Mango Announces Medley99 - The Next Generation 'Server'

Why Buy a File Server? Create One by Clustering Your Existing PCs

Westborough, MA - May 24, 1999: Mango, developers of breakthrough small business and enterprise solutions, today announced the release of their new software product, Medley99. Medley99 features Mango's second-generation Pooling™ Engine and Cache management with NT server class performance. Mango's new software product enables the creation of a "virtual file server" using idle capacity on existing PCs. As each PC is added to the "Pool™", files are instantly available, solving data migration problems. Medley99 combines advanced security, all standard file server features, and innovative clustering technology that provides superior fault tolerance.

Medley's strengths are best stated by Medley customers:

"About two months ago I had a system crash on me. We had to replace the Hard Drive. Everything was lost. When we put the network back on, all the info I had was still there. It was like Medley stored it in mid-air and put it back when the system came back on line." Loran Cheely PC Computers Plus.

Russell Bozian, consultant for the Cincinnati Association for the Deaf, says that the number one thing that impresses him about Medley is "that with any other file server system you are constantly worried about touching the server, you can't pull out cards or do anything that might mess up the system. With Medley I can walk around and fiddle with each machine whenever I want and the file system is always there." Russell claims that "once you use this file system all others seem like a toy".

"Medley99 is an incredible value for the small office that needs file sharing but does not want to perform complicated and time-consuming administration associated with network server solutions," says Mango's Vice President of Marketing and Sales, Eric Walton. "We know that 60% of all servers are purchased just as file servers, and Medley99 goes beyond simple file sharing, since it provides better performance than a traditional network file server because of its unique caching of data."

Walton also adds, "The very best way to reach the small business market is through the Value Added Reseller (VAR) channel and, therefore, Mango has decided to sell Medley99 exclusively through the VAR channel."

Medley99 makes a shared file server as easy to use as your local C drive, but has some of the advanced file features only available on more expensive systems. This includes fault tolerance similar to a clustered server and advanced performance features based on Mango's breakthrough caching techniques that migrate data according to usage. According to Mango's Vice President and Chief Technology Officer, Scott Davis, "Mango's Pooling Technology represents a breakthrough in cluster storage paradigms. It is a new hybrid model that incorporates the best attributes of the Shared Everything and the Shared Nothing cluster architectures, yielding superb load-balancing characteristics. Mango has uniquely applied enterprise clustering technology to meet the needs of the small business market."

Medley also smoothes the introduction of new PCs into workgroups. As a PC is added to the Medley "Pool", all the appropriate company data on the Medley drive simply appears to the new PC instantly, as another local drive. Since Medley uses existing idle capacity on PCs, the Medley virtual server grows as you add users, unlike a traditional file server.

Medley99 is shipping now exclusively through the VAR channel! VARs who are interested in distributing Medley99 should register at www.mangosoft.com on the Reseller page where they can obtain a trial version and details about Mango's VAR program. Medley99 supports Windows 95 and Windows 98 platforms, and requires 32MB of RAM and a pentium-class processor. It is designed for small businesses and organizations, as well as workgroups. Details are available at www.mangosoft.com.

Mango introduced Pooling™, Mango's unique and innovative clustered caching software, with its first product Medley™97. Medley99 includes Mango's vastly improved second generation pooling engine, which has led to significant performance and quality improvements. The Medley product provides an intuitive file system for the small business market and makes the networking of PCs simple and substantially more cost-effective than any other available alternative. Medley has won PC Week's Best of Comdex award for Connectivity Solutions. Technology pundit and Ethernet inventor Bob Metcalfe calls Pooling "the biggest idea we've seen since network computers." Mango has filed for eight patents on its Pooling technology and Mango's highly experienced engineering team is continuing to enhance this core technology and broaden its application. According to Davis, "Mango is already applying clustered caching to Web Caching and other Internet applications."
