The "Basic" offering includes a single IBM Storwize V7000 controller enclosure, and three year warranty package that includes software licenses for IBM Tivoli Storage FlashCopy Manager (FCM) and IBM Tivoli Storage Productivity Center for Disk - Midrange Edition (MRE). Planning, configuration and testing services for the software are included and can be performed by either IBM or an IBM Business Partner.
The "Standard" offering allows for multiple IBM Storwize V7000 enclosures, provides three year warranty package for the FCM and MRE software, and includes implementation services for both the hardware and the software components. These services can be performed by IBM or an IBM Business Partner.
Why bundle? Here are the key advantages for these offerings:
Increased storage utilization! First introduced in 2003, IBM SAN Volume Controller is able to improve storage utilization by 30 percent through virtualization and thin provisioning. IBM Storwize V7000 carries on this tradition. Space-efficient FlashCopy is included in this bundle at no additional charge and can reduce the amount of storage normally required for snapshots by 75 percent or more. IBM Tivoli Storage FlashCopy Manager can manage these FlashCopy targets easily.
Improved storage administrator productivity! The new IBM Storwize V7000 Graphical User Interface can help improve administrator productivity up to 2 times compared to other midrange disk solutions. The IBM Tivoli Storage Productivity Center for Disk - Midrange Edition provides real-time performance monitoring for faster analysis time.
Increased application performance! This bundle includes the "Easy Tier" feature at no additional charge. Easy Tier is IBM's implementation of sub-LUN automated tiering between Solid-State Drives (SSD) and spinning disk. Easy Tier can help improve application throughput up to 3 times, and improve response time up to 60 percent. Easy Tier can help meet or exceed application performance levels with its internal "hot spot" analytics.
Increased application availability! IBM Tivoli Storage FlashCopy Manager provides easy integration with existing applications like SAP, Microsoft Exchange, IBM DB2, Oracle, and Microsoft SQL Server. Reduce application downtime to just seconds with backups and restores using FlashCopy. The built-in online migration feature, included at no additional charge, allows you to seamlessly migrate data from your old disk to the new IBM Storwize V7000.
Significantly reduced implementation time! This bundle will help you cut implementation time in half, with little or no impact to storage administrator staff. This will help you realize your return on investment (ROI) much sooner.
Continuing coverage of my week in Washington DC for the annual [2010 System Storage Technical University], I attended several XIV sessions throughout the week. There were many XIV sessions. I could not attend all of them. Jack Arnold, one of my colleagues at the IBM Tucson Executive Briefing Center, often presents XIV to clients and Business Partners. He covered all the basics of XIV architecture, configuration, and features like snapshots and migration. Carlos Lizarralde presented "Solving VMware Challenges with XIV". Ola Mayer presented "XIV Active Data Migration and Disaster Recovery".
Here is my quick recap of two in particular that I attended:
XIV Client Success Stories - Randy Arseneau
Randy reported that IBM had its best quarter ever for the XIV, reflecting an unexpected surge shortly after my blog post debunking the DDF myth last April. He presented successful case studies of client deployments. Many followed a familiar pattern. First, the client would only purchase one or two XIV units. Second, the client would beat the crap out of them, putting all kinds of stress from different workloads. Third, the client would discover that the XIV is really as amazing as IBM and IBM Business Partners have told them. Finally, in the fourth phase, the client would deploy the XIV for mission-critical production applications.
A large US bank holding company managed to get 5.3 GB/sec from a pair of XIV boxes for their analytics environment. They now have 14 XIV boxes deployed in mission-critical applications.
A large equipment manufacturer compared the offerings among seven different storage vendors, and IBM XIV came out the winner. They now have 11 XIV boxes in production and another four boxes for development/test. They have moved their entire VMware infrastructure to IBM XIV, running over 12,000 guest instances.
A financial services company bought their first XIV in early 2009 and now has 34 XIV units in production attached to a variety of Windows, Solaris, AIX, Linux servers and VMware hosts. Their entire Microsoft Exchange was moved from HP and EMC disk to IBM XIV, and experienced noticeable performance improvement.
When a University health system replaced two competitive disk systems with XIV, their data center temperature dropped from 74 to 68 degrees Fahrenheit. In general, XIV systems are 20 to 30 percent more energy efficient per usable TB than traditional disk systems.
A service provider that had used EMC disk systems for over 10 years evaluated the IBM XIV versus upgrading to EMC V-Max. The three year total cost of ownership (TCO) of EMC's V-Max was $7 Million US dollars higher, so EMC counter-proposed CLARiiON CX4 instead. But, in the end, IBM XIV proved to be the better fit, and now the customer is happy having made the switch.
The manager of an information communications technology service provider was impressed that the XIV was up and running in just a couple of days. They now have over two dozen XIV systems.
Another XIV client had lost all of their Computer Room Air Conditioning (CRAC) units for several hours. The data center heated up to 126 degrees Fahrenheit, but the customer did not lose any data on either of their two XIV boxes, which continued to run in these extreme conditions.
Optimizing XIV Performance - Brian Cormody
This session was an update from the [one presented last year] by Izhar Sharon. Brian presented various best practices for optimizing the performance when using specific application workloads with IBM XIV disk systems.
Oracle ASM: Many people allocate lots of small LUNs, because this made sense a long time ago when all you had was just a bunch of disks (JBOD). In fact, many of the practices that DBAs use to configure databases across disks become unnecessary with XIV. Wth XIV, you are better off allocating a few number of very large LUNs from the XIV. The best option was a 1-volume ASM pool with 8MB AU stripe. A single LUN can contain multiple Oracle databases. A single LUN can be used to store all of the logs.
VMware: Over 70 percent of XIV customers use it with VMware. For VMFS, IBM recommends allocating a few number of large LUNs. You can specify the maximum of 2181 GB. Do not use VMware's internal LUN extension capability, as IBM XIV already has thin provisioning and works better to allow XIV to do this for you. XIV Snapshots provide crash-consistent copies without all the VMware overhead of VMware Snapshots.
SAP: For planning purposes, the "SAPS" unit equates roughly to 0.4 IOPS for ERP OLTP workloads, and 0.6 IOPS for BW/BI OLAP workloads. In general, an XIV can deliver 25-30,000 IOPS at 10-15 msec response time, and 60,000 IOPS at 30 msec response time. With SAP, our clients have managed to get 60,000 IOPS at less than 15 msec.
Microsoft Exchange: Even my friends in Redmond could not believe how awesome XIV was during ESRP testing. Five Exchange 2010 servers connected two a pair of XIV boxes using the new 2TB drawers managed 40,000 mailboxes at the high profile (0.15 IOPS per mailbox). Another client found four XIV boxes (720 drives) was able to handle 60,000 mailboxes (5GB max), which would have taken over 4000 drives if internal disk drives were used instead. Who said SANs are obsolete for MS Exchange?
Asynchronous Replication: IBM now has an "Async Calculator" to model and help design an XIV async replication solution. In general, dark fiber works best, and MPLS clouds had the worst results. The latest 10.2.2 microcode for the IBM XIV can now handle 10 Mbps at less than 250 msec roundtrip. During the initial sync between locations, IBM recommends setting the "schedule=never" to consume as much bandwidth as possible. If you don't trust the bandwidth measurements your telco provider is reporting, consider testing the bandwidth yourself with [iPerf] open source tool.
Well, it feels like Tuesday and you know what that means... "IBM Announcement Day!" Actually, today is Wednesday, but since Monday was Memorial Day holiday here in the USA, my week is day-shifted. Yesterday, IBM announced its latest IBM FlashCopy Manager v2.2 release. Fellow blogger, Del Hoobler (IBM) has also posted something on this out atthe [Tivoli Storage Blog].
IBM FlashCopy Manager replaces two previous products. One was called Tivoli Storage Manager for Copy Services, the other was called Tivoli Storage Manager for Advanced Copy Services. To say people were confused between these two was an understatement, the first was for Windows, and the second was for UNIX and Linux operating systems. The solution? A new product that replaces both of these former products to support Windows, UNIX and Linux! Thus, IBM FlashCopy Manager was born. I introduced this product back in 2009 in my post [New DS8700 and other announcements].
IBM Tivoli Storage FlashCopy Manager provides what most people with "N series SnapManager envy" are looking for: application-aware point-in-time copies. This product takes advantage of the underlying point-in-time interfaces available on various disk storage systems:
FlashCopy on the DS8000 and SAN Volume Controller (SVC)
Snapshot on the XIV storage system
Volume Shadow Copy Services (VSS) interface on the DS3000, DS4000, DS5000 and non-IBM gear that supports this Microsoft Windows protocol
For Windows, IBM FlashCopy Manager can coordinate the backup of Microsoft Exchange and SQL Server. The new version 2.2 adds support for Exchange 2010 and SQL Server 2008 R2. This includes the ability to recover an individual mailbox or mail item from an Exchange backup. The data can be recovered directly to an Exchange server, or to a PST file.
For UNIX and Linux, IBM FlashCopy Manager can coordinate the backup of DB2, SAP and Oracle databases. Version 2.2 adds support specific Linux and Solaris operating systems, and provides a new capability for database cloning. Basically, database cloning restores a database under a new name with all the appropriate changes to allow its use for other purposes, like development, test or education training. A new "fcmcli" command line interface allows IBM FlashCopy Manager to be used for custom applications or file systems.
A common misperception is that IBM FlashCopy Manager requires IBM Tivoli Storage Manager backup software to function. That is not true. You have two options:
In Stand-alone mode, it's just you, the application, IBM FlashCopy Manager and your disk system. IBM FlashCopy Manager coordinates the point-in-time copies, maintains the correct number of versions, and allows you to backup and restore directly disk-to-disk.
Unified Recovery Management with Tivoli Storage Manager
Of course, the risk with relying only on point-in-time copies is that in most cases, they are on the same disk system as the original data. The exception being virtual disks from the SAN Volume Controller. IBM FlashCopy Manager can be combined with IBM Tivoli Storage Manager so that the point-in-time copies can be copied off to a local or remote TSM server, so that if the disk system that contains both the source and the point-in-time copies fails, you have a backup copy from TSM. In this approach, you can still restore from the point-in-time copies, but you can also restore from the TSM backups as well.
IBM FlashCopy Manager is an excellent platform to connect application-aware fucntionality with hardware-based copy services.

It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
Simultaneous Background Tasks
The TSM server has many background administrative tasks:
Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.
