Abstract: A sequence of fixed-size blocks defines a page (e.g., in a server system, storage subsystem, DASD, etc.). Each fixed-size block includes a data block and a footer. A high performance block storage metadata unit associated with the page is created from a confluence of the footers. The confluence of footers has space available for application metadata. In an embodiment, the metadata space is utilized to record a “write activity level” metric, and a timestamp. The metric indicates the write frequency or “hotness” of the page, and its value changes over time as the activity level changes. Frequently accessed pages may be mapped to higher performance physical disks and infrequently accessed pages may be mapped to lower power physical disks.

Abstract: Programming code embedded in an application automatically converts local client data to emulated HTML multi-part form data, without downloading a corresponding form from a web server. The selection of data for conversion is performed programmatically, without the need for interactive user specification of each data item. The emulated HTML multi-part form data is transmitted to a web server as a service request. Preferably, the client application is a configuration utility which generates a record of a computer system configuration, and the server performs the function of configuration verification on configuration data formatted as emulated HTML multi-part form data. The server concurrently maintains a web page which will, on request, download an HTML form corresponding to a system configuration to a web browser, from which a user may specify a system configuration to be verified.

In an embodiment, the metadata space is utilized to record a “write activity level” metric, and a timestamp. The metric indicates the write frequency or “hotness” of the page, and its value changes over time as the activity level changes. Storage subsystem performance may be enhanced by mapping frequently accessed pages to higher performance physical disks and mapping infrequently accessed pages to lower power physical disks. This approach is advantageous in that the metric is recorded on a non-volatile basis and may be readily communicated between system components (e.g., between a host computer and a storage subsystem).
