Manual Resizing Of CacheCade Virtual Disks In operating system management applications, a manual resizing of a CacheCade virtual disk occurs due to the addition or removal of drives. Reboot is not necessary. • Any number of SSDs can be added to a CacheCade virtual disk. • There is no SAS and SATA mixing allowed within a CacheCade virtual disk, so SATA SSDs cannot be added to a SAS CacheCade virtual disk and vice versa. • HDDs cannot be added to a CacheCade virtual disk. NOTE icon NOTE: Capacity of drives added to a CacheCade volume must be equal to or greater than the smallest contributing drive in the virtual disk. The manual resizing of a CacheCade virtual disk cannot be initiated in the BIOS Configuration Utility. It can only be initiated in the OpenManage storage management application. 7 Security Key And RAID Management NOTE icon NOTE: PERC H310 does not support any security implementations. Security Key Implementation The Dell PowerEdge RAID Controller (PERC) H710, H710P, and H810 cards support Self-Encrypting Disks (SED) for protection of data against loss or theft of SEDs. Protection is achieved by the use of encryption technology on the drives. There is one security key per controller. You can manage the security key under Local Key Management (LKM). The key can be escrowed in to a file using Dell OpenManage. The security key is used by the controller to lock and unlock access to encryption-capable physical disks. In order to take advantage of this feature, you must: 1. Have SEDs in your system. 2. Create (LKM) a security key. Security Key Management In The BIOS Configuration Utility The Dell OpenManage storage management application and the BIOS Configuration Utility () of the controller allow security keys to be created and managed as well as create secured virtual disks. The following section describes the menu options specific to security key management and provide detailed instructions to perform the configuration tasks. The contents of the following section apply to the BIOS Configuration Utility (). For more information on the management applications, see the topic Management Applications For PERC Cards. • The Virtual Disk Management screen, VD Mgmt, is the first screen that is displayed when you access a RAID controller from the main menu screen on the BIOS Configuration Utility (). The following are security- related actions you can perform through the virtual disk management menu: – Security Key Management—Creates, changes, or deletes the security settings on a controller. – Secure Disk Group—Secures all Virtual Disks in Disk Group. • The Physical Disk Management screen, PD Mgmt, displays physical disk information and action menus. The following are security-related actions you can perform through the physical disk management menu: – Instant Secure Erase—Permanently erases all data on an encryption-capable physical disk and resets the security attributes. For more information on the Physical Disk Management screen and Virtual Disk Management screen, see the topics Physical Disk Management (PD Mgmt) and Virtual Disk Management respectively. Local Key Management (LKM) You can use LKM to generate the key ID and the passphrase required to secure the virtual disk. You can secure virtual disks, change security keys and manage secured foreign configurations using this security mode.NOTE icon NOTE: Under LKM, you are prompted for a passphrase when you create the key. Creating A Security Key Perform the following steps to create a security key on the controller:NOTE icon NOTE: There is no passphrase backup option when you create a security key; you need to remember your passphrase. 1. During the host system boot up, press when the BIOS screen is displayed. The Virtual Disk Management screen is displayed. If there is more than one controller, the main menu screen is displayed. 2. Select a controller, and press . The Virtual Disk Management screen is displayed for the selected controller. 3. Use the arrow keys to highlight Security Key Management. 4. Press to display the actions you can perform. 5. Select Create Key and press . The Create Security Key screen is displayed. The cursor is at the Security Key Identifier. 6. Enter an identifier for your security key. NOTE icon NOTE: The Security Key Identifier is a user supplied clear text label used to associate the correct security key with the controller. 7. Press to enter a passphrase. CAUTION icon CAUTION: If you lose or forget your passphrase, the data in your virtual disk is inaccessible. 8. Press and select OK to accept the settings and to exit the window. Select Cancel to exit if you do not want to create a security key on the controller. Changing The Security Key NOTE icon NOTE: Change Key is active if there is a security key present on the controller. Perform the following steps when changing the security key on the controller: 1. During host system bootup, press Questo manuale è adatto anche per i modelli : Computer - H310 (1.14 mb) Computer - H710 (1.14 mb) Computer - H710P (1.14 mb)
