is part 2 of my overview:
IBM System Storage® DS8000 series microcode
One of the advantages of acquiring XIV as IBM's other high-end disk system, is that it allows the DS8000 team to focus on the IBM i and z/OS operating systems. As a result, IBM DS8000 has over half the mainframe-attach market share.
For both the DS8700 and DS8800 models, IBM Easy Tier now support sub-LUN automated tiering across three storage tiers: Solid-State Drives, high-performance spinning disk drives (15K and 10K RPM), and high-capacity disk drives (7200 RPM).
For System z customers, the latest DS8000 microcode has synergy with z/OS and GDPS, now supporting 4x larger EAV volumes, faster high-performance FICON (zHPF), and Workload Manager (WLM) integration with the I/O Priority Manager. IBM has a world record SAP performance of 59 million account postings per hour. DB2 v10 for z/OS queries were measured at 11x faster using the new zHPF feature.
IBM System Storage® DS8800 systems
On the hardware side, the DS8800 now supports a fourth frame to hold a total over 1,500 disk drives. Yes, we have customers that three frames wasn't enough, and they wanted more.
IBM is now also offering new drive options. Small Form Factor (2.5 inch) drives now include 300GB 15K RPM drives, and a 900GB 10K RPM drives. But wait! There's more! The DS8800 is no longer a SFF-only box, it now allows for mixing in Large form factor (3.5 inch) drives, starting with the 3TB NL-SAS 7200 RPM drive.
IBM XIV® Storage System Gen3
We announced the XIV Gen3 already, but we have two enhancements.
First, we now offer a model based entirely on 3TB NL-SAS drives. If you are thinking, what IBM is going to put 3TB drives into everything? Yup. Once we go through all the pain and suffering of qualifying a drive, we make sure we get our money's worth!
Secondly, we have now an iPad application to manage the XIV. This has nothing to do with Apple CEO Steve Jobs passing away last week, it was merely coincidence.
IBM Real-time Compression Appliances™ STN6500 and STN6800 V3.8
The latest software for RtCA now supports Microsoft SMB v2, and enhanced reporting so that storage admins know exactly the benefits of the compression ratios of different file extensions.
IBM System Storage EXP2500 Express®
The EXP2500 is for direct-attach situations, like the IBM BladeCenter. IBM adds LFF 3.5-inch 3TB NL-SAS drives, SFF 2.5-inch 300GB 15K RPM SAS drives, and 900GB 7200 RPM NL-SAS drives.
My colleague Curtis Neal refers to these as "B.F.D" announcements, which of course stands for Bigger, Faster, Denser!
