Well, it's Tuesday, so that means IBM announcements!
We had so much announced, that I will just cover the disk systems today, and deal with tape systems and software tomorrow.
- IBM System Storage DS8000 series
IBM continues to invest heavily in its strategic [DS8000 series].For [existing 2107 machines], IBM's new DS8000 microcode supports:
- 1 TB 7200 rpm Serial ATA (SATA) Disk Drives
Now that IBM XIV has proven that 1TB SATA are safe for high-end tier-1 enterprise class use, we extended DS8000 support to include SATA support also. DS8000 supports RAID-6 and RAID-10 for these.
- Intelligent Write Caching
IBM Research conducts extensive investigations into improved algorithms for cache management. Intelligent Write Caching boosts performance for both temporal and spatial locality.
- Remote Pair FlashCopy®
This allows you to FlashCopy volume A to volume B, with Volume B remotely mirrored to Volume C at a secondary location, via Metro Mirror. This allows you to have a consistent copy of your data at both locations.
For[newly ordered 242x models], you get all the features above, plus the following additional support:
- Full Disk Encryption (FDE)
IBM was the first in the industry to deliver tape-drive encryption, so it makes sense that IBM is also the first in the industry to deliver disk-drive encryption. These are 15K rpm drives in standard 146GB, 300GB and 450GB capacities. As with tape, encrypting at the disk device eliminates the huge overhead from server-based encryption methods.
- Solid State Drive (SSD)
You can also have Solid State Disk drives in your DS8000, in 73GB and 146GB capacities, protected by RAID-5.If you are wondering what data to put on these much-faster drives, IBM has taken the work and worry out by havingintelligence in DB2 to optimize what gets placed on SSD to get the most performance improvement.
- IBM System Storage XIV
Continuing the incredible marketplace excitement over its Cloud-Opimized Storage[XIV series], IBM now has announced[new capacity options]. The IBM XIV R2 that we announced last August 2008 was a fixed 15 module configuration. In thenew configurations, you can start with as little as six modules, representing a 40% partial rack of the originalfull model. Here is a table that shows the details:
|Total Modules|| 6 || 9 || 10 || 11 || 12 || 13 ||14 || 15|
| Useable Capacity (TB) ||27 || 43 || 50 || 54 || 61 || 66 || 73 || 79|
|Interface Modules ||3 || 6 || 6 || 6 || 6 || 6 || 6 || 6|
|Data Modules ||3 || 3 || 4 || 5 || 6 || 7 || 8 || 9|
|Disk Drives ||72 || 108 || 120 || 132 || 144 || 156 || 168 || 180|
|Fibre Channel Ports ||8 || 16 || 16 || 20 || 20 || 24 || 24 || 24|
|iSCSI Ports ||0 || 4 || 4 || 6 || 6 || 6 || 6 || 6|
|Cache Memory (GB) ||48 || 72 || 80 || 88 || 96 || 104 || 112 || 120|
- IBM System Storage N series
And last, but not least, we have two new models in IBM's[N6000 series].The [N6060]has model A12 (single controller) and model A22 (dual controller). These are disk-less controllers thatyou can configure in either appliance mode or gateway mode. In appliance mode, you can attachdisk drawers such as the EXN1000, EXN2000 or EXN4000. In gateway mode, you attach external disk systems, suchas the IBM DS8000 or XIV above.
Also, IBM introduces the new [2101 model N42 rack], which has the following features:
- It's ruggedized to handle earthquakes. IBM brings a feature that we've had for a while on other disk systems to the N series with a collection of bolts and anchors to secure the rack from physical tremors.
- It's instrumented for IBM Active Energy Manager, a component of IBM Systems Director. New iPDUs are designed to help measure and monitor energy management components. As companies get more concerned about thefate of the planet, monitoring energy consumption can help reduce carbon footprint.
I'll cover the rest of the announcements tomorrow!

Well, it's Tuesday again, and that means more IBM announcements!
Today, IBM announced the enhanced IBM System Storage DS3200 disk system.It is in our DS3000 series, the DS3200 is SAS-attach, DS3300 is iSCSI-attach, and DS3400 is FC-attach. All of them support up to 48 drives, which can be a mix of SAS and SATA drives.
The DS3200 supports the following operating environments (see IBM's [Interop Matrix] for details):
- Microsoft Windows
- Linux (both Linux-x86 and Linux on POWER)
- Sun Solaris
- Novell NetWare
With today's announcements, the DS3200 can be used to boot from, as well as contain data. This is ideal to combine with IBM BladeCenter. With the IBM BladeCenter you can have 14 blades, either x86 or POWER based processors, attached to a DS3200 via SAS switch modules in the back of the chassis.
Let's take an example of how this can be used for a Scale-Out File Services[SoFS] deployment.
First, we start with servers. We can have either three [IBM System x3650] servers, but this would use up all six of the direct-attach ports. Instead, we'll choose the [BladeCenter H chassis], with three HS21 blades for SoFS, and that leaves us with eleven empty blade slots we could put in a management node, or other blades to run applications.
- SAS connectivity modules
The IBM BladeCenter [SAS Connectivity Module] allows the blade servers to connect to a DS3200. Two of them fit right in the back of the BladeCenter chassis, providing full redundancy without consuming additional rack space.
- DS3200 and EXP3000 expansion drawers
We'll have one DS3200 controller with twelve internal drives, and three expansion EXP3000 drawers with twelve drives each, for a total of 48 drives. Using 1TB SATA, this would be 48 TB raw capacity.
The end result? You get a 48TB NAS scalable storage solution, supporting up to 7500 concurrent CIFS and NFS users, with up to 700 MB/sec with large block transfers. By using BladeCenter, you can expand performance by adding more blades to the Chassis, or have some blades running SAP or Oracle RAC have direct read/write access to the SoFS data.
Just another example on how IBM can bring together all the components of a solution to provide customer value!

In case you haven't noticed, IBM System Storage makes most of their announcements on Tuesdays. IBM announced a lot today, so here is a quick run-down.
- Cisco storage networking products
IBM continues to resell Cisco switches and directors, but now can offer these with a 1-year IBM warranty.
The entry-level Cisco 9124offers 8 to 24 ports. For IBM BladeCenter, IBM now offers the Cisco10-port and 20-port modules that slide into the back of the chassis, and are functionally equivalent to the 9124.The original BladeCenter came with a 16-port module with 14 internal, but only 2 external, which severely hamperedbandwidth connectivity to external storage. These new modules provide more external ports to relieve that constraint.
The midrange Cisco9200switches have two models, both with 16 fixed ports, with the option for a blade that can provide 12, 24 or 48 additional ports. The 9216A has 16 FCP ports, and the 9216i has 14 FCP ports, and 2 GbE ports to act as a router, such as toconnect to a remote location for business continuity using Metro Mirror or Global Mirror.
The enterprise-class Cisco 9500directors can support up to 528 ports.
- TS3400 Tape Library
The new TS3400library is a small entry-level size library, supporting the enterprise-class TS1120 drive, providing interoperabilitywith the larger tape libraries, with all the support for tape encryption.
In addition to Linux, Unix, and WIndows, the TS1120 can now be connected to System i servers. In the past, the only IBMtape available to System i were the LTO models. There are a lot of businesses that need to comply with government regulations that are looking for tape encryption, and now IBM has made it accessible to more clients.
- 300GB drives at 15K RPM
The DS8000 can now support new drives with 300GB capacity at 15,000 RPM (15K). These can be up to 30 percent faster than the 10,000 RPM drives for typical workloads.
IBM continues its market leadership with these new set of features and offerings!

Normally, IBM only makes announcements on Tuesdays, but today, Friday, IBM announces that it acquired Diligent Technologies. What? I got a lot ofquestions about this, so I thought I would start with this...
When I posted in January that[IBM Acquires XIV],fellow EMC blogger Mark Twomey of StorageZilla fame, sent me a comment:
"Ah now Tony I wasn't poking fun. Indeed I find it fascinating that Moshe who's been sitting out on the fringes for years having been banished for being an obstructionist to EMC entering the mid-market is now back.
Which reminds me what happens with Diligent? There his as well aren't they or has he packed his stake in that in?"
As you might have guessed, I am privy to a lot of stuff going on behind the scenes at IBM that I can't talk about in this blog, and all these rumors in the blogosphere about IBM acquisition of Diligent was a topic I couldn't officially recognize, defend or deny, until official IBM announcements were made.
In his latest post, Mark wonders about[the last Tape and Mainframe sales person on earth]. He recounts my interaction with fellow HDS blogger Hu Yoshia about the energy benefits ofVirtual Tape Libraries. Knowing that we were going to announcement IBM's acquisition of Diligent soon, I thoughtthis would be a worthy exchange, driving up the sales of Diligent boxes (whether you buy them from IBM or HDS).Diligent already had reselling arrangements with HDS, and IBM plans to continue thosearrangements going forward with HDS. As I have explained before in my post [Supermarketsand Specialty Shops], IBM and HDS cater to different customers, so if a customer who wants the best technologyfrom a specialty shop, they can buy IBM Diligent products from HDS, but if they want one-stop shopping, they can buyIBM Diligent directly from IBM or its other IBM Business Partners.
(Perhaps a more tricky situation is that Diligent also had an arrangement with Sun Microsystems, which competesdirectly against IBM as another IT supermarket vendor, but I have not heard how IBM has decided to handle thisgoing forward.)
For more on this intricate mess of interconnected companies, alliances and partnerships, read Dave Raffo's article[Data dedupe dance cardfilling up] over at Storage Soup.
So, let's tackle the first question:
- Q1. What will happen to IBM's real tape library business?
Come on! IBM is Number one in tape, we've had virtual tape libraries since 1997 (the first in the industry)and continue to do well in both virtual and real tape libraries. Both provide value to the customer, and bothhave their place as part of the overall "information infrastructure". This acquisition provides yet another choicefor clients on our "supermarket" shelf.
(For those following the ["which is greener"] discussion, the robot of the IBM TS3500 real tape library consumes185W per frame (when moving) and each tape drive consumes 50W (when actively working on a tape). Compared to 13W per SATA disk drive, each 6-drive frame of a TS3500 consumes as much electricity as 37 SATA disk drives. If you are not running backups 24x7, the total KWh per day for your tape library is actually quite less, but as several people have pointed out, there are customers that do run backups 80-90 percent of the time. LTO-4 tapes can hold 800GB uncompressed, and SATA disk are now available in 1TB (1000 GB) size, so you can have fun with your own comparisons.)
Meanwhile, Scott Waterhouse, one of the few people at EMC who understand tape workloadslike backup and archive, takes me to task in his Backup Blog
with his post[I want a Red Ferrari
].For those who are surprised that anyone at EMC might understand backup workloads, EMC did acquire a company calledLegato, and perhaps Scott came from that acquisition. I've never met Scott in person, but based solely only fromhis writings, he seems to know his stuff and makes strong arguments for using IBM Tivoli Storage Manager (TSM) with deduplication and virtual tape libraries.
While TSM does a good job of "deduplicating" at the client first, backing up only changed data, Scott feels database and email repositories must be backed up entirely each time, which is what happens in many other backup software products. Some clients might have 80 percent database/email and only 20 percent files, while others might have less than 20 percent database/email and 80 percent files, so this might influence whether deduplication will have small or big benefit.If TSM has to backup the entire database, even though little has changed since the last backup, that is where deduplication on a virtual tape library can come in handy. For IBM DB2 and Oracle databases, IBM TSM application-aware Tivoli Data Protection module interface backs up only changed data, not the entire file. Thanks to IBM's FilesX acquisition-- (also coincidently from Israel) --IBM can extend this support now to SQL Server databases as well.However, to be fair, Scott is partly correct, TSM does backup some database and email repositories in their entirety, which is why it is a good idea to have BOTH an IBM virtual tape library with deduplication and Tivoli Storage Manager to handle all cases. This brings us to the next question:
- Q2. What will happen to IBM's patented "progressive backup" technology?
IBM will continue to use TSM's progressive backup technology. TSM already works great with Diligent virtual tapelibraries. One example is LAN-free backup. In this configuration, the TSM client writes its backups directly toa virtual or real tape library, over the SAN, and then sends the list of files backed up to the TSM server over theLAN to record in its database. This can greatly reduce IP traffic on your LAN during peak backup periods. For more about this, see the IBM Redbook titled["Get More Out of Your SAN with IBM Tivoli Storage Manager"].
Jon Toigo from DrunkenData asks[Did IBM Do Due Diligence Before Making Diligent Acquisition a Done Deal?] which is probably always a valid question. Unlike XIV, I wasn't part of the Diligent acquisition team, so I can't provide first hand account of the process. I am told that the IBM team did all the right things to make sure everything is going to turn out right.Sadly, many companies that make acquisitions in the IT industry fail to make them work. Fortunately, IBM is one of the few companies that has a great success record, with over 60 acquisitions in the past six years.In the Xconomy forum, Wade Rousch writes[IBM and the Art of Acquisitions]and gives some insight why IBM is different. Jon did not understand why Cindy Grossman, IBM VP of tape and archive solutions, ran the analyst conference call for this announcement, which brings me to the next question:
- Q3. What is Diligent virtual tape library going to be categorized as, a disk system or a tape system?
IBM organizes its storage systems based on the host application workloads.Products to address disk workloads (SVC, DS8000 series, DS6000 series, DS4000 series, DS3000 series, N series, XIV Nextra) are in our disk systems group. Storage that appears to host applications like a tape system to address workloads like backup and archive (tape drives, libraries and tape virtualization) are in our tape and archive group. IBM Diligent has two products, one for big workloads and one for medium workloads. Both look liketape systems, so our tape and archive team, who understand tape workloads like backup and archive the best, are obviously the best choice to support IBM Diligent in the mix.
Some might remember that IBM already has deduplication in its IBM N series products, called Advanced Single InstanceStorage, or A-SIS. Here is an[IBM System Storage N Series A-SIS Deduplication Deployment and Implementation Guide. This brings up the fourth question:
- Q4. What will happen to N series A-SIS feature?
IBM will offer both N series and Diligent deduplication capabilities. For disk workloads, IBM N series offers a post-process deduplication feature at no additional charge. For tape workloads, IBM will now offer an in-line deduplication feature with Diligent Technologies. Different workloads, different offerings.
As with any acquisition, there will be some changes. The 100 folks from Diligent will get to learn the IBM wayof doing things. This brings me to our fifth and final question:
- Q5. What is the correct spelling: deduplication or de-duplication?
It appears that Diligent has a corporate-wide standard to hyphenate this term (de-duplication), but the "word police" at IBM that control and standardize all "proper spellings, trademarks, and capitalization" have sent me corporate instructions a few days ago that IBM does not to hyphenate this term (deduplication). So, going forward, it will be "deduplication", or "dedupe" for short.I suspect one of the first tasks that our new IBMers from Diligent will be doing is removing all those hyphens fromthe [Diligent Technologies website]!
That's all for now, I'm off to Chicago, Illinois tomorrow!

So here we are in January, named after the two-faced Roman god Janus, who in their mythology was the god of gates and doors, and beginnings and endings.
-- Roger von Oech[Our "Janus-Like" Powers]
Well, it's 2008, which could mark the end to RAID5 and mark the beginnings of a new disk storagearchitecture. IBM starts the year with exciting news, acquiring new disk technology from a smallstart-up called XIV, led by former-EMCer Moshe Yanai. Moshe was ousted publicly in 2001 from hisposition as EMC's VP of engineering, and formed his own company. It didn't take long for EMC bloggersto poke fun at this already. Mark Twomey, in his StorageZilla blog, had mentioned XIV before back in August,[XIV], and again todayin [IBM Buys XIV].
The following is an excerpt from the [IBM Press Release]:
To address the new requirements associated with next generation digital content, IBM chose XIV and its NEXTRA™ architecture for its ability to scale dynamically, heal itself in the event of failure, and self-tune for optimum performance, all while eliminating the significant management burden typically associated with rapid growth environments. The architecture also is designed to automatically optimize resource utilization of all the components within the system, which can allow for easier management and configuration and improved performance and data availability.
"We are pleased to become a significant part of the IBM family, allowing for our unique storage architecture, our engineers and our storage industry experience to be part of IBM's overall storage business," said Moshe Yanai, chairman, XIV. "We believe the level of technological innovation achieved by our development team is unparalleled in the storage industry. Combining our storage architectural advancements with IBM's world-wide research, sales, service, manufacturing, and distribution capabilities will provide us with the ability to have these technologies tackle the emerging Web 2.0 technology needs and reach every corner of the world."
The NEXTRA architecture has been in production for more than two years, with more than four petabytes of capacity being used by customers today.
Current disk arrays were designed for online transaction processing (OLTP) databases. The focus was onusing fastest most expensive 10K and 15K RPM Fibre Channel drives, with clever caching algorithmsfor quick small updates of large relational databases. However, the world is changing, and peoplenow are looking for storage designed for digital media, archives, and other Web 2.0 applications.
One problem that NEXTRA architecture addresses is RAID rebuild. In a standard RAID5 6+P+S configuration of 146GB 10K RPM drives, the loss of one disk drive module (DDM) was recovered by reconstructing the data from parity of the other drives onto the spare drive. The process took46 minutes or longer, depending on how busy the system was doing other things. During this time,if a second drive in the same rank fails, all 876GB of data are lost. Double-drive failures are rare,but unpleasant when they happen, and hopefully you have a backup on tape to recover the data from.Moving to slower, less expensive SATA drives made this situation worse. The drives have highercapacity, but run at slower speeds. When a SATA drive fails in a RAID5 array, it could take severalhours to rebuild, and that is more time exposure for a second drive failure. A rebuild for a 750GBSATA drive would take five hours or more,with 4.5 TB of data at risk during the process if a second drive failure occurs.
The Nextra architecture doesn't use traditional RAID ranks or spare DDMs. Instead, data is carved up into 1MBobjects, and each object is stored on two physically-separate drives. In the event of a DDM loss, allthe data is readable from the second copies that are spread across hundreds of drives. New copies aremade on the empty disk space of the remaining system. This process can be done for a lost 750GB drive in under20 minutes. A double-drive failure would only lose those few objects that were on both drives, so perhaps1 to 2 percent of the total data stored on that logical volume.
Losing 1 to 2 percent of data might be devastating to a large relational database, as this could impactthe entire access to the internal structure. However, this box was designed for unstructuredcontent, like medical images, music, videos, Web pages, and other discrete files. In the event of a double-drivefailure, individual files would be recovered, such as with IBM Tivoli Storage Manager backup software.
IBM will continue to offer high-speed disk arrays like the IBM System Storage DS8000 and DS4800 for OLTP applications, and offer NEXTRA for this new surge in digital content of unstructured data. Recognizing this trend, diskdrive module manufacturers will phase out 10K RPM drives, and focus on 15K RPM for OLTP, and low-speedSATA for everything else.
Update: This blog post was focused on the version of XIV box available as of January 2008 that was built by XIV prior to the IBM acquisition. IBM has since made a major revision, made available August 2008 thataddresses a variety of workloads, including database, OLTP, email, as well as digital content and unstructuredfiles. Contact your IBM or IBM Business Partner for the latest details!
Bottom line, IBM continues to celebrate the new year, while the EMC folks in Hopkington, MA will continue to nurse their hangovers. Now that's a good way to start the new year!

Yesterday, I promised I would cover other products from the Feb 12 announcement. Today I will focus on the IBM SAN768B director. Some people are confused on the differences between switchesand directors. I find there are three key differences:
- Directors are designed to be 24x7 operation, highly available with no single points of failure or repair. Generally, all components in directors are redundant and hot-swappable, including Control Processors. In switches, some components are redundant and hot-swappable, such as fans and power supplies), but not the “motherboard” or controller. Often you have to take down a switch to make firmware or major hardware changes or upgrades.
- Directors are designed to take in "blades" with different features, port counts, or protocol capabilities. You can add or remove blades while the system is up and running. Switches have a fixed number of ports. (A Small Form-factor Pluggable optical transceiver [SFP] is the component that turns electric pulses into light pulses (and visa versa). You plug the SFP into the switch, and then the fiber optic cable is plugged into the SFP).
With switches, you often start with a base number of active ports, and then can enable the rest of the ports as you need them.
- Directors have hundreds of ports. Switches tend to have 64 ports or less.
Last year, Brocade acquired McDATA. Both were OEMs for IBM, and IBM distinguished that in the naming convention. The IBM SAN***B name was used to denote products manufactured for IBM by Brocade, and a SAN***M name was used to denote products manufactured by McDATA.
At that time, Brocade and McDATA equipment did not mix very well on the same fabric, so IBM retained the naming convention so that you as a customer knew what it worked with.
Brocade now has released with new levels of both operating systems--Brocade's FOS and McDATA's EOS--and their respective fabric managers--Brocade Fabric Manager (FM) and McDATA's Enterprise Fabric Connectivity Manager (EFCM)--so that they have full interoperability.
Brocade's goal is to enhance EFCM to be a common software management platform for all of their products going forward.
IBM used the maximum port count in the name to provide some clue as to the size of the switch or director. The SAN16B-2 or the SAN32B-3 are switches that have a maximum of 16 and 32 ports. The SAN256B supports a maximumeight blades of your choosing.Two different types were supported for FC ports, a 16-port blade and a 32-port blade.If all eight were 32-port blades then the maximum was 256 ports, hence the name. But then Brocade began offering 48-port blades. Should IBM change the name? No, it decided to leave itthe SAN256B even though it can now have a maximum of 384 ports.
Not to confuse anyone, the SAN768B also has a maximum of 384 ports, in the same 14U dimensions, but with a special twist. Normally to connect two directors together you use up ports from each, in what are called "inter-switch links" (ISL).These are ports you are taking away from availability from the servers and storage controllers. The SAN768Boffers a new alternative called "inter-chassis links". Each SAN768B has two processing blades, and each has two ICL ports, so with just four two-meter (2m) cables, you get the equivalent of 128 FC 8 Gbps ISL links without using 128 individual ports on each side. That is like giving you 256 ports back for use with servers and storage!
Since IBM directors require 240 volt power, IBM TotalStorage SAN Cabinet C36 include power distribution units (PDUs). PDUs are just glorified power strips, but a new intelligent PDU (iPDU) option introduces additional intelligence to monitor energy consumption for customers looking to measure, and perhaps charge back, energy consumption to the rest of the business. You can stack two SAN768B in one cabinet, one on top of the other, and connected via ICLs, it wouldlook like one huge 768-port backbone.
As a backbone for your data center, the SAN768B is positioned for two emerging technologies:
- 8 Gbps Fibre Channel (FC)
The SAN768B is powerful enough to have 32-port blades run full speed on all ports off-blade without oversubscription. Oversubscription is an emotional topic.
Normally, blades (like switches) can handle all traffic at full speed without delays provided the in-bound and out-bound ports involved are all on the same blade. In a director, however, if you need to communicate from a port on one blade to a port on a different blade, it is possible that off-blade traffic might be constrained or delayed in its transit across the backplane.
On the SAN768B, both the 16-port and 32-port blades can run at full 8 Gbps speed, and the 48-port is exposed to oversubscription only if you have more than 32-ports running at full 8 Gbps transferring data off-blade concurrently.
The new 8 Gbps SFPs support auto-negotiation at N-1 and N-2 generation link speeds. This means that they will automatically slow down when communicating with 4Gpbs and 2 Gbps devices, but they cannot communicate with 1 Gbps devices. If you are still using 1 Gbps devices in your data center, you will need to use 4 Gbps SFPs (which also support 2 Gbps and 1 Gbps link speeds) to communicate with those older devices.
- Fibre Channel over Ethernet (FCoE)
Wikipedia has a good summary of [FCoE].
Basically, this new technology enables transport of Fibre Channel packets over 10 Gbps Ethernet links. This 10 Gbps Ethernet can also be used to carry traditional iSCSI and TCP/IP traffic. FCoE introduces new extensions to provide Fibre Channel characteristics, like being lossless, and offering consistent performance. The ANSI T11 team is driving FCoE as an open standard, and at the moment it is not fully baked. I suggest you don't buy any FCoE equipment prematurely, as pre-standard devices or host bus adapters could get you burned later when the standard is finalized.
The idea is that FCoE blades can be installed in a SAN768B along with traditional FC blades, allowing routing of traffic between traditional FC and new FCoE ports. Those who have invested in FCIP for long distance replication will be able to continue using either FC or FCoE inputs.
One of the big drivers of FCoE is IBM BladeCenter. Currently, most BladeCenter blades support both Ethernet and FC connectivity and are connected to both Ethernet and FC switches on the back of each BladeCenter chassis. With FCoE, we have the potential to run both FC and IP traffic across simpler all-Ethernet blades, connecting through all-Ethernet switches on the backs of each chassis.
For more information on the IBM SAN768B, see the [IBM Press Release]. For more detailson Brocade's strategy, here is an 8-page white paper on their[Data Center Fabric] vision.

Today, IBM announced a software/server/storage combo that out-performed both HP and Sun. Here is an excerpt from the[IBM Press Release
IBM today announced that its recently introduced E7100 Balanced Warehouse(TM), consisting of the IBM POWER6(TM) processor-based System p(TM) 570 server, the IBM System Storage(TM) DS4800 and DB2(R) Warehouse 9.5, is already lapping the field in performance. The new data warehousing solution is now ranked number one in both performance and in price/performance in the TPC-H business:
- 2 x speed-up over HP system with Oracle 10g and equal number of cores;
- 3.17 x speed up over Sun with Oracle 10g and 38 percent price advantage;
- A new world record by loading 10 terabytes (TB) data at six TB per hour (TB/hr).
"These latest benchmark results further prove IBM's strength and leadership in the business intelligence arena," said Scott Handy, vice president of marketing and strategy, IBM Power Systems. "The E7100 Balanced Warehouse is a complete data warehousing solution comprised of pre-tested, scalable and fully integrated system and storage components, designed to get customers up and running quickly to get to the real benefit of unprecedented business insight and intellect."
Those not familiar with the [IBM Balanced Warehouse], it is the productized version of DB2's ["Balanced Configuration Unit" or BCU] reference configuration. The IBM Balanced Warehouse presents a pre-tested, pre-configured solution for Business Intelligence (BI) applications. These are in the form of "building blocks" thatcan be combined to get to the size you need, with incremental growth as your business expands. Each building block expertly matches the CPU processor and RAM memory of the server, with the appropriate I/O bus, cabling, and capacity of the disk system, resulting in optimal performance.
IBM DB2 software is designed to allow you to combine multiple building blocks into a single system image. This greatly simplifies your data warehouse deployment, and can help ensure success. For example, for a 50TB deployment, you can take a base 2TB building block, add 24 more, each with 2TB of disk capacity, and have a completely balanced environment. IBM clients have built systems over 300TB in this manner with these building blocks.
The IBM Balanced Warehouse is offered in several configurations:
The [C-class models] are designed for SMB customers, employing an IBM System x server with internal or direct attached EXP3000 disk.
The [D-class models] are the next step up, offering department-level data marts and data warehouse for larger deployments, employing an IBM System x server with EXP3000 or System Storage DS3400 entry level disk.
The [E-class models] represent our top-of-the line configurations for our largest enterprise deployments. The [E6000] run Linux on an IBM System x server with System Storage DS48000 disk. The [E7000] run AIX on an IBM System p575 server with DS4800 disk. The new [E7100] mentioned above runsAIX on a POWER6-based IBM System p570 with DS4800 disk.
As I have mentioned before, in my post[Supermarketsand Specialty Shops],companies are looking for complete solutions, preferably from a single vendor like IBM, HP and Sun, rather than buying piece part components from different vendors and hoping the combined ["Frankenstein"] configuration meets business requirements.
The DS4800 is an obvious choice for this solution, providing an excellent balance of cost and performance, in a modular packaging that is ideal for the incremental growth design inherent in the IBM Balanced Warehouse philosophy. To learn more about this disk system, see the official [DS4800 website] for details, descriptions and specifications.

Well, it's Tuesday again, and that means IBM announcements!
We've got a variety of storage-related items today, so here's my quick recap:
- DS5020 and EXP520 disk systems
[IBM System Storage DS5020]
provides the functional replacement for DS4700 disk systems. These are combined controller
and 16 drives in a compact 3U package.
The EXP520 expansion drawer provides additional 16 drives per 3U drawer. A DS5020 can
support upo to six additional EXP520, for a total of 112 drives per system.
The DS5020 supports both 8 Gbps FC as well as 1GbE iSCSI.
- New Remote Support Manager (DS-RSM model RS2)
The [IBM System Storage DS-RSM Model
RS2] supports of up to 50 disk systems, any mix of DS3000, DS4000 and DS5000 series.
It includes "call home" support, which is really "email home", sending error alerts to IBM
if there are any problems. The RSM also allows IBM to dial-in to perform diagnostics before
arrival, reducing the time needed to resolve a problem. The model RS2 is a beefier model
with more processing power than the prior generation RS1.
- New Ethernet Switches
With the increased interest in iSCSI protocol, and the new upcoming Fibre Channel over
Convergence Enhanced Ethernet (FCoCEE), IBM's re-entrance into the ethernet switch market
has drawn a lot of interest.
- The [IBM Ethernet Switch r-
series] offers 4-slot, 8-slot, 16-slot, and 32-slot models. Each slot can handle either
16 10GbE ports, or 48 1GbE ports. This means up to 1,536 ports.
- The [c-series] now offers a
24-port model. This is either 24 copper and 4 fiber optic, or 24 fiber optic.
The "hybrid fiber" SFP fiber optic can handle either single or multi-mode, eliminating the
need to commit to one or the other, providing greater data center flexibility.
- The [IBM Ethernet Switch B24X]
offers 24 fiber optic (that can handle 10GbE or 1GbE) and 4 copper (10/100/1000 MbE RJ45)
- Storage Optimization and Integration Services
[IBM Storage Optimization and
Integration Services] are available. IBM service consultants use IBM's own
Storage Enterprise Resource Planner (SERP) software to evaluate your environment and provide
recommendations on how to improve your information infrastructure. This can be especially
helpful if you are looking at deploying server virtualization like VMware or Hyper-V.
As people look towards deploying a dynamic infrastructure, these new offerings can be a

Today, January 16, IBM launches its latest disk system, the DS3000 series.
There are actually three products in the DS3000 series:
The DS3200 is a 2U high, 12 drive system that attaches to servers via 3Gbps Serial Attach (SAS) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are theDS3200 specifications.
The DS3400 is a 2U high, 12 drive system that attaches to servers via 4Gbps Fibre Channel (FC) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are the DS3400 specifications.
The EXP3000 is a 2U high, 12 drive expansion drawer. It was announced back in August 2006, but is part of theoverall DS3000 series. It can be used directly with servers, but is also designed to be attached to the back of the DS3200 or DS3400 to increase capacity.Here are the EXP3000 specifications.
With this announcement, IBM provides entry-level storage at the "less-than-$5000" price point, withsupport for intermix of 10K and 15K RPM drives, and scalable up to 14.4 TB capacity.This would be ideal storage for HP, Dell, IBM System x and BladeCenter servers.

Well, it's Thursday, and today IBM is having a major launch for storage. We have lots of exciting announcements today, so here is the major highlights:
- IBM Storwize V7000 midrange disk system
Fellow blogger Rolf Potts just completed his [No Baggage Challenge], travelling around the world, twelve countries in six weeks with no luggage. I first learned of this trip from fellow published author and blogger Tim Ferriss in his post [How to Travel 12 Countries with No Baggage Whatsoever]. This trip was sponsored by a travel agency [BootsnAll.com] and travel clothing manufacturer [ScotteVest].
From New York, Rolf went to London, Paris, Madrid, Morocco, Cairo, South Africa, Bangkok Thailand, Malaysia, Singapore, New Zealand, Australia, and then back to United States. I was hoping to run into him while I was in Australia and New Zealand last month, but our schedules did not line up.
Travelingwithout baggage is more than just a convenience, it is a metaphor for the philosophy that we should keep only what we need, and leave behind what we don't. This was the approach taken by IBM in the design of the IBM Storwize V7000 midrange disk system.
The IBM Storwize V7000 disk system consists of 2U enclosures. Controller enclosures have dual-controllers and drives. Expansion enclosures have just drives. Enclosures can have either 24 smaller form factor (SFF) 2.5-inch drives, or twelve larger 3.5-inch drives. A controller enclosure can be connected up to nine expansion enclosures.
The drives are all connected via 6 Gbps SAS, and come in a variety of speeds and sizes: 300GB Solid-State Drive (SSD); 300GB/450GB/600GB high-speed 10K RPM; and 2TB low-speed 7200 RPM drives. The 12-bay enclosures can be intermixed with 24-bay enclosures on the same system, and within an enclosure different speeds and sizes can be intermixed. A half-rack system (20U) could hold as much as 480TB of raw disk capacity.
This new system, freshly designed entirely within IBM, competes directly against systems that carry a lot of baggage, including the HDS AMS, HP EVA, an EMC CLARiiON CX4 systems. Instead, we decided to keep the what we wanted from our other successful IBM products.
- Inspired by our successful XIV storage system, IBM has developed a web-based GUI that focuses on ease-of-use. This GUI uses the latest HTML5 and dojo widgets to provide an incredible user experience.
- Borrowed from our IBM DS8000 high-end disk systems, state-of-the-art device adapters provide 6 Gbps SAS connectivity with a variety of RAID levels: 0, 1, 5, 6, and 10.
- From our SAN Volume Controller, the embedded [ SVC 6.1 firmware] provides all of the features and functions normally associated with enterprise-class systems, including Easy Tier sub-LUN automated tiering between Solid-State Drives and Spinning disk, thin provisioning, external disk virtualization, point-in-time FlashCopy, disk mirroring, built-in migration capability, and long-distance synchronous and asynchronous replication.
To learn more on this, read the [announcement letter], [landing page],
[services page], as well as the blog posts from fellow master inventor and blogger Barry Whyte (IBM) at his [Storage Virtualization] blog.
- My New Book is Now Available!
Finally, the various "internal NDA" that kept me from publishing this sooner have expired, so now I have the long-awaited [Inside System Storage: Volume II], documenting IBM's transformation in its storage strategy, including behind-the-scenes commentary about IBM's acquisitions of XIV and Diligent. Available initially in paperback form. I am still working on the hard cover and eBook editions.
For those who have not yet read my first book, Inside System Storage: Volume I, it is still available from my publisher Lulu, in [hard cover], [paperback] and [eBook] editions.
- IBM System Storage DS8800
A lesson IBM learned long ago was not to make radical changes to high-end disk systems, as clients who run mission-critical applications are more concerned about reliability, availability and serviceability than they are performance or functionality. Shipping any product before it was ready meant painfully having to fix the problems in the field instead.
(EMC apparently is learning this same lesson now with their VMAX disk system. Their Engenuity code from Symmetrix DMX4 was ported over to new CLARiiON-based hardware. With several hundred boxes in the field, they have already racked up over 150 severity 1 problems, roughly half of these resulted in data loss or unavailability issues. For the sake of our mutual clients that have both IBM servers and EMC disk, I hope they get their act together soon.)
To avoid this, IBM made incremental changes to the successful design and architecture of its predecessors. The new DS8800 shares 85 percent of the stable microcode from the DS8700 system. Functions like Metro Mirror, Global Mirror, and Metro/Global Mirror, are compatible with all of the previous models of the DS8000 series, as well as previous models of the IBM Enterprise Storage Server (ESS) line.
The previous models of DS8000 series were designed to take in cold air from both front and back, and route the hot air out the top, known as chimney design. However, many companies are re-arranging their data centers into separate cold aisles and hot aisles. The new DS8800 has front-to-back cooling to help accommodate this design.
My colleague Curtis Neal would call the rest of this a "BFD" announcement, which of course stands for "Bigger, Faster and Denser". The new DS8800 scales-up to more drives than its DS8700 predecessor, and can scale-out from a single-frame 2-way system to a multi-frame 4-way system. IBM has upgraded to faster 5GHz POWER6+ processors, with dual-core 8 Gbps FC and FICON host adapters, 8 Gbps device adapters, and 6 Gbps SAS connectivity to smaller form factor (SFF) 2.5-inch SAS drives. IBM Easy Tier will provide sub-LUN automated tiering between Solid-State Drives and spinning disk. The denser packaging with SFF drives means that we can pack over 1000 drives in only three frames, compared to five frames required for the DS8700.
To learn more, read the [landing page] or the announcement letters for the machine types , , , .
- IBM System Storage SAN Volume Controller v6.1
The [IBM System Storage SAN Volume Controller] software release v6.1 brings Easy Tier sub-LUN automated tiering to the rest of the world. IBM Easy Tier moves the hottest, most active extents up to Solid-State Drives (SSD) and moves the coldest, least active down to spinning disk. This works whether the SSD is inside the SVC 2145-CF8 nodes, or in the managed disk pool.
Tired of waiting for EMC to finally deliver FAST v2 for your VMAX? It has been 18 months since they first announced that someday they would have sub-LUN automatic tiering. What is taking them so long? Why not virtualize your VMAX with SVC, and you can have it sooner!
SVC 6.1 also upgrades to a sexy new web-based GUI, which like the one for the IBM Storwize V7000, is based on the latest HTML5 and dojo widget standards. Inspired by the popular GUI from the IBM XIV Storage System, this GUI has greatly improved ease-of-use.
To learn more, read the [announcement letter] and [SVC product page].
These are just a subset of today's announcements. To see the rest, read [What's New].

Continuing this week's discussion on IBM announcements, today I'll cover our integrated systems.
The problem with spreading out these announcements across several days' worth of blog posts is that others beat you to the punch. Fellow blogger Richard Swain (IBM) has his post [Move that File], and TechTarget's Dave Raffo has an article titled [
"IBM SONAS gains policy-driven tiering, gateway to IBM XIV Storage System"].
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).
The two we introduced recently were the [IBM Information Archive] and the Scale-Out Network Attached Storage (SONAS). This week, IBM announced some enhancements as SONAS v1.1.1 release. SONAS is the productized version of IBM's Scale-Out File Services (SoFS), which I discussed in my posts [Area Rugs versus Wall-to-Wall Carpeting] and [More details about IBM's Clustered Scalable NAS].
- ILM and HSM data movement
I have covered Information Lifecycle Management several times in this post, including my posts [ILM for my iPod], [Times a Million], and [Using ILM to Save Trees], to name a few.
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.
- Asynchronous Replication
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.
- Hardware enhancements
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.

If you are ever down in Sao Paulo, Brazil, may I suggest not drinking "American amounts" of their "Brazilian Coffee". The coffee here is "robust", to say the least.
Yesterday, my blog focused on IBM iSCSI offerings that were announced in August.Also announced earlier this month, the Integrated Removable Media Manager (IRMM) on System zhas been years in the making.IRMM is a new robust systems management product for Linux® on IBM System z™ that manages open system media in heterogeneous distributed environments and virtualizes physical tape libraries. IRMM combines the capacity of multiple heterogeneous libraries into a single reservoir of tape storage that can be managed from a central point.By providing an integrated solution with the opportunity for both mainframe z/OS DFSMSrmm and distributed Tivoli® Storage Manager™ environments to be managed by IRMM, System z can now be a hub for the management of removable media.
The people who thought the "Mainframe is obsolete", and those that thought "Tape is dead", are both proven wrong again with this announcement. People are looking to deploy robust tape automation for backup and archive, and this convergence with mainframe makes perfect sense by providing business value that extends to other distributed systems.

Yesterday, I asked if you were prepared for the future? The future is now. Today, IBM announced its["New Enterprise Data Center"
] vision and strategy which spans software, hardware and services in dealing withthe latest challenges that our clients are faced with today, or will face sooner or later this century.
Here's an excerpt:
Align IT with business goals
These changes demand that IT improve cost and service delivery, manage escalating complexity, and better secure the enterprise. And aligning IT more closely with the business becomes a primary goal. The new enterprise data center is an evolutionary new model for efficient IT delivery that helps provide the freedom to drive business innovation. Through a service oriented model, IT will be able to better manage costs, improve operational performance and resiliency, and more quickly respond to business needs. This approach will deliver dynamic and seamless access to IT services and resources, improving both productivity and satisfaction.
IBM's Vision for the New Enterprise Data Center
The new enterprise data center can improve the integration of people, process, and technology in your business to help you improve efficiency and effectiveness. As you implement a new enterprise data center strategy, your infrastructure becomes open, efficient, and easy to manage. And your IT staff can move from a focus on fixing IT problems to solving business challenges. Ultimately your processes become standardized and efficient, focused on business needs rather than technology.
A lot was announced today, so I will give a quick recap now, and cover specific areas over the rest of the week.
- IBM System z10 Enteprise Class
IBM introduces its most powerful mainframe. Before you think "Wait, that's a mainframe, that doesn't apply to me"stop to consider all that IBM has done to make the mainframe an "open system" without sacrificing security oravailability:
- Open standard connectivity, including TCP/IP and now 6Gbps Infiniband and 10GbE Ethernet.
- Unix System Services. Yes, z/OS is certified to provide UNIX interfaces for today's applications.
- HFS and zFS file systems that can be mounted, shared, and used by traditional z/OS applications and JCL.
- Linux and Java. Many of today's largest websites are run on mainframes behind the scenes.
- Extreme bandwidth. The z10 EC handles up to 336 FICON channels (4Gbps) for large data processing workloads
The z10 EC is as powerful as 1,500 x86 (such as Intel or AMD) servers, but consumes 85 percent less floorspace and85 percent less energy. (They should put a "green" stripe down the front of this box just to remind everyone how energy efficient this server really is!) For more on the z10 EC, see the[Press Release].
- Enhanced IBM System Storage DS8000
With the XIV acquisition taking the role as the best place to put unstructured files for Web 2.0 applications,the IBM DS8000 can focus on its core strength, managing databases and online transactions for the mainframe.There's enough here to justify its own post, so I will cover this later.
- IT Service Management Center for z (ITSMCz)
Trust me, I don't make up these acronyms. IT Service Management are the policies and procedures for managingan IT environment, such as following the best practices documented in the IT Infrastructure Library (ITIL).In the past, IBM tools have focused on Linux, UNIX and Windows on distributed servers, but today ITSMCz bringsall of that to the mainframe! (or perhaps more correct to say "brings the mainframe to all that"!)
- IT Transformation & Optimization - Infrastructure Strategy and Planning services
I don't make up the names of our service offerings either. However, one thing is clear, it is time for peopleto re-evaluate their current data center, and come up with a new plan. The average data center is 15 years old.According to Gartner Group, more than 70 percent of the world's "Global 1000" organizations will have to make significant modifications to their data centers in the next five years. IBM can help, and is rolling outa new set of services specifically to help clients make this transition, to better align their IT to their business strategies.
- Economic Stimulus Package
IBM borrowed this idea from the U.S. government. IBM Global Financing is offering special terms and ratesfor new equipment installed by December 31 this year.

Well, it's Tuesday, and you know what that means? IBM announcements!
Today we had several for the IBM System Storage product line. Here are some of them:
- DS8000 gets thinner, leaner and faster
The 4.3 level of microcode for the IBM System Storage DS8000 series disk systems [announced enhancements] for both fixed block architecture (FBA) LUNs and count key data (CKD) volumes.
For FBA LUNs that attach to Linux, UNIX and Windows distributed systems, IBM announced DS8000 Thin Provisioning native support. Of course, many people already had this by putting IBM System Storage SAN Volume Controller (SVC) in front, but now DS8000 clients out there without SVC can also achieve benefits ofthin provisioning. This support also improves quick initialization a whopping 2.6 times faster.
For CKD volumes attached to z/OS on System z mainframes, IBM announced zHPF multitrack support for z/OS 1.9 and above. zHPF provide high performance FICON performance, and can now handle multitrack I/O transfers foreven better performance for zFS, HFS, PDSE, and extended striped data sets.
- XIV gets better connected
A lot of XIV[announced enhancements] and preview announcements centered around better connectivity. Here's a run down:
- Better host attachment connectivity by beefing up the interface modules that hold the FCP and iSCSI interface cards. XIV disk arrays have 3 to 6 of these in different configurations, and since they manage both their own disks,as well as receive host I/O requests for other disks, are basically doing double-duty.These interface modules can now be ordered as [Dual-CPU] modules.
- Better infrastructure management by connecting XIV with the industry standard SMI-S interface to IBM Tivoli Storage Productivity Center. Now, XIV can be part of the single pane of glass console that manages all of your other disk arrays, tape libraries and SAN fabrics.
- Better copy services for backups by connecting XIV with IBM Tivoli Storage Manager Advanced Copy Services. TSM for Advanced Copy Services is application aware and can coordinate XIV Snapshots similar to its current support for SVC and DS8000 FlashCopy capabilities.
- Better connectivity to security systems by supporting LDAP credentials. Before, you had individual userid and passwords for each XIV, and these were probably different than all the other userid/password combinations you have for every other box on your data center floor. IBM is working on getting all products to support theLightweight Directory Access Protocol, or [LDAP] so that we can reach the nirvana of "single sign-on",one userid/password per administrator for all IT devices in the company.
- Better support with flexible warranty periods and non-disruptive code load options.
- Better remote copy support by connecting to sites far, far away. IBM previewed that it will provideasynchronous disk mirroring from one XIV to another XIV natively. Before this, XIV's synchronous mirroring was limited to 300km distances. Many of our clients do long distance global mirroring of their XIV today behind an SVC, but again, for those out there that don't yet have an SVC, this can be a reasonable alternative.
- TS7650 ProtecTIER data deduplication appliance now offers "no dedupe" option
|In what some might consider a surprising move, IBM announced a "no dedupe" licensing option on their premiere deduplication solution, which somewhat reminds me of IBM's NOCOPY option on DS8000 FlashCopy. At first I thought "Are you kidding me?!?!" However, this new license option allows the TS7650 appliance to compete with other virtual tape libraries (VTL) that do not offer deduplication capability on an even playing field. It also allows TS7650 to be used for data that doesn'tdedupe very well, such as seismic recordings, satellite images, or what have you. There are also clients who do not yet feel comfortable to dedupe their financial records for compliance reasons.This option now allows IBM to withdraw from marketing the TS7530 non-dedupe library. Having one technology thatdoes both dedupe and no-dedupe is better than offering two separate libraries based on different technologies.|
The ProtecTIER series also announced [IP remote distance replication]. This can be used to replicate virtualtape cartridges in one ProtecTIER over to another ProtecTIER at a remote location. You can decide to replicateall or just a subset of your virtual tapes, and this feature can be used to migrate, merge or split ProtecTIERconfigurations as your needs grow. Before this support, our TS7650G clients replicated the disk repositoryusing native disk array replication technology, such as Global Mirror on the DS8000, but that meant that all data was replicated over to the secondary site. Now, with this new IP replication feature, you can be selective, and replicate only those virtual tapes that are mission critical.
The appliance now supports up to 36TB of disk capacity, and the new "IBM i" operating system on System i servers,formerly known as i5/OS.
- GPFS does Windows
IBM's General Parallel File System (GPFS) has the lion's marketshare of file systems used in the [Top 500 Supercomputers]. For a while, it was limited to just Linux and AIX operating system support, but version 3.3 [extends this to Windows 2008 on 64-bit architectures]. GPFS isthe file system used in IBM's Scale-Out File Services, the underlying technology of IBM's Cloud Computing and Storage offerings.
