摘要： Technologies are described for implementing a migration mechanism in a data storage system containing multiple tiers of storage with each tier having different cost and performance parameters. Access statistics can be collected for each territory, or storage entity, within the storage system. Data that is accessed more frequently can be migrated toward higher performance storage tiers while data that is accessed less frequently can be migrated towards lower performance storage tiers. Each tier can be associated with a range of ILM statistics referred to as the bucket for that tier. A pivot table may be provided that relates the tiers and the buckets. Operations on the pivot table can provide counts of how many territories may be promoted or demoted between any two pairs of tiers.

摘要： According to one aspect, a computer-implemented method for managing at least one network interface of a computer system is disclosed. In one embodiment, the method includes the steps of executing of a boot loader to initialize a dedicated network interface and a side-band network interface, determining if a boot loader priority setting designates a preference to use one of a detected dedicated network interface or side-band network interface, determining if preferred network interface is available for use, then passing the priority setting to an operating system to use for network communications during run time.

摘要： A method, computer-readable medium, and apparatus for debugging a computer program utilizing breakpoints triggered by accessing a rarely used or unused I/O port is provided. Rarely used or unused I/O ports are identified in a computer system and a debugger program is instructed to halt program execution when an access is made to one or more of the identified ports. An instruction for writing to one of the ports is then inserted in the program to be debugged. When the instruction is executed, the debugger program will cause the execution of the program to stop. When the breakpoint is no longer needed, the debugger program is instructed not to halt when an access is made to the I/O port.

摘要： A method, system, apparatus, and computer-readable medium are provided for taking snapshots of a storage volume. According to aspects of one method, each snapshot is represented as a unique sequence number. Every fresh write access to a volume in a new snapshot lifetime is allocated a new section in the disk, called a provision, which is labeled with the sequence number. Read-modify-write operations are performed on a sub-provision level at the granularity of a chunk. Because each provision contains chunks with valid data and chunks with invalid data, a bitmap is utilized to identify the valid and invalid chunks with each provision. Provisions corresponding to different snapshots are arranged in a linked list. Branches from the linked list can be created for storing writable snapshots. Provisions may also be deleted and rolled back by manipulating the contents of the linked lists.

摘要： Technologies for efficient synchronous replication across heterogeneous storage nodes can provide the performance of high-speed storage units while leveraging low-cost and high-capacity backup storage units within the same system. The performance of low-cost, high-capacity hard disks may be improved by initially storing data into sequential physical locations. A sequential journal of I/Os may be used in a replicated secondary node to allow for rapid completion of I/Os. A separate background process can later scatter the sequentially logged I/O data into its proper location for storage. A programmable n-way router can be configured to route I/Os as needed to improve overall performance of the storage unit. A secondary node log device can also be used to provide continuous data protection (CDP). Lastly, packetizing together I/Os prior to delivery to a secondary node may reduce interrupts and context switches in the primary node, thereby improving performance of the storage system.

摘要： Techniques for continuous data protection can include creating snapshots of one or more underlying storage volumes upon specific file system events. Generating snapshots upon every file close event can protect the files in a storage system by keeping a snapshot of every version or modification of each file. Removal of redundant snapshots can mitigate the impact on storage capacity associated with creating these large numbers of volume snapshots upon each file close event. Additionally, file closure lists can be employed to allow generating snapshots only when a previously closed file is reopened. Such an approach can protect the previous version of a file prior to the opening of a new version of the file. Such an approach can also mitigate storage capacity impact without the creation of redundant snapshots.

According to one embodiment, the system includes a disk drive carrier cage configured to receive a disk drive backplane and up to eight pair of disk drive carrier rails. The disk drive carrier cage is sized for insertion into a drive bay having the dimensions of two optical mass storage devices compatible with a 5.25 inch form factor. The system also includes a disk drive backplane for receiving up to eight hard disk drives, disk drive carriers for holding the hard disk drives, and disk drive carrier rails mountable within the disk drive carrier cage for slidably receiving the disk drive carriers. The disk drive carriers and disk drive carrier rails are translucent thereby permitting light emanating from the backplane to be viewed at the front of the cage.

摘要： Methods, apparatus, and computer-readable media for providing a device handle database in an EFI environment are disclosed. According to one method, a device handle database is created for storing data identifying the protocols that have been installed on one or more device handles. The database includes a sorted array of elements utilized to store protocol data for a family of protocols having the same GUID. Each element in the array comprises a family data structure including a field for storing the GUID for the family along with a field for storing a pointer to a linked list that stores the protocol instance data for each of the protocols in the family. Each node in the linked list is also a member of a linked list for storing protocol data for all of the protocols installed on a given device handle.
