Abstract: The present invention will focus on detecting and fixing any potential technical search engine optimization issues in real-time. The required web page changes take place really fast, and made possible by RankSense's VELOZ web page virtualization engine described here. We list detailed fixing processes covering issues that could affect nine example SEO tags: 1. Canonical tags; 2. Redirects; 3. Robots tags; 4. Pagination tags; 5. Hreflang tags; 6. Rel alternate tags (mobile); 7. Vary header; 8. 40x/50x errors; and Search Engine Friendly URLs. In an example process, the Server Module replaces canonical tags on a virtual HTML stream in real-time based on real-time feedback from the Daemon Service or fast lookups to a prepopulated DBM file. A similar approach is taken to detect and fix the issues affecting any of the example SEO tags: redirects, robot tags, etc.

Abstract: A continuous media file server has a controller connected to multiple data servers. Each data server supports at least one storage disk. Data files are distributed across the data servers so that data blocks of the data files are stored on each of the storage disks according to a present striping layout. The file server employs declustered mirroring techniques in which data is redundantly copied and stored on other disks and servers to guard against component failure. In the event that the storage capacity of the media file server is changed (i.e., by adding or removing one or more storage disks), the continuous media file server is restriped in a three-phase process. During the first phase, the controller determines a new striping layout of the data files across the storage disks which accounts for the capacity change.
