• Minimum display setting of 800 x 600 pixels with 256 colors (1024 x 768 pixels with 16-bit color recommended) Introduction to Storage Arrays A storage array includes various hardware components, such as physical disks, RAID controller modules, fans, and power supplies, gathered into enclosures. An enclosure containing physical disks accessed through RAID controller modules is called a RAID enclosure. One or more hosts attached to the array can access the data on the storage array.
You can provide an additional layer of data redundancy by creating hot spares in a disk group that has a RAID level other than 0. Hot spares can automatically replace physical disks marked as Failed.
Introduction
Hardware Installation This chapter provides guidelines for planning the physical configuration of your Dell™ PowerVault™ MD3000 storage array and for connecting one or more hosts to the array. For complete information on hardware configuration, see the Dell PowerVault MD3000 Hardware Owner’s Manual. Storage Configuration Planning Consider the following items before installing your storage array: • Evaluate data storage needs and administrative requirements. • Calculate availability requirements.
Each RAID controller module has at least one SAS In port connector that provides the direct connection to the host or node. A second SAS In port connector is available on the optional dual-port RAID controller. SAS In port connectors are labeled In-0 and, if using the optional controller, In-1(see the PowerVault MD3000 Hardware Owner’s Manual for more information). Each MD3000 RAID controller module also contains a SAS Out port connector.
Single SAS In Port Configurations Figure 2-1 through Figure 2-5 show supported nonredundant and redundant cabling configurations to MD3000 RAID controller modules with a single SAS In port connector. Each diagram shows the maximum number of optional expansion enclosures attached. Figure 2-1 through Figure 2-3 show one and two hosts, each connected to only one RAID controller module that is subsequently expanded to two more storage enclosures.

Dual SAS In Port Configurations Figure 2-6 through Figure 2-12 show supported nonredundant and redundant cabling configurations to MD3000 RAID controller modules with two SAS In port connectors. Each diagram shows the maximum number of optional expansion enclosures attached. Figure 2-6 shows how one, two, three, and four hosts can each be connected to a RAID controller module nonredundantly. The RAID controller module is subsequently expanded to two more storage enclosures.
Figure 2-7 through Figure 2-10 show redundant, high-availability cabling configurations for one and two hosts. If any one path fails, at least one HBA is still connected to one RAID controller.
