  • Optimizing a RAID volume
    Patent number: 8892939
    Abstract: Optimization of a RAID volume is described. In an example, a method of optimizing a redundant array of independent disks (RAID) volume includes: identifying a RAID level used for a plurality of disks in the RAID volume; defining a relation among rebuild rate, scrub rate, and annualized data loss event rate (ADLER) for the RAID volume using constant values and the RAID level; selecting a value for the ADLER; applying a policy to the relation to choose a value for one of the rebuild rate or the scrub rate; and determining a value for the other of the rebuild rate or the scrub rate from the relation using the value of the rebuild rate or the scrub rate as determined from the policy.

  • METHOD AND APPARATUS FOR DETERMINING TRAVEL TIME FOR DATA SENT BETWEEN DEVICES CONNECTED TO A COMPUTER NETWORK
    Publication number: 20010010059
    Abstract: An apparatus and method for determining transfer time and/or bandwidth between devices connected to a computer network includes sending a script or redirect signal to a browser attempting to fetch a banner from a server that causes a timer or clock to run between the initiation of a subsequent fetch page, fetch image, or other request by the browser and the delivery of subsequent data to the browser. The bandwidth of the device and/or the transfer time between the server and the device on which the browser is operating and the bandwidth of the device can then be used in the selection of which subsequent files, images, scripts, banners, executable software, or other content to be served to the browser or in the selection or configuration of web pages, electronic mail, or executable software to be served to the browser.
