book.book Page 9 Sunday, September 11, 2011 10:24 PM Unconfigured capacity comprises of physical disks not already assigned to a disk group. When a virtual disk is created using unconfigured capacity, a disk group is automatically created. If the only virtual disk in a disk group is deleted, the disk group is also deleted. Free capacity is space in a disk group that is not assigned to any virtual disk. Data is written to the physical disks in the storage array using RAID technology. RAID

book.book Page 12 Sunday, September 11, 2011 10:24 PM Connecting the Storage Array The storage array is connected to a host using two hot-swappable RAID controller modules. The RAID controller modules are identified as RAID controller module 0 and RAID controller module 1. Each RAID controller module has four iSCSI In port connectors that provide Ethernet connections to the host server or switches. Each RAID controller module also contains an Ethernet management port and a SAS Out port.

book.book Page 13 Sunday, September 11, 2011 10:24 PM Direct-Attached Configurations You can connect the Ethernet ports of the host servers directly to the storage array RAID controller module iSCSI ports. Single Path Data Configurations With a single path configuration, a group of heterogeneous hosts can be connected to the storage array through a single physical Ethernet port. Since there is only one port, there is no redundancy, although each iSCSI portal supports multiple connections.

book.book Page 17 Sunday, September 11, 2011 10:24 PM Dual-Path Data Configuration In Figure 2-4, up to four servers are directly attached to the RAID controller modules. If the host server has a second Ethernet connection to the array, it can be attached to the iSCSI ports on the array's second controller. This configuration provides improved availability by allowing two separate physical paths for each host, which ensures full redundancy if one of the paths fail. In Figure 2-5, up to f

book.book Page 20 Sunday, September 11, 2011 10:24 PM Network-Attached Configurations You can also cable the host servers to the RAID controller module iSCSI ports through industry-standard 1GB Ethernet switches. An iSCSI configuration that uses Ethernet switches is frequently referred to as an IP SAN. By using an IP SAN, the PowerVault MD3200i series storage array can support up to 64 hosts simultaneously. This configuration supports either single- or dual-path data configurations and e
