This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here's my recap of the afternoon sessions of Day 2.
IBM Spectrum Protect deep dive into Container Storage Pools
Ron Henkhaus, IBM Certified Consulting IT Specialist, presented the new Spectrum Protect concept of "Container Pools" that can either be "Directory Pools" on SAN or NAS-based disk storage, or "Cloud Pools". Container pools can contain deduplicated and non-dedupe data.
Ron cautioned that directory pools should not be placed on the same file system as your Spectrum Protect database or logs. Also, best practice for any directory pool is to assign an "overflow" pool to any non-directory pool, such as disk, tape or cloud container.
Cloud pools can use either OpenStack Swift, V1 Swift, Amazon S3 protocol, Amazon Web Services, IBM Bluemix, and IBM Cloud Object Storage. You can pre-define the vaults and buckets in the configuration.
For off-premises Cloud pools, the data is encrypted by default. For other container pools, encryption is optional. Performance to Cloud pools have been improved by using "accelerator storage", basically a disk cache to collect data before sending over to the Cloud pool. Backups to Cloud pools can reach 8 TB per hour. Restore times varies from 500 to 1500 GB per hour.
Container Pools were designed for the new "Deduplication 2.0" feature introduced in version 7. Traditional Dedupe 1.0 to Device Class FILE is still available, but not recommended.
Version 7.1.6 changed the compression algorithm from LZW to LZ4. In all cases, Spectrum Protect performs these actions in this order: deduplication, compression, encryption. Data that is encrypted by the Spectrum Protect client is therefore not deduped.
The "Protect Storage Pool" command can replicate a directory pool to either a remote directory pool or Cloud pool. In addition to this remote replication, you can copy a directory pool to tape to offer air-gap protection against ransomware. Such tapes are considered part of the "Copy Container Pool". In the event of directory pool corruption, the data can be repaired from either replication or tape.
IBM Aspera can now be used for replication, using SSL and AES-128 bit encryption. If your latency is greater than 50 msec, and have more than 0.5 percent packet loss, Aspera might help. This is available for Linux on x86 platforms running v7.1.6 or higher.
For existing customers, IBM Spectrum Protect allows you to convert your FILE, VTL and TAPE device class pools to directory or Cloud pools.
Introduction to IBM Cloud Object Storage (powered by Cleversafe)
In 2015, IBM acquired Cleversafe, recognized as the #1 Object Storage vendor. Their flagship product was officially renamed to the IBM Cloud Object Storage System, which some abbreviate informally as IBM COS. IBM offers the IBM Cloud Object Storage System in three ways: as software, as pre-built systems, and as a cloud service on IBM Bluemix (formerly known as SoftLayer).
Since then, IBM has been busy integrating IBM COS into the rest of the storage portfolio. I explained how IBM COS can be used for all kinds of static-and-stable data, but not suited for frequently changed data, such as Virtual machines or Databases.
Object storage can be access via NFS or SMB NAS-protocols using a gateway product, like IBM Spectrum Scale, or those from third-party partners like Ctera, Avere, Nasuni or Panzura. It can also be used as an alternative to tape for backup copies, and is already supported by the major backup software like IBM Spectrum Protect, Commvault Simpana, or Veritas NetBackup.
While other cloud service providers have offered data storage in the cloud, this new offering also allows hybrid configurations with geographically dispersed erasure coding.
Unlike RAID which protects against the loss of one or two drives, erasure coding can protect against a larger number of concurrent failures. For example, using an Information Dispersal Algorithm (IDA) of "7+5", where seven pieces of data are encoded on twelve independent disks, the system can lose up to five disk drives without losing any data.
Combining this with Geographically Dispersed Configuration across three or more sites means that you can lose an entire data center, four of the twelve disks, and still have instant full access to all of your data from eight drives at the other locations. In the graphic, you see two on-premise data centers combined with a third location in IBM SoftLayer.
New Generation of Storage Tiering: Simpler Management, Lower Costs, and Improved Performance
With ever changing amounts of storage, it is hard to find metrics that are consistent year to year. Fortunately, we found I/O density as the metric to focus my efforts, armed with real data from Intelligent Information Lifecycle Management (IILM) studies done at various clients. From that, I was able to talk about storage tiering on three fronts:
Storage tiering between Flash and disk. IBM FlashSystem and IBM Easy Tier on DS8000 and Spectrum Virtualize family for hybrid Flash-and-disk configurations.
Storage tiering between disk, tape, and Cloud. HSM and Information Lifecycle Management (ILM) on Spectrum Scale, Elastic Storage Server (ESS), Spectrum Archive and IBM Cloud Object Storage System.
Storage tiering automation across your entire environment. IILM studies can help identify a target mix of Tier 0, Tier 1, Tier 2 and Tier 3 storage. IBM Spectrum Storage Suite and the Virtual Storage Center (VSC) can recommend or perform the movement of LUNs to more appropriate tiers, based on age and I/O density measurements.
It's hard to say what the correct sequence of presentations should be. Some thought it might have been better for my talk on IBM Cloud Object Storage System prior to Ron's talk on Cloud container pools, but perhaps hearing Ron first helped drive more interest to my session.
I have been involved with Business Continuity and Disaster Recovery my entire career at IBM System Storage. However, with new workloads like Hadoop analytics and new Hybrid Cloud deployments, I thought it would be good to provide a refresh.
The need for Business Continuity and Disaster Recovery has increased recently due to (a) climate change caused by human activity, (b) ransomware and other cyber attacks, and (c) disgruntled employees.
Back in 1983, a task force of IBM clients at a GUIDE conference developed "Seven Business Continuity Tiers for Disaster Recovery", which I refer to as "BC Tiers". I divided the presentation into three sections:
Backup and Restore: BC tiers 1 through 3 are based on backup and restore methodologies. I explained how to backup Hadoop analytics data, all of the various options for IBM Spectrum Protect software, and how to encrypt the tape data that gets sent off premises.
Rapid Data Recovery: BC tiers 4 and 5 reduce the Recovery Point Objective (RPO) and Recovery Time Objective (RTO) with snapshots, database journal shadowing, and IBM Cloud Object Storage.
Continuous Operations: BC tiers 6 and 7 provide data replication mirroring across locations. I covered 2-site, 3-site and 4-site configurations.
IBM Spectrum Virtualize - How it works - Deep dive
Barry Whyte, IBM Master Inventor and ATS for Spectrum Virtualize, covered a variety of internal topics "under the hood" of Spectrum Virtualize. This covers the SAN Volume Controller (SVC), FlashSystem V9000, Storwize V7000 and V5000 products, as well as Spectrum Virtualize sold as software.
In version 7.7, IBM raised the limits. You can now have 10,000 virtual disks per cluster, rather than 2,048 per node-pair. Also, you can now have up to 512 compressed volumes per node-pair. With the new 5U-high 92-drive expansion drawers, Storwize V7000 can now support up to 3,040 drives, and Storwize V5030 can support up to 1,520 drives.
While each Spectrum Virtualize node has redundant components, the architecture is designed to handle entire node failure. The term "I/O Group" was created to refer to the node-pair of Spectrum Virtualize engines and the set of virtual disks it manages. This made sense when virtual disks were dedicated to a single node-pair. Now, virtual disks can be assigned to multiple node-pairs, dynamically adding or removing node-pairs as needed for each virtual disk.
However, even if you have a virtual disk assigned to multiple node-pairs, only one node-pair would manage its cache, causing all other node-pairs to coordinate I/O through the cache-owning node-pair. The other node-pairs are called "access I/O groups".
The architecture allows for linear scalability, double the number of nodes, and you double your performance. Some competitors use n-way caching across four or more nodes, and it is a semi-religious argument on the pros and cons of each approach. Barry feels the 2-way caching implemented by Spectrum Virtualize is the most effective and efficient for performance.
All of the nodes are connected over IP network, but there is one designated as a "config node", and one, often the same, as a "boss node".
A cluster can have up to three physical quorum disks (either drive or mDisk) and optionally up to five IP-based quorums. The IP-based is just a Java program that runs on any server or Cloud, provided it can respond within 80 msec.
Either IP-based or physical quorum can be used for "tie-breaking" a split-brain situations. In the event there is no "active" quorum, the administrator can now serve as the tie-breaker manually. Barry recommends for Storwize clusters, where physical quorum disks are attached to a single node-pair, that you have at least one IP-based quorum for tie-breaking.
However, only physical quorum can be used for T3 Recovery. T3 Recovery happens after power outages. All of the nodes update the quorum disk with critical information of all of the virtual mappings of blocks to volumes, and this is used when bringing up the nodes again.
To protect against one pool consuming all of the cache, Spectrum Virtualize will partition the cache, and prevent any one pool from consuming more than a certain percentage of the total cache. The percentage depends on the number of pools:
Number of Pools
Max percentage of any individual pool
5 or more
Barry explained how failover works in the event of node failure. There is voting involved, and the majority remains in the cluster. In the case of an even split, called a "split brain" situation, the quorum decides. Orphaned nodes in a node-pair go into write-through mode, since the cache is no longer mirrored.
The I/O forwarding layer has been split between upper and lower roles. The upper layer handles access I/O groups. The lower layer handles asymmetric access to drives, mDisks and arrays.
N-port ID Virtualization (NPIV) drastically improves multi-pathing. Perhaps one of the coolest improvements in awhile, NPIV allows us to assign "Virtual" WWPN to other ports. When an I/O sent to a single port fails, it retries one or more times again, then waits 30 seconds, and then invokes multi-pathing to find a completely different path to the data. With NPIV, when a port fails, its WWPN is re-assigned to a different port, so the retries are likely to be successful before having to wait 30 seconds!
Lastly, Barry covered the delicate art of Software upgrades. Software is rolled forward one node at a time, and the "cluster state" is maintained during this time.
Different presentations this week are at different technical levels. My session was meant to be an overview of the concepts of Business Continuity, independent of specific operating system platform, using specific IBM products to help illustrate specific examples. Barry's was a deep dive into a single product family.
IBM Spectrum Scale was formerly called GPFS and has been around since 1998. I am glad it was renamed, as GPFS suffered from "guilt by association" with other file systems, AFS, DFS, XFS, ZFS, and so on.
Spectrum Scale does so much more, supports volume, file and object level access, supports POSIX standards for Windows, AIX and Linux, support Hadoop and Spark with 100 percent compatible HDFS Transparency Connector, support NFS, SMB and iSCSI protocols, as well as OpenStack Swift and Amazon S3 object based access.
Initially designed for video streaming and High Performance Computing (HPC), IBM has extended its reach to work in a variety of workloads across different industries. More than 5,000 production systems are running at client locations.
IBM Spectrum Protect solution design: Server, Deduplication and Disaster Recovery decisions
Dan Thompson, IBM Storage Software Technical Sales Specialist, presented this session.
To make it easier to deploy, IBM Spectrum Protect now has a set of tested "blueprints" that are organized into small, medium and large. Find the one that fits your needs, and it will tell you exactly how the server should be configured. Dan recommends having a "test system" to try out new releases of IBM Spectrum Protect.
For multiple server configurations, Dan recommends adopting a standard naming convention, and to make use of Enterprise Configuration and server-side Client Option Sets. You may want to consider discrete instances for special non-backup functions, like library manager or Operations Center hub server, which allows you to upgrade more aggressively without affecting your backup clients.
If you plan to run multiple Spectrum Protect instances on the same VMware host, set the DBmemPercent to avoid having DB2 consume all of the memory, which will interfere with out Spectrum Protect instances.
For clustered servers, IBM supports Active/Passive, Active/Active, Many/One, and Many/Few configurations. You can mix and match these as needed.
For data spill remediation, consider NIST 800-88 data shredding. This depends on the type of storage media used.
IBM Spectrum Protect for Data Retention, formerly called System Storage Archive Manager (SSAM), offers For Non-erasable, Non-Rewriteable (NENR) enforced Immutability protection. (This used to be called Write-Once-Read-Many or WORM for short, but since WORM applies only to tape and optical media, and IBM Spectrum Protect now supports Flash, Disk, Object Storage and Cloud repositories, IBM has adopted the term NENR instead). Third party KPMG has certified IBM Spectrum Protect for Data Retention meets to their satisfaction the requirements for SEC 17a-4 regulations.
When sizing your server, Dan recommends that you always "over-size" it and grow into it. Use the published "Performance Optimization Guide" to help. Monitor the server and storage using OS and device specific monitoring, in combination with IBM Spectrum Protect reports.
If you are still on BC Tiers 1 or 2, transmitting tapes to a remote vaulting facility or secondary data center, consider upgrading to BC Tier 3 at least. This can be done via electronic vaulting to an Automated Tape Library (ATL), Virtual Tape Library (VTL) or IBM Cloud Object Storage, or a Cloud service provider such as IBM Bluemix or Amazon Web Services. This can be supplemented using DB2 HADR for the IBM Spectrum Protect database.
While Spectrum Protect server can run bare-metal or as a VM, the VM instance will not have support for FCP-based tape or Virtual Tape Library. Many people are moving off tape, especially VTL, and using native Disk, Directory or Cloud container pools instead.
Lastly, take advantage that Operations Center can view all Spectrum Protect servers across all locations. This can be helpful.
Enabling Mission Critical NoSQL workloads using IBM trillions of operations technology
TJ Harris, from the IBM Storage CTO office, and Scott Brewer, FlashSystem Team Lead, co-presented this session.
They gave a background on NoSQL, the most popular being MongoDB. The IT industry estimates that NoSQL will grow 38 percent CAGR from 2015-2020.
The problem occurs when NoSQL applications go through a full file system stack to work with low-latency devices like Flash, especially when the writes are small, often just a few dozen bytes to 100 KB. Fortunately, IBM Research has created the "Trillions of Operations" project to explore ways to take reduce the software stack, and make use of NVMe protocol.
The top three challenges for NoSQL deployments are: (a) Cost, (b) Data management and retention, and (c) Data relevancy.
To enable innovation, MongoDB offers a "Storage Engine API" that allows others to compete at this space. Currently MMAP v1 and WiredTiger are supported. IBM Research implemented its "Trillion Operations" project as a plug-in to this API, optimized for high rates of ingest for data. Compared to Facebook's RocksDB, IBM was 14x faster write, and 2.1x faster read.
Another challenge is coordinate backups and disaster recovery when applications mix traditional RDBMS with these new NoSQL databases.
The week is nearly over, and I can see the light at the end of the tunnel. Everyone had a great time last night's event at the Universal City Walk and Blue Man Group.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here is my recap of the sessions on the morning of Day 4.
Configurable IBM Spectrum Scale
Kent Koeninger presented IBM Spectrum Scale software, which Kent refers to as "Configurable Spectrum Scale" (or CSS for short), as opposed to the pre-built system known as Elastic Storage Server (ESS).
Why choose CSS versus ESS? Lower entry price. You can start with just two single-socket servers and a drawer of disk.
IBM Spectrum Scale was formerly called IBM General Parallel File System (GPFS). Many who tried earlier versions of GPFS found it difficult to configure, because it only had a command line interface. Now, Spectrum Scale has a fully-functional GUI, and clients have been able to install and configure Spectrum Scale in just 30 minutes!
How big can Spectrum Scale grow? As much as your budget can afford! With an architecture that can support YottaBytes of data and 900 quintillion files, you won't hit any limits anytime soon.
There are some unique capabilities of ESS not available in CSS. For example, ESS offers Spectrum Scale Native RAID (erasure coding) with fast rebuild times, and ESS is certified for SAP HANA. You can combine any combination of CSS and ESS in the same Spectrum Scale to create a "data lake" for mixed workloads.
A good use case for Spectrum Scale, either CSS or ESS, is backup. Kent explained why it is an excellent option to store backups with enterprise backup software such as IBM Spectrum Protect or Commvault.
VersaStack - Hybrid Cloud like no other
This session was jointly presented by Chris Vollmar, IBM Storage Architect, and Brent Anderson, Cisco Global Consulting Systems Engineer. IBM and Cisco have been partners for more than 25 years.
VersaStack combines Cisco UCS x86 servers, Cisco Nexus and MDS switches, and IBM FlashSystem or Spectrum Virtualize storage.
What if you have a SAN Infrastructure built entirely from IBM b-type or Brocade-based switches? Cisco supports their SAN switches for this, but nobody has tested VersaStack in this combination, and UCS Director does not manage this combination, so IBM does not support this. Instead, for this situation, IBM recommends doing external connection via Ethernet, or using direct-attach configurations.
The Cisco Validated Design spends four months testing, and gives you bulletproof process to deploy the solution.
There is a difference between Cisco UCS Manager and UCS Director. UCS Manager is available at no additional charge, but only manages the Cisco x86 servers. UCS Director is optionally extra priced, and manages Cisco servers, Cisco networking, and IBM Spectrum Virtualize storage.
Brent explained the benefits of UCS Management through policies and profiles.
Chris covered Cisco CloudCenter, which the Cisco team shortens to just "C3". IBM Spectrum Copy Data Management can be used to move snapshots of data between on-premises and off-premises Cloud to help in Hybrid Cloud configurations.
How to Design an IBM Spectrum Scale solution
Tomer Perry, IBM Spectrum Scale I/O Development, presented this session.
For those who want to bring up a quick IBM Spectrum Scale environment to play around with, you can do this in as little as 30 minutes. But to design a mission critical deployment, additional requirements may need to be addressed. You may need to consult with not just storage admins, but also application owners, network admins and security personnel.
Large companies have hundreds or thousands of applications, so Tomer recommends to group these into "Workload families", based on data set types, access patterns and performance requirements. For NAS take-out, 80 percent of NAS I/O is "get attribute" that can easily be served directly from cache memory.
For each workload family, you may need to decide on snapshots, quotas, namespace (bind mounts, symlinks, etc.), security (ACL, encryption), estimated capacity, replication BC/DR, backup and ILM requirements.
Unless this is completely greenfield deployment, the existing infrastructure needs to be evaluated. This includes the LAN and WAN network topology, name resolution (DNS), time services (NTP), Authentication (AD, LDAP, NIS, Keystone), Keyserver (IBM SKLM), Monitoring and Migration requirements.
Tomer suggests designing the environment in this order: Cluster, File System, Storage Pools, Fileset, Replication, and finally Monitoring.
Generally, you need three NSD servers per cluster. For those licensing Spectrum Scale Standard Edition by the socket, you may be tempted to put everything into one big cluster. The new capacity-based Spectrum Scale Data Management Edition eliminates that concern, so Tomer recommends having separate computer clusters and storage clusters, connected by cross-cluster mount. All nodes in a cluster are considered an "ssh" administration domain.
A single Spectrum Control namespace can support up to 256 file systems. There are various reasons to have multiple file systems: block size, backup/recovery, snapshot, quotas, and cross-cluster isolation. If a file system gets corrupted, it will not affect other file systems. In an internal test, an "fsck" on 1 billion, 1 PB of data file system took only 30 minutes to repair.
Storage Pool design can separate metadata from content, and workloads can be separated to different storage media. With ILM, HSM and TCT, you can move colder data to Cloud, Object Storage, Spectrum Protect or Spectrum Archive.
Filesets are tree branches for each file system. IBM Spectrum Scale supports both dependent and independent filesets. Filesets can be used for Non-erasable, Non-Rewriteable (NENR) Immutability, policies, quotas, snapshots. Consider using a fileset instead of carving off a new file system.
Spectrum Scale offers both synchronous and asynchronous replication. For Synchronous, the ReadReplicaPolicy can be set to default, local or fastest. For Asynchronous, there are a variety of AFM modes (Read-only, Local-Update, Single-Writer, Independent-Writer, and Disaster Recovery). You may need to decide if your AFM gateways are dedicated or collocated. You will need to tune your TCP buffers for WAN performance to get the RPO you desire.
The nice thing about IBM solutions is that you can start small, and grow big. In all of these examples above, IBM offers sizes to match nearly any IT budget.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here's my recap of the sessions of Day 3.
Ethernet-only SANs -- Myth or Reality?
Anuj Chandra, IBM Advisory Engineer, presented an excellent overview of Ethernet-based SANs. He started with a quick history of Ethernet, starting with Robert Metcalfe's original drawing for his concept.
In the past, Ethernet was used for email and message transfer, and so dropped packets were tolerated. However, with the use of Ethernet for SANs, many standards have been adopted to make Ethernet networks more robust. These meet requirements for Flow Control, Congestion management, low latency, data integrity and confidentiality, network isolation, and high availability.
These standards are known as IEEE 802.1Q "Data Center Bridging", including 8012.Qbb Priority Flow Control, 802.1Qaz Enhanced Transmission Selection, 802.1Qau Congestion Notification. There is also the IETF Transparent Interconnection of Lots of Links (TRILL) to replace Spanning Tree Protocol (STP). All of these features are negotiated between endpoints server and storage. Ethernet that supports these new standards is often referred to as "Converged Ethernet" since it handles both traditional email/message traffic as well as SAN data traffic.
In addition to 1GbE and 10GbE, we now have 2.5, 5, 20, 40, 50, 100 Gb Ethernet speeds. By 2020, Anuj estimates over half of all Ethernet ports will be 25 GbE or faster. Amazingly, some of these can work on existing 10BASE-T cables.
Anuj also covered Remote Direct Memory Access (RDMA), and the RDMA-capable Network Interface Cards (RNIC) that support them. In one chart, shown here, Anuj explained Infiniband, RDMA over Converged Ethernet (RoCE) and RoCE v2, and Internet Wide Area RDMA Protocol (iWARP).
While many of these enhancements were intended for Fibre Channel over Ethernet (FCoE), the beneficiary has been iSCSI. Now there is iSCSI Extensions for RDMA (iSER) to take even more advantage of these changes, and can work with Infiniband, RoCE or iWARP. All of these networks can also be used as the basis for NVMe over Fabric (NVMeOF).
Ethernet is the backbone of Cloud usage, and IBM is well positioned to take advantage of these new networking technologies.
Digital Video Surveillance solutions for extended video evidence protection
Dave Taylor, IBM Executive Architect for Software Defined Storage solutions, presented this session on Digital Video Surveillance (DVS).
Most video surveillance is either analog-based, going to standard VHS tapes, or file-based. Sadly, security guards that watch live camera feeds lose their attention span after 22 minutes.
There are an estimated 72 million cameras globally, with 1.5 million more every year.
City governments spend 57 percent of their budget on "public safety". This can include body cams for police departments. Taser International, now called AXON, dominates the body-cam market.
City budgets may not be prepared to store all of this video content into a cloud that complies with Criminal Justice Information Services (CJIS) standards. These Cloud services tend to be more expensive, as the videos must be treated as evidence, tamper-proof, and with appropriate chain of custody.
DVS is not just storing movies. IBM offers Intelligent Video Analytics. It is important to be able to derive insight and actionable response.
Storage capacity adds up quickly. Standard 1080p (1920 by 1080 pixel) camera generates 2.92 GB per hour, 70 GB per day, and over 2TB per month. If you have 1,000 cameras, that's over 2PB of data.
For xProtect servers running Windows, the Tiger Bridge Connector can be used to move the video files to either IBM Spectrum Scale or IBM Cloud Object Storage.
Deep Dive into HyperSwap for Active-Active applications and Disaster Recovery
Andrew Greenfield, IBM Global Engineer for Storage, explained the different ways HyperSwap is implemented across the IBM storage portfolio.
For IBM DS8000, HyperSwap is based on Metro Mirror synchronous replication. In the event that the primary DS8000 fails, the host server can automatically re-direct all I/O to the secondary DS8000. This is often referred to as "High Availability" (HA), and in some cases can serve as Disaster Recovery.
For IBM Spectrum Virtualize products, including SAN Volume Controller (SVC), FlashSystem V9000, Storwize V7000 and V5000 products, as well as Spectrum Virtualize sold as software, the implementation is different.
Previously, SVC offered Stretched Clusters, which put one node in one site, and a second node at another site, which allows for an Active/Active configuration. Unfortunately, the nodes in FlashSystem V9000 and Storwize are "connected at the hip", effectively bolted together, so putting separate nodes in different locations was not possible. To solve this, IBM developed HyperSwap that allows one node-pair to replicate across sites to another node-pair in the same Spectrum Virtualize cluster.
However, even though it is called "HyperSwap", it is not implemented in any way similar to the DS8000 method. Instead, Spectrum Virtualize uses the Global Mirror with Change Volumes to replicate data between sites.
IBM Storage and VMware Integration
This session was co-presented by Brian Sherman, IBM Distinguished Engineer, and Steve Solewin, IBM Corporate Solutions Architect.
For nearly two decades, IBM is a "Technology Alliance Partner" with VMware. To provide consistent integration to all the features and functions of VMware, IBM Spectrum Control Base Edition (SCBE) is provided at no additional charge for IBM DS8000, XIV, FlashSystem and Spectrum Virtualize products.
SCBE is downloadable as an RPM for RedHat Enterprise Linux (RHEL) can run bare-metal or as a VM.
For those using Hyper-Scale Manager, it will automatically install a special A-line-only version of SCBE. It will install SCBE, but it will only manage the A-line products (FlashSystem A9000, FlashSystem A9000R, XIV and Spectrum Accelerate).
Storage admins can define "storage services" that can be assigned to vCenter. This allows VMware admins to allocate storage in self-service mode.
After the meetings were over, IBM had a special event at the Universal City Walk to enjoy some drinks, food, and conversation, and to watch Blue Man Group.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here's my recap of the afternoon sessions of Day 1.
Storage Brand Opening Session - Craig Nelson
Craig Nelson, Brocade manager for IBM Field Sales Channel, indicated the network equipment is the bridge that brings servers and storage together.
The squeeze -- faster servers and Flash storage causes storage networking to become the bottleneck. Fibre Channel will remain the protocol of choice for the next decade.
"Speed is the net currency of Business" -- Marc Benioff, Salesforce CEO.
Craig drew an analogy. We have been focused on making hard disk drives faster, and then Flash changed the game. Likewise, car manufacturers have focused on making gas engines better, and then Tesla Motors introduces an electric car with insane performance. The early models actually had an "Insane Mode".
The new Gen6 models of IBM b-type SAN equipment will support 32Gbps and 128Gbps ports. That's Insane!
Later models of Tesla Motors offer a "Ludicrous Mode". For flash storage, it is NVMe. NVMe can get storage down to 20 microsecond latency. That's Ludicrous!
Craig put in a plug for two Brocade sessions: "BEWARE - The four potholes on your road to success when deploying flash storage" and "Tune up your storage network! Is it healthy enough for flash storage and next-gen server platforms?"
Storage Brand Opening Session - Clod Barrera
Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist, presenting storage industry trends.
IDC predicts data capacity to grow 60-80% CAGR. This would require 44 percent drop in $/GB per year to maintain flat budget. Unfortunately, flash media cost is only dropping 25-30 percent per year, and spinning disk only 19 percent per year.
Since storage media will not offset capacity growth, we need other technologies to compensate, including compression, deduplication, defensible disposal, and "cold" storage to tape or optical media.
The smallest persistent storage that IBM has been able to achieve is 12 atoms. Current disk technology is 1200 atoms. Since 1956, IBM and the rest of the IT industry have improved storage 9 orders of magnitude, and now there are only 2 orders of magnitude left.
Clod poked fun at the "Star Wars: Rogue One" movie, indicating that their idea of the future of storage was a huge tape library. See my December 2016 blog post [Has your data gone rogue?]
What does it take to storage information forever? Tape will certainly be around. IBM Zurich demonstrated a 220TB back in 2015 as proof of technology.
A good example of the need for long-term retention are US films. Of those from the silent era, over 90 percent are lost. Over half of the films prior to 1950 are lost. The silver nitrate film stock that the reels were made of have deteriorated. Now that more movies are made digitally, can we do better?
Clouds will move from 10GbE to 25GbE. No slow down for FC in datacenters. Flash storage and object storage are both growing quickly
Move over Software-Defined Storage, Converged and Hyperconverged systems, the new up-and-coming thing are "Composable Systems deployed in Pods" adjustable hourly by workload requirements.
To protect against Ransomware, use "air gap" protection, not on the same network as production workload.
New storage models are needed for Cognitive workloads. Clod put in a plug for Joe Dain's presentation "Introducing cognitive index and search for IBM Cloud Object Storage leveraging Watson"
Storage Brand Opening Session - Axel Koester
Axel Koester, IBM Storage Chief Technologist, presented more storage industry directions.
What will the world look like in 10 years. Today mostly procedural programming, with some statistical big data, and a bit of machine learning. In 10 years, it will be mostly statistical and machine learning, with very little procedural programming. Why? Because it is faster to train computers with Machine Learning, than to program procedurally.
Examples of machine learning are IBM Watson, Google AlphaGo, drive-AI. Axel would rather be a passenger in a machine-learned self-driving car, than a procedurally-programmed one.
Neural networks to interpret hand-written numbers. Welcome to "Unsupervised learning".
A subset of Machine Learning is Deep Learning, a major breakthrough in 2006. Deep Learning is a subset of Machine Learning that uses three or more layers of neural networks. For example, face recognition "deep learning" algorithms can also be used to detect defects through visual inspection of circuit boards.
How does this impact storage?
Procedural -- archive test cases used
Statistical -- store all data for parallel processing
Machine Learning - train sample data, then archive and re-train yearly. Driving 5 minutes = 4 TB of sensor data used for self-driving cars
For Neural processing, x86 CPU are suitable for prototyping. GPU co-processors better, efficient but uncommon. IBM has developed the "TrueNorth" chip does nothing by Neural - 4096 cores with only 70 mW of energy consumption. No clock, instead dendrites, synapses, axons and neurons.
Instead of "Build or Buy?" the new question is "Train or Buy?" Train with confidential data, or buy ready-to-run 100% pre-trained cognitive systems as a service.
AI Frameworks are available on Docker containers with Kubernetes with Persistent storage (Ubiquity) such as Spectrum Scale. These frameworks include DL4J, Chainer, Caffe, torch, theano, tensorflow.
NVMe -- NVM is local only, how to do HA and DR? There are three options:
DB asynchronous shadowing
DB mirroring over NVMeOF
Cluster file system replication of persistent data, such as IBM Spectrum Scale
Example car manufacturer with 50 SAP HANA in memory instances on 4 Spectrum Scale nodes. IBM achieved 50,000 new files per second. Most NAS systems do much less.
Faster media on smaller electronics Holmium atoms on Magnesium Oxide on silver base, resulting in "single atom storage." ATM needle tip magnetizes, measured with Tunnel Magneto-resistance. Unfortunately, reading the data causes it to lose its value, so it is not as persistent as the 12-atom method described by Clod earlier.
As the title suggests, I explained why there is so much interest in Software-Defined Storage in the IT industry, what software-defined storage is, and how to deploy these solutions in your existing infrastructure without the full rip-and-replace. I covered which IBM products are available as software, pre-built systems and/or Cloud services.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Day 1 included keynote sessions. Here is my recap for the morning.
General Session "The Quantum Age"
Amy Hirst, IBM Director of Systems Training, served as emcee for the General Session. The theme this week is "Power of Knowledge, Power of Technology, Power of You. You to the IBM'th power".
Chris Schnabel, IBM Q Offering Manager, explained what "IBM Q" is.
Chris feels "our intuition of what we can compute is wrong". Classical (non-Quantum) computing has evolved over past 100 years.
Consider Molecular geometry. The best supercomputer can only handle the smallest molecules, those with 40 to 50 electrons, and even then are unable to calculate bond lengths within 10 percent accuracy. Quantum computing can.
Another area is what computer scientists call the "Traveling Salesman Problem". If you had a list of 57 cities, what would be the optimal path to minimize the distance traveled to get to all of the cities. Doing an exhaustive search would be 10 to the 76th power. Dynamic Programming techniques provide some shortcuts, reducing this down to 10 to the 20th power, but still, that is impossible on most computers.
Chris mentioned that there are easy problems to solve in polynomial time, and hard problems that are exponential, in that they get worse and worse the bigger the input set. There will always be hard problems.
"Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy."
-- Richard Feynman
Nature encodes information, but not in ones and zeros. Quantum computers are measured on the number of Qubits, their error rate, etc. The three factors that IBM focuses on are Coherence, Controllability and Connectivity.
Chris explained how Superposition and Entanglement are used in Quantum Computers. I won't bore you with the details here, but rather save this for a future post.
Today: 5 to 16 Qubits (can be simulated with today's classical computers. 5 Qubits is the power of your typical laptop)
Near future: 50-100 Qubits (too big to simulate on supercomputers), with answers that are approximate or correct only 2/3 of the time.
Future: millions of Qubits, fault-tolerant to provide exact, precise answers consistently.
Quantum Computing opens up a new range of problems, what Chris call "Quantum Easy" problems. Problems that might take years to solve on classical supercomputers could be solved in seconds on a Quantum computer.
Chris showed a picture of [Colossus], the first digital electronic computer used in the 1940s. Quantum computing today is like 1940's of classical computing.
IBM is now working on Hybrid Quantum-Classical algorithms, for example:
Quantum Chemistry - can be used in material design, healthcare pharmaceuticals
Optimization - logistics/shipping, risk analytics
There are different ways to build a quantum computer. IBM chose a single-junction transmon design, using Josephson junctions. While the chips are small, the refrigerators they are contained in are huge, and have to keep the chips at very cold 15 milliKelvin temperature (minus 459 Fahrenheit)!
To get people excited about Quantum computing, IBM created the "IBM Q Experience" [ibm.com/ibmq] that allows the public to run algorithms on a basic 5 Qubit system using a simple drag-and-drop interface to put different transformational gates in sequence.
IBM Research team were shocked to see 17 publications in prestigious journals make practical use of this 5 qubit system! Since then, IBM now offers a Software Developers Kit (SDK) called QISkit (pronounced Cheese-kit) as a text-based alternative to the drag-and-drop interface.
Amy Hirst came back on stage to remind people to use Twitter hashtag #ibmtechu to follow the event. There are two more events like this planned for the end of the year. A Power/Storage conference in New Orleans, October 16-20, and another event focused on z Systems mainframe, November 13-17.
Pendulum Swings Back -- Understanding Converged and Hyperconverged Systems
This presentation has an interesting back-story. At a client briefing, I was asked to explain the difference between "Converged" and "Hyperconverged" Systems, which I did with the analogy of a pendulum. I used the whiteboard, and then later made it into a single chart.
At the far left of the pendulum, I start with mainframe systems of the early 1950s that had internal storage. As the pendulum swings to the middle, I discuss the added benefits of external storage, from RAID protection and Cache memory to centralized management and backup.
To the far right of the pendulum, it swings over to networked storage, from NAS to SAN attached devices for flash, disk and tape. This offers excellent advantages, including greater host connectivity, and greater distances supported to help with things like disaster recovery.
Here is where the pendulum swings back. IBM introduced the AS/400 a long while ago, and more recently IBM PureSystems that combined servers, storage and switches into a single rack configuration. Other vendors had similar offerings, such as VCE Vblock, Flexpod from NetApp and Cisco, and Oracle Exadata.
Lately, the pendulum has swung fully back to internal storage, with storage-rich servers running specialized software on commodity servers. There are two kinds:
Pre-built systems like Nutanix, Simplivity or EVO:Rail which are x86 based server systems, pre-installed with software and internal flash and disk storage.
Software that can be deployed on your own choice of hardware, such as IBM Spectrum Accelerate, IBM Spectrum Scale FPO, or VMware VSAN.
So, over time, my single slide has evolved, and fleshed out into a full blown hour-long presentation!
Cloud storage comes in four flavors: persistent, ephemeral, hosted, and reference. The first two I refer to as "Storage for the Computer Cloud" and the latter two I refer to as "Storage as the Storage Cloud".
I also explained the differences between block, file and object access, and why different Cloud storage types use different access methods.
Finally, I covered some of our new public cloud storage offerings, using OpenStack Swift and Amazon S3 protocols to access objects off premises, including the new Cold Vault and Flex pricing on IBM Cloud Object Storage System in IBM Bluemix Cloud.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Thursday evening, we had the "Meet The Experts" sessions. There were four: Storage, Power Systems, z/OS, and a fourth one focused on z/VM and Linux on z Systems. I was on the expert panel for Storage.
Mo McCullough was the emcee. Special thanks for Shelly Howrigon in her help with this event.
(Disclaimer: Do not shoot the messenger! We had a dozen or so experts on the panel, representing System Storage hardware, software and services. I took notes, trying to capture the essence of the questions, and the answers given by the various IBM experts. The answers from individual IBMers may not reflect the official position of IBM management. I leave out any references to unannounced plans or products. Where appropriate, my own commentary will be in italics.)
When will IBM offer a single pane of glass management for all of its IBM storage products?
IBM is working hard on this. Our strategy is to focus on IBM Spectrum Control as the primary answer. We have extended support across block, file and object, with support for IBM Spectrum Scale and IBM Cloud Object Storage System. We have also provided plug-ins for VMware, Cisco UCS Director, and OpenStack Horizon, for those who prefer those management systems instead.
What we really need are REST APIs!
Good point. IBM already has some REST APIs for the DS8000, XIV and Spectrum Protect, now that IBM has browser-based GUI across its entire product line, it is our strategy to offer REST API across our product line as well.
What is the next generation of ProtecTIER Data Deduplication going to look like?
IBM is focused on provided "data deduplication" for backup workloads directly through IBM Spectrum Protect backup software. IBM continues to sell IBM ProtecTIER.
(Virtual Tape Libraries like IBM ProtecTIER and Dell EMC Data Domain were created to handle the fact that many backup software back only were designed for tape drives and libraries. VTL was disk that pretended to be tape library. Now that IBM Spectrum Protect, NetBackup, Commvault, and all of the other modern backup products write natively to disk, object storage or Cloud services, there really isn't a need for VTL products any more.)
Why does IBM bother with all-Flash version of DS8000 when it already has IBM FlashSystem?
Different products for different workloads. IBM DS8000 offers unique support for z System mainframe FICON attachment and 520-byte block support for IBM i. IBM also offers all-Flash Elastic Storage Server, all-Flash SVC and Storwize products, that complement the IBM FlashSystem product line.
We like how XIV can hot-enable encryption, even with existing data on it. Why doesn't DS8000 offer this?
Two separate implementations. At the time IBM DS8000 encryption was designed, it was decided that the client needed to enable encryption before writing any data.
Will we see a spinning disk version of the FlashSystem A9000
Flash is now less expensive than spinning disk, I don't see why IBM would go backwards. The future is Flash.
We would like Spectrum Control to manage our Dell EMC Isilon
Yes, we have heard that from others. We are working on extending our third party support. Send in your cards and letters to help us prioritize. Or, better yet, submit a "Request For Enhancement" (RFE).
The difference between Tier 0 (Write Endurance) flash and Tier 1 (Read Intensive) flash is confusing, are there any plans in the IT industry to simplify this?
No, if anything it will get worse. Today, IBM's Tier 0 is 10 Drive Write Per Day (DWPD), and Tier 1 is 1 DWPD. Other SSD drives offer 2, 3, 5, 10, 15 and 25 DWPD. As people buy more Flash, and less disk, expect more differentiation in this area.
We would like to tune Easy Tier on the Storwize products
Understood. IBM typically implements new features on the DS8000 platform first, then rolls them over to Spectrum Virtualize. The ability to influence allocation order, pin or avoid tiers, and have application API to influence the placement are already in DS8000.
What will the future of Storwize look like?
We don't have enough time to cover that in this meeting.
Recently, you raised the maximum Storwize FlashCopy background copy rate from 64 MB/sec to 2 GB/sec, but is that realistic?
The setting provides the background task a target "grains per second" to try to achieve. It may not be possible depending on your configuration and the number of concurrent tasks. Your Storwize may be so busy with background activity that it won't take host I/O.
We have been giving you our wishlist, but are there any questions the IBM experts have for the audience
Yes, are there any clients being asked to secure storage against Ransomware and insider threats from disgruntled employees?
(Several hands went up, and we collected their names to have further discussions.)
How should we assign business value to data?
IBM Spectrum Virtualize allows you to assign metadata tags to files, so that these can be used to drive different policies.
(The process of assigning business value is often called "Data Rationalization" and is part of ILM, BC/DR, and Data Governance efforts.)
I am concerned that AES 256 encryption is not good enough now that there is Quantum Computing.
It will be decades before Quantum Computing will be good enough to break these codes.
Will Blockchain drive huge or unique storage requirements?
No. The entries are small. You are appending small transactions to the end of existing ledgers. Nothing unique or different.
Were there any topics not adequately covered at this conference?
IBM didn't have much to offer for Spectrum Compute family of software, the Software Defined Infrastructure (SDI) that runs on both x86 and POWER systems. This should be done under the POWER brand, but many clients use Spectrum Compute with x86 servers. Ironically, Spectrum Compute products are managed under the Storage division, since Spectrum Compute and Spectrum Storage work well together.
We would like Storwize's clever NPIV to be implemented in all of the other IBM arrays, starting with DS8000.
That probably won't happen, as they are different architectures. Whereas Storwize and the rest of IBM Spectrum Virtualize family were designed for nodes to fail, and take their ports down with them, the DS8000 has independent I/O bays that continue to run independent of either POWER8 node. Likewise, FlashSystem 900 has similar separation between the FCP adapters and the processing nodes.
Can we have consistent licensing across the entire IBM Spectrum Virtualize set of products, please?
We have a task force to investigate this, and will gladly add your name to the list for input and feedback.
While the conference continues Friday morning, for many attendees, this was the last event.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here is my recap of the sessions on the morning of Day 5, the last day of the conference.
Integrating IBM Storage in Container Environments
Dr. Robert Haas, IBM CTO Storage for Europe, presented IBM Storage for Docker containers. These are different from containers in IBM Cloud Object Storage, and different from the Container Pools used in Spectrum Protect.
Robert gave an overview of IBM Spectrum Conductor, part of the IBM Software Defined Infrastructure (SDI) Spectrum Compute family of software products. The goal is to analyze large amounts of data, access these data efficiently, and protect the data, results and insights as intellectual property.
IBM Spectrum Compute comes in several offerings. IBM Spectrum LSF (Load Sharing Facility) manages long-running batch jobs for modeling, design and simulations. IBM Spectrum Symphony provides low-latency for risk analytics in the financial services sector. IBM Spectrum Conductor comes in two flavors. Conductor for Spark (CFS) manages Spark analytics. Conductor for Containers (CFC) handles Docker and Kubernetes containers.
Docker is the run-time platform. While there are other container run-time platforms like RKT and LXD, Docker is clearly the marketshare leader, growing 40 percent per year.
Statistics from the latest DockerCon2016 conference showed the most popular use cases and workloads for Docker. What can run in Docker: Lots of applications can be "containerized", including Redis, MongoDB, PostgreSQL, OracleDB, Java, to name a few. Docker is well established in enterprises, including service providers, healthcare, insurance and financial services, public sector, and technology firms.
Kubernetes, Mesos and Docker/Swarm are a layer above, as orchestrators. Spectrum Conductor for Containers uses Kubernetes and other open source tools to coordinate activity. Orchestrators restart failed applications, and can scale up or scale down the number of instances as needed. Orchestrators can manage groups of applications, across clusters on-premises and off-premises Cloud.
From a storage perspective, containers access storage like bare-metal operating systems, bypassing all of the layers normally associated with bloated Virtual Machine hypervisors. It also eliminates single root I/O virtualization (SR-IOV) that VMs use to compensate.
Persistent storage can be isolated, so that containers cannot see the files of other containers. This provides multi-tenancy.
Internal persistent storage (directory on host file system). However, if you move a container from one host to another, you may lose access to this internal storage.
External volume, manually mounted.
Volume driver plug-in REST API that automatically mounts it.
The fourth method is preferred. Plug-ins are available for IBM Spectrum Scale, GlusterFS, Portworx, Rancher Convoy, RexRay, and Contiv. The start-up Flocker have gone out of business last year.
The Docker hosts can attach to IBM Spectrum Scale in all of its supported offerings, including POSIX, NFS and SMB protocol. Containerized applications can move from one Docker host to another, and continue access the IBM Spectrum Scale namespace.
IBM has created the "Ubiquity Volume Service" that provides a consistent API for Docker and Kubernetes. This will use IBM Spectrum Control Base Edition to support IBM Spectrum Scale, Spectrum Accelerate, Spectrum Virtualize and DS8000 storage systems. For IBM Spectrum Scale, volumes are mapped to iSCSI volumes, filesets or directories. For other devices, volumes are mapped to block LUNs. Ubiquity is publicly available on GitHub.
Enterprise Applications for IBM Cloud Object Storage
Andy Kutner, IBM Cloud Architect, presented the various options available for NAS gateways that can front IBM Cloud Object Storage.
Ctera offers NAS gateways, and Endpoint agents for backup and Enterprise File Sync & Share (EFSS). This vendor targets Remote Office/Branch Office (ROBO) and small NAS consolidation that have less than 60 TB per office IBM is a reseller of Ctera, so you can get both Ctera and IBM COS from the same IBM sales rep.
Nasuni offers a global file system, accessible from any device, smartphone, tablet or desktop. They are focused on taking out EMC and NetApp NAS solutions. Performance at the edge, combined with capacity in the client's chosen Cloud (including IBM Cloud Object Storage or IBM Bluemix). Infinite snapshots replace backups, offering RPO of 1 minute for Disaster Recovery. Their global file system "UniFS" offers file locking.
Panzura focuses on Cloud Integrated NAS, File Distribution, and Collaboration. This can help eliminate "islands of storage". The File Distribution can be any type of file, but was originally designed for Media and Entertainment, such as videos. Collaboration employs EFSS features for workgroup shared file folders, such as CAD/CAM or engineering blueprints.
IBM Spectrum Scale can provide NFS and SMB access to files, and then move colder, less active data to IBM Cloud Object Storage, using Transparent Cloud Tiering feature. Spectrum Scale offers WAN caching across locations.
IBM COS now offers a native NFS v3 interface. This allows read/write NFS access, with S3 API read of the same content. Each file is mapped to a single object.
This is targeted for large scale archive, static-and-stable data, NFS-based backup software, and applications going through the transition from file-based to object-based. This is not intended for multi-site collaboration or primary NAS replacement. Regardless of the number of geographically dispersed IBM COS sites, the NAS can run on only one or two sites initially.
To provide NFS v3 support, IBM introduces new F5100 File Accessers, which talk to an IBM COS Accesser, which in turn acts on specific Vaults in the storage pools. The file-to-object mapping metadata is replicated on-premises across three File Accessers, and optionally replicated asynchronously to a second site for High Availability. S3 API can read access the file by file name, or by Object URI.
Initially, the "File Accesser" is only available as pre-built system, not as software-only.
There was not enough time to cover other solutions, including Avere, NetApp AltaVault, or Open Source S3FS.
This was a great event, just the right size, between 1,500 and 2,000 attendees. Similar IBM Technical University events coming up later this year:
(FCC Disclosure: I work for IBM. I have no financial interest in SUSE, Scality, or any other storage vendor mentioned in this post. This blog post can be considered a "paid celebrity endorsement" for IBM Storwize, IBM Cloud Object Storage, and IBM Spectrum Storage software mentioned below.)
The study takes a realistic request for 250 TB of storage, at 25 percent compound annual growth rate (CAGR), to store infrequently accessed data in an online archive, and then looks at the Total Cost of Ownership (TCO) over five year period.
The study compares five different Software-Defined Solutions and three pre-built systems. The Software-defined solutions come as software-only, requiring that you purchase the hardware separately and build it yourself. The three pre-built systems were chosen from the top three storage vendors in the marketplace: Dell EMC, IBM and NetApp.
The cost of support is factored in, as it should be. To keep things equal, no data reduction like data deduplication or compression were used.
In an odd approach, the study mixes block, file and object based approaches all in the same study.
You can read the full 14-page study (linked above). I have organized the results into a single table, ranked from best to worst, color coded for the best deals in green ($100K to $200K), moderate solutions in yellow ($200K to $300K) and most expensive in red (over $300K). I put the software-only options on the left and pre-built systems on the right.
SUSE Enterprise Storage 4
IBM Storwize V5010
DataCore SAN Symphony
Red Hat Ceph Storage
Dell EMC Unity 300
I am often asked, "Isn't the software-only, build-it-yourself approach, always the lowest cost option?" Now, I can answer, "Sometimes yes, sometimes no." Fortunately, IBM offers Software-Defined Storage in a variety of packaging options including software-only, pre-built systems, and in the Cloud as a service.
IBM Storwize V5010 is based on IBM Spectrum Virtualize software, which you can deploy as software-only on your own x86 servers. This was not mentioned in the study, and perhaps it is my job to remind people that this option is also available for those who want to build their own storage.
For that matter, IBM Cloud Object Storage System -- available as software-only, pre-built systems, and in the Cloud -- might also be a cost-effective alternative.
Next week I will be in Orlando, Florida for the IBM Systems Technical University. If you are attending, stop by one of my presentations, or look for me at the Solution Center at one of the IBM peds, or attend the "Meet the Experts for IBM Storage" on Thursday!
This week, I was part of an all-day event called "Healthcare and Research Trends & Directions in a Cognitive World" at the IBM Executive Briefing Center (EBC) in Rochester, MN. I was one of many presenters covering Information Technology to improve healthcare outcomes. Todd Stacy, IBM Director Server Sales for US Public Market, served as our emcee.
This was a great day. Special thanks to Kathy Lehr, Trish Froeschle, and Scott Gass for organizing this event! We had clients from a variety of Health Care and Life Science industry backgrounds. I certainly learned a few things myself.
Dr. Michael Weiner, IBM Chief Medical Information Officer, Watson Health, covered some of the real challenges not just facing the United States, but also other countries. On average, healthcare in USA [costs over $10,000 USD per American citizen]! Compare that to only $3,700 USD for the folks in the United Kingdom! In fact, nearly all industrial nations spend between $2,000 and $5,000 per person. Where does all the U.S. money go?
A big challenge is our ever-aging population. Every day, there are 10,000 [Baby Boomers] reaching their 65th birthday, with fewer people in the 25-44 age group to work as nurses to take care of them. About 15 percent of the US population are elderly (over age 65) and this is expected to grow to 20 percent in year 2040. The situation is even worse in Japan, where 25 percent of the population today is elderly, and this is expected to be 40 percent by year 2060.
New Care Models
In some countries, like Australia and Japan, post office workers who spent their time delivering mail, now can stop in to check in on elderly people. As people ship less mail, using social media or email instead, this keeps the postal workers employed, in a manner that provides society value.
The USA enjoys one of the lowest costs for food, but then suffers from an epidemic of obesity, with over 34 percent of Americans are obese. When New York City eliminated Trans Fats, heart attacks dropped considerably.
In 2009, the Health Information Technology for Economic and Clinical Health [HITECH] Act required the digitization of medical information, known as "Meaningful Use", which has greatly influenced healthcare facilities. This was implemented by a combination of incentives and penalties. Now, more than than 92 percent of hospitals in the USA have digitized medical information! The rest are still using paper and Xray film images. Some places were initially exempted, such as Assisted Living Homes for example, so there is still more work to be done.
An advantage of using computer-based solutions like Artificial Intelligence is that it eliminates bias. When a woman walks into an Emergency Room complaining about chest pains, few health staff would consider this a sign of heart attack. When a man does same, health staff considers heart attack as the first diagnosis, at the risk of missing out on other possibilities.
Every year, over a million articles related to healthcare research are published. Who can read all this in a timely manner? IBM Watson! After [winning in Jeopardy], IBM Watson was "sent to medical school" to learn how to assist doctors in diagnosing patients.
Transforming Health Care Data Management with IBM Spectrum Storage
Greg Tevis, IBM Software Defined Storage Architect, and Raj Tandon, IBM Senior Strategist, co-presented this introduction to IBM Spectrum Storage family of products. They covered examples with IBM Spectrum Virtualize, IBM Spectrum Control, IBM Spectrum Protect, IBM Spectrum Scale, IBM Cloud Object Storage, and IBM Copy Data Management. The latter having support directly for EPIC and Cache databases.
Cognitive Imaging Solutions for Healthcare Providers
Jason Crites, IBM Healthcare and Life Sciences Data Solutions Leader, and Wayland Vacek, Enterprise Sales Manager for Merge, presented IBM Watson Imaging Clinical Review, from IBM's acquisition of the Merge company. The solution is based on IBM Spectrum Scale as the back-end storage repository.
Merge has been around for more than 20 years, with clinical workflow offerings in Cardiology, Radiology, Orthopedics and Eye care. Often, IBM Watson is able to identify things in medical images that escape the review or radiologists or other medical specialists.
At HIMSS conference earlier this year, The human radiologists were shown a collection of images used to train IBM Watson. The human radiologists only identified 20 percent of the images correctly, while IBM Watson got all of them, every time. In many cases, human radiologists have only a few seconds to look at an Xray image. Computers like IBM Watson are now fast enough to compete directly with human radiologists in the same number of seconds.
Building a Foundation for the Cognitive Era in Healthcare and Life Sciences
Dr. Jane Yu, IBM Systems Architect, Healthcare & Life Sciences, and Dr. Frank Lee, IBM Global Sales Leader, IBM Software Defined Infrastructure & Life Sciences, co-presented this topic. They present five challenges:
Growing data volumes are making it more difficult to manage, process and store this data.
Scientists find themselves spending more than 80 percent of their time manually integrating data from silos, and less than 20 percent of their time doing actual research and deriving insights from their analyses.
Compute- and data-intensive workflows may take days to complete on existing server and storage systems.
IT organizations must keep up with rapidly evolving applications, development frameworks, and databases for preferred. Health care Life Science (HCLS) applications. This includes SAS, Matlab, Hadoop, Spark, NoSQL databases, as well as Deep Learning and Machine Learning workloads.
Scientific integrity and government mandates increasingly require collaboration across organizational boundaries.
In one example, Sidra Medical and Research Center plans to map the genomes of all 250,000 citizens in the Middle Eastern country of Qatar. Imagine that processing each Qatari citizen will generate 200 GB of data for this project, resulting in 50 Petabytes (PB) of data!
Combining IBM Spectrum Compute products with IBM Spectrum Scale storage, can help address these challenges.
Modernize & Transform Helathcare with IBM Storage Solutions
Finally, I presented a 90-minute breakout session that covered three solution areas:
Flash storage to speed up medical records and research. Those who have already implemented Electronic Health Records (EHR) for "Meaningful Use" compliance recognize the value this provides to improving healthcare. Adding All-Flash Arrays such as IBM FlashSystem, Storwize V7000F or DS8000F can drastically improve application performance.
Spectrum Scale and IBM Cloud Object Storage for Vendor Neutral Archive. It seems silly that each PACS vendor has its own little island of storage. A better approach is to send all PACS data from various vendors into a "Vendor-Neutral" storage repository. Both IBM Spectrum Scale and IBM Cloud Object Storage System, either linked together or used separately, can be part of a VNA solution.
VersaStack to simplify deployments. VersaStack is a Converged System that combines best-of-breed Cisco servers and switches with best-of-breed IBM storage, pre-cabled, pre-configured, and pre-loaded with all the necessary software to manage the environment as a single entity. This can reduce the time it takes to deploy new medical applications from weeks to just hours.
The new TS1155 enterprise tape drive can write up to 15 TB uncompressed data to existing JD/JZ/JL media.
It can read/write existing 10TB-formatted JD media, and 7TB-formatted JC media, written by former TS1150 drives. It also can offer read-only support for older 4TB-formatted JC media from TS1140 drives.
These are uncompressed capacities, and some clients achieve 2x or 3x compression on top of these capacities. This depends heavily on the type of data. Your mileage may vary, as they say.
Most of the rest of the features of the TS1150 drives carry forward., The performance 360 MB/sec is similar, encryption via IBM Security Key Lifecycle Manager (SKLM) is similar, and support for IBM Spectrum Archive via Linear Tape File System (LTFS) format is similar.
An interesting development is that the TS1155, in addition to standard 8Gb Fibre Channel attach, is the first IBM enterprise drive to also offer 10Gb Ethernet support. IBM will offer both RDMA over Converged Ethernet (RoCE) as well as iSCSI support.
The newest member of the IBM Spectrum Storage software family, IBM Spectrum Copy Data Management automates the creation of snapshot images (FlashCopy for those familiar with IBM terminology) on IBM, NetApp and EMC storage arrays. These copies can be made for various uses, such as DevOps, Dev/Test, Backup/Restore, and Disaster Recovery.
At some data centers, these copies can consume as much as 60 percent of your total storage space, because often each developer and tester are generating their own copies. Instead, having copies automated, registered, cataloged, and made available to developers and testers eliminates rogue copies.
This release adds support for additional databases, including Microsoft SQL Server on physical machines, SAP HANA in-memory databases, and Epic/Caché from InterSystems used in Electronic Health Records (EHR) management systems.
IBM also adds support for long-distance Vmotion for VMware virtual machine images. The target for this movement is IBM Spectrum Accelerate running on IBM Bluemix Cloud, supporting Hybrid Cloud configurations.
Last month, I presented at the "IBM Technical University" event in beautiful Atibaia, Brazil. Here is my recap of the event.
Marcelo Porto, IBM General Manager for Brazil and Client Unit Executive for Retail
What a great way to start a conference! Marcelo asked if everyone was comfortable? Everyone cheered in the affirmative.
He then said "Well, not for long. We will take you out of your comfort zone! You will disrupt yourself, and disrupt your companies. You will learn about new technologies and solutions that will make you very uncomfortable."
He explained how everything is virtual, specifically the three companies Airbnb, Waze, Uber. All of these three have new transformational business models, and he suggested all companies should follow suit.
He then said people need to be focused on four things:
Adopting an "agile attitude"
Act like you own the company
Don't cling to the past
Have the courage to re-invent yourself and your company
Frank Koja, IBM Vice President for Sales, Enterprise Systems Hardware
(Managers and business leaders could probably raise this percentage considerably if they talked to their employees before making decisions, but that's another blog post!)
Frank showed a video of an IBM client, Plenty of Fish (POF). This is a worldwide dating site with three million POF members in Brazil. They now process over 30,000 requests and/or messages per minute. FlashSystem connected to 30 servers makes that possible.
OpenPower consortium started with just 5 companies in 2014 for technology collaboration. Today, 250 members across 26 countries in six continents collaborate to make POWER technology as ubiquitous a commodity as Intel x86.
Frank then switched to "Business models" innovation. Out of the audience of about 800 people, only 10 raised their hands that have heard of Blockchain (he asked IBMers not to raise their hands, as all IBMers have heard of Blockchain!).
Frank feels that Blockchain is the most disruptive innovation since Internet banking. Blockchain affects supply chain, finance, insurance, shipping logistics, customs inspections, and government registrations.
A video showed a woman from Everledger, which uses Blockchain for shipping diamonds. IBM offers Blockchain on LinuxOne mainframe servers.
Hybrid Cloud is point of no return, including Local, Dedicated and Public clouds. Frank feels we need to cloudify all business processes.
Mauro Angelo, IBM Enterprise Strategy & Industry Solutions Director
Mauro explained that ideas are turned into inventions, and inventions are put to good use to bring forth innovations.
If your business is not cognitive you are a full era behind. Machine learning is not knew. IBM DeepBlue beat Grandmaster in Chess tournament back in 1997.
Mauro then focused on eight specific trends:
Systems of Engagement (SoE)
This is the combination of Mobile applications and Social business. IBM invited the first smartphone, the Simon, back in 1994. Apple's iPhone came later in 2007. Pokemon Go is example of augmented reality.
Cloud offers new service and location models. IBM [SoftLayer], [Bluemix], and [Kenexa] are a few examples.
There have been a lot of enhancements in this space, including Natural Language Processing (NLP), visual recognition, even smell recognition. Cognitive solutions can also identify the appropriate context, such as GPS location. And Cognitive solutions can interact with users to ask for clarifications. It can process "Big Data", the collection of non-structured data that normal Relational Database Management Systems (RDBMS) do not touch. Finally, they can learn, something often referred to as "Machine Learning".
In 2011, IBM Watson beat two humans at the TV show game Jeopardy! Today, [Dino, a toy from CogniToys] provides Watson-like capabilities to children.
Mauro got one for his daughter. She naturally interacts with toy. "How much does an elephant weigh?" she asks. "It depends on the elephant, but a fully grown elephant weighs more than 2,000 kilos" it responds. That's cool.
Wearables like Fitbit can track blood pressure, minutes of exercise, total steps walked. IBM helped Under Armour company develop an app in this space.
Eliminates middlemen or trusted third party (TTP). The hotel chain, Hilton, is testing out a robot called Pepper, which can use Blockchain to book tennis courts.
These are technologies thinner than a strand of hair, measured in nanometers. The focus is to develop stronger, lighter materials, and macromolecules for life sciences for medicine delivery.
Mass customization meets personalization and fast design prototypes. This is not just limited to plastic, but also metal, paper, wood, biomaterials, ceramics, food, and even cement.
Cement? That's right. A Chinese company prints houses using a cement 3D printer. In a country of over one billion people, this company has figured out how to build houses without human laborers.
Internet of Things (IoT)
Olli, a 12-person self-driving bus, is the brainchild of Local Motors. They are testing it out in National Harbor, and hope to roll it out to cities like Copenhagen, Miami, and Las Vegas.
Luis Liguori, IBM Distinguished Engineer and CTO for IBM Brazil
What does IBM mean by "Digital transformation?" What separates success from failure? Developed countries from less developed countries?
Is it culture? Whether people focus on the long term, or just the short term? Does the culture encourage you to foresee the future, and adapt accordingly? Does the culture encourage you to be brave and bold? Do you hide behind Business case return on investments (ROI)? Does your culture consider conflict to be good or bad? The answer: Good!
Does your company have a purpose? When humans no longer serve purpose, they die. The same is true for companies. He said the secret to success is the four "R's" -- Relevant, Resources, Reputation and Rigor.
For example, in 1996, the Kodak was ranked the 4th largest, it filed bankruptcy in 2012 because it was no longer relevant.
Consider Samsung. Samsung has lost its reputation with the latest "Samsung Galaxy Note7" fiasco of exploding batteries!
Airbnb is an example of Digital Transformation. Who knew that there were lots of people who wanted to rent out their bedrooms and bathrooms to strangers!
Luis feels that successful companies are either born digital, or transforming to digital. Industries are merging. Lines are blurring between industries. The latest acquisition between AT&T and Time Warner is an example.
Cognitive brings intelligence to decision making. For example, Watson health has been put to task to focus on Leukemia. In one case, Watson was able to [pinpoint a rare form of Leukemia] that had misdiagnosed and being treated incorrectly with little effect.
Why cognitive? Because human beings cannot read or remember as well as computers. There are thousands of peer-reviewed articles published every day. People are afraid to act to avoid mistakes. Computers are fearless.
Did you know that Brazil celebrates "Black Friday"? There is no "Thanksgiving" in Brazil, but retailers liked the idea of having people stand outside in the middle of the night to start their Christmas shopping! A few years ago, there were [a few problems], but in most recent years, it has shown to help [boost retail sales.] Based on these initial purchases, Watson can be used to help drive the rest of the Christmas retail season.
Watson can analyze personality based on social media writings. The world will be taken over by digital natives. The last century was focused inward, or "ego-centric", but in this 21st century, we will be focused outward, towards a complete "ecosystem".
Who are your competitors? Are they the companies that make products and services similar to yours? No! They are the companies that are competing for your customer's time and attention.
While I speak English and Spanish fluently, my Brazilian Portuguese is terribly rusty. We had several rooms with a pair of real-time translators. I presented the following:
Software Defined Storage -- Why? What? How?
The Pendulum Swings Back -- Understanding Converged and Hyperconverged Environments
IBM Spectrum Scale for File and Object Storage
IBM Storage integration with OpenStack
Introduction to IBM Cloud Object Storage System and its Applications (powered by Cleversafe)
IBM's Cloud Storage Options
All of my sessions were well received, and well attended!

On Wednesday night, we had a nice pool-side reception. Beers, Caiparinhas, and Caiparoskies. Caiparinhas combine a sugarcane juice-based distilled alcohol called cachaça with muddled limes and added sugar. Caiparoskies combined vodka with muddled kiwi fruit.
(Many of the IBMers from United States skipped this event to get dinner early, so they could then come back in time to watch the third and final US Presidential Debate. Because of the time zone changes, this didn't start til 11:00pm, so they could have easily attended the event and had dinner, with plenty of time to spare!)
There was also a live band! This three part band had two guitarists and one lead singer. The lead singer also did maracas and drums while singing. They covered both English and Portuguese language songs.
Rodrigo Giaffredo, IBM Engagement Catalyst
Rodrigo gave the closing session. Wearing jeans and sneakers, he reminded me of the casual storytelling style of Jeff Jonas. He organized his stories around four points:
Consider the battle between Twitter vs. Pownce in 2007. Twitter won because it offered better ways to limit what you read, or who you communicate to, through methods like Hashtags, groups, etc.
Henry Ford disrupted transportation. He realized that Time and space is money. However, as he famously said "If I asked people what they wanted, they would have said faster horses!"
Today the challenge is processing data faster. The company that is able to process faster has economic advantage.
Strong ideas focus on user needs. Weak ideas are tactical and features. Consider the [Hippo Roller]. For centuries, African women and children carried water from far away wells either on their hands on or their heads. Much of it would fall out during the long walks. The Hippo Roller holds 90 liters (about 24 gallons) and rolls easily over rough terrain.
Rodrigo showed an graph. On the y-axis was "Importance" and the x-axis "Feasibility". Solutions in the upper right corner are obvious choices. Solutions in the upper left, important but not very feasible, are considered "big bets". Solutions in the lower right, feasible but not very important, he labeled "amenities".
Most designers, architects and developers know that the later the error is found, the more expensive it is to fix. A prototype is worth a thousand meetings.
Take the company Zappos, which sells shoes online over the Internet. The founder, Nick Swinmurn, tried to get investors, getting a typical response: "What are you drinking?" (In USA, we would ask what are you smoking, but this is the way the Brazilians say it.)
With no investors, Nick built a simple website, took pictures of shoes, and fulfilled orders by purchasing the shoes from local San Francisco retailers and shipping them to the clients.
Nick started this in 1999, and finally got some $20 Million USD in funding in 2004. His simple prototype allowed him to focus on post sales support. Zappos was recognized as having the best call center, moving his operations to Las vegas, NV.
Consider the challenges of urban mobility.
Both methods eventually result in a car, but the agile prototypes allow for more effective experimental milestones.
As for Zappos, its prototype proved successful. Amazon acquired them for $1.2 Billion USD in 2009.
It is that simple: Understand, explore, prototype, and evaluate. IBM has adopted "Design Thinking" across its development organizations to better meet the needs of the marketplace.
Overall, it was a delightful event. It is nearly summer down in the Southern hemisphere, so a bit warm and humid. The attendees were all looking forward to a turn-around in the Brazilian economy, and the business opportunities that brings.
This week, IBM sponsored a nice multi-client event in San Juan, Puerto Rico. I was quite impressed with the quality of this video. Our marketing department has really done a good job on this!
This event was not just multi-client, but also spanned different industry sectors. IBM recently has realigned to five different sectors, and we had clients from different sectors attending the event.
The night before, I was able to meet most of the other IBM executives who came down for the event. Unfortunately, two were delayed because of the snow storms in the Northeast part of the United States, but they were able to arrive the next day.
The venue was the El Touro restaurant, near the Hilton Caribe. The weather was just right, about 75 degrees and breezy. It was a little humid for me, but everyone else were just happy to be out of the cold. Meanwhile it is nearly 90 degrees in Tucson, Arizona where I am from.
This was billed as a "Lunch and Learn" and the food was delicious! In an effort to keep it simple, we had small dishes of fish with fruit-based cream sauce, paella with rabbit meat and rice, pork belly, Crema Catalana and a churo for dessert. This gave everyone a sample taste of everything, without having to order off a menu.
We basically took the same approach with the presentation. First, Marcos Obermaeir and Marcos Otero, the two leads for this event, thanked the audience and explained their new roles. Marcos Obermaeir is focused on Financial and Insurance sector, while Marcos Otero focused on Communications sector.
Next we had Debbie Niven and Roopam Master, both IBM Executives, explain their roles, and how IBM can help both clients and Business Partners in Puerto Rico.
I presented samples of much larger presentations on three topics. First, the excitement over Software Defined Storage with IBM Spectrum Storage family of products. Second, IBM Spectrum Scale as a better replacement for Hadoop File System (HDFS) for Hadoop, IBM BigInsights and Hortonworks analytics deployments. Third, IBM Cloud Object Storage, and how this can be combined with IBM Spectrum Protect to backup your data to object storage either on premises, or in the Cloud.
I could have easily spoken an hour on each topic, but instead, we shortened to about 20 minutes each, in keeping with the "Tapas" theme of the restaurant. This allowed those clients who wanted to hear more to have a reason to request a follow-up visit or call.
After the clients left, the IBM team had a reception for the IBM Business Partners. About 80 percent of IBM's storage business in Puerto Rico is done through IBM Business Partners, so they are an important link in IBM's "Go-to-Market" strategy.
The moon was nearly full, and the breeze and waves were a spectacular backdrop to the conversations I had with each person I met.
This week, IBM InterConnect conference is going on in Las Vegas, Nevada.
One time in Las Vegas, I took the gondola ride at the Venetian Hotel. These are not boats with a motor on a chain or track, a but actually steered and propelled independently by the gondolier. At various points on our path, our gondolier would serenade our group with beautiful Italian songs.
As the ride was ending, I asked our gondolier how long their training program was to do this job. He told me "six weeks". I said "Wow, I would love to learn how to sing Italian songs like that in six weeks". He corrected me, "No, silly, they only hire experienced singers, and teach them six weeks to manage the gondola by turning the oar in the water."
(FCC Disclosure: I work for IBM. I have no financial interest in the Venetian Hotel, CBS Studios, or the producers of any television shows mentioned in this post. David Spark has provided me a complimentary copy of his book. This blog post can be considered an "unpaid celebrity endorsement" for the book reviewed below.)
InterConnect 2017 includes "Concourse", a trade show floor with people showing off the latest technologies. In the past 25 years, I have attended many conferences, and on occasion I have worked "booth duty". I am not in Las Vegas this week, so this post is advice to those that are.
One time, when the coordinators for an upcoming conference announced at an all-hands meeting they were looking for "a number of knowledgeable and outgoing volunteers" to work the IBM booth, one of the employees in the audience asked "How many of each?" While this might have meant to draw laughs, it underscored a real problem.
In many IT and engineering fields, the terms "knowledgeable" and "outgoing" are seen as mutually exclusive. People are either one or the other. A study titled [Personality types in software engineering], by Luiz Fernando Capretz of The University of Western Ontario, analyzed Myers-Briggs Type Indicator of personality and found the majority of engineers were "Introverts".
This line of thinking is further reinforced by the various characters on the television shows like "The Big Bang Theory". If you are familiar with the show, you have Sheldon and Amy are the most knowledgeable, but also the most socially awkward, and then you have Penny and Howard, less knowledgeable but at the more outgoing end of the spectrum.
I understand that for many engineers, working a booth at a trade show is far outside their "comfort zone". But what do you think is more likely, that you can train an engineer to work a booth in six weeks, be more outgoing, hold the right conversations, tell the right stories -- or -- train a professional model, a young, good looking man or woman, who is already outgoing and friendly, to answer technical engineering questions about your products and services?
I have been attending conferences for over 25 years, and occasionally have worked a booth or two. I started out as an engineer, but went through extensive training for public speaking, talking to the media and press, and moderating Q&A Expert panels.
Sadly, most people who work the booth get little to no training at all. You might be told your scheduled hours, how to scan bar codes on badges, and where the brochures and swag are stored. Then, you get your official "shirt" and told to wear it with a certain color pants, so that everyone looks like part of the team.
Fortunately, fellow blogger David Spark, of Spark Media Solutions, has written a book titled "Three feet from Seven Figures" with loads of advice on how to work a booth with one-on-one engagement techniques to qualify more leads at trade shows.
The title of his book warrants a bit of explanation. When you are working a booth, potential buyers and influencers are walking by, often just three feet away from you, and these could represent million-dollar opportunities.
Too often, the folks working a booth take a passive approach. They look down at their phones, chat with their colleagues, and basically wait for complete strangers to ask them a question or request a demo. This non-verbal communication can really be a turn-off. David explains this in all-too-familiar detail and how to be more actively engaged.
David shows how to break the ice and build rapport with each attendee, how to qualify them as legitimate leads, and how to handle each type of situation.
For qualified leads, you need to maximize the opportunity. If you imagine how much a company spends to send its employees to work the booth, plus the cost of the booth itself, and divide it by the limited number of hours that the trade show floor is open, you quickly realize that each hour is precious.
Your time is valuable, and certainly their time is valuable also. Let's not spend too much time on a single lead, but rather capture the information, end the conversation, and move on.
If you are working a booth at IBM InterConnect, or plan to work a booth at an event later this year, I highly recommend getting this book! It is available in a variety of hard copy and online formats at [ThreeFeetBook.com].
