  • Publication number: 20140012990
    Abstract: System and method for load balancing multiple file transfer protocol (FTP) servers to service secure FTP sessions having encrypted signals are disclosed. In one aspect, embodiments of the system include multiple FTP servers coupled to a load balancing agent. Each of the multiple FTP servers is associated with a unique port range and the load balancer receives an encrypted data signal in a secure FTP session on a given port and uses a port range within which the given port falls to identify which of the multiple FTP servers a corresponding control signal of the secure FTP session was previously sent.

  • Publication number: 20130124932
    Abstract: A Solid-State Disk (SSD) Manufacturing Self Test (MST) capability enables an SSD manufacturer to generate and load tests onto SSDs, run the tests, and gather results. The SSDs self execute the loaded tests when powered up. The self executing is while coupled to a host that loaded the tests or while coupled to a rack unable to load the tests but enabled to provide power to the SSDs. The rack is optionally cost-reduced to enable cost-efficient parallel testing of relatively larger numbers of SSDs for production. The host writes the tests to an ‘input’ SMART log of each SSD, and each SSD writes results to a respective included ‘output’ SMART log. The commands include write drive, erase drive, SATA PHY burn-in, delay, and stress mode. The SSD MST capability is optionally used in conjunction with an SSD virtual manufacturing model.

  • Patent number: 5146382
    Abstract: A floppy disk cleaning machine which has a locker to cause a cam above a link to compress a positioning plate for holding of a floppy disk, a sector wheel at an end of the link to drive a sector wheel at a driving rod which consequently disengage the cam from two rolling shafts which then cause two cleaning rods to hold the floppy disk at its read/write slots by action of a spring, and a motor with rubber shaft to drive a turn plate to rotate the floppy disk for cleaning purpose. The rolling shafts can be extended by the cam after the cleaning process for removal of the floppy disk from the cleaning machine.
