IBM Total. Storage® Logical Steps To Implementing ILM – Compliance and Tiered Storage § Step 1: Planning and Assessment – – – Identify, evaluate, predict trends Data categorization Establish policies Knowing your data § Step 2: Active Data Management – – – Virtualise physical storage Pooling of storage by class of service Policy based file allocation and placement Policy based file migration Simplify and consolidate file systems Automation and Efficiency § Step 3: Inactive Data Management – – 4 Business continuity Email, Database, File Archive Retention or destruction Long term retention for compliance IBM Total.

IBM Total. Storage® What is the SAN Volume Controller (SVC)? § The SVC is a Block Storage Virtualisation product § The SVC is an Enterprise-class Storage Server § The SVC consists of pairs of tightly-coupled nodes for performance & high availability § The SVC allows storage systems from different vendors to co-exist in the same virtual ‘pool’ of storage § The SVC is NOT a RAID controller 5 IBM Total.

IBM Total. Storage® Architectural Differences – General Observations § Customers don’t buy based on theoretical differences, they buy proven implementations that solve their problems § Advantages of SVC implementation of cached appliance – – – Modular design – flexible for customers, not tied to monolithic arrays or Director-switches SAN agnostic – interoperates with existing SAN fabric Horizontal scaling – low entry cost yet grows to large Data Centres Proven HW platform – Failover based on proven storage controller designs Cache for network-based copy services and to balance across disparate storage § Theoretical concerns overcome by SVC implementation – – Performance Optimised SW Stack means additional latency in the worst case of 60 microseconds ~0. 5% degradation Efficient cache algorithms means improved performance for many customers 155, 000 SPC-1 Benchmark far exceeding virtualisation alternative or traditional arrays Scalability Horizontal scaling while maintaining a common storage pool – unique in the industry Linear scaling in IO/s and bandwidth submitted with SPC-1 Benchmark 100 X scaling proven with customers from a few Tera.
