Preface vi Storage Center System Setup Guide
1 Getting Started Pre-installation Documents All hardware must be installed and cabled before you begin the setup and software installation process. If server connectivity is through Fibre Channel (FC), the FC switches must be configured and zoned before the controller/s are set up.
Getting Started System Power Up Power on the system by pressing the power switches in the following order. 1 Power up each enclosure. Simultaneously press the two power switches on the rear of each enclosure. 2 Wait several minutes until the drives spin up. 3 After all drives in the enclosure spin up, power up each controller by pressing the power button on the front of the enclosure. Note Always power up disk drive enclosures before powering up the controllers.
2 Setting Up the Storage Center Setting Up a Controller Once hardware has been racked and cabled and any FC switches that provide server connectivity have been configured and zoned, you configure and identify a controller. Configuring a controller includes the following tasks: • Connect to a Controller on page 3 • Reset Hardware and System Serial Numbers on page 4 • Set IP Addresses on page 5 If you have a dual-controller system, you will configure both controllers using the serial connection.
Setting Up the Storage Center Setting Value Parity None Data Bits 8 Stop Bits 1 Flow Control Hardware or default Note You should also enable logging as the logs will be helpful if Copilot support is needed. 4 Press Enter several times to initiate the connection. The terminal echoes back to indicate that connectivity has been established. If the prompt is not displayed, verify the communications settings or cabling.
Setting Up a Controller Set IP Addresses Storage Center controllers use static IP addresses. • eth0 supports system login and access for the software. It is used to send email, alerts, SNMP traps, and phone home data. • eth1 is used for dedicated Inter-Process Communication (IPC) between controllers in a clustered-controller system. There is no default gateway for eth1. Note There is rarely a need to change the eth1 address as it is only used for IPC between controllers.
Setting Up the Storage Center Configuring a System via the Startup Wizard After establishing a connection to Controller 1, use the Storage Center Startup Wizard for the remainder of the setup.

3 Virtual Storage and Virtual Ports About Virtual Storage 50 About Virtual Ports 51 49
Virtual Storage and Virtual Ports About Virtual Storage Storage Center accelerates data access by spreading read/write operations across all disk drives, so multiple requests are processed in parallel. This is known as storage virtualization, where the physical drives are abstracted from the logical view of the data that the end user sees. Storage Center removes the limitations of physical drives by aggregating them into logical, virtual volumes.
About Virtual Ports About Virtual Ports Storage Center 5.0 introduced the Virtual Ports feature that enables a Storage Center to dramatically expand the number of available Front End ports. In contrast to the Primary/ Reserved physical front end port designations, Virtual Ports allow all Front End ports to be used as Primary thereby eliminating the need for Reserved ports. All ports within a network or fabric are Primary and can read and write IO.
Virtual Storage and Virtual Ports Virtual Port Mode By default, a single virtual port resides on each Front End Physical port. If a port or controller fails, Storage Center moves the virtual port to another Physical port within the Fault Domain. By definition, Physical ports cannot be moved. Because volumes are mapped to servers via virtual ports, failover of a Virtual port to a second Physical port ensures the integrity of data via the Fault Domain.
Glossary A Assigned Disks Same as Managed Disks. Physical disks that are identified by Storage Center and to which data can be written. Assigned disks use metadata to track information about volumes on the disk and other assigned disks managed by the controller. B Back End The component in the Storage Center SAN flow of data writes (server to switch to controller to disks) that receive data writes. In general, drives in enclosures are the back end of the controller.
Glossary Controller Provides disk aggregation (RAID), I/O routing, error detection, and data recovery. Provides the intelligence for the entire Storage Center subsystem. A Storage Center system contains at least one controller. Copilot Services Combination of centralized support, product education and sales resources that proactively monitor Storage Center and recommend corrective actions to improve performance and availability of the system.
F FC See Fibre Channel FCP Fibre Channel protocol for SCSI FTP File Transfer Protocol. Program used to transfer files from another computer. Fabric A combination of interconnected switches that act as a unified routing infrastructure. It allows multiple connections among devices on a SAN and lets new devices enter unobtrusively. A Fibre Channel (or iSCSI) topology with at least one switch present on the network. Fault Domain A fault domain defines the association between front end ports to one another.
Glossary HBA Type In the Storage Center, there are two HBA types: Fibre Channel and iSCSI. Hot Spare A hot spare disk is a backup disk. In the event that an active disk within the array fails, the controller makes the hot spare part of the active array and rebuilds data on the fly. Host Bus Adapter See HBA I IO Input/output.
NFS Network File System NIC Network Interface Card P Pagepool A pool of storage from which volumes are stored. See Storage Type on page 60. Physical Port The physical connection point on servers, switches, Storage Center controller, and disk drive enclosures that is used to connect to other devices in the system. R RAID (Redundant Array of Independent Disks) A way of encoding data over multiple physical disks to ensure that if a hard disk fails a redundant copy of the data can be accessed.
Glossary RAID 10-DM RAID 10 Dual Mirror provides maximum protection for storage. Data is written simultaneously to three separate disks. All three disks return a write acknowledgement. RAID 10 protects against data loss when any 2 disks fail. Redundancy The duplication of information or hardware equipment components to ensure that if a primary resource fails, a secondary resource can take over its function. Storage Center provides redundancy for each component so that there is no single point of failure.
Server Dedicated computers that handle network tasks. Servers employ load balancing and caching appliances at the front end to give users the illusion that they are accessing a single server instead of smaller servers grouped together. Servers connect to the Storage Center SAN to provide enterprise-level storage capacity and manageability. SMTP Simple Mail Transfer Protocol (SMTP) defines a message format and forwarding procedure to enable messages to be sent between hosts on the Internet.
Glossary Storage Profile A collection of rules that identify RAID level and drive types (tiers) on which data is stored. All volumes are attached to a Storage Profile. Storage Type Pool of storage from which volumes are created. Storage Center is most efficient when all disks are combined into one pool of storage. Data Progression can then store data with maximum efficiency. In some circumstances, you can create additional storage types based on redundancy and data page size.
Volume A volume is a discrete area of storage striped to multiple hard disks. Volume Type Specifies the volume type: Dynamic, Replay Enabled, or Replication. W WWN World Wide Name. WWPN World Wide Port Name a world-wide, unique 8-character name that defines an FC port.
