    • A computer system has a backplane including a SCSI (small computer system interface) bus for connecting a host processor to a number of disk drive units. The bus operates in a conventional manner to set up a connection, until the stage where the initiator selects a target. Then backplane control logic intervenes, and isolates all units on the bus other than the initiator and the target. Isolation is achieved by means of a set of bus switches on the backplane, controlled by the backplane control logic. This ensures that data transfer takes place over a simple one-to-one connection, reducing bus capacitance and reflections. The backplane also includes power switches that can be operated to power down any disk unit while it is being hot-swapped, and LEDs to indicate when it is safe to hot-swap a disk unit.
    • 计算机系统具有背板,该背板包括用于将主机处理器连接到多个磁盘驱动器单元的SCSI(小型计算机系统接口)总线。 总线以常规方式运行以建立连接,直到发起者选择目标的阶段。 然后背板控制逻辑干预,并隔离总线上除了启动器和目标之外的所有单元。 通过底板上的一组总线开关实现隔离,由背板控制逻辑控制。 这确保数据传输通过简单的一对一连接进行,减少总线电容和反射。 背板还包括电源开关,可以在热插拔时将任何磁盘单元断电,并指示LED可以安全地热插拔磁盘单元。

    • Systems and methods for determining impact of a backup job on virtual storage resources are disclosed. An exemplary method includes determining an estimated performance and logical/physical capacity for the backup job on a virtual library storage (VLS). The method also includes determining an actual performance and logical/physical capacity without the backup job. The method also includes determining a simulated performance and logical/physical capacity based on the estimated and actual performance and logical/physical capacity. The method also includes comparing the simulated performance and logical/physical capacity to a threshold.
    • 公开了用于确定备份作业对虚拟存储资源的影响的系统和方法。 示例性方法包括确定虚拟库存储(VLS)上的备份作业的估计性能和逻辑/物理容量。 该方法还包括在没有备份作业的情况下确定实际性能和逻辑/物理容量。 该方法还包括基于估计的和实际的性能和逻辑/物理容量确定模拟性能和逻辑/物理容量。 该方法还包括将模拟性能和逻辑/物理容量与阈值进行比较。
