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.
Well, it's Tuesday again, and that means IBM announcements! Today we had a major launch, with so many products, services and offerings
that I can't fit them all into a single post, so I will split them up into several posts to give the attention they deserve. So, in this
post, I will focus on just the networking gear.
IBM Converged Switch B32
The "Converged" part of this switch refers to Converged Enhanced Ethernet (CEE), which is just a lossless Ethernet that meets certain standards to allow Fibre Channel over Ethernet (FCoE) that are still being discussed between Brocade and Cisco. Thankfully, IBM demanded both Brocade and Cisco stick to open agreed-upon standards, and the rest of the world gets to benefit from IBM's leadership in keeping everything as open and non-proprietary as possible.
The B32 ("B" because it was made by Brocade) starts with 24 10Gb Converged Enhanced Ethernet (CEE) ports, and then you can add eight Fibre Channel ports, for a total of 32 ports, hence the name B32. These are designed to be Top-of-Rack (TOR) switches. Basically, instead of having expensive optical cables for Ethernet and/or Fibre Channel out of each server, you have cheap twinax copper cables connecting the server's Converged Network Adapters (CNA) to this TOR switch, and then you can have the 10Gb Ethernet go to your regular Ethernet LAN, and your 8Gbps FC traffic go to your regular FC SAN. In other words, the CNA serves both the role of an Ethernet Network Interface Card (NIC) as well as a Fibre Channel Host Bus Adapter (HBA) card.
(You might see 8Gbps Fibre Channel represented as 8/4/2 or 2/4/8, this is just to remind you that these 8Gb FC ports can auto-negotiate down to 2Gbps and 4Gbps legacy hardware, but not 1Gbps. If you are still using 1Gbps FC, you need 4Gpbs SFP transceivers instead, shown often as 1/2/4 or 4/2/1.)
New SSN-16 module for Cisco directors and switches
When I present SAN gear to sales reps, I often get the question, "What is the difference between a switch and a director?" My quick and simple answer is that switches have fixed ports, but directors have slots that you can slide in different blades or expansion modules. The Cisco MDS9500 series are directors with slots, the three models provide a hint to their capacity. The last two digits represent the number of total slots, but the first two slots are already taken. In other words, model 9513 has 11 slots, model 9509 has seven slots, and model 9506 has four slots. You can have a 48-port blade in a slot, so in theory, you can have a maximum of 528 ports on the biggest model 9513.
However, if you want FCIP for disaster recovery, or I/O Acceleration (IOA) for remote e-vaulting tape libraries, you need a special 18/4 blade. This has 18 FC ports, four 1GbE ports and a special service processor that speaks FCIP or IOA. If you wanted two service processors for FCIP and two for IOA, you would need four of these blades, and that takes up slots that could have been used for 48-port blades instead. The solution? The new SSN-16 has sixteen 1GbE ports and four service processors, so with one slot, you can handle the FCIP and IOA processing that you previously used four cards, giving you three slots back to use with higher port-density cards.
Even better, you can put this new SSN-16 in the Cisco 9222i. The model 9222i is a "hybrid" switch with 22 fixed ports (18 FC ports, four fixed 1GbE ports, and a service processor, so basically the fixed port version of the 18/4 blade above), but it also has one slot! That one slot can be used for the SSN-16 to give you added FCIP or IOA capability.
For our mainframe clients, the FICON package includes four 24-port FICON blades and 96 SFP 4Gbps transceivers to fully populate them. Here is the IBM [Press Release].
Cisco Nexus 5000 series for IBM System Storage
The Cisco Nexus 5000 series is Cisco's entry into the Converged Enhanced Ethernet world, although Cisco sometimes refers to this as Data Center Ethernet (DCE), IBM will continue to use CEE when referring to either Brocade and Cisco gear. These are also Top-of-Rack aggregators that support CNA connections over cheaper twinax copper wires. Model 5010 has 10 ports that can be configured for either 1GbE or 10Gb CEE, 10 ports that are 10Gb CEE, and a slot for an expansion module. The Model 5020 has basically twice as much of everything, including two slots instead of one. Since 10Gb Ethernet does not auto-negotiate down to 1GbE, half the ports can be configured to run 1GbE instead. Frankly, that can be seen as wasting your precious Nexus ports with 1GbE connections, so you might find a 1GbE-to-10GbE aggregator that combines a dozen or more 1GbE to a few 10GbE links instead.
Today's announcement is that in addition to 10GbE and 4Gbps FC expansion modules, there is now an expansion module that supports 8Gbps Fibre Channel. Here is the IBM [Press Release].
Whether you choose Brocade or Cisco, nearly all of IBM System Storage disk and tape products can work today with Converged Enhanced Ethernet environments, either directly using iSCSI, NFS or CIFS, or using the FCoE methodology.
As you can see, it took me a whole post just to cover just our networking gear announcements, and I haven't even covered our disk, tape and cloud storage offerings. I'll get to these in later posts.
In addition to dominating the gaming world, producing chips for the Nintendo Wii, Sony PlayStation, and Microsoft Xbox 360, IBM also dominates the world of Linux and UNIX servers. Today, IBM announced its new POWER7 processor, and a line of servers that use this technology. Here is a quick [3-minute video] about the POWER7.
While others might be [Dancing on Sun's grave], IBM instead is focused on providing value to the marketplace. Here is another quick [2-minute video] about why thousands of companies have switched from Sun, HP and Dell over to IBM.
