A lesson in flash caching
Solid-state storage is proliferating as a replacement for hard disk drives, where it offers a quick shift into the fast lane of storage processing. But flash can also be used with hard disks for a low-cost solution that delivers nearly equivalent performance. Using flash caching produces faster writes and even faster reads. But it’s important to know that there are three basic types of caching -- file-level, block-level and aggregated caching -- each with its own best-use case.
Object-storage is hot, with lots of buzz about how this new storage architecture offers enormous scalability, better file management and lower cost. We’ll tell you what it’s all about and how it might fit into your environment.
The results of our ninth annual Quality Awards survey for backup and recovery software are in; see which midrange and enterprise backup applications users have the most confidence in.
