There's a lot to know about tiered storage – from key management practices to designing a system that best fits your business' needs. Whether you're new to the concept, looking for ways to implement it on a tight budget or a storage pro, our Tiered Storage Fast Guide
Definition of tiered storage
Tiered storage is the assignment of different categories of data to different types of storage media in order to reduce total storage cost.
Definition of ILM
Information life cycle management (ILM) is a comprehensive approach to managing the flow of an information system's data and associated metadata from creation and initial storage to the time when it becomes obsolete and is deleted.
Tiered storage has arrived
Storage managers are continuing down the paths they indicated last March, if a little more cautiously, and those paths are leading toward a tiered environment.
Data classification: Getting started
How data classification can lead to higher service levels, a better working relationship with the business units that create and own the data, and the ability to reduce costs by storing data on an appropriate.
Tiered storage is a hot idea, but implementing it can be trickier than appears. This article defines the two different approaches -- heterogeneous and homogeneous -- and helps you choose the strategy you should employ.
Prime time for secondary storage
By definition, the word "secondary" suggests some degree of inferiority, but in a storage area network (SAN), secondary storage can bring big savings and smoother operations.
Tiered storage with SATA
Simply deploying low-cost storage doesn't always equal savings. Learn to calculate total cost of ownership (TCO) when planning tiered-storage system using lower-cost disk and save money.
Save money with tiered storage
The price differences between the classes of storage are becoming extreme. For example as of this year, you could pay more than $120 per gigabyte for high-speed, high-reliability storage systems, or you could pay less than $7 per gigabyte for a low-speed, less reliable solution using ATA disks.
Cost savings lure users to tiered storage
Many companies are finding cost savings and improved data management with a tiered storage approach. But before purchasing those midrange arrays, you'd better prioritize your data and study up on vendor interoperability, said users.
Strategic Storage: Five storage management musts
One thing's for sure about enterprise storage these days -- it's not getting any simpler. Storage managers must deal with constant data growth, as well as burgeoning corporate interest in keeping closer track of just what data lies where.
Managing tiered storage a pain in the neck
Tiered storage promises all kinds of goodies, not least of all a way to take advantage of lower cost disk while paving the way to some type of data lifecycle management process. So far, however, it's failing to deliver on this promise.
Fast Guide: Storage Management
Managing your storage infrastructure has never been harder. Complex systems, unbelievable data growth rates and squabbling vendors are just a few of the issues hampering your ability to manage storage.
