Continuing my coverage of the [IBM System x and System Storage Technical Symposium], I thought I would start with some photos. I took these with cell phone, and without realizing how much it would cost, uploaded them to Flickr at international data roaming rates. Oops!
Here are some of the banners used at the conference. Each break-out session room was outfitted with a "Presentation Briefcase" that had everything a speaker might need, including power plug adapters and dry-erase markers for the whiteboard. What a clever idea!
Here is a recap of the last and final day 3:
Understanding IBM's Storage Encryption Options
Special thanks to Jack Arnold for providing me his deck for this presentation. I presented IBM's leadership in encryption standards, including the [OASIS Key Management Interoperability Protocol] that allows many software and hardware vendors to interoperate. IBM offers the IBM Tivoli Key Lifecycle Manager (TKLM v2) for Windows, Linux, AIX and Solaris operating systems, and the IBM Security Key Lifecycle Manager (v1.1) for z/OS.
Encrypting data at rest can be done several ways, by the application at the host server, in a SAN-based switch, or at the storage system itself. I presented how IBM Tivoli Storage Manager, the IBM SAN32B-E4 SAN switch, and various disk and tape devices accomplish this level of protection.
NAS @ IBM
Rich Swain, IBM Field Technical Sales Specialist for NAS solutions, provided an overview of IBM's NAS strategy and the three products: Scale-Out Network Attached Storage (SONAS), Storwize V7000 Unified, and N series.
IBM System Networking Convergence CEE/DCB/FCoE
Mike Easterly, IBM Global Field Marketing Manager for IBM System Networking, presented on Network convergence. He wants to emphasize that "Convergence is not just FCoE!" rather it is bringing together FCoE with iSCSI, CIFS, NFS and other Ethernet-based protocols. In his view, "All roads lead to Ethernet!"
There are a lot new standards that didn't exist a few years ago, such as PCI-SIG's Single Root I/O Virtualization [SR-IOV], Virtual Ethernet Port Aggregator [VEPA], and [VN-Tag], Data Center Bridging [DCB], Layer-2 Multipath [L2MP], and my favorite: Transparent Interconnect of Lots of Links [TRILL].
Last year, IBM acquired Blade Network Technologies (BNT), which was the company that made IBM BladeCenter's Advanced Management Module (AMM) and BladeCenter Open Fabric Manager (BOFM). BNT also makes Ethernet switches, so it has been merged with IBM's System Storage team, forming the IBM System Storage and Networking team. Most of today's 10GbE is either fiber optic, Direct Attach Copper (DAC) that supports up to 8.5 meter length cables, or 10GBASE-T which provides longer distances of twisted pair. IBM's DS3500 uses 10GBASE-T for its 10GbE iSCSI support.
Last month, IBM announced 40GbE! I missed that one. The IT industry also expects to deliver 100GbE by 2013. For now, these will be used as up-links between other switches, as most servers don't have the capacity to pump this much data through their buses. With 40GbE and 100GbE, it would be hard to ignore Ethernet as the common network standard to drive convergence.
Fibre Channel, such as FCP and FICON, are still the dominant storage networking technology, but this is expected to peak around 2013 and start declining thereafter in favor of iSCSI, NAS and FCoE technologies. Already the enhancements like "Priority-based Flow Control" made to Ethernet to support FCoE have also helped out iSCSI and NAS deployments as well.
The iSCSI protocol is being used with Microsoft Exchange, PXE Boot, Server virtualization hypervisors like VMware and Hyper-V, as well as large Database and OLTP. IBM's SVC, Storwize V7000, XIV, DS5000, DS3500 and N series all support iSCSI.
IBM's [RackSwitch] family of products can help offload traffic at $500 per port, compared to traditional $2000 per port for IBM SAN32B or Cisco Nexus5000 converged top-of-rack switches.
IBM's System Networking strategy has two parts. For Ethernet, offer its own IBM System Networking product line as well as continue its partnership with Juniper Networks. For Fibre Channel and FCoE, continue strategic partnerships with Brocade and Cisco. IBM will lead the industry, help drive open standards to adopt Converged Enhanced Ethernet (CEE), provide flexibility and validate data center networking solutions that work end-to-end.
IBM Storage Strategy for the Smarter Computing Era
I presented this session on Thursday morning. It is a session I give frequently at the IBM Tucson Executive Briefing Center (EBC). IBM launched [Smarter Computing initiative at IBM Pulse conference]. My presentation covered the role of storage in Business Analytics, Workload Optimized Systems, and Cloud Computing.
Layer 8: Cloud Computing and the new IT Delivery Model
Ed Batewell, IBM Field Technical Support Specialist, presented this overview on Cloud Computing. The "Layer 8" is a subtle reference to the [7-layer OSI Model] for networking protocols. Ed cites insights from the [2011 IBM Global CIO Survey]. Of the 3000 companies surveyed, 60 percent plan to use or deploy clouds. In USA, 70 percent of CIOs have significant plans for cloud within the next 3-5 years. These numbers are double the statistics gleamed from the 2009 Global CIO survey. Clouds are one of IBM's big four initiatives, expecting to generate $7 Billion USD annual revenues by 2015.
IBM is recognized in the industry as one of "Big 5" vendors (Google, Yahoo, Microsoft, and Amazon round out the rest). As such, IBM has contributed to the industry a set of best practices known as the [Cloud Computing Reference Architect (36-page document)]. As is typical for IBM, this architecture is end-to-end complete, covering the three main participants for successful cloud deployments:
Consumers: the people and systems that use cloud computing services
Providers: the people, infrastructure and business operations needed to deliver IT services to consumers
Developers: the people and their development tools that create apps and platforms for cloud computing
IBM is working hard to eliminate all barriers to adoption for Cloud Computing. [Mirage image management] can patch VM images offline to address "Day 0" viruses. [Hybrid Cloud Integrator can help integrate new Cloud technologies to legacy applications. [IBM Systems Director VMcontrol] can manage VM images from z/VM on the mainframe, to PowerVM on UNIX servers, to VMware, Microsoft, Xen and KVM for x86 servers. IBM's [Cloud Service Provider Platform (CSP2)] is designed for Telecoms to offer Cloud Computing services. IBM CloudBurst is a "Cloud-in-a-Can" optimized stack of servers, storage and switches that can be installed in five days and comes in various "tee-shirt sizes" (Small, Medium, Large and Extra Large), depending on how many VMs you want to run.
Ed mentioned that companies trying to build their own traditional IT applications and environments, in an effort to compete against the cost-effective Clouds, reminded him of Thomas Thwaites' project of building a toaster from scratch. You can watch the [TED video, 11 minutes]:
An interesting project is [Reservoir] which IBM is working with other industry leaders to develop a way to seamlessly migrate VMs from one location to another, globally, without requiring shared storage, SAN zones or Ethernet subnets. This is similar to how energy companies buy and sell electricity to each other, as needed, or the way telecommunications companies allow roaming acorss each others networks.
IBM System Networking - Convergence
Jeff Currier, IBM Executive Consultant for the new IBM System Networking group, presented this session on Network Convergence. Storage is expected to grow 44x, from 0.8 [Zettabytes] in 2009, to 35 Zetabytes by the year 2020. The role of the network is growing in importance. IBM refers to this converged loss-less Ethernet network as "Convergence Enhanced Ethernet" (CEE), which Cisco uses the term "Data Center Ethernet" (DCE), and the rest of the industry uses "Data Center Bridging" (DCB).
To make this happen, we need to replace Spanning Tree Protocol [STP] that eliminates walking in circles in a multi-hop network configuration, with a new Layer 2 Multipathing (L2MP) protocol. The two competing for the title are Shortest Path Bridging (IEEE 802.1aq) and Transparent Interconnect of Lots of Links (IETF TRILL).
All roads lead to Ethernet. While FCoE has not caught on as fast as everyone hoped, iSCSI has benefited from all the enhancements to the Ethernet standard. iSCSI works in both lossy and lossless versions of Ethernet, and seems to be the preferred choice for new greenfield deployments for Small and Medium sized Businesses (SMB). Larger enterprises continue to use Fibre Channel (FCP and FICON), but might use single-hop FCoE from the servers to top-of-rack switches. Both iSCSI and FCoE scale well, but FCoE is considered more efficient.
IBM has a strategy, and is investing heavily in these standards, technologies, and core competencies.
I always try to catch a session from Jim Blue, who works in our "SAN Central" center of competency team. This session was a long list of useful hints and tips, based on his many years of experience helping clients.
SAN Zoning works by inclusion, limiting the impact of failing devices. The best approach is to zone by individual initiator port. The default policy for your SAN zoning should be "deny".
Ports should be named to identify who, what, where and how.
While many people know not to mix both disk and tape devices on the same HBA, Jim also recommends not mixing dissimilar disks, test and production, FCP and FICON.
The sweet spot is FOUR paths. Too many paths can impact performance.
When making changes to redundant fabrics, make changes to the first fabric, then allow sufficient time before making the same changes to the other fabric.
Use software tools like Tivoli Storage Productivity Center (Standard Edition) to validate all changes to your SAN fabric.
Do not mix 62.5 and 50.0 micron technology.
Use port caps to disable inactive ports. In one amusing anecdote, he mention that an uncovered port was hit by sunlight every day, sending error messages that took a while to figure out.
Save your SAN configuration to non-SAN storage for backup
Consider firmware about two months old to be stable
Rule of thumb for estimating IOPS: 75-100 IOPS per 7200 RPM drive, 120-150 IOPS per 10K RPM drive, and 150-200 IOPS per 15K RPM drive.
Decide whether your shop is just-in-time or just-in-case provisioning. Just-in-time gets additional capacity on demand as needed, and just-in-case over-provisions to avoid scrambling last minute.
Avoid oversubscribing your inter-switch links (ISL). Aim for around 7:1 to 10:1 ratio.
Don't go cheap on bandwidth between sites for long-distance replication
Next Generation Network Fabrics - Strategy and Innovations
Mike Easterly, IBM Director of Global Field Marketing, presented IBM System Networking strategy, in light of IBM's recent acquisition of Blade Network Technologies (BNT). BNT is used in 350 of the Fortune 500 companies, and is ranked #2 behind Cisco in sales of non-core Ethernet switches (based on number of units sold).
Based on a recent survey, companies are upgrading their Ethernet networks for a variety of reasons:
56 percent for Live Partition Mobility and VMware Vmotion
45 percent for integrated compute stacks, like IBM CloudBurst
43 percent for private, public and hybrid cloud computing deployments
40 percent for network convergences
Many companies adopt a three-level approach, with core directors, distribution switches, and then access switches at the edge that connect servers and storage devices. IBM's BNT allows you to flatten the network to lower latency by collapsing the access and distribution levels into one.
IBM's strategy is to focus on BNT for the access/distribution level, and to continue its strategic partnerships for the core level.
IBM BNT provides better price/performance and lower energy consumption. To help with hot-aisle/cold-aisle rack deployments, IBM BNT provides both F and R models. F models have ports on the front, and R models have ports in the rear.
IBM BNT supports virtual fabric and HW-offload iSCSI traffic, and future-enabled for FCoE. Support for TRILL (transparent interconnect of lots of links) and OpenFlow will be implemented through software updates to the switches.
While Cisco Nexus 1000v is focused on VMware Enterprise Plus, IBM BNT's VMready works with VMware, Hyper-V, Linux KVM, XEN, OracleVM, and PowerVM. This allows single pane of management of VMready and ESX vSwitches.
In preparation for Converged Enhanced Ethernet (CEE), IBM BNT will provide full 40GbE support sometime next year, and offer switches that support 100GbE uplinks. IBM offers extended length cables, including passive SFP+ DAC at 8.5 meters, and 10Gbase-T Cat7 cables up to 100 meters.
Inter-datacenter Workload Mobility with VMware vSphere and SAN Volume Controller (SVC)
This session was co-presented between Bill Wiegand, IBM Advanced Technical Services, and Rawley Burbridge, IBM VMware and midrange storage consultant. IBM is the leader in storage virtualization product (SVC), and is the leading reseller of VMware.
Like MetroCluster on IBM N series, or EMC's VPLEX Metro, the IBM SAN Volume Controller can support a stretched cluster across distance that allows virtual machines to move seamlessly from one datacenter to another. This is a feature IBM introduced with SVC 5.1 back in 2009. This can be used for PowerVM Live Partition Mobility, VMware vMotion, and Hyper-V Quick Migration.
SVC stretched cluster can help with both Disaster Avoidance and Disaster Recovery. For Disaster Avoidance, in anticipation of an outage, VMs can be moved to the secondary datacenter. For Disaster Recover, additional automation, such as VMware High Availability (HA) is needed to restart the VMs at the secondary datacenter.
IBM stretched cluster is further improved with a feature called Volume Mirroring (formerly vDisk Mirroring) which creates two physical copies of one logical volume. To the VMware ESX hosts, there is only one volume, regardless of which datacenter it is in. The two physical copies can be on any kind of managed disk, as there is no requirement or dependency of copy services on the back-end storage arrays.
Another recent improvement is the idea of spreading the three quorum disks to three different locations or "failure domains". One in each data center, and a third one in a separate building, somewhere in between the other two, perhaps.
Of course, there are regional disasters that could affect both datacenters. For this reason, SVC stretched cluster volumes can be replicated to a third location up to 8000 km away. This can be done with any back-end disk arrays, as again there is not requirement for copy services from the managed devices. SVC takes care of it all.
Networking is going to be very important for a variety of transformational projects going forward in the next five years.
Optimizing Storage Infrastructure for Growth and Innovation
This session started off with my former boss, Brian Truskowski, IBM General Manager of System Storage and Networking.
We've come a long way in storage. In 1973, the "Winchester Drive" was named after the famous Winchester 3030 rifle. The disk drive was planning to have two 30MB platters, hence the name. When it finally launched, it would have two 35MB platters, for a total raw capacity of 70MB.
Today, IBM announced the verison 6.2 of SAN Volume Controller with support for 10GbE iSCSI. Since 2003, IBM has sold over 30,000 SAN Volume Controllers. An SVC cluster can now manage up to 32PB of disk storage.
IBM also announced new 4TB tape drive (TS1140), LTFS Library Edition, the TS3500 Library Connector, improved TS7600 and TS7700 virtual tape libraries, enhanced Information Archive for email, files and eDiscovery, new Storwize V7000 hardware, new Storwize Rapid Application bundles, new firmware for SONAS and DS8000 disk systems, and Real-Time Compression support for EMC disk systems. I plan to cover each of these in follow-on posts, but if you can't wait, here are [links to all the announcements].
Customer Testimonial - CenterPoint Energy
"CenterPoint is transforming its business from being an energy distribution company that uses technology, to a technology company that distributes energy."
-- Dr. Steve Pratt, CTO of CenterPoint Energy
The next speaker was Dr. Steve Pratt is CTO of [CenterPoint Energy]. CenterPoint is 110 years old (older than IBM!) energy company that is involved in electricity, gasoline distribution, and natural gas pipeline. CenterPoint serves Houston, Texas (the fourth largest city in the USA) and surrounding area.
CenterPoint are transforming to a Smart Grid involving smart meters, and this requires the best IT infrastructure you can buy, including IBM DS8000, XIV and SAN Volume Controller disk systems, IBM Smart Analytics System, Stream Analytics, IBM Virtual Tape Library, IBM Tivoli Storage Manager, and IBM Tivoli Storage Productivity Center.
Dr. Pratt has seen the transition of information over the years:
Data Structure, deciding how to code data to record it in a structured manner
Information Reporting, reporting to upper management what happened
Intelligence Aggregation, finding patterns and insight from the data
Predictive Analytics, monitoring real-time data to take pro-active steps
Autonomics, where automation and predictive analysis allows the system to manage itself
What does the transition to a Smart Grid mean for their storage environment? They will go from 80,000 meter reads, to 230,400,000 reads per day. Ingestion of this will go from MB/day to GB/sec. Reporting will transition to real-time analytics.
Dr. Pratt prefers to avoid trade-offs. Don't lose something to get something else. He also feels that language of the IT department can help. For example, he uses "Factor" like 25x rather than percent reduction (96 percent reduced). He feels this communicates the actual results more effectively.
Today's smarter consumers are driving the need for smarter technologies. Individual consumers and small businesses can make use of intelligent meters to help reduce their energy costs. Everything from smart cars to smart grids will need real-time analytics to deal with the millions of events that occur every day.
IBM's Data Protection and Retention Story
Brian Truskowski came back to provide the latest IBM messaging for Data Protection and Retention (DP&R). The key themes were:
Stop storing so much
Store more with what's on the floor
Move data to the right place
IBM announced today that the IBM Real-Time Compression Appliances now support EMC gear, such as EMC Celerra. While some of the EMC equipment have built-in compression features, these often come at a cost of performance degradation. Instead, the IBM Real-Time compression can offer improved performance as well as 3x to 5x reduction in storage capacity.
OVer 70 percent of data on disk has not be accessed in the last 90 days. IBM Easy Tier on the DS8700 and DS8800 now support FC-to-SATA automated tiering.
IBM is projecting that backup and archive storage will grow at over 50 percent per year. To help address this, IBM is launching a new "Storage Infrastructure Optimization" assessment. All attendees at today's summit are eligible for a free assessment.
Analytics are increasing the value of information, and making it more accessible to the average knowledge worker. The cost of losing data, as well as the effort spent searching for information, has skyrocketed. Users have grown to expect 100 percent uptime availability.
An analysis of IT environments found that only 55 percent was spent on revenue-producing workloads. The remaining 45 percent was spent on Data Protection and Retenion. That means that for every IT dollar spent on projects to generate revenue, you are spending another 90 cents to protect it. Imagine spending 90 percent of your house payments for homeowners' insurance, or 90 percent of your car's purchase price for car insurance.
IBM has organized its solutions into three categories:
Hyper-Efficient Backup and Recovery
Continuous Data Availability
What would it mean to your business if you could shift some of the money spent on DP&R over to revenue-producing projects instead? That was the teaser question posed at the end of these morning sessions for us to discuss during lunch.
Every January, we look back into the past as well as look into the future for trends to watch for the upcoming year. Ray Lucchesi of Silverton Consulting has a great post looking back at the [Top 10 storage technologies over the last decade]. I am glad to see that IBM has been involved with and instrumental in all ten technologies.
Looking into the future, Mark Cox of eChannel has an article [Storage Trends to Watch in 2011], based on his interviews with two fellow IBM executives: Steve Wojtowecz, VP of storage software development, and Clod Barrera, distinguished engineer and CTO for storage. Let's review the four key trends:
Cloud Storage and Cloud Computing
No question: Cloud Computing will be the battleground of the IT industry this decade. I am amused by the latest spate of Microsoft commercials where problems are solved with someone saying "...to the cloud". Riding on the coat tails of this is "Cloud Storage", the ability to store data across an Internet Protocol (IP) network, such as 10GbE Ethernet, in support of Cloud Computing applications. Cloud Storage protocols in the running include NFS, CIFS, iSCSI and FCoE.
Mark writes "..vendors who aren't investing in cloud storage solutions will fall behind the curve."
Economic Downturn forces Innovation
The old British adage applies: "Necessity is the mother of invention." The status quo won't do. In these difficult economic times, IT departments are running on constrained budgets and staff. This forces people to evaluate innovative technologies for storage efficiency like real-time compression and data deduplication to make better use of what they currently have. It also is forcing people to take a "good enough" attitude, instead of paying premium prices for best-of-breed they don't really need and can't really afford.
IT Service Management
Companies are getting away from managing individual pieces of IT kit, and are focusing instead on the delivery of information, from the magnetic surface of disk and tape media, to the eyes and ears of the end users. The deployment mix of private, hybrid and public clouds makes this even more important to measure and manage IT as a set of services that are delivered to the business. IT Service Management software can be the glue, helping companies implement ITIL v3 best practices and management disciplines.
Smarter Data Placement
A recent survey by "The Info Pro" analysts indicates that "managing storage growth" is considered more critical than "managing storage costs" or "managing storage complexity".
This tells me that companies are willing to spend a bit extra to deploy a tiered information infrastructure if it will help them manage storage growth, which typically ranges around 40 to 60 percent per year. While I have discussed the concept of "Information Lifecycle Management" (ILM), for the past four years on this blog, I am glad to see it has gone mainstream, helped in part with automated storage tiering features like IBM System Storage Easy Tier feature on the IBM DS8000, SAN Volume Controller and Storwize V7000 disk systems. Not all data is created equal, so the smart placement of data, based on the business value of the information contained, makes a lot of sense.
These trends are influencing what solutions the various different vendors will offer, and will influence what companies purchase and deploy.
