RAID is a way to virtualize multiple, independent hard-disk drives into one or more arrays to improve performance, capacity, and reliability (availability).
Configuring RAID 5 using Server Administrator. Introduction: RAID is a way to virtualize multiple, independent hard-disk drives s into one or more arrays to improve performance, capacity, and reliability (availability). RAID Level 5 (Striping with Distributed Parity). RAID 5 provides data redundancy by using data striping in combination with parity information.
Rather than dedicating a physical disk to parity, the parity information is striped across all physical disk drives in the disk group. This video helps you to understand Configuring RAID 5 using Server Administrator on Citrix XenServer 6.2. Prerequisites: System with supported Citrix XenServer operating system. Internet connectivity. Minimum of 3 Physical Disks.
Root user login details. Login. Actions: Launch Server Administrator. The “Login” page is displayed. Click “Manage Remote Node”. Type the following details: “Hostname/IP Address: <PORT NUM>”. “Username”. “Password”. Select “Ignore certificate warnings”. Click “Submit”. To display the availability of physical disks in the system, go to “System > Storage > PERC H810 Adapter (PCI Slot 2) > Connector 1 (RAID) > Physical Disks”.
4: Create Virtual Disks. The “Physical Disks on Controller PERC H810 Adapter” page is displayed. To create a virtual disk, click “Virtual Disks”. Click “Go to the Create Virtual Disk Wizard”. The “Create Virtual Disk Wizard (Step 1) - PERC H810 Adapter” page is displayed. Under “Select RAID Level”, select the “Advanced Wizard” option. From the “Create Encrypt Virtual Disk” drop-down list, select “No”. From the “RAID Level” drop-down list, select “RAID-5" and click “Continue”.
The “Create Virtual Disk Advanced Wizard (Step 2 of 3) - PERC810 Adapter” page is displayed. Under “Connector 1”, select the required physical disks. Note: A minimum of 3 and a maximum of 32 physical disks are allowed for a RAID-5 configuration. Click “Continue”. The “Create Virtual Disk Advanced Wizard (Step 3 of 3) - PERC H810 Adapter” page is displayed. You can modify the data in the following fields: Name, Size, Stripe Element Size, Read Policy, Write Policy, Disk Cache Policy. Under “Assign Dedicated Hot Spare”, select a physical disk.
Note: When a physical disk stops functioning, you can assign a backup disk to take over the tasks. The backup disk must be of greater or equal memory capacity of the physical disks displayed under “Selected Physical Disks”. Click “Finish”. The “Message from webpage” dialog box is displayed. Click “OK”. The “Virtual Disk(s) on Controller PERC H180 Adapter” page is displayed. The virtual disk is created. Repeat the same process to add multiple virtual disks.
To view the added physical disks, click “R5”. The “Physical Disks included in Virtual Disk” page is displayed. For more information, visit: dell.com/openmanagemanuals. www.delltechcenter.com/omsa.
