Knowledge ManagementStorage Tiering
Tiered storage segments data based on its varying business value. The aim is to control storage costs and simplify data management. The trick is to match the data's relative value to the particular tier -- placing more recent or valuable data on the faster and more reliable storage, while relegating the older, less valuable or less frequently accessed data to slower, less expensive storage.

Single Array:
Lumenate Technical Consultants make tactical/strategic plans around your current storage and business continuity requirements to determine the best solution for your Tiered Storage solution.
- Fibre Channels provide a high-performance, high-speed switched storage network using dedicated host, switch and storage hardware OR
- SATA hard disk drives are quickly becoming alternatives to higher cost Fibre Channel (FC) and SCSI drives for enterprises grappling with new compliance requirements and considering tiered storage strategies.
Multiple Array:
- Virtualization is rapidly become a highly-productive standard for the enterprise customer. While it means substantial savings in hardware, real estate and electricity for bottom line-conscious CIOs, it also delivers an unprecedented level of flexibility and responsiveness for IT departments.
Recent Tiered Storage Implementation:
- Tier 1 data (such as mission-critical, recently accessed, or top secret files) was stored on expensive and high-quality media double-parity RAIDs (redundant arrays of independent disks).
- Tier 2 data (such as financial, seldom-used, or classified files) was stored on less expensive media in conventional storage area networks SANs).
- As the tier number increased, cheaper media could be used.
- Thus, tier 3 in a 3-tier system contained event-driven, rarely used, or unclassified files on recordable compact discs (CD-Rs) or tapes.
To realize the true benefits of tiered storage--and to take a big step toward ILM--you have to align data with its business value.
