The MSA500 G2, shown in Figure 12-3, is a 4U, Ultra320 SCSI storage enclosure. It supports up to 14 HP Universal disk drives and is expandable with an in-place upgrade to the MSA1000. The MSA500 G2 system adds support for four-node clusters and a combined cluster and storage-sharing environment. Figure 12-3. StorageWorks MSA500 enclosure.Providing high data availability at SCSI economics, the MSA500 G2 offers superior data protection and increased uptime with redundant controllers, power supplies and fans, and the Smart Array Multipath software option to provide multiple I/O paths to the same logical volume. Because the MSA500 G2 is SCSI based, there are no Fibre Channel infrastructure requirements such as hubs, switches, and cables, allowing for significantly lower initial investment when compared to Fibre Channel SANs. Armed with DAS-to-SAN (DtS) technology, the MSA500 G2 adaptive infrastructure permits seamless conversion from SCSI protocol to the Fibre Channel-based HP StorageWorks MSA1000. Key MSA500 G2 features include the following:
