![]() As a result, most V-locity customers experience at least 50% faster application performance, with many workloads getting much more, depending on the extent of Windows write inefficiencies and how much memory is available. With as little of 2GB of available memory, many customers serve as much as 50% of their read traffic. Nothing has to be allocated for cache, since V-locity dynamically adjusts to only what is otherwise unused. Second, V-locity establishes a tier-0 caching strategy by using idle, available DRAM to serve hot reads. ![]() All of this is done with near-zero overhead to the CPU.įirst, V-locity eliminates xcessively small, fractured writes and reads, replacing them with large, clean contiguous writes, so more payload is carried with every I/O operation. Keith continued, “It wasn’t until we spoke with Condusiv® and heard what they did for other virtualized customers like ourselves that we began to consider the real root cause to our performance issues – small, fractured, random I/O characteristics that were akin to pouring molasses on our systems.”Ĭondusiv’s V-locity ® I/O reduction software is “set and forget” software that runs transparently in the background on Windows servers and automatically offloads I/O from underlying storage, then streamlines the I/O traffic that remains. We needed to see how we could maximize performance on the hardware we already had, which led to a conversation with Condusiv,” said Keith. No matter how well your business is doing, no one wants to have a million-dollar conversation that’s not in budget. “At the time, we thought our only solution was to invest hundreds of thousands of dollars into new all-flash arrays to get the performance we needed. Loan officers were complaining about slow queries taking five to ten minutes to run reports, and up to five seconds to advance from screen to screen within the loan origination system,” said Chuck Keith, Director of Infrastructure, Supreme Lending. As great as Nimble performs from a ‘cost per performance’ standpoint, it simply wasn’t enough with the growth of data and users we had been experiencing. “Our common workloads are supported by our older Dell Compellent arrays, but all of our MS-SQL workloads are supported by newer Nimble storage arrays. However, with the growth of users and data, Supreme Lending was pushing the I/O boundaries of their infrastructure and needed help. It’s the application their loan officers use daily to do their job efficiently and provide the best possible customer care. The most mission-critical application at Supreme Lending is their homegrown loan origination system that sits on top of a MS-SQL database.
