SAN fabric management
SAN fabric management refers to controlling the network traffic with the SAN. More specifically, it pertains to control and management of device communication or access within the SAN, such as switch zoning or LUN-level Selective Storage Presentation (SSP). It also includes managing SAN interconnect components, individually and collectively, throughout the fabric.
SAN storage management
Storage management allows control of the specific storage system configuration including redundant paths, storagesets (LUNS), RAID levels, and platform-specific SAN interface parameters.
SAN data management
SAN data management applications help ensure that data is available and accessible. The data being stored on the SAN is part of the assets of a company. It is imperative to keep this data available to system applications with minimal, if any, downtime. Techniques such as cloning, snapshots, data replication, and backups protect the data from disasters.

SAN usage and monitoring
SAN and storage usage and monitoring applications are necessary to provide SAN event notification and failure information for service before SAN anomalies can adversely impact the enterprise. They may also provide reporting and billing information for determining the amount of storage and quality of service delivered.

SAN fabric management tools
Supported management methods include:
+ SNMP
+ Web-based management tools launched through Network View
+ Telnet command subset by means of the front panel display of the switch (Fibre Channel SAN Switch 16 only)
SAN storage management tools

Selective Storage Presentation (SSP) provides a way to control SAN access at the storageset or LUN level. SSP allows the storagesets of each server or HBA to be presented exclusively to servers that are allowed access.
SSP allows the setting of host modes and LUN offsets for each HBA connected to the storage system. The host mode is specially tailored to the storage communication techniques of the operating system type. The LUN offset feature of SSP allows higher numbered LUNs in a storage array to be presented in a range required by specific operating systems.
SSP also provides a way to track the numerous Fibre Channel HBAs within servers attached to a SAN by identifying each by name and WWN.
The HP StorageWorks Array Configuration Utility (ACU) (for Smart Array products, StorageWorks RAID Array 4100/4000 systems, and MSA1000 systems) makes it easy to configure and expand your disk drive arrays. Software features and functionality:
+ Selective Storage Presentation — Allows RA4100 and MSA1000 array sets to be partitioned to multiple servers for SAN access
+ Online RAID Level Migration — Allows for online post-configuration change to RAID level without destroying data or volume information.
+ Online Capacity Expansion — Lets you add storage to an operational RA4100 or MSA1000, reducing expensive server downtime.
+ Online Volume Extension — Allows for the capacity growth of existing logical volumes.
+ Global Online Spare — Reduces the risk of data loss by facilitating automatic rebuilds after a drive failure.
+ Logical Drive Capacity Extension — Allows you to increase the size of existing logical drives online under Windows NT and offline for other operating systems.
+ Pre-Failure Warranty — Supports drives installed in an RA4100 or an MSA1000 and monitored under HP Insight Manager are supported by a Pre-Failure (replacement) Warranty.
HP Secure Path provides continuous data access for HP RAID storage systems accessed by operating systems. When combined with the inherent fault-tolerant features of a RAID array, this configuration effectively eliminates single points of failure in the storage system.
When an HBA, cable, or controller in a path fails, the failure is detected and I/O is automatically rerouted to the functioning, alternate path. This process, called failover, requires no resource downtime and ensures high availability of data.
SAN data management tools
HP StorageWorks Business Copy: Business Copy (BC) is web-based application software that manages controller-based clone and snapshot operations. Cloning is a mirroring copy function that allows you to create an exact copy of a LUN; snapshot provides an instantaneous point-in-time copy function.
BC improves availability by minimizing the application downtime required for system backups and data migration activities. BC automates the creation of command files that control the cloning or snapshot operation. BC also allows you to mount the clone or snapshot on a second host on the same controller.
The HP OpenView Storage Virtual Replicator (VR) simplifies storage management: Virtual Replicator provides the ability to create instant, virtual snapshots of production data. A snapshot, which looks exactly like the original disk from which it was copied, takes seconds to create and allows customers to back up and restore data with minimal impact to users and applications. Customers can schedule automated snapshot backups using integrated policy-based scheduling and scripting features.
+ Virtualization — Allows companies to respond quickly to rapidly changing storage capacity requirements. With storage virtualization, multiple storage arrays can be grouped into a pool of disk space for individual or clustered systems to use. Multiple high-capacity virtual disks, up to 2TB in size, can be created from a pool for users and their applications. System administrators can tailor disk space to specific requirements for maximum utilization of storage resources.
+ Online Volume Growth — Enables easy, nondisruptive growth for Windows 2K3 storage volumes with no downtime. System administrators to grow an existing volume on a Virtual Replicator virtual disk and also on a Windows 2K3 basic disk. The system will remain online, and the data on the volume will remain intact.
+ Snapshots — Enable the instant creation of virtual replicas of production data without the requirement of a physical copy. Snapshots function identically to physical disks, with both read and write capability. Snapshots can remain online for restore operations, testing, and data mining.
+ Management — Simplifies management of arrays through easy-to-use interfaces using the Microsoft Management Console or a command line. Interactive wizards are available to guide the administrator through all management tasks and create automatic schedules of operations.
+ Virtual Replicator provides server-based virtualization, Virtual replicator is clusteraware to ensure business continuance.
Continuous Access EVA is a Fibre Channel storage controller-based data replication (remote mirroring) solution to support disaster tolerance requirements. Continuous Access EVA works with the HP StorageWorks Enterprise Virtual Array storage system, which contains the HSV virtualized RAID controller. The HSV controller and the Virtual Controller Software (VCS) 3.0 and 3.01 enhance the virtualization with remote replication technology.
Continuous Access EVA copies data online and in real time via synchronous (and in Version 3.01 asynchronous) replication to a remote EVA through a local or extended storage area network (SAN). Additionally, data replication can be bidirectional, meaning that a storage array can be both a source and a destination. A single EVA may have a replication relationship with up to two other arrays, using different DR groups for each relationship. A particular LUN can be replicated in only one direction between the two storage arrays. Write I/O is sent to the source and then replicated by Continuous Access to the destination. Properly configured, Continuous Access EVA can be a complete disaster-tolerant storage solution that guarantees data integrity in the event of a storage system or site failure.
The HSG80 Data Replication Manager (DRM) Software is the software component of the HSG80 array controller used in switched fabric environments for remote data replication. Data Replication Manager Software is a storage-based disaster tolerance and workload migration solution that provides the ability to copy data, in real time, to a remote location, up to 100 km away using direct Fibre Channel or further using either Fibre Channel over ATM or Fibre Channel over IP links:
