    Preface This manual describes how to maintain the hardware for PS6010 storage arrays. Each array contains hot-swappable power supply and cooling modules, eight or sixteen RAID-protected disks, and single or dual hot-swappable control modules. With one or more PS Series arrays, you can create a PS Series group—a self- managing, iSCSI storage area network (SAN) that is affordable and easy to use, regardless of scale.

  • Page 22: Replacing Disk Drives

    PS6010 Hardware Maintenance Maintaining Disks • You can use disk drives with different sizes in an array. However, the smallest disk drive in the array will determine how much space can be used on each disk drive. For example, if the smallest disk drive is 400GB, only 400GB of space will be available for use on each disk drive.
