Continuing my discussion of this week's announcements of IBM storage products, I will cover the announcements that double storage capacity per footprint.
Linear Tape Open - Generation 5
IBM announced [LTO-5 drives], the TS2250 half-height and the TS2350 full-height drives, as well as support for LTO-5 drives in its various tape libraries: TS3100, TS3200, and TS3500. The native 1.5TB capacity of the LTO-5 cartridge is nearly double the 800GB capacity of the LTO-4 predecessor. With 2:1 compression, that's 3TB of data per cartridge! Performance-wise, the data transfer rate is 140 MB/sec, about 17 percent improvement over the 120MB/sec of the LTO-4 technology. The TS2250, TS2350, TS3100 and TS3200 now all offer dual-SAS ports for higher availability.
LTO-5 carries forward many of the advancements of past generations. For example, LTO-5 continues the G-2/G-1 "backward compatibility" architecture, which means that the LTO-5 drive can read LTO-3 and LTO-4 cartridges, and can write LTO-4 cartridges. Like the LTO-3 and LTO-4, the same LTO-5 drive can read and write WORM or regular rewriteable cartridges. Like the LTO-4, the LTO-5 offers drive-level data-at-rest encryption. These use a symmetric 256-bit AES key, managed by IBM Tivoli Key Lifecycle Manager (TKLM).
One thing that is new in LTO-5 is the Long Term File System [LTFS] available on the TS2250 and TS2350, which allows you to treat the tape as a hierarchical file system, with files and folders, that you can drag and drop like any other file system.
XIV storage system
IBM [doubles the capacity of the XIV storage system] by supporting 2TB SATA drives. A full 15-module frame can hold up to 161TB of usable capacity. The smallest 6-module system with 2TB can hold up to 55TB of usable capacity. At this time, all of the drives in an XIV must be the same type, so we do not yet allow intermix of 1TB and 2TB in the same frame. The 2TB are more energy efficient, with a full 15-module frame consuming on average 6.7 kVA, compared to 7.8 kVA for the 1TB drives. The performance is roughly the same, so if, for example, your application workload got 3700 IOPS per module with 1TB drives, it will get about the same 3700 IOPS per module with 2TB drives.
The EXN1000 and EXN3000 can now double in capacity with 2TB SATA drives. These can be attached to the N3000 entry-level models, such as the N3400.
DS3000 disk system
The DS3200, DS3300 and DS3400, as well as their related expansion drawers, now supports 2TB SATA drives. This means that a single control unit with three expansion drawers can hold up to 96TB of raw capacity (48 drives).
DS8700 disk system
The DS8700 also now supports 2TB SATA drives, for a maximum raw capacity over 2PB, as well as new 600GB Fibre Channel drives. Now that IBM offers [Easy Tier] functionality, pairing Solid State Drives with slower, energy-efficient SATA disk makes a lot of financial sense.
That's a lot of announcements! As always, feel free to dig into each of the links to learn more about each product.

Well, it's Tuesday again, and that means IBM announcements! Right on the heels of our big storage launch on February 9, today IBM announced some exciting options for its modular disk systems. Let's take a look:
2TB SATA-II drives
That's right, you can now DOUBLE your capacity with 2TB SATA type-II drives on the DS3950, DS4200, DS4700, DS5020, DS5100 and DS5300 disk controllers, as well as the DS4000 EXP420, EXP520, EXP810, EXP5000 and EXP5060 expansion drawers. Here are the Announcement Letters for the [HVEC] and [AAS] ordering systems.
300GB Solid State Drives
IBM also announces 300GB solid state drives (SSD) for the DS5100 and DS5300. These are four times larger than the 73GB drives IBM offered last year, for those workloads that need high read IOPS such as Online Transaction Processing (OLTP) and Enterprise Resource Planning (ERP) applications. Here is the [Announcement Letter].
New N series model N3400
For customers that need less than the minimum 21TB that our IBM Scale-Out Network Attach Storage (SONAS) can provide, IBM offers the new N3400 unified storage disk system, with support for NFS, CIFS, iSCSI and FCP. This is a 2U high 12 drive model that can be expanded up to 136 drives, basically doubling all the stats from last year's N3300 model. Fellow blogger, Rich Swain (IBM), does a great job recapping the speeds and feeds over on his blog [News and Information about IBM N series].
It also appears that the reports and rumors of the death of the DS6800 are premature. Don't believe misleading statements from competitors, such as those found written by fellow blogger BarryB (EMC), aka "the Storage Anarchist", in his latest post [Bring Out Your Dead] showing a cute little tombstone with "Feb 2010" on the bottom. Actually, if he had bothered to read IBM's [Announcement Letter], he would have realized that IBM plans to continue to sell these until June. Of course, IBM will continue to support both new and existing DS6800 customers for many years to come.
Technically, BarryB does not make any factually incorrect statements for me to correct on his blog. The idea that a product is "dead" is, of course, just opinion, and competitors poke fun at each others' announcements every day. One could argue that the EMC V-Max was "dead" after the ITG whitepaper [Cost/Benefit Case for IBM XIV Storage System - Comparing Costs for IBM XIV and EMC V-Max Systems] demonstrated that the IBM XIV cost 63 percent less than a comparable EMC V-Max over the life of three years total cost of ownership (TCO) back in July 2009. The comparison was made with data from clients in a variety of industries including manufacturing, health care, life sciences, telecommunications, financial services, and the public sector. This could explain why so many EMC customers are buying or investigating the IBM XIV and the rest of the IBM storage portfolio.
Continuing my coverage of the Data Center Conference, held Dec 1-4 in Las Vegas, an analyst presented the challenges of managing the rapid growth in storage capacity. Administrators ability to manage storage is not keeping up with the growth. His recommendations:
Aim to just meet but not exceed service level agreements (SLAs)
Revisit past IT decisions. This includes evaluating your SAN to NAS ratio.
Embrace new technologies when they are effective, this includes cloud storage, solid state drives, and interconnect technologies like FCoCEE.
Follow vendor management best practices, update your vendor "short list".
A survey of the audience found:
20 percent have a single external storage vendor
39 percent have two external storage vendors
18 percent have three external storage vendors
23 percent have four or more external storage vendors
Throughout the industry, storage vendors are following IBM's example of using commodity hardware parts. This is because custom ASICs are expensive, and changes take a minimum of three months development time. Software-based implementations can be updated more quickly.
In terms of technologies deployed of SAN, NAS, Compliance Archive (such as the IBM Information Archive), and Virtual Tape Library (VTL) such as the IBM TS7650 ProtecTIER data deduplications solution, here was the survey of the audience:
8 percent: SAN only
14 percent: SAN and NAS
23 percent: SAN, NAS and Compliance Archive
9 percent: SAN and VTL
14 percent: SAN, NAS and VTL
32 percent: SAN, NAS, Compliance Archive and VTL
Cost reduction techniques including thin provisioning, compression, data deduplication, Quality of Service tiers, and archiving. To reduce power and cooling requirements, switch from FC to SATA disk wherever possible, and move storage out of the data center, such as on tape cartridges or cloud storage.
For emerging technologies, the following survey:
16 percent have already implemented a new emerging technology (IBM XIV, Pillar, 3PAR, etc.)
30 percent plan to do so in 12-24 months
4 percent plan to do so in 24-48 months
50 percent have no plans, and will continue to stick with traditional storage technologies
As for adopting Cloud storage, here was the survey:
14 percent already have
31 percent plan to use Cloud storage in 12-24 months
13 percent plan to use Cloud storage in 24-48 months
42 percent have no plans to adopt Cloud storage
My take-away from this is that many companies are still "exploring" into different options available to them. Fortunately, IBM offers a broad portfolio of complete end-to-end solutions to make acquiring the right mix of technologies that are optimized for your workloads possible.
Well, it's Tuesday again, and we have more IBM announcements.
XIV asynchronous mirror
For those not using XIV behind SAN Volume Controller, [XIV now offers native asynchronous mirroring] support to another XIV far, far away. Unlike other disk systems that are limited to two or three sites, an XIV can mirror to up to 15 other sites. The mirroring can be at the individual volume, or a consistency group of multiple volumes. Each mirror pair can have its own recovery point objective (RPO). For example, a consistency group of mission critical application data might be given an RPO of 30 seconds, but less important data might be given an RPO of 20 minutes. This allows the XIV to prioritize packets it sends across the network.
As with XIV synchronous mirror, this new asynchronous mirror feature can send the data over either its
Fibre Channel ports (via FCIP) or its Ethernet ports.
The IBM System Storage SAN384B and SAN768B directors now offer [two new blades!]
A 24-port FCoCEE blade where each port can handle 10Gb convergence enhanced Ethernet (CEE). CEE can be used to transmit Fibre Channel, TCP/IP, iSCSI and other Ethernet protocols. This connect directly to server's converged network adapter (CNA) cards.
A 24-port mixed blade, with 12 FC ports (1Gbps, 2Ggbs, 4Gbps, 8Gbps), 10 Ethernet ports (1GbE) and 2 Ethernet ports (10GbE). This would connect to traditional server NIC, TOE and HBA cards as well as traditional NAS, iSCSI and FC based storage devices.
IBM also announced the IBM System Storage [SAN06B-R Fibre Channel router]. This has 16 FC ports (1Gbps up to 8Gbps) and six Ethernet ports (1GbE), with support for both FC routing as well as FCIP extended distance support.
With the holiday season coming up at the end of the year, now is a great time to ask Santa for a new shiny pair of XIV systems, and some extra networking gear to connect them.
