About HyperCache

Note    The following applies to Meridian 64-bit editions when run on a Windows 64-bit operating system only. For information about optimizing performance of 32-bit editions when run on a Windows 32-bit operating system, see About the High Performance Option.

Because the 64-bit platform provides a vastly larger memory address space and server computers with large amounts (16 GB or more) of physical memory are readily available and affordable, Meridian performance and scalability can be improved with an optimal configuration called HyperCache. HyperCache has become the default configuration for the Meridian Enterprise 64-bit platform.

HyperCache does for 64-bit vaults what the High Performance Option does for 32-bit vaults. In the HyperCache configuration, vaults are loaded entirely into memory. This maximizes the performance of these vaults, which typically serve larger numbers of users and higher document quantities. The contents of the HyperCache are saved in Hypertrieve databases between service shutdowns and startups for the fastest possible loading. The vault contents are replicated to repositories hosted by SQL Server or Oracle where they can be accessed with the Meridian Explorer client or standard reporting tools such as SQL Reporting Server and Crystal Reports.

Performance tests in simulated customer environments have shown HyperCache can improve performance significantly. Stress tests have shown that Meridian Enterprise 64-bit with HyperCache can manage 1.5 million documents (not counting revisions) and over 200 concurrent users while still providing good performance.

Earlier versions of Meridian Enterprise have been used mostly with up to 0.5 million documents (not counting revisions) and up to 100 concurrent users.

Note    While these tests have been executed on hardware and software configurations that resemble typical customer environments, they cannot be taken to be representative of any particular customer environment. Therefore, in cases of more than 0.5 million documents (not counting revisions) and/or more than 100 concurrent users, we strongly recommend having the hardware and software configuration reviewed by BlueCielo ECM Solutions or your BlueCielo Partner.

We recommend HyperCache configuration for all customers, but particularly for those with the following scenarios:

• Existing systems with performance or scalability problems.
• Customers planning to significantly expand their number of users or documents in the near future.

Implementing HyperCache requires:

• 64-bit CPU server computer
• Adequate physical memory (greater than the sum of the sizes of all vaults stored in Hypertrieve)
• Microsoft Windows Server 2003 or 2008 or higher
• Additional requirements as listed in Recommended server specifications
• BlueCielo Meridian Enterprise 2012 or higher
• Creation of Hypertrieve and Meridian Explorer databases
• No new system administration tasks

To calculate the amount of physical memory required for existing Hypertrieve vaults, add the size of all vault database files together and round up to the next largest memory configuration available for the server computer. To calculate this amount for existing SQL Server or Oracle vaults, add half the size of all vault database files and round up.

Assuming the closest available memory configurations for the server are 6 GB and 8 GB, select the 8 GB configuration at a minimum.

Assuming the closest available memory configurations for the server are 8 GB and 12 GB, select the 12 GB configuration at a minimum.

Creating a HyperCache configuration is described in the following topics.
