Figure 23 M6720 Drive Enclosure (4U24) Hard Drive Placement Order Guidelines for Allocating and Loading Order (Mixed SFF and LFF hard drives) In a storage system with mixed HP M6710 and M6720 drive enclosures, there is a minimum of three pairs of drives for each drive enclosure. Additional upgrades can include all SFF, LFF, or a mixture of SFF and LFF drives, but they must be in pairs of the same drive type. Follow the loading order as in the sections above for SFF and LFF drives. WARNING! If the StoreServ is enabled with the Data-at-Rest (DAR) encryption feature, only use the self-encrypting drives (SED). Using a non-self-encrypting drive may cause errors during the upgrade process. For information about adding drive enclosures, see "Adding Hard Drives and Expansion Drive Enclosures" (page 87). For information about encrypting the hard drives with an enhanced security feature known as Data-At-Rest (DAR) encryption, see "Enhancing Security with Data Encryption" (page 86). Installing a Hard Drive Before beginning this procedure, review how to load the drives based on drive type, speed, and capacity. See "Guidelines for Installing Hard Drives in Drive Enclosures" (page 24). NOTE: To avoid any cabling errors, all drive enclosures must have at least one or more hard drives installed before powering on the enclosure. CAUTION: Blank hard drive filler panels are provided and must be used if all slots in the enclosure are not filled with hard drives. CAUTION: To avoid potential damage to equipment and loss of data, handle hard drives carefully. Each hard drive includes a green and amber LED on the front to indicate hard drive status. Installing a 2.5 inch Hard Drive (SFF) 1. Press the handle latch to open the handle. 2. Insert the hard drive into the enclosure with the handle opened from the top in the vertical position. 3. Slide the hard drive into the enclosure until it engages. Push firmly until it clicks. Guidelines for Installing Hard Drives in Drive Enclosures 25
