This document describes the full compliance of Condusiv® Technologies V-locity® I/O Reduction Software against the Microsoft® SQL Server® I/O Reliability Program Review Requirements.
Microsoft developed the SQL Server I/O Reliability Program to ensure the reliability, integrity, and availability of vendor products with SQL Server. The program includes a set of requirements that, when complied with, ensure the product is fully reliable and highly available for SQL Server systems. The program does not require or show performance characteristics of products, but it does require some I/O testing (Core 1.08) to exhibit the reliability and integrity of the product.
Condusiv Technologies’ V-locity is the product that is being documented for compliance with the SQL Server I/O Reliability Program. V-locity is a transparent, “set it and forget it” software-only solution that solves two big I/O inefficiencies. First, it enforces large, clean, contiguous writes and reads, so more payload is delivered with every I/O operation, reducing the number of I/Os to perform the same workload. In addition, V-locity further reduces I/O to storage by caching hot reads from idle, available DRAM. Nothing has to be allocated for cache since V-locity dynamically adjusts to only what is otherwise unused. If a system is memory constrained, V-locity’s caching engine backs off entirely.
