Get your Data on the Right Level. The benefit of Tiered Storage Strategies.

Tiered storage strategies offer organizations several benefits. The options available today can help determine what data  goes where, or in other words, where to put it so that they’re optimizing on performance, cost and security. In this BlogBytes we’ll discuss the current strategies of storage tiering and how LTO technology plays a key role. Let’s do this!

Users of business websites, applications, and files expect them to load instantaneously. For example, online shopping, and transactions depend on fast response times and if processing times are too slow, customers go elsewhere.

Not long ago, using flash arrays may have been an adequate option, but could’ve been too costly since not all data or applications required that type of technology investment. However, today there are varying types of Flash SSDs with different performance and cost structures that can be used in a tiered strategy along with LTO technology as a key partner.

Tiering Today

With the use of a tiered storage strategy, various categories of data are assigned to different types of storage media. Data most critical to daily operations is stored on the highest performing storage platform while less demanding applications are assigned to lower performance and less expensive media. This helps conserve investments while still addressing user demands.  As outlined in a recent SearchStorage article, storage tiering is necessary now more than ever. The article highlights that “today . . . we have different types of SSDs with varying performance and cost levels; a range of SSD flash interfaces from high-bandwidth, low-latency NVMe to low-bandwidth, high-latency SATA; and an upcoming generation of storage class memory technology.” The article points out that most access to data is within the first 72 hours of creation and falls off rapidly after that becoming very infrequently accessed after 30 days.

The article claims that “Higher performing higher cost storage tiers [are] reserved for the highest value data. Data [is then] moved from the primary performance tier to a lower one as it cools.” FLAPE is a good example of this approach in action: As long as the data is being accessed frequently, it can be recalled from flash and after the data is no longer accessed frequently, it gets moved to LTO tapes for long-term storage, providing secure storage at a lower cost with less power consumption.

Cool Data

Where should the cool and cold data go? LTO Technology has been shown to offer one of the lowest costs of ownership for long-term storage as outlined in this TCO study by ESG. Cost of storage is only one criterion; data security and long-term protection are also key concerns. Online flash disk data is susceptible to natural, human and system error or cyberattacks. One of the most effective methods for protecting data against cyberattacks is to keep it inaccessible from the network, which means keeping data offline. Tape storage is inherently offline and can be easily transported offsite and out of region for additional protection against a site-wide or regional disaster.

Protect it all on LTO

A tiered storage approach involving LTO technology can help control costs while addressing access demands.  Protecting the data is also vitally important, which is why using LTO tape technology to provide offline data security is a must.
