| 20110113259 | RE-KEYING DURING ON-LINE DATA MIGRATION - A method of migrating data comprises migrating source encrypted data from a source storage device to a target storage device and re-keying while migrating the source encrypted data. The method further comprises while re-keying and migrating the source encrypted data, performing an access request to the source encrypted data apart from the migrating and re-keying. | 05-12-2011 |
| 20110066909 | PLUGGABLE TRANSCEIVER MODULE WITH ENHANCED CIRCUITRY - Pluggable transceiver modules with additional functions and circuitry contained within the module. In a first embodiment, additional circuitry is added to determine bit error rates at the point of the module itself. This allows a much better diagnostic evaluation of location of problem. In an alternate embodiment, various logic is placed in the module. In a first alternate embodiment encryption/decryption units are placed in the converter module so that encryption and decryption operations on the serial bitstream do not need to be performed in a switch. Existing switches can be used but the interconnecting links can still be encrypted. A second alternate embodiment includes compression/decompression units placed in the module to allow effective higher throughput on the selected links. | 03-17-2011 |
| 20110058573 | USER SELECTABLE MULTIPLE PROTOCOL NETWORK INTERFACE DEVICE - An Ethernet/Fibre Channel network interface device which can be configured by a user to operate on an FC SAN, a CEE network or both. In one embodiment the configuration can be done using jumpers or connections to the pins of a chip, thus allowing a manufacturer to only inventory one device for use with either or both networks. In a second embodiment the configuration can be done in software by setting registers and memory values on the device. This embodiment allows the device to be changed between configurations without removing it from the server or blade. The devices according to the preferred embodiments further reduce power consumption by shutting down portions of the chip not needed based on the configuration of the device. | 03-10-2011 |
| 20110038477 | RE-KEYING DATA IN PLACE - A system comprises an encryption engine and a host processor coupled to the encryption engine. The host processor determines when a time period has expired for a unit of data. Upon determining that the time period has expired, the host processor causes the encryption engine to re-key the unit of data in place. | 02-17-2011 |
| 20100091780 | FRAME TRAFFIC BALANCING ACROSS TRUNK GROUPS - Embodiments of methods, apparatuses and/or systems for logical ports in trunking are disclosed. For example, a method of routing a flow of frames may include applying a correspondence between logical ports and physical ports of a switch. | 04-15-2010 |
| 20100088481 | WRITE CAPTURE FOR FIBRE CHANNEL FABRIC SNAPSHOT SERVICE - The snapshot capability moving into the SAN fabric and being provided as a snapshot service. A well-known address is utilized to receive snapshot commands. Each switch in the fabric connected to a host contains a front end or service interface to receive the snapshot command. Each switch of the fabric connected to a storage device used in the snapshot process contains a write interceptor module which cooperates with hardware in the switch to capture any write operations which would occur to the snapshot data area. The write interceptor then holds these particular write operations until the original blocks are transferred to a snapshot or separate area so that the original read data is maintained. Should a read operation occur to the snapshot device and the original data from requested location has been relocated, a snapshot server captures these commands and redirects the read operation to occur from the snapshot area. If, however, the read operation is directed to the original drive, the read is provided from the original data areas, even if the data had been replaced. The snapshot server determines the existence of particular snapshot devices, allocates their storage locations, provides this information to both the service interfaces and the write interceptors and handles read and write operations to the snapshot device. | 04-08-2010 |
| 20090219827 | REGISTERED STATE CHANGE NOTIFICATION FOR A FIBRE CHANNEL NETWORK - Disclosed herein are various aspects of a Fibre Channel (Fibre Channel) fabric having switches that employ Registered State Change Notifications (RSCNs) with enhanced payloads. Two types of RSCN message formats are provided, both including status information about the affected device(s). In one embodiment, a RSCN message format for inter-switch communication provides various information about the affected devices according to one of a plurality of predetermined formats. In another embodiment, a node device RSCN message format provides information about a port state, the identification of the affected port, along with the port and node world wide names and the FC-4 types supported by the node. | 09-03-2009 |
