The marketshare data for external disk systems has been released by IDC for 4Q09. Overall, the market dropped 0.7 percent, comparing 4Q09 versus 4Q08. While EMC was quick to remind everyone that they were able to [maintain their #1 position] in the storage subset of "external disk systems", with the same 23.7 percent marketshare they had back in 4Q08 and revenues that were essentially flat, the real story concerns the shifts in the marketplace for the other major players. IBM grew revenue 9 percent, putting it nearly 5 points of marketshare ahead of HP. HP revenues dropped 7 percent, moving it further behind. Not mentioned in the [IBM Press Release] were NetApp and Dell, neck and neck for fourth place, with NetApp gaining 16.8 percent in revenues, while Dell dropped 13.5 percent. Both NetApp and Dell now have about 8 percent marketshare each. These top five storage vendors represent nearly 70 percent of the marketshare.
Given that HP is IBM's number one competitor, not just in storage but all things IT, this was a major win. Bob Evans from InformationWeek interviews my fifth-line manager, IBM executive Rod Adkins [IBM Claims Hardware Supremacy] where he shares his views and opinions about HP, Oracle-Sun, Cisco and Dell.
I'll add my two cents on what's going on:
Shift in Servers causes Shift in Storage
Hundreds of customers are moving away from HP and Sun over to IBM servers, and with it, are chosing IBM's storage offerings as well. IBM's rock-solid strategy (which I outlined in my post [Foundations and Flavorings]) has helped explain the different products and how they are positioned. HP's use of Itanium processors, and Sun's aging SPARC line, are both reasons enough to switch to IBM's lastest POWER7 processors, running AIX, IBM i (formerly i5/OS) and Linux operating systems.
Thunder in the Clouds
Some analysts predict that by 2013, one out of five companies won't even have their own IT assets. IBM supports all flavors of private, public and hybrid cloud computing models. IBM has its own strong set of offerings, is also the number one reseller of VMware, and has cloud partnerships with both Google and Amazon. HP and Microsoft have recently formed an alliance, but they have different takes on cloud computing. HP wants to be the "infrastructure" company, but Microsoft wants to focus on its ["three screens and a public cloud"] strategy. Microsoft has decided not to make its Azure Cloud operating system available for private cloud deployments. By contrast, IBM can start you with a private cloud, then help you transition to a hybrid cloud, and finally to a public cloud.
In the latest eX5 announcement, IBM's x86-based servers can run 78 percent more virtual machines per VMware license dollar. This will give IBM an advantage as HP shifts from Itanium to an all x86-based server line.
Network Attached Storage
There seems to be a shift away from FC and iSCSI towards NAS and FCoE storage networking protocols. This bodes bad for HP's acquisition of LeftHand, and Dell's acquisition of EqualLogic. IBM's SONAS for large deployments, and N series for smaller deployments, will compete nicely against HP's StorageWorks X9000 system.
Storage on Paper no longer Eco-friendly
HP beats IBM when you include consumer products like printers, which some might consider "Storage on Paper". At IBM, we often joke that 96 percent of HP's profits come from over-priced ink cartridges. With the latest focus on the environment, people are printing less. I have been printing less myself, setting my default printer to generate a PDF file instead. There are several tools available for this, including [CutePDF] and [BullZip]. As IBM employees switch from Microsoft Office to IBM's [Lotus Symphony], it has built-in "export-to-PDF" capability as well. People are also going to their local OfficeMax or CartridgeWorld to get their cartridges refilled, rather than purchase new ones. That has to be hurting HP's bottom line.
Don't Forget About Storage Management
The leading storage management suites today are IBM's Tivoli Storage Productivity Center and EMC's Control Center. HP's Storage Essentials doesn't quite beat either of these, and management software is growing in importance to more and more customers.
This week I got a comment on my blog post [IBM Announces another SSD Disk offering!]. The exchange involved Solid State Disk storage inside the BladeCenter and System x server line. Sandeep offered his amazing performance results, but we have no way to get in contact with him. So, for those interested, I have posted on SlideShare.net a quick five-chart presentation on recent tests with various SSD offerings on the eX5 product line here:
It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
Simultaneous Background Tasks
The TSM server has many background administrative tasks:
Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.
Continuing my series of posts on the IBM Storage launch of February 9, I cover some new disk options.
IBM System Storage DCS9900
The DCS9900 uses a 4U enclosure to hold 60 (that's sixty, SIX-ZERO) drives! Normally, hot-swapable drives face the front or back surface of the rack, but these surfaces are valuable "real estate", so instead, the drives stick downward into a tray that rolls out, giving you full access to access any of the drives. The DCS9900 added support for 2TB (7200 RPM) SATA drives, and 600GB (15K RPM) SAS drives. The systems use ten-pack RAID-6 ranks, 8+2P.
(If this sounds a lot like the newly announced SONAS product, it should! The two products share "DNA", and so can be considered sister products, packing 60 drives into a 4U enclosure. By comparison, the SONAS initially only supports 1TB SATA in RAID-6 ten-packs 8+2P, and 450GB SAS in RAID-5 ten-packs 8+P+S, but now that 2TB SATA and 600GB SAS drives have been qualified for the DCS9900, we hope to qualify these for the SONAS soon as well.)
Continuing on the [IBM Storage Launch of February 9], John Sing has offered to write the following guest post about the [announcement] of IBM Scale Out Network Attached Storage [IBM SONAS]. John and I have known each other for a while, traveled the world to work with clients and speak at conferences. He is an Executive IT Consultant on the SONAS team.
Guest Post written by John Sing, IBM San Jose, California
What is IBM SONAS? It’s many things, so let’s start with this list:
It’s IBM’s delivery of a productized, pre-packaged Scale Out NAS global virtual file server, delivered in a easy-to-use appliance
IBM’s solution for large enterprise file-based storage requirements, where massive scale in capacity and extreme performance is required, especially for today’s modern analytics-based Competitive Advantage IT applications
Scales to many petabytes of usable storage and billions of files in a single global namespace
Provides integrated central management, central deployment of petabyte levels of storage
Modular commercial-off-the-shelf [COTS] building blocks. I/O, storage, network capacity scale independently of each other. Up to 30 interface nodes and 60 storage nodes, in an IBM General Parallel File System [GPFS]-based cluster. Each 10Gb CEE interface node port is capable of streaming at 900 MB/sec
Files are written in block-sized chunks, striped over as many multiple disk drives in parallel – aggregating throughput on a massive scale (both read and write), as well as providing auto-tuning, auto-balancing
Functionality delivered via one program product, IBM SONAS Software, which provides all of above functions, along with clustered CIFS, NFS v2/v3 with session auto-failover, FTP, high availability, and more
IBM SONAS makes automated tiered storage achievable and realistic at petabyte levels:
Integrated high performance parallel scan engine capable of identifying files at over 10 million files per minute per node
Integrated parallel data movement engine to physically relocate the data within tiered storage
And we’re just scratching the surface. IBM has plans to deploy additional protocols, storage hardware options, and software features.
However, the real question of interest should be, “who really needs that much storage capacity and throughput horsepower?”
The answer may surprise you. IMHO, the answer is: almost any modern enterprise that intends to stay competitive. Hmmm…… Consider this: the reason that IT exists today is no longer to simply save cost (that may have been true 10 years ago). Everyone is reducing cost… but how much competitive advantage is purchased through “let’s cut our IT budget by 10% this year”?
Notice that in today’s world, there are (many) bright people out there, changing our world every day through New Intelligence Competitive Advantage analytics-based IT applications such as real time GPS traffic data, real time energy monitoring and redirection, real time video feed with analytics, text analytics, entity analytics, real time stream computing, image recognition applications, HDTV video on demand, etc. Think of how GPS industry, cell phone / Twitter / Facebook, iPhone and iPad applications, as examples, are creating whole new industries and markets almost overnight.
Then start asking yourself, “What's behind these Competitive Advantage IT applications – as they are the ones that are driving all my storage growth? Why do they need so much storage? What do those applications mean for my storage requirements?”
To be “real-time”, long-held IT paradigms are being broken every day. Things like “data proximity”: we can no longer can extract terabytes of data from production databases and load them to a data warehouse – where’s the “real-time” in that? Instead, today’s modern analytics-based applications demand:
Multiple processes and servers (sometimes numbering in the 100s) simultaneously ….
Running against hundreds of terabytes of data of live production data, streaming in from expanding number of smarter sensors, input devices, users
Producing digital image-intensive results that must be programatically sent to an ever increasing number of mobile devices in geographically dispersed storage
Requiring parallel performance levels, that used to be the domain only of High Performance Computing (HPC)
This is a major paradigm shift in storage – and that is the solution and storage capabilities that IBM SONAS is designed to address. And of course, you should be able to save significant cost through the SONAS global virtual file server consolidation and virtualization as well.
Certainly, this topic warrants more discussion. If you found it interesting, contact me, your local IBM Business Partner or IBM Storage rep to discuss Competitive Advantage IT applications and SONAS further.
