Well, it's Tuesday, and so it is "announcement day" again! Actually, for me it is Wednesday morning herein Mumbai, India, but since I was "press embargoed" until 4pm EDT in talking about these enhancements, I had to wait until Wednesday morning here to talk about them.
World's Fastest 1TB tape drive
IBM announced its new enterprise [TS1130 tape drive]and corresponding [TS3500 tape library support]. This one has a funny back-story. Last week while we were preparing the Press Release, we debated on whether we should compare the 1TB per cartridge capacity as double that of Sun's Enterprise T10000 (500GB), or LTO-4 (800GB). The problem changed when Sun announced on Monday they too had a 1TB tape drive, so now instead ofsaying that we had the "World's First 1TB tape drive", we quickly changed this to the "World's Fastest 1TB tape drive" instead. At 160MB/sec top speed, IBM's TS1130 is 33 percent faster than Sun's latest announcement. Sun was rather vague when they will actually ship their new units, so IBM may still end up being first to deliver as well.
While EMC and other disk-only vendors have stopped claiming that "tape is dead", these recent announcements from IBM and Sun indicate that indeed tape is alive and well. IBM is able to borrow technologies from disk, such as the Giant Magneto Resistive (GMR) head over to its tape offerings, which means much of the R&D for disk applies to tape, keeping both forms ofstorage well invested. Tape continues to be the "greenest" storage option, more energy efficient than disk, optical, film, microfiche and even paper.
On the LTO front, IBM enhanced the reporting capabilities of its[TS3310] midrange tape library. This includes identifying the resource utilization of the drives, reporting on media integrity, and improved diagnostics to support library-managed encryption.
IBM System Storage DR550
As a blended disk-and-tape solution, the [IBM System Storage DR550] easily replaces the EMC Centera to meet compliance storagerequirements. IBM announced that we have greatly expanded its scalability, being able to support both 1TBdisk drives, as well as being able to attach to either IBM or Sun's 1TB tape drives.
Massive Array of Idle Disks (MAID)
IBM now offers a "Sleep Mode" in the firmware of the [IBM System Storage DCS9550], which is often called "Massive Array of Idle Disks" (MAID) or spin-down capability. This can reduce the amount of power consumed during idle times.
That's a lot of exciting stuff. I'm off to breakfast now.
Well, it's Tuesday again, and we had several announcements this month, so here is a quick recap.We had some things announce May 13, and then some more announcements today, but since I was busywith conferences, will combine them into one post for the entire month of May 2008.
This time, I thought I would go "audio" with a recording from Charlie Andrews, IBM director ofproduct marketing for IBM System Storage:
Well, its Tuesday, and that means more IBM announcements!!!
Let's do a quick recap of what was announced for storage:
We now support 1000GB SATA-II drives in the DS4000 series. This is available for the DS4200 model 7V, DS4700, DS4800 as well as the expansion drawers EXP420 and EX810. When I asked our marketing team why we weren't going to say "1TB" like everyone else, they thought 1000GB sounds bigger. I guess I should not have asked that on April Fool's day. For more details, see the IBM press releases for the [DS4200/EXP420and DS4700/DS4800/EXP810].
IBM announced new machine code Release 1.4a for the The IBM Virtualization Engine™ TS7700 virtual tape library for our System z mainframe customers.Various features come with this new level of machine code. See the IBM [Press Release] for more details.
Load balancing across the grid
Host control over the copy of logical volumes on a cluster by cluster basis
Option to gracefully remove an individual cluster from an existing grid
Initial-state reset for TS7700 database for cluster cleanup
Option to upgrade single-cache to dual-cache configuration
Also announced were updates to the 7214 model 1U2. Technically this is not in the IBM System Storage product line,but instead is designed specifically for our System p server line. This is a "media drawer" that allows you to havetape on one side, and optical on the other, in a single enclosure. IBM announced that you can now have DAT160 80GBdrives that is read-write compatible with DAT72 and DDS4 drives, and half-high LTO-4 drives that can read LTO-2 media, and is read-write compatible with LTO-3 media.Read the IBM [Press Release] for details.
Finally, if you are in the United States, Canada or the Carribean, there is a special discount promotionfor tape libraries purchased before June 20, 2008. This includes IBM TS3100, TS3200, TS3310 and TS3500 libraries.See the [Promotion Details] for eligibility.
IBM has added capability to the IBM TotalStorage Productivity Center for Replication. A quick review of the differentoptions for this component.
base Replication (uni-directional from primary to disaster site)
Two-site replication (bi-directional, including failover and failback)
Three-site replication (site awareness for all the copy sessions between all three sites in all situations)
Productivity Center for Replication supported all these levels for DS8000, DS6000 and ESS 800 disk models, butfor SVC it only supported FlashCopy and Metro Mirror for the uni-directional base. IBM announced version 3.4 today that has added support for SVC for Global Mirror (asynchronous disk mirroring) and bi-directional failover/failback. This supports lets you have "practice volumes" that allow IT managers to perform "disaster recovery exercises" without disrupting production workloads.
Also, for the DS8000, there is support for the new Space Efficient FlashCopy and DynamicVolume Expansion features. Here is the IBM
The Productivity Center for Replication server can run on either a Windows/Linux-x86 server or a z/OS mainframe server.The Productivity Center for Replication on System z offers all the same new support for SVC and DS8000, as well asincorporated Basic HyperSwap capability that I mentioned in my post last February[DS8000 Enhancements for the IBM System z10 EC].
Here are the IBM press releases for the TotalStorage Productivity Center for Replication on[Windows/Linux-x86and System z] servers.
I'm at a Business Partner conference today, discussing these announcements and other topics, so need to go back to those festivities.
Well it's Tuesday, which means its time to look at recent announcements.While I was on vacation last week, IBM made a lot of storage announcements October 23.Josh Krischer gives his summary on WikiBon [October 2007 Review].Austin Modine of the The Register went so far as to say that [IBM goes crazy with storage system updates].
IBM System Storage DS8000 series
This is "Release 3" software/microcode upgrades on our existing "Turbo" hardware.
IBM FlashCopy SE -- Here "SE" stands for Space Efficient. Rather than allocating a full 100% of the space for the FlashCopy destination, you can set aside just a fraction, and this will hold all the changed blocks, similar to whatIBM already offers on the DS4000 series.
Dynamic Volume Expansion -- In the past, if you needed more space for a LUN, you had to carve out a newer one elsewhere, and then copy the data over from the old to the new, leaving the old LUN around to be re-used or leftstranded. With this enhancement, you can just upgrade the LUN in place, making it bigger as needed, similar to whatIBM already offers on the DS4000 series and SAN Volume Controller. This applies to CKD volumes for the System zmainframe users out there as well.
Storage Pool Striping -- striping volumes across RAID ranks to eliminate or reduce hot-spots, and provide betterload balancing. Many used SAN Volume Controller in front of the DS8000 to do this, but now you can do it natively inthe DS8000 itself.
z/OS Global Mirror Multiple Reader -- for System z customers, "z/OS Global Mirror" is the new name for XRC. Thisenhancement improves the throughput of sending updates to the remote disaster recovery location.
DS Storage Manager enhancements, the element manager software has been enhanced, and is pre-installed on the new IBM System Storage Productivity Center, which I will talk about below.
Intermix of DS8000 machine types -- this is especially useful to allow new frames to have co-terminating warrantieswith the base units. In other words, as you expand your system, you can ensure that the entire chunk of iron runs outof warranty all at the same time, to simplify your decision making process to upgrade or contract for extended service.
One of the biggest complaints about IBM TotalStorage Productivity Center is that it is software that needs to beinstalled on its own server, and that this installation process can take a day or two. Why wait? Now you can havea hardware console that has the DS8000 Storage Manager software, SVC Admin Console software, and IBM TotalStorageProductivity Center "Basic Edition" pre-installed. Here are the key features.
Pre-installed and tested console
DS8000 R3 GUI integration
Cohabitation of SVC 4.2.1 GUI and CIMOM
Automated device discovery
Asset and capacity reporting, including tape library support
Our "Release 9" applies across the board, from N3000 to N5000 to N7000 series models, includingnew host bus adapters, and the new Data OnTAP 7.2.4 release level.
The Virtual File Manager (VFM) was announced as one of our latest [Storage Virtualization Solutions]. VFMprovides a global namespace that aggregates the file systems from Linux, UNIX, and Windows file servers, as well asN series storage, into a consolidated environment.
IBM's virtual tape library (VTL) for the distributed systems platform, has been enhanced to provide:
Up to 12TB of disk cache, using 750GB SATA disk.
F05 Tape Frames installed as TS7520 base units through a 32 port fibre channel switch
Support for LTO generation 4 tape drives, both as virtual tape drives and as physical tape drives within IBM automated tape libraries attached to the TS7520. This allows you to use Encryption capabilities of LTO4.
DS3000 series now supports SATA disk, and can be attached to AIX and Linux on System p servers. This appliesto the DS3200, DS3300 and DS3400 models.See the [DS3000 Announcement Letter] for more details.
Well, it is Tuesday, and that means IBM announcements. This week many of my colleagues are attending Storage Networking World [SNW] conference. Normally, the most exciting announcements are reserved for the weeks these conferences are held, but IBM apparently made an exception this week.
New Factory configurations for XIV
The first announcement is for new [factory configurations] for the IBM XIV disk system. In the past, you could only order a partial 6-module or a full 15-module rack. Today, IBM announced that there will also be 9-, 10-, 11-, 12-, 13- and 14-module configurations orderable as well.
Some FUD out in the blogosphere led some to believe that these partial configurations had to be made full 15 modules within 12 months. That is false. You can order any of these partial rack configurations and leave them as is until you need more capacity. There is no obligation to buy more capacity with these partial rack configurations.
IBM N series N6060 configurations
This second announcement indicates that the N6060 supports[672 drives]. The N6060 is the latest midrange model of IBM N series unified storage.
If you are asking "What is a 672 drive?" don't feel stupid. It actuallyrefers to the number of external drives that can be attached to the N6060. Previously, it was mis-reported that the N6060 could support as many as 840 drives, but this was not correct, and this announcement is to fixthat typo.
IBM Passport Advantage Sub-Capacity Licensing
This last announcement today relates to IBM Passport Advantage[sub-capacity licensing].Pricing products is always a challenge. You want to come up with a pricing methodology such that people who get the most use pay the most, and those who get less pay less, in a manner that everyone thinks is fair. With commodities, it is simple to price rice by the pound, or fabric by the yard, but what about IT solutions?
Some of the IBM software is based on number of processors used, so that people who have the software running on multiple machines, or machines with multiple cores, should pay more because they are getting more value. This makes sense if this software is the only thing running on that server, but today you can also have server virtualization and are running many guest operating systems, each with different applications. The solution is to use "sub-capacity" licensing. If you have a quad-core processor server, but have four guest operating systems using 25 percent of this, then each OS should only pay for one processor's worth of licensing. Since different processors have different clock speeds, IBM has standardized the calculations to a mythical "Processor Value Unit" or PVU, with a corresponding IBM License Metric Tool (ILMT).
Initially, this will cover specific versions of Citrix Xen Server, Microsoft Hyper-V and VMware, but IBM has made as a "statement of direction" that it will extend this sub-capacity licensing and ILMT support to IBM PowerVM capability for its POWER systems.
I have often heard clients complain that their third party software vendor does not support these hypervisors. Sometimes, this means the third party vendor will not fix or provide assistance if the problem occurs in this environment, and other times, it is that the pricing does not favor this environment, you get charged for all the processors, even if your slice of the processor is much smaller.
If you are at SNW this week, stop by and say "Hi" to my fellow IBM collegues for me.
The proof-of-concept that IBM Haifa research center developed back in 1998 became what we now call the iSCSI protocol.The book iSCSI: The Universal Storage Connection introduces the history as follows:
In the fall of 1999 IBM and Cisco met to discuss the possibility of combining their SCSI-over-TCP/IP efforts. After Cisco saw IBM's demonstration of SCSI over TCP/IP, the two companies agreed to develop a proposal that would be taken to the IETF for standardization.
There are three ways to introduce iSCSI into your data center:
Through a gateway, like the IBM System Storage N series gateway, that allows iSCSI-based servers connect to FC-based storage devices
Through a SAN switch or director, a FC-based server can access iSCSI-based storage, an iSCSI-based server accessing FC-based storage, or even iSCSI-based servers attaching to iSCSI-based storage.
Directly through the storage controller.
IBM has been delivering the first method with its successful IBM System Storage N series gateway products, buttoday we have announced additional support for the second and third methods.Here's a quick recap.
New SAN director blades
Supporting the second method, IBM TotalStorage SAN256B Director is enhanced to deliver iSCSI functionality with a new M48 iSCSI Blade, which includes 16 ports (8 Fibre Channel ports; and 8 Ethernet ports for iSCSI connectivity). We also announced a new Fibre Channel M48 Blade which provides 10 Gbps Fibre Channel Inter Switch Link (ISL) connectivity between SAN256B Directors.
With support for Boot-over-iSCSI, diskless rack-optimized and blade servers can boot Windows or Linux over Ethernet,eliminating the management hassles with internal disk.
All of this is part of IBM's overall push into the Small and Medium size Business marketplace, making it easier to shop for and buy from IBM and its many IBM Business Partners, easier to deploy and install storage, and easier tomanage the storage once you have it.
It's Tuesday, which means IBM makes its announcements. We had several for the IBM System Storage product line. Here's a quick recap.
The IBM System Storage DS3000 now offers DC power models.New DC powered models of the DS3200, DS3400, and EXP3000 are well suited for Telco industry environments, as theseare NEBS and ETSI compliant and are powered by an industry standard 48 volt DC power source.
Also, the IBM System Storage N series now supports750GB SATA drives available for the EXN1000 drawer.
IBM Virtualization Engine TS7740now supports 3-cluster grids. Unlike 3-way replication on disk mirroring, such as IBM Metro/Global Mirror for the DS8000 that enforces a primary, secondary and tertiary copy, the grid implementation of TS7740 tape virtualization allows for any-to-any mirroring. Existing standalone TS7740 clusters can be converted to grid-enabled. A "Copy Export" feature allows virtual tapes to be exported onto physical tape. And in keeping with our theme of "enabling business flexibility", performance throughput can now be purchased in 100 MB/sec increments, up to 600 MB/sec, to match your workload bandwidth requirements.
The IBM System Storage TS1120drives installed in the IBM System Storage™ TS3400 Tape Library can now be attached to System z platforms using the IBM System Storage™ TS1120 Tape Controller. Before this, the TS3400 could only be attached to UNIX, Windows and Linux systems.
The IBM System StorageTS2230 Express is offered as an external stand-alone or rack-mountable unit. This model incorporates the new LTO IBM Ultrium 3 Serial Attached SCSI (SAS) Half-High Tape Drive, and a 3 Gbps single port SAS interface for a connection to a wide spectrum of distributed system servers that support Microsoft Windows and Linux systems.
IBM has added theCisco MDS 9124 for IBM System Storageentry-level fabric switch as an Express offering and part of the IBM Express Advantage Program. Express offerings are specifically created for mid-market companies and are well suited for workgroup storage applications like e-mail serving, collaborative databases and web serving. They bring enterprise-class performance, scalability and features to small and medium-sized companies and are easy to use, highly scalable, and cost-effective.This will make it easier for IBM Business Partners to provide fabric switch connectivity for:
Storage consolidation solutions with IBM System Storage™ DS4000 Express disk arrays, especially the DS4700 Express.
Backup / restore solutions with IBM System Storage™ TS3000 Tape Libraries, such as the TS3200.
Archive and Retention
Ordering large configurations of the IBM System Storage Grid Access Manager just got a lot easier.New features enable configurations greater than 500 TB to be submitted as a single order. No change in the actualproduct, just an improvement in the ordering process.
For System p and System i servers, the IBM 3996 Optical library now supports Gen 2 60GB optical cartridges. These can be read/write or WORM cartridges.
I'm off to Denver, Colorado this week. I hope it is cooler there than it is down here in Tucson, Arizona.
Yesterday (September 7, 2006) the Eclipse Foundation announced that it has approved the creation of the Aperi Storage Management Framework Project.
There's been a lot of confusion out there about Aperi, so I thought I would post some facts and opinions about this exciting new project. A few years ago, I was thelead architect for IBM TotalStorage Productivity Center, IBM's infrastructure management product that helped launch the creation of Aperi.
From the latin word for "open", Aperi is an open source project that aims to simplify the management of storage environments, using the Storage Management Initiative - Specification (SMI-S) open standardto promote interoperability and eliminate complexity in today’s storage environments.
Aperi should provide immediate value upon install with basic storage management capabilities, rather than just simply a collection of components that require costly integration. We've discussed requirements for functions such as:
Resource discovery, monitoring, and reporting
Fabric Topology mapping
Disk / Tape management
Device configuration & LUN assignment
SAN fabric management
Basic asset management
The big confusion most people have is Aperi's relation to SMI-S and the Storage Networking Industry Association (SNIA)open standards group. The best way to explain this is to go backto your High School SAT college-entrance exams. Remember questions like this?
(The answer: a crumb is to bread like a splinter is to wood.)
Aperi is an implementation of SMI-S standard, similar to MySQL or PostgreSQL areopen standard relational database implementations of Structured Query Language (SQL).These compete with proprietary database implementations such as IBM DB2 Universal Database,Oracle Database, Microsoft SQL Server, or Sybase.
Aperi: SMI-S :: PostgreSQL : Structured Query Language (SQL)
It is often the case that the folks writing the code are different than the folks defining the standards. This is the case between the members of Aperi writing code, and the members of the SNIA writing standards. IBM happens tohave employees writing Aperi code, and other employees helping define SMI-S standards.What can I say, IBM is a big company and a leader in many areas.
A good analogyis how the Apache community has developed an awesome web server, and the Firefox Mozillacommunity have developed an awesome web browser, both of which are implementations of the HTTP/HTML standards adopted by the World Wide Web Consortium. Apache and Firefoxcompete with proprietary implementations, such as Microsoft Internet Information Services(IIS) web server and Internet Explorer web browser.
Aperi: SNIA :: Apache : World Wide Web (WWW) Consortium
With this arrangement, Aperi and the SNIA will have very complementary roles in defining and driving standards across the entire storage market. To that end, Aperi will make extensive use of the SNIA’s Technology Center and SNIA’s “plugfests” to test the interoperability of the Aperi framework with the variety of 3rd-party storage offerings available. By providing a tested implementation of SMI-S, Aperi will drive broader industry availability of SMI-S, as well as offer the many benefits of an industry-backed open source community.
Check out this vote of confidence:
"Eclipse's Aperi Project will further advance the adoption of SNIA's SMI-S, benefiting the entire storage industry and IT community. Furthermore, the SNIA and Aperi will define plans to collaborate on new storage standards, standards testing programs, and storage interoperability programs." --- Wayne M. Adams, chair, SNIA Board of directors
So, both proprietary and open source implementations have their place in the world.Proprietary products are needed for advanced, unique value-add, and opensource projects are for basic support focused on interoperability and flexibility.These can be combined, for example, proprietary "plug-ins" built on an open source base. The more choices the client has, the better.
Storage vendors benefit too. Vendors are tired of being in the "Y.A.C." business, building "Yet Another Configurator" for each new device developed, with basic functionsto carve LUNs, read performance stats, and so on. By shipping Aperi instead, storagevendors like IBM can invest their development dollars in real innovations, things thatmatter for the customer.
It's Tuesday, which means IBM announcements, and today IBM made some major announcementsthat support a [Dynamic Infrastructure]! I hinted at this yesterday, choosing the week's theme to be all about Cloud Computing and Alternative Sourcing. I will briefly highlight today's announcements related to storage here, and try to go into more detail over the next few weeks.
Ethernet switches and routers
In support of Cloud Computing and Cloud Storage, IBM is now back in theEthernet networking business. This is part of storage as protocols likeiSCSI, CIFS and NFS are gaining prominence. Extending IBM's existing OEMrelationship with Brocade, there are four series:
[c-series] - "c" for Compact, these are 1U high fixed port switches
[g-series] - "g" for Pay-as-you-Grow using IronStack stacking technology to allow up to 8 switches to be glommed, glued, er.. "gathered" together as a single virtual chassis.
[m-series] - "m" for Multiprotocol Label Switching [MPLS] which supports routing between LAN and WAN networks over OC12 and OC48 lines.
[s-series] - "s" for slots, the B08S has eight slots, and the B16S has sixteen slots, supporting up to 384 ports. These models support Power-over-Ethernet [PoE] that simplifies attaching Voice-over-IP (VoIP) telephones and IP-based surveillance cameras.
IBM announced it will strengthen its partnership with Juniper Networks, and continues to consider Cisco a strategic partner as well. To help customer position themselves for Cloud Computing and Cloud Storage,IBM also launches some new services:
The IBM [DS5000] now supports self-encrypting disk drives, known also as "full-disk encryption" or FDE, for added security, and 8Gbps Fibre Channel (FC) ports for added performance. The DS5300 model in particular now supports up to 448 disk drives for added scalability.
Comprehensive Data Protection Solution
IBM's [Data Protection Solution] shows off IBM's awesome synergy between servers, storage and software. Combining System x servers, Tivoli Storage Manager FastBack software, and DS5000, DS4000 or DS3000 series disk systems. The solution is designed to both Windows-based servers and their applications, offering bare metal restores, and application–level protection for Oracle, SQL, Exchange and SAP.
Tivoli Storage Productivity Center
Last February, IBM previewed the renaming of TotalStorage Productivity Center to its new name,Tivoli Storage Productivity Center. Today, IBM announces [Tivoli Storage Productivity Center v4.1]. Some key changes include:
Productivity Center for Fabric has been merged into Productivity Center for Disk
Productivity Center for Replication is now integrated, but remains separately licensed
Productivity Center can now feed input to IBM's Novus Storage Enterprise Resource Planner [SERP]
TS7650 ProtecTIER Data Deduplication IP-based replication
IBM previews IP-based replication which allows the TS7650 appliance or TS7650G gateway to sendvirtual tape data over to a remote location. This is instead of having the underlying disk systemsperform the replication on its behalf. Having the TS7650 do the replication is preferred, as itcan maintain virtual cartridge integrity, when a virtual tape is unmounted the replication can beginat that point.
For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
