Information Lifecycle Management is a strategic response to these trends Three things to remember about ILM: 1. Think policies, processes, practices, and tools not just products 2. Align business value of information with the most cost effective IT infrastructure 3. Alignment through management of service levels over time ILM is comprised of the policies, processes, practices, and tools used to align the business value of information with the most cost effective IT infrastructure from the time information is conceived through its final disposition. Information is aligned with business processes through management of service levels associated with applications, metadata, information, and data. Storage Networking Industry Association - SNIA 4

They asked IBM STG Lab Services to advise them on tactics for implementing ILM best practices. They stated the following key business objectives: Create a 3-5 year vision for storage infrastructure Control costs as they grow Implement more effective data management processes such as storage tiering, automation, consolidation and standardization Improve disaster recovery position Improve backup/restore position Increase efficiency in meeting compliance requirements Improve staff efficiency Effectively accommodate drivers of growth * To preserve confidentiality, the name and characteristics of this client have been changed. For clarity, many details have been simplified or omitted. 5
Case Study: ACME Corporation ACME utilizes SAN and internal direct attached storage (DAS) supporting a variety of server platforms. Two primary data centers plus other IT infrastructure located at various remote locations Primary server platforms are Intel, Unix and System z, running Windows, Novell, VMware, AIX, z/os Many stand alone servers are not connected to the SAN. Disaster Recovery through replication and data backup Overall storage growth rate is approx 50% per year, with primary growth areas in digital images and Windows applications Overall storage utilization varies from 25-65% for SAN storage, lower for DAS, higher for mainframe storage Substantial DAS capacity approximately 15% of total ACME data center storage topology 6
ACME maintains approximately 400TB of disk in data centers with substantial direct attached or internal storage capacity contained within servers. Storage tiering by performance and availability is not widely implemented in Open Systems. Remote mirroring for availability and disaster recovery is in use with plans for expanded coverage of mission critical applications Top-tier SAN Disk, one newer and several older High performance, RAID 1 Mixed 10k and 7200 RPM, mixed capacities Midrange SAN Disk Medium performance, RAID 5 Mixed 10k and 7200 RPM, mixed capacities Approx 950 servers with DAS Disk: 500 servers with internal DAS (120 >100GB) 300 with internal storage only (total 33TB) 150 with non-san external storage (total 24TB) All Data Center Storage (TB*) NAS/Other Mainframe SAN Internal DAS 242 40 9 112 Data Center SAN Storage (TB*) 3 - EMC 8530 4 - EMC Clariion 4 - EMC DMX 1000 DMX 3 41 42 30 29 7
In a Business As Usual (BAU) scenario, ACME would need 340TB of new disk and 1.6PB of new tape storage in the next three years, resulting in $15M of operating expenses! Projecting the current practices and disk growth going forward, ACME will need 75TB, 105TB, and 160TB in each of the next three years Tape Storage will also grow substantially BAU Annual New Disk Storage 500 TB 450 TB 400 TB 350 TB 300 TB 250 TB 200 TB 150 TB 100 TB 50 TB 0 TB BAU Disk Storage Growth New Disk Stg Start of Year Year 1 Year 2 Year 3 180 TB $ 4.5 M 160 TB 140 TB 120 TB 100 TB 80 TB 60 TB 40 TB 20 TB 0 TB Year 1 Year 2 Year 3 $ 4.0 M $ 3.5 M $ 3.0 M $ 2.5 M $ 2.0 M $ 1.5 M $ 1.0 M $ 0.5 M $ 0.0 M Costs to cover that disk infrastructure includes hardware, maintenance, and increased staff expenses for administration Not counting tape, disk-associated costs would total roughly $10M over three years BAU New Stg BAU Cost of New Stg 8
SAN disk virtualization enables ACME to lay the foundation for implementation of an ILM infrastructure. The IBM SAN Volume Controller (SVC) is designed to enable storage virtualization with improved resource utilization, storage administration and simplified provisioning: Pools storage devices into reservoirs of capacity for centralized management. Designed to provide non-disruptive capability for migration and technology upgrades. Scalability and high-end performance proven by references and comparative benchmarks. Work with various vendors products to enhance IT flexibility and avoid lock-in. Helps increase the amount of storage capacity that is available to host applications. Designed to improve overall utilization of storage hardware resources. 9
Disk virtualization enables ACME to organize and sustain a pooled, tiered storage infrastructure even as technology advances and data capacity grows. Opportunity to increase the current 25-65% utilization, and reduce future storage purchases by pooling capacity across storage controllers. In some cases data placement no longer reflects best practices, with a significant opportunity cost. Organize storage tiers to reflect the performance and availability characteristics needed by variety of business requirements. Data can be placed onto tiers and moved among tiers to match the workload profile with business value. Virtualization enables ACME to add new disk controllers and retire older controllers without disruptive or expensive migration projects.

Storage management solutions should automate or assist data movement to maintain optimization and control cost IBM TotalStorage Productivity Center helps ACME to: Understand how storage across multiple systems is used so that classification and placement can be implemented. Define policies to detect usage patterns and take actions such as alerts, scripting, file archive or deletion. Identify, evaluate, control, and predict enterprise storage management needs. Centrally monitor and manage SAN storage from a variety of vendors IBM Tivoli Storage Manager is designed to: Stage backups to disk pools, and then transfer disk pools to tape to reduce backup windows. Manage the number of backup and archive copies of objects to reduce duplication on backup media. Interoperate with virtual and physical point-in-time data copy operations, as well as virtual tape libraries, to optimize the use of resources. Tivoli Storage Manager for Space Management (HSM) can move seldom-accessed files to lower cost storage automatically, and transparently recall them as needed. Princeton Softech can archive structured application data onto less expensive storage tiers as the data ages, to control cost and avoid unbounded data growth. 12

Disk virtualization synergy in top disk tiers To recap: A major goal of storage optimization and virtualization, in executing an ILM strategy, is to reduce incremental growth of top-tier storage capacity! However, a top-tier disk system such as the IBM System Storage DS8000 has strong synergy with virtualization and storage tiering. The DS8000 complements virtualization and tiering: Intermixable disk drive packs offer a range of performance characteristics and cost per TB: 73GB, 146GB, and 300GB 15k RPM FC; 146GB and 300GB 10k RPM FC 500GB 7200 RPM FATA Low-cost FATA drives can be a good fit for near-line or archive disk, fixed content data, or secondary disaster recovery. Outstanding scalability from 1.1TB up to 512TB. Logical partitioning (LPAR) capability supports service class distinctions and workload partitioning Excellent storage management interoperation between IBM SAN Volume Controller, TotalStorage Productivity Center, and DS8000. 16
