There were several break-out sessions on the second day of the [IBM System Storage Technical University 2011] related to Cloud Storage.
- Storage for Cloud Computing
Clod Barrera is an IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage. He predicts that by 2015, 10 percent of the servers and storage purchases, as well as 25 percent of the network gear purchases, will be related to Cloud deployments. Cloud Storage is expected to grow at a compound annual growth rate (CAGR) of 32 percent through 2015, compared to only 3.8 percent growth for non-Cloud storage.
Cloud Computing is allowing companies to rethink their IT infrastructure, and reinvent their business. Clod presented an interesting chart on the "Taxonomy" of storage in Cloud environments. On the left he had examples of Storage that was part of a Cloud Compute application. On the right he had storage that was accessed directly through protocols or APIs. Under each he had several examples for transactional data, stream data, backups and archives.
Clod feels the only difference between Private and Public clouds is a matter of ownership. In private clouds, these are owned by the company that uses them via their private Intranet network. Public clouds are owned by Cloud Service providers and are accessed over the public Internet. Clod presented IBM's strategy to deliver Cloud at five levels:
- Private Cloud: on-site equipment, behind company firewall, managed by IT staff
- Managed Private Cloud: on-site equipment, behind company firewall, managed by IBM or other Cloud Service provider
- Hosted Private Cloud: dedicated, off-premises equipment, located and managed by IBM or other Cloud Service Provider, and access through VPN
- Shared Cloud Services: shared, off-premises equipment, located at IBM or other Cloud Service Provider, managed by IBM or Cloud Service provider, and access through VPN. The facility is intended for enterprises only, on a contractual basis, and will be auditable for compliance to government regulations, etc.
- Public Cloud: shared, off-premises equipment, located and managed by IBM or other Cloud Service provider, targeted to offer cloud compute and storage resources, with standardized platforms of operating systems and middleware, for individuals, small and medium sized businesses.
As with storage in traditional data center deployments, storage in clouds will be tiered, with Tier 0 being the fastest tier, to Tier 4 for "deep and cheap" archive storage. IBM SONAS is an example of Cloud-ready storage that can help make these tiers accessible through standard Ethernet protocols. Cloud Service providers will use metering and Service Level Agreements (SLAs) to offer different rates for different tiers of storage in the cloud.
Clod wrapped up his session explaining IBM's Cloud Computing Reference Architecture (CCRA). This is an all-encompassing diagram that shows how all of IBM's hardware, software and services fit into Cloud deployments.
- SONAS and the Smart Business Storage Cloud
This is a presentation I often give at the [IBM Executive Briefing Center] in Tucson, Arizona. I cover the following points:
- IBM positioning between its two strategic NAS products: N series and SONAS
- The history of SONAS, from Storage Tank and SAN File System to the Scale-out File Services offering
- How SONAS is designed differently than N series GX Cluster mode and other mount-point aggregators
- Independent Scaling of performance and capacity, allowing companies to design a solution that fits their particular workload characteristics
- World Record Performance results for a moderately-sized SONAS deployment, for a single file system entirely on spinning disk, based on SPECsfs2008 benchmark
- IBM's Smart Business Storage Cloud, which combines the base SONAS product with IBM services to offer unique solutions optimized for specific industries, clients and workloads
These sessions served as a preview for later presentations in the week that got into more detail on SONAS specifically.
