16Data Access Requirements are Always Changing Inferred by business use The reaility is the information lifecycle is dynamic. Data may need to be recalled at various times in its lifecycle, in a very unpredictable manner. Examples are when a mortgage is refiananced or when a patient gets sick, records would need to be recalled, and would need to be accessed quite often for a period of time. It may not be effective to have this data stored on secondary or archived storage solutions..The problem is that most ILM strategies move data in one direction only, from primary to secondary or tertiary storage. In a traditional ILM strategy, when data moves to tape, it stays on tape, even if the data goes active again. When users recall a file, they are either accessing it on tape and getting less-than-optimal performance, or they make a new “active” copy of the file, contributing to data sprawl.Sources: Horison Information Strategies, StorageTek1616

18Archive Requirements Are Changing The dynamic nature of data is also changing the nature of archive...in the past archive meant data was protected for the purpose of recovery- data was saved to tape, which was later moved to an offsite location- and only recalled when there was some type of failure.Because of the high costs of storing data- more and more organizations are utilizing archive solutions- disk or tape for storing “persistent” data- that which is not accessed often but cannot be moved offsite for long term archive.Compliance regulations which require that particular data be accessed ithin a set period of time also drive the need for intelligent” archive devices that can quickly search for and retrieve specific data sets.

44‘Infinite Disk’ Technology SAM-FS creates a virtualized or “infinite disk” that extends primary or secondary storage onto any number of additional media and devices.Virtualization optimizes storage capacity – automatically migrating inactive data to near-line secondary media – while also giving users immediate access to ALL of their data, regardless of where it is stored.Free SpaceActive Data (Frequently-Used Files)Pointers to Inactive Data on Secondary Media

There is a data policy that is defined during setup that governs how often this function runs, what tiers of storage it is to use, and how much storage resource is available for the archive function (ie 2 tape drives, 3 tape drives, etc.).Data policies governing the behavior of the ARCHIVE function can be established by application, by file system, by directory, even by file size and file type.The ARCHIVE function is transparent to the application being managed. Up to 4 tiers of storage can be populated with newly created or updated data. The data is written in TAR format which is important for worse-case scenarios where the application environment has to be rebuilt with nothing more than the data itself being available.This approach to data management enables users of ASM to automate the data protection and business continuance function.The ARCHIVE function can be set up to run on a specific time interval (ie once an hour), or at a specific time (ie 6pm each evening), or based on a specific application event (ie end-of-day process). There is a shell command for manual execution as well.Off-Site Storage

It’s function is to automate the space management function for primary disk. These data policies can be changed on the fly. The customer can even have one set of data policies set to run during normal business hours and have a completely different set of policies, usually to reallocate shared resources, for off-hour operations.Freeing up primary disk space can be accomplished as copies of the primary data are created, or at specific watermarks. The policies for the RELEASE function can even be set up to “Never Release” certain critical data that is under ASM’s control, populated to secondary storage, but must remain on disk at all times.As mentioned for the ACHIVE function, the ASM administrator can manually run the RELEASE function from any ASM master console.Off-Site Storage

This enables much improved response time from an end-user perspective. Without this ASM feature, the user would have to wait for the entire file to be restored to disk before any part of it could be accessible.Off-Site Storage
