IBM Systems Technical University Australia Day 3 Final Sessions
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University.
PowerAI overview and Cognitive Solutions on POWER
Anand Subramaniam, IBM Technical Specialist, presented this session on PowerAI. IBM packaged a collection of Machine Learning libraries, optimized them for POWER8 chip-set, and made this entire package freely available for download as "PowerAI".
IBM also is working on a priced value-add collection called "PowerAI Vision"
Hadoop Infrastructure solutions and Point-of-View
Alexis Giral, IBM Executive Storage Architect, presented the benefits of IBM Spectrum Scale using a simple example. Supposed you are gathering 40TB of sensor readings per day. How many TB of storage would you need to hold 2 years worth of data?
Traditionally, HDFS maintains three copies of the data. A recently added feature "HDFS-EC" provides erasure coding to reduce the overall storage requirements. Giral showed this chart:
5+4 Erasure Coding
Spectrum Scale ESS
8+3 Erasure Coding
And this is assuming all the data is hot. If you decide to keep only 30 percent hot, perhaps the most recent eight months, and the other 70 percent on colder storage, you may reduce your storage requirement costs even further.
IBM Cloud Object Storage - Redefining backup infrastructure
Maciej "Mac" Lasota, presented the use of IBM Cloud Object Storage as a backup repository. While IBM Spectrum Protect is the preferred choice, IBM COS also works well with Commvault and NetBackup.
He listed some of the challenges that companies have with backups to tape, and how IBM COS addresses these challenges.
(While IBM COS is three to four times more expensive than tape, it is a luxury many clients can now afford!)
He wrapped up the session showing five different deployments that he worked on for clients.
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:
IBM Easy Tier on DS8000 and Spectrum Virtualize to provide tiering within a system.
IBM Virtual Storage Center (VSC) to provide tiering between systems in a data center.
IBM Spectrum Scale, Spectrum Archive and IBM Cloud Object Storage System to provide global tiering across multiple locations, and across flash, disk, tape and cloud resources.
Spectrum Scale for Volume, File and Object Storage
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.
Beating Ransomware! A deep exploration of threat vectors for applications and storage
Andrew Greenfield, IBM Global Engineer for Spectrum Storage, presented on the threat of ransomware. In addition to being an expert in various storage, he also is an expert in security.
If you think security is just setting up your network firewalls and turning on data-at-rest encryption on your storage, you are sadly mistaken. Many of the treat vectors come from the inside, disgruntled employees or temporary contractors who plant viruses, bombs and worms that may not activate until long after they leave.
There are now products called security information and event management (SIEM) that provide real-time analysis of security alerts generated by network hardware and applications. Two that Andrew was familiar with were IBM Qradar and Varonis. These identify standard and abnormal behavior patterns among users.
Andrew feels products like Splunk do a great job to collect information, but don't do the analysis that Qradar or Varonis do.
I was very pleased with this conference. This was a concentrated 3-day event, but everyone I talked to was happy with the format, and felt their time spent worthwhile!
