ZFS is designed with a focus on data integrity, and uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors, effectively protecting users data.
Deduplication and compression to maximize VDI storage performance
All-flash storage featuring high-performance random I/O is advantageous for databases, online transaction processing (OLTP), and virtual desktop infrastructure (VDI) applications. Though the cost of all-flash storage is higher than using normal hard drives, data deduplication and compression technology can greatly assist in storing more data in less storage space with greater cost-efficiency and performance gains. Using VDI for example, there could be over 90% duplicate data from OS images and applications that are spread over virtual desktops. The TES-1885U supports block-based data deduplication to optimize storage usage from redundant data. Deduplicated virtual desktops become easier to be cached to achieve optimal virtual desktop performance. In-line data compression helps shrink data size, further optimizing storage usage.
