SANTA CLARA, Calif.—A spinoff from Denali Software Inc. officially announced its formation and rolled out a cache storage software technology during the Flash Memory Summit here Tuesday (Aug. 17).
The startup, called Nvelo Inc., was part of Denali until six weeks ago, when the intellectual-property (IP) house was acquired by EDA provider Cadence Design Systems Inc. Then, at that time, the group was spun-out into a new and independent company.
The group that would eventually form Nvelo has been developing a software storage technology within Denali since 2007, said Jiurong Cheng, president and CEO of Nvelo (Santa Clara, Calif.).
The startup has 15 employees and its investors include Cadence and Denali. Prior to Nvelo, Cheng served as the vice president of software engineering during his 12 year tenure at Denali Software.
Nvelo is in the process of rolling out its first product, which claims to bring new intelligence into storage subsystems and break the I/O bottleneck in today's computing systems. "The bottleneck is not going away," Cheng told EE Times at the Flash Memory Summit here.
The company's product, dubbed Dataplex, "is a new software product that increases the overall performance of your computer by using a small SSD as a high-performance 'cache' for your existing HDD."
The product enables SSD performance across the full storage capacity of a HDD—at a fraction of the cost of a full-sized SSD, according to the company.
"Dataplex continuously performs real-time analysis on the way 'you' are using 'your' applications and data, and automatically keeps those files ready on the SSD for optimal performance," according to the company. "In a typical PC configuration, Dataplex delivers 95 percent SSD performance by using as little as 16GB of SSD in conjunction with your standard HDD."
Robeson and Microsoft's technology never made it. NAND cache became DOA. But at the Flash Memory Summit this week, there is a lot of talk about NAND cache. Many agree it's very complex. ''How do you sell it to consumers?'' asked one expert. Thoughts out there?
As you mentioned, there have been a few attempts at NVM Caching for PC's. Each one of these suffered from one or more of the following "requirements" for effective caching:
1. you need to have sufficient cache capacity - 16GB is a good sweet spot for client/PC computing
2. your cache device (small SSD) must be sufficiently faster than your HDD (No thumbdrives or SD cards)
3. you need intelligent software to manage the cache algorithms and policies
