This week several IBM executives will present at the 28th Annual Data Center Conference here in Las Vegas. Here is a quick recap:
Steve Sams: Data Center Cost Saving Actions Your CFO Will Love
A startling 78 percent of today's data centers were built in the last century, before the "dot com" era and the adoption of high-density blade servers. IBM Vice President of Global Site and Facility Services, Steve Sams, presented actions that can help extend the life of existing data centers, help rationalize the infrastructure across the company, and design a new data center that is flexible and responsive to changing needs.
In one example, an 85,000 square foot datacenter in Lexington had reached 98 percent capacity based on power/cooling requirements. They estimated it would take $53 million US dollars to either upgrade the facility or build a new facility to meet projected growth. Instead, IBM was able to consolidate servers six-to-one, an 85 percent reduction. IBM also was able to make changes to the cooling equipment, redirect airflow and changed out the tiles, re-oriented the servers for more optimal placement, and implement measurement and management tools. The end result? The facility now has eight times the compute capability and enjoys 15 percent headroom for additonal growth. All this for only 1.5 million US dollar investment, instead of 53 million.
IBM builds hundreds of data centers for clients large and small. In addition to the "Portable Modular Data Center"(PMDC) shipping container on display at the Solution Showcase, IBM offers the "Scalable Modular Data Center", a turn-key system with a small 500 to 2500 square foot size for small customers. For larger deployments, the "Enterprise Modular Data Center" offers standardized deployments in 5000 square foot increments. IBM also offers "High Density Zones" which can be perfect way to avoid a full site retrofit.
Helene Armitage: IT-wide Virtualization
Helene is IBM General Manager of the newly formed IBM System Software division. A smarter planet will require more dynamic infrastructures, which is IBM's approach to helping clients through the virtualization journey. The virtualization of resources, workloads and business processes will require end-to-end management. To help, IBM offers IBM Systems Director.
Helene indicated that there are four stages of adoption:
Physical consolidation - VMware and Hyper-V are the latest examples of running many applications on fewer physical servers. Of course, IBM has been doing this for decades with mainframes, and has had virtualization on System i and System p POWER systems as well. A quick survey of the audience found that about 20 percent were doing server virtualization on non-x86 platforms (for example, PowerVM or System z mainframe z/VM)
Pools of resources - SAN Volume Controller is an example solution to manage storage as a pool of disparate storage resources. Supercomputers manage pools of servers.
Integrated Service Management - in the past, resources were managed by domain, resulting in islands of management. Now, with IBM Systems Director, you can manage AIX, IBM i, Linux and Windows servers, including non-IBM servers running Linux and Windows.
Service management can provide monitoring, provisioning, service catalog, self-service, and business-aligned processes.
Cloud computing - Helene agreed that not everyone will get to this stage. Some will adopt cloud computing, whether public, private or some kind of hybrid, and others may be fine at stage 3.
For those clients that want assistance, IBM offers three levels of help:
Help me decide what is best for me
Help me implement what I have decided to do
Help me manage and run my operations
With IBM's compelling vision for the future, best of breed solutions, leadership in management software, extensive experience in services, and solid business industry knowledge, it makes sense to tap IBM to help with your next IT transformation.
Continuing my coverage of the Data Center Conference 2009, held Dec 1-4 in Las Vegas, the title of this session refers to the mess of "management standards" for Cloud Computing.
The analyst quickly reviewed the concepts of IaaS (Amazon EC2, for example), PaaS (Microsoft Azure, for example), and SaaS (IBM LotusLive, for example). The problem is that each provider has developed their own set of APIs.
(One exception was [Eucalyptus], which adopts the Amazon EC2, S3 and EBS style of interfaces. Eucalyptus is an open-source infrastrcture that stands for "Elastic Utility Computing Architecture Linking Your Programs To Useful Systems". You can build your own private cloud using the new Cloud APIs included Ubuntu Linux 9.10 Karmic Koala termed Ubuntu Enterprise Cloud (UEC). See these instructions in InformationWeek article [Roll Your Own Ubuntu Private Cloud].)
The analyst went into specific Virtual Infrastructure (VI) and public cloud providers.
Private Clouds can be managed by VMware tools. For remote management of public IaaS clouds, there is [vCloud Express], and for SaaS, a new service called [VMware Go].
Citrix is the Open Service Champion. For private clouds based on Xen Server, they have launched the [Xen Cloud Project] to help manage. For public clouds, they have [Citrix Cloud Center, C3], including an Amazon-based "Citrix C3 Labs" for developing and testing applications. For SaaS, they have [GoToMyPC and [GoToAssist].
Amazon offers a set of Cloud computing capabilities called Amazon Web Services [AWS]. For virtual private clouds, use the AWS Management Console. For IaaS (Amazon EC2), use [CloudWatch] which includes Elastic Load Balancing.
If you prefer a common management system independent of cloud provider, or perhaps across multiple cloud providers, you may want to consider one of the "Big 4" instead. These are the top four system management software vendors: IBM, HP, BMC Software, and Computer Associates (CA).
A survey of the audience found the number one challenge was "integration". How to integrate new cloud services into an existing traditional data center. Who will give you confidence to deliver not tools for remote management of external cloud services? Survey shows:
28 percent: VI Providers (VMware, Citrix, Microsoft)
19 percent: Big 4 System Management software vendors (IBM, HP, BMC, CA)
13 percent: Public cloud providers (Amazon, Google)
40 percent: Other/Don't Know
For internal private on-promise Clouds, the results were different:
40 percent: VI Providers (VMware, Citrix, Microsoft)
21 percent: Big 4 System Management software vendors (IBM, HP, BMC, CA)
13 percent: Emerging players (Eucalyptus)
26 percent: Other/Don't Know
Some final thoughts offered by the analyst. First, nearly a third of all IT vendors disappear after two years, and the cloud will probably have similar, if not worse, track record. Traditional server, storage and network administrators should not consider Cloud technologies as a death knell for in-house on-premises IT. Companies should probably explore a mix of private and public cloud options.
Continuing my coverage of last week's Data Center Conference 2009, held Dec 1-4 in Las Vegas, I attended an interesting session related to the battles between Linux, UNIX, Windows and other operating systems. Of course, it is no longer between general purpose operating systems, there are also thin appliances and "Meta OS" such as cloud or Real Time Infrastructure (RTI).
One big development is "context awareness". For the most part, Operating Systems assume they are one-to-one with the hardware they are running on, and Hypervisors like PowerVM, VMware, Xen and Hyper-V have worked by giving OS guests the appearance that this is the case. However, there is growing technology for OS guests to be "aware" they are running as guests, and to be aware of other guests running on the same Hypervisor.
The analyst divided up Operating Systems into three categories:
Operating systems that are typically used to support other OS by offering Web support or other infrastructure. Linux on POWER was an example given.
DBMS/Industry Vertical Applications
Operating systems that are strong for Data Base Management Systems (DBMS) and vertical industry applications. z/OS, AIX, HP-UX, HP NonStop, HP OpenVMS were given as examples.
General Purpose for a variety of applications
Operating systems that can run a range of applications, from Web/Infrastructure, DBMS/Vertical Apps, to others. Windows, Linux x86 and Solaris were offered as examples.
The analyst indicated that what really drove the acceptance or decline of Operating Systems were the applications available. When Software Development firms must choose which OS to support, they typically have to evaluate the different categories of marketplace acceptance:
For developing new applications: Windows-x86 and Linux-x86 are must-haves now
Declining but still valid are UNIX-RISC and UNIX-Itanium platforms
Viable niche are Non-x86 Windows (such as Windows-Itanium) and non-x86 Linux (Linux on POWER, Linux on System z)
Entrenched Legacy including z/OS and IBM i (formerly known as i5/OS or OS/400)
For the UNIX world, there is a three-legged stool. If any leg breaks, the entire system falls apart.
The CPU architecture: Itanium, SPARC and POWER based chipsets
Operating System: AIX, HP-UX and Solaris
Software stacks: SAP, Oracle, etc.
Of these, the analyst consider IBM POWER running AIX to be the safest investment. For those who prefer HP Integrity, consider waiting until "Tukwilla" codename project which will introduce new Itanium chipset in 2Q2010. For Sun SPARC, the European Union (EU) delay could impact user confidence in this platform. The future of SPARC remains now in the hands of Fujitsu and Oracle.
What platform will the audience invest in most over the next 5 years?
45 percent Windows
14 percent UNIX
37 percent Linux
4 percent z/OS
A survey of the audience about current comfort level of Solaris:
10 percent: still consider Solaris to be Strategic for their data center operations and will continue to use it
25 percent: will continue to use Solaris, but in more of a tactical way on a case-by-case basis
30 percent: have already begun migrating away
35 percent: Do not run Solaris
The analyst mentioned Microsoft's upcoming Windows Server 2008 R2, which will run only on 64-bit hardware but support both 32-bit and 64-bit applications. It will provide scalability up to 256 processor cores. Microsoft wants Windows to get into the High Performance Computing (HPC) marketplace, but this is currently dominated by Linux and AIX. The analyst's advice to Microsoft: System Center should manage both Windows and Linux.
Has Linux lost its popularity? The analyst indicated that companies are still running mission critical applications on non-Linux platforms, primarily z/OS, Solaris and Windows. What does help Linux are old UNIX Legacy applications, the existence of OpenSolaris x86, Oracle's Enterprise Linux, VMware and Hyper-V support for Linux, Linux on System z mainframe, and other legacy operating systems that are growing obsolete. One issue cited with Linux is scalability. Performance on systems with more than 32 processor cores is unpredictable. More mature operating systems like z/OS and AIX have stronger support for high-core environments.
A survey of the audience of which Linux or UNIX OS were most strategic to their operations resulted in the following weighted scores:
140 points: Red Hat Linux
71 points: AIX
80 points: Solaris
40 points: HP-UX
41 points: Novell SUSE Linux
19 points: Oracle Enterprise Linux
29 points: Other
The analyst wrapped up with an incredibly useful chart that summarizes the key reasons companies migrate from one OS platform to another:
Reduce Costs, Adopt HPC
DBMS, Complex projects
Availability of Admin Skills
Performance, Mission Critical Applications
Availability of Apps, leave incumbent UNIX server vendor
Consolidation, Reduce Costs
Certainly, all three types of operating system have a place, but there are definite trends and shifts in this marketspace.
Continuing my coverage of last week's Data Center Conference 2009, I attended another "User Experience" that was very well received. This time, it was Henry Sienkiewicz of the Department Information Systems Agency (DISA) presenting a real-world example of the business model behind a private cloud implementation. DISA is the US government agency that develops and runs software for the Army, Navy and Air Force.
Being part of the military presents its own unique set of challenges:
Acquisition of hardware to develop and test software is difficult
Budgets fluctuate so an elastic pay-for-use was desirable
End user access had to be secure and meet government regulations
It had to meet the technical aspects of scalable, elastic, dynamic, multi-tenant using shared resources
Using Cloud Computing simplifies provisioning, encourages the use of standards, and provides self-service. DISA has several solutions.
Rapid Access Computing Environment (RACE)
RACE is an internal private cloud with 24-hour provisioning for development and test requests, and 72 hour provisioning for production requests. The amount used is billed on a month-to-month basis, and offers a self-service portal so that developers and administrators can just pick and choose what they need. The result is a hosted server, similar to what you get from 1and1.com or GoDaddy.
Global Content Delivery Service (GCDS)
This provides long-term storage of data. An internal version of "Cloud Storage" for archive and fixed content.
This provides a place to maintain source code, basically their internal version of "SourceForge" used by Open Source projects.
In their traditional approach, a software project would take six months to procure the hardware, another 6-12 months code and test, and then another 6 months in certification, for a total of 18-24 months. With the new Cloud Computing approach that DISA adopted, procurement was down to 24-72 hours with RACE, code test took only 2-6 months with Forge.Mil, and certification could be done in days on RACE, resulting in a new total of only 3-6 months. Some challenges they found:
Service Level management and continuing the use of ITIL best practices
Balancing Military-level Security with Self-service Usability
Internal Funding and Chargeback, they had even adopted a way for developers to pay with their credit card
Cultural inertia, developers don't like to change or do things in a different way
Some lessons learned from this two-year experience:
It's a journey. Most of the user experiences for cloud adoption took two or more years to complete
Infrastructure Fundamentals continue to matter
Know your "marketplace", in this case, software development for military applications
Engage in your end-users early. In this case, Henry had wished he had involved input from software developers that would be using RACE, GCDS and Forge.MIL earlier in the process.
Return on Value analysis, this is different than Return on Investment, as many of the benefits of cloud like higher morale are intangible at first
Avoid fixed costs in negotiations with vendors. For example, he cited they use a lot of IBM because of IBM's pay-for-use billing model. They pay for MIPS used on IBM mainframes, and their IBM Tivoli software pricing is usage-based.
IBM makes another breakthrough today with an announcement about tape data density. Unlike hard disk drive technologies that are hitting physical limits, IBM is proving that tape technology still has plenty of life in its future.
When I first started working for IBM in Tucson, back in 1986, a 3420 tape reel held only 180MB of data, and a 3480 tape cartridge improved this to 200MB of data. Today's enterprise tapes, like 3592 cartridges for the TS1130 drives, or LTO4 cartridges for the IBM TS1040 drives, are half-inch wide, half-mile long, and can store 1 TB or more of data per cartridge, depending on how well the data can compress. To increase cartridge capacity, designers can make changes in three dimensions:
Wider tape: The film industry tried this, going from 35mm to 70mm film, only to find that most cinemas did not want to upgrade their equipment. Keeping the media dimensions to half inch wide allows much of the engineering hardware to continue unchanged.
Longer tape: The problem with longer tape is that either the reel inside gets fatter, or you need to develop flatter media to fit within the existing cartridge dimensions. Wider reels means a bigger tape cartridge external dimensions, forcing changes to shelving units, cartridge trays, and carrying units. The media just can't get any flatter without risking getting more brittle.
Denser bit recording: once a convenient width and length were established, improving bit density turned out to be the best way to increase cartridge capacity.
Working with FujiFilm Corporation of Japan, my colleagues at IBM Research facility in Zurich were able to demonstrate an incredible 29.5 Gigabits per square inch, nearly 40 times more dense than today's commercial tape technology. In the near future, we will be able to hold a 35TB tape cartridge in our hand. There was actually a lot to make this happen, improved giant magentoresistive read/write heads, better servo patterns to stay on track, thinner tracks less than a micron thick, and better signal-to-noise processing to accomplish this. To learn more, you can read the [Press Release] or watch this quick [4-minute YouTube video].
To avoid overwhelming people with too many features and functions, IBM decided to keep things simple for the first release. Let's take a look:
The base frame (2231-IA3) supports a single collection, from as small as 3.6 TB to as large as 72 TB of usable capacity. You can attach one expansion frame (2231-IS3) that holds two additional collections, 63 TB usable capacity for each collection. Disk capacity is increased in eight-drive (half-drawer) increments of 3.6 TB usable capacity each. A full configured IA system (304 drives, 1 TB raw capacity per drive) provides 198 TB usable capacity.
Of course, that is just the disk side of the solution. Like its predecessor, the IBM System Storage DR550, the IA v1.1 can also attach to external tape storage to store and protect petabytes (PB) of archive data. Hundreds of different IBM and non-IBM tape drives and libraries are supported, so that this can be easily incorporated into existing tape environments.
Each collection can be configured to one of three protection levels: basic, intermediate, and maximum.
Basic protection provides RAID protection of data using standard NFS group/user controls for access to read and write data. This can be useful for databases that need full read/write access. Users can assign expiration dates, but in Basic mode they can delete the data before the expiration date is reached.
Intermediate adds Non-Erasable Non-Rewriteable (NENR) protection against user actions to delete or modify protected data. However, similar to IBM N series "Enterprise SnapLock", intermediate mode allows authorized storage admins to clean up the mess, increase or reduce retention periods, and delete data if it is inadvertently protected. I often refer to this as "training wheels" for those who are trying to work out their workflow procedures before moving on to Maximum mode.
Maximum provides the strictest NENR protection for business, legal, government and industry requirements, comparable to IBM N series "Compliance SnapLock" mode, for data that traditionally were written to WORM optical media. Data cannot be deleted until the retention period ends. Retention periods of individual files and objects can be increased, but not decreased. Retention Hold (often referred to as Litigation Hold) can be used to keep a set of related data even longer in specific circumstances.
You can decide to upgrade your protection after data is written to a collection. Basic mode can be upgraded to Intermediate mode, for example, or Intermediate mode upgraded to Maximum.
To keep things simple, v1.1 of the Information Archive supports only two industry standard protocols: NFS and SSAM API. The NFS option allows standard file commands to read/write data. The System Storage Archive Manager (SSAM) API allows smooth transition from earlier IBM System Storage DR550 deployments. With this announcement, IBM will [discontinue selling the DR550 DR2 models].
As we say here at IBM, "Today is the best day to stop using EMC Centera." For more information, see the
IBM [Announcement Letter].
Am I dreaming? On his Storagezilla blog, fellow blogger Mark Twomey (EMC) brags about EMC's standard benchmark results, in his post titled [Love Life. Love CIFS.]. Here is my take:
A Full 180 degree reversal
For the past several years, EMC bloggers have argued, both in comments on this blog, and on their own blogs, that standard benchmarks are useless and should not be used to influence purchase decisions. While we all agree that "your mileage may vary", I find standard benchmarks are useful as part of an overall approach in comparing and selecting which vendors to work with, and which architectures or solution approaches to adopt, and which products or services to deploy. I am glad to see that EMC has finally joined the rest of the planet on this. I find it funny this reversal sounds a lot like their reversal from "Tape is Dead" to "What? We never said tape was dead!"
Impressive CIFS Results
The Standard Performance Evaluation Corporation (SPEC) has developed a series of NFS benchmarks, the latest, [SPECsfs2008] added support for CIFS. So, on the CIFS side, EMC's benchmarks compare favorably against previous CIFS tests from other vendors.
On the NFS side, however, EMC is still behind Avere, BlueArc, Exanet, and IBM/NetApp. For example, EMC's combination of Celerra gateways in front of V-Max disk systems resulted in 110,621 OPS with overall response time of 2.32 milliseconds. By comparison, the IBM N series N7900 (tested by NetApp under their own brand, FAS6080) was able to do 120,011 OPS with 1.95 msec response time.
Even though Sun invented the NFS protocol in the early 1980s, they take an EMC-like approach against standard benchmarks to measure it. Last year, fellow blogger Bryan Cantrill (Sun) gives his [Eulogy for a Benchmark]. I was going to make points about this, but fellow blogger Mike Eisler (NetApp) [already took care of it]. We can all learn from this. Companies that don't believe in standard benchmarks can either reverse course (as EMC has done), or continue their downhill decline until they are acquired by someone else.
(My condolences to those at Sun getting laid off. Those of you who hire on with IBM can get re-united with your former StorageTek buddies! Back then, StorageTek people left Sun in droves, knowing that Sun didn't understand the mainframe tape marketplace that StorageTek focused on. Likewise, many question how well Oracle will understand Sun's hardware business in servers and storage.)
What's in a Protocol?
Both CIFS and NFS have been around for decades, and comparisons can sometimes sound like religious debates. Traditionally, CIFS was used to share files between Windows systems, and NFS for Linux and UNIX platforms. However, Windows can also handle NFS, while Linux and UNIX systems can use CIFS. If you are using a recent level of VMware, you can use either NFS or CIFS as an alternative to Fibre Channel SAN to store your external disk VMDK files.
The Bigger Picture
There is a significant shift going on from traditional database repositories to unstructured file content. Today, as much as [80 percent of data is unstructured]. Shipments this year are expected to grow 60 percent for file-based storage, and only 15 percent for block-based storage. With the focus on private and public clouds, NAS solutions will be the battleground for 2010.
So, I am glad to see EMC starting to cite standard benchmarks. Hopefully, SPC-1 and SPC-2 benchmarks are forthcoming?
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.
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.
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.
