摘要:
A multi-city wavelength link architecture is used to distribute spectral bands received on input optical signals among output optical signals. Such an architecture may include an optical wavelength cross connect having multiple input ports, multiple output ports, and a wavelength routing element that selectively routes wavelength components between one optical signal and multiple optical signal. Such an optical wavelength cross connect will generally receive cross-connect-input optical signals at the input ports and transmit cross-connect-output optical signals from the output ports. Methods are used to increase the number of cities that may be accommodated by the architecture without disrupting through traffic between the existing cities.

Embodiments provide systems and methods for maintaining immutable data in an archiving system using random access memory. To ensure data is immutable, novel pointers are maintained in the hardware/firmware of the drive ports and on the removable disk drives. For example, a hardware/firmware in a modular drive bay maintains a pointer to a memory address in the removable disk drive memory that cannot write to a memory block that precedes the pointer. Data may only be stored after the pointer in the removable disk drive. As such, once data is written to the removable disk drive, the data cannot be overwritten although the removable disk drive employs random access memory.

Embodiments of the present disclosure provide a unique and novel archiving system that includes two or more network storage systems, each network storage system including removable hard disk drives embedded in removable disk cartridges, referred to simply as removable disk drives. The removable disk drives allow for expandability and replacement such that the archiving system need not be duplicated to add new or more storage capacity. In embodiments, the archiving system accesses, writes, reads, or performs functions on data from one network storage system to another remote network storage system.

A data storage system for removably storing information is disclosed. The data storage system includes a cartridge receptacle adapted to electrically and mechanically engage a removable data cartridge. The cartridge receptacle includes a second electrical connector and a conductive member. The second electrical connector is adapted to electrically engage a first electrical connector of the removable data cartridge. The conductive member is configured to engage a resistive portion of the removable data cartridge before the first and second electrical connectors engage. The conductive member is coupled to a ground of the cartridge receptacle.

According to the disclosure, a unique and novel archiving system that allows the digital shredding of archived data is disclosed. Embodiments of the archiving system include removable disk drives that store data, which may be erased such that the data is considered destroyed but that allows the removable disk drive to be reused. The archiving system can determine which data should be erased. Then, the data is digitally shredded such that the removed data cannot be retrieved or deciphered. In alternative embodiments, a protection may be placed on the data required to be kept because the data is associated with a legal suit. This “legal hold” prevents the data from being digitally shredded. As such, the archiving system can provide a system that can dispose of data on a file-by-file or granular level without physically destroying the media upon which the data is stored.

A telecommunication device for receiving and transmitting DS1 level signals that includes a 1/0 digital cross-connect switch, a GR-303 concentrator, and a frame relay aggregator switch in a single integrated device in one housing that fills less than two standard rack units. The device includes both active and standby/backup controller cards that communicate with eight quad framer cards through a bus located in the backplane. The communication through the backplane is via a 8.192 Mbps signal to and from each quad framer card, passed along a bus. The 8.192 Mbps signal is generated by multiplexing the four DS1 (E-1) signals on the quad framer card. The controller card that is active monitors the status of the DS1 channel associated with each framer and stores historical data about the status in spare buffer registers on each framer. Whenever a transition occurs to the standby/backup controller card, that card can obtain the historical status information from the framers to make the transition more seamless. The device also includes software that is interrupted on signaling bit changes, so that a software program can control a digital cross-connect of the signaling bits, and translation if necessary.

Systems and methods for storing and accessing data on a removable media having a changeable data set and an immutable data set. In one embodiment, a system can comprise a removable media storage system adapted to determine whether a host system running one or more applications is configured to enforce Write Once Read Many (WORM) policies. The host system can be communicatively coupled with the removable media storage system and configured to execute instructions causing the host system to determine whether to allow or deny a request to access data on the removable media. The host system can use rules to determine if an access request is to access data of a changeable data set or a immutable data set. If the request is to access data of the changeable data set, access is allowed. If the request is to access data of the immutable data set, reads are allowed, as well as writes of new data. Access requests to rename, delete, and/or write to existing data of the immutable data set are denied.

According to the disclosure, a unique and novel archiving system that provides one or more application layer partitions to archive data is disclosed. Embodiments include an active archive including a fixed storage. The active archive can create application layer partitions that associate the application layer partitions with portions of the fixed storage. Each application layer partition, in embodiments, has a separate set of controls that allow for customized storage of different data within a single archiving system. Further, embodiments of methods for ensuring storage capacity in the active archive and the application layer partitions within the active archive is also disclosed.
