What Temperature is Your Data?
This summer temperatures are soaring. Is your data storage running hot, too? There are varying degrees of data temperature; however, most data is cold. How this temperature is gauged is based on access activity. Studies show that after data is stored, 80 percent or more goes untouched. That’s cold! If you don’t delineate between hot, cool and cold data, you’re wasting space and storage dollars. In this BlogBytes we will help explain data temperatures and show how LTO technology can help you save a bundle in the process.
What is Hot and Cold Data?
Hot data is information that is accessed frequently, needed to make quick business decisions and usually stored on fast, expensive technology like flash storage. Cool or cold data is information that is accessed less frequently and can be stored on less expensive storage systems. It’s important to know where your data fits on the spectrum as you segment your data into storage groups. Groups can be based on business or security requirements, service level agreements, as well as regulatory needs. Other classifications, such as access frequency, should also be considered. For example, medical records may require encryption to comply with regulatory requirements and may be deemed cool or cold data as the regularity of access can be infrequent. This type of data could be stored on LTO-7 technology with LTO data encryption and quickly repurposed to flash or hard disk storage when needed.
A Different View of Data Temperature
Another way to look at data temperature is the long-held standard in which current data is hotter and of most value to the organization. Eventually this data ages and drops in temperature. When the data drops in importance or value, it should be transferred to storage layers that are less expensive. The underlying principle, data life cycle management, is that the importance or value of the data should correspond with the cost of the technology used to store it.
Keep Cool – Pair LTO Technology with LTFS and Flash
There’s no reason to keep infrequently accessed data on high cost storage. Move it to tape! The pairing of LTO tape technology with the Linear Tape File System (LTFS) can make moving data from flash to tape – and back again – a very manageable process. The practice of moving data based on its temperature helps efficiently maintain control of storage costs. LTFS is a self-describing tape file system that enables tape media to be mounted in a tape drive and read by the operating system, making it easy to utilize in a manner like using a USB drive or disk. LTFS is also an ISO industry standard. LTO-LTFS implementations can be as simple as a single tape drive, small to large tape libraries, or as part of an integrated tiered storage system with flash and hard disk. In this environment, data can move seamlessly between tiered layers based on data groups and policies. This storage strategy can help make data available as needed, while still managing storage costs. Here’s a list of LTFS provider implementers.
