HP StorageWorks Array Controller Software (ACS) v8.8-2

Overview

HP StorageWorks Array Controller Software (ACS) v8.8-2

The HP StorageWorks Array Controller Software (ACS) provides storage controller capability for the HP StorageWorks HSG80 and HSG60 Storage Array Controllers. The HSG80 controller can be deployed into the Modular Array (MA) 8000, Enterprise Modular Array (EMA) 12000, Enterprise Modular Array (EMA) 16000, RAID Array (RA) 8000, and Enterprise Storage Array (ESA) 12000 storage systems and the HSG60 controller is deployed into a Modular Array (MA) 6000. ACS is supplied to the array on a PCMCIA card that is inserted into a receptacle on the face of the HSGx0 controller. Each controller must receive a card for the array to be operable. The same version (v8.8-2 for instance) and the same variant (L, G, F, S, or P) must be in each controller comprising a redundant pair.

What's New
ACS V8.8-2 improves serviceability and availability of the HSG80 and HSG60 storage array systems.

The following sections describe these capabilities:

Microsoft Cluster Server (MSCS)	MSCS enables the hosts to share the storage system through the Fibre Channel bus with Windows® NT® cluster software. Should a failure occur on one host, the storage I/O is re-routed to the functioning host.

Support for up to 84 devices per storage system	HSG80 controllers using ACS v8.8 provide support for up to 14 devices per device port and 84 devices per dual-redundant storage system, with a maximum of 28 devices in the HSG60 controller (ma6000).

Dual Redundant Controller Operation	HSG60 and HSG80 controllers using ACS can operate as a redundant pair of controllers when configured identically and running identical software versions, including patches, and connected in the same backplane. ACS provides facilities to detect controller failure and perform automatic controller failover.

Testing and Diagnosis of the HSG80 Array Controller	ACS software internal diagnostics execute automatically whenever controller power is turned on, whenever the array controller is reset and periodically during use. LEDs on the controller's front bezel provide diagnostic information upon controller failure. A local serial connection asynchronous I/O port is provided for configuration and diagnosis.

Transparent Controller Failover	ACS supports the connection of two host Fibre Channel buses to a dual-redundant HSG60 or HSG80 controller pair. This configuration provides active ports on two separate paths. The use of transparent controller failover is independent of the host operating system. The controller pair provides two active and two standby ports. If the active port, on one controller, becomes non-operational the standby port, on the other controller, will be presented to the host without host intervention.

Multiple Bus Controller Failover	In multiple bus failover, the controller can present units to the host on all four ports. Software on the host is responsible for switching to another path if it can't access the units on the primary path.

Asynchronous Disk Swap (Hot Swap)	ACS supports asynchronous disk swaps, also known as Disk Hot Swap. This is defined as disk removal and insertion without regard to a quiescent device bus. Disks can be removed or inserted at any time with some restrictions. Restrictions are noted in the user documentation.

ACS System Management Services	ACS software provides the following storage system management services:
	Alteration of Storage System Parameters	ACS includes a command line interface (CLI) that allows a system manager to display and manipulate controller parameters and device configuration information as required. The CLI utility provides type ahead, recall and editing features. Any of the last four commands entered may be recalled and edited
	Environmental Monitor Unit (EMU)	ACS monitors data on the state of the HSG80 controller and storage system. This data can be reported via CLI and is reported in Environmental Monitor Unit (EMU) LEDs and in some cases activate an audible alarm. (RA/ESA models)

Mirrored Write-Back Cache Capability

The battery or UPS backed write-back cache capability provides the following functions:

Stores data to be written temporarily in the controller's write-back cache and if the mirrored option is set, the write-back data is mirrored in the redundant controllers cache for fault tolerance. The controller then informs the host that the write request is complete. This allows the host to continue working without waiting for data to be written to disk media.
Writes the data stored in cache to the disk media based on a least-recently-used cache flushing policy or when a device has been inactive for a defined period of time.
Consolidates contiguously located data blocks from multiple host write requests into a single device request to reduce average latency.
On recovery from a single cache failure or power outage, the controller detects that unwritten data still exists in cache and writes it to disk media before enabling normal controller operations.

Read Ahead Cache Capability	If sequential read requests are received from the host, Read Ahead Cache allows the controller to anticipate subsequent read requests and prefetch the next data blocks. This provides read performance optimization.

Disk Mirroring Capability (RAID 1)

The disk mirroring capability provides the following functions:

Real-time maintenance of up to six identical copies of data on mirrorsets of separate disks attached to a single HS array controller.
Protects data against disk failure by replicating all data on each member of the mirrorset. Disk mirroring offers extremely high data reliability.
Striping of mirrorsets, for high-performance access to large amounts of highly available data.
Captures a designated spare (if one exists) in the event of a mirrorset member disk failure and reconstructs the data of the failed member disk onto it.
The ability to increase or decrease the number of members in a mirrorset as requirements change.
Flexible policy options for determining both how read requests are satisfied and the speed of copying when a new member is being added.
ACS disk mirroring can utilize the UNMIRROR command to change mirrorsets back to single-disk units.

Disk Striping (RAID 0 & 0+1)	ACS treats sets of disk drives as stripesets (2 to 24 members up to a maximum StorageSet size of 1.024 TB) for improved I/O performance through load distribution. A stripeset appears to the operating system as a single virtual disk drive. Striping of mirrorsets can be used for high performance access to large amounts of highly available data.

RAID Capability
(RAID 3/5)

The RAID capability provides the following functions:

Manages up to 20 sets of between 3 and 14 disks as RAIDsets (up to a maximum RAIDset size of 1.024 TB). A RAIDset is viewed by the host as a single virtual disk. RAIDsets can tolerate the failure of a single member disk without loss of ability to deliver data to hosts.
Dynamically adjusts between RAID Level 5 and RAID Level 3-like data protection algorithms depending on instantaneous workload.
Maintains consistency of data and parity across all member disks in a RAIDset. This includes recovery from media errors.
Detects failure of a single RAIDset member disk and invokes data regeneration algorithms to provide continued data availability to hosts.
Captures a designated spare (if one exists) in the event of a member disk failure and reconstructs the data and parity of the failed member disk onto it. Settable chunksize to match RAIDset performance attributes to host I/O profile.
For information regarding default chunksize, refer to the HSG80 Array Controller ACS v8.8 Installation and Configuration Guide and the HSG80 Array Controller ACS v8.8 CLI Reference Guide.

StorageSet Expansion	StorageSet Expansion allows for the joining of two of the same kind of storage container. StorageSet Expansion can be utilized to easily expand a storage container by concatenating RAIDsets, Stripesets or individual disks thereby forming a larger virtual disk, which is presented as a single unit. The joining of RAIDsets provides the user with the same redundancy and reliability as the individual sets without having to back-up and restore the data. StorageSet Expansion of RAID 3/5 sets provides the same functional capabilities as the original RAID 3/5 sets. In addition to the easy creation of a larger RAIDset, expanded RAIDsets can tolerate the failure of two member disks (a single member out of each original RAIDset) without loss of ability to deliver data to hosts. See the solution documentation for configuration information and restrictions.

Selective Storage Presentation	Selective Storage presentation is a feature of the HSG60 and HSG80 controllers that enables the user to control the allocation of storage space and shared access to storage across multiple hosts. This is also known as "Restricting Host Access". In a subsystem that is attached to more than one host or if the hosts have more than one adapter, it is possible to reserve certain units for the exclusive use of certain host connections.

Disk Partitioning	ACS allows partitioning of disk drives or storage sets for improved device management. A partition appears to the operating system as a single virtual disk. Up to 8 partitions may be created per storage set or disk drive. Disk partitioning is supported in both transparent and multiple bus failover. See the operating system configuration manual for any restrictions. NOTE: Disk partitioning is not supported in DRM Remote Copy Sets.

Support for up to 14 drives per SCSI bus	ACS supports up to 14 devices per SCSI bus. In a maximum single six bus configuration on an HSG80 controller, the total drives supported is 84. In the HSG60 controller, the maximum number of total drives supported is 28.

Support for up to 96 host connections	ACS supports a maximum of 96 host connections to a single array controller. Host port connection support is operating system specific. Please consult the ACS v8.8 Installation and Configuration Guide and the Heterogeneous Open SAN Design Guide for details.

Snapshot Capability (Available only in ACS v8.8S and P)

ACS with Snapshot capability provides a quick and efficient way to make a point-in-time copy of a storage container's data. Snapshot freezes a map of the container's data, which can be separated and used for backup or testing and manipulation without impacting the original data. After the Snapshot, the original data can continue to be updated and utilized while the Snapshot copy remains unchanged.

When the need for the duplicate copy of data is ended a new snap of a different storage container can be made and the process repeated. Snapshot eliminates much of the overhead associated with mirroring and cloning as the snap is dissolved without having to re-merge the data. Refer to the solution documentation for configuration information and restrictions.

ACS 8.8P Data Replication Manager Features

Additional Capabilities

In addition to capabilities listed above, ACS 8.8P Data Replication Manager software (DRM) includes the following additional capabilities:

Data Replication from one Storage System to another
Synchronous and Asynchronous Copy Operation
Write History Logging (WHL)
Fast failback, for planned failover and failback activity
Normal or Failsafe modes of operation
Cluster Support

The following describes these additional capabilities:

Data Replication from One Storage System to Another	Data Replication Manager Software provides 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 or further using Fibre Channel over ATM links. This is done without any host involvement. The HSG80 dual host port design, when used in DRM configurations, allows for the use of the switched Fibre Channel topology to accomplish long distance mirroring. This is done through the use of an initiator and target sharing a Fibre Channel switch connected by a switched Fibre Channel fabric. Data is copied from a local controller directly to another controller at a remote location. This capability provides customers with the ability to maintain the same data at a remote location providing Disaster Tolerance protection.

Synchronous and Asynchronous Copy Operation	In synchronous operation mode, data is simultaneously written to the cache of the initiator subsystem and the cache of the target subsystems. The I/O completion status is not sent to the host until all members of the remote copy set are updated. In asynchronous operation mode, the write operation is reported to the host as complete before the data is written to the remote unit of the remote copy set. Asynchronous mode can provide improved response time, but the data on all members of the remote copy set will not be an exact copy of the latest data at the local side.

Write History Logging (WHL)	Write History Logging provides a mechanism to log writes to a target controller while there is a link failure. Once configured for WHL, if the links go down, the incoming "writes", are written to the log disk. Once the links are restored, write commands are issued from the log (referred to as "mini-merged") to the target to resynchronize the data. While this process is occurring, any new write operations are appended to the log until the log is emptied. The write operations are issued in the same order in which they were acknowledged to the host. The Write History Log size is customer settable. Once the log container size is exceeded the customer would need to re-merge to synchronize the data at the target site. By utilizing Write History Logging the customer can substantially reduce resynchronization times by reducing/eliminating the need for a full merge copy of data to the target once the links are restored.

Fast Failback	Fast failback provides support for manual site failover and failback activities. Fast failback utilizes Write History Logging to provide mini-merge of the target "write" data logged during the failover period: Mini-merge functionality allows the controller to update only the data that has changed on a re-joined Remote Copy Set (RCS). This may greatly reduce controller overhead and the time required to re-merge RCS during or preparing for a fast failback. Fast failback is supported in Synchronous controller operation. The log unit must be configured to support this feature See the user documentation for configuration support and restrictions.

Normal or Failsafe Modes of Operation	Normal mode can be enabled by the user to process additional I/Os by the host at the initiator site even if the target site has become inaccessible (normal mode enables continuous initiator host processing). Failsafe mode can be enabled by the user to stall any I/O, whenever the target is inaccessible. The remote copy set is considered Failsafe Locked under this condition, and goes into the inoperative (offline) state. Failsafe mode provides the ability to keep the initiator and target consistent.

Cluster Support	Hosts per site can be configured in a clustered environment using HSG80 Controllers with v8.8P. This enables the hosts to share the storage subsystem utilizing the Fibre Channel bus. Should a failure occur on one host, the storage I/O can be accessed by another functioning host within the cluster. Refer to the user documentation for configuration support and restrictions.

Features	Business Copy UI MA/EMA is a product for MA/EMA customers with ACS F, P, and S who want the graphical interface to manage creation of clones or snapshots. The types of Business Continuance Volumes supported on the MA/EMA are as follows:
	Clones	A clone is a complete copy of the data on a LUN. Its two primary advantages are that it can completely offload processing from the application volumes and since it is a complete copy, provide a form of disaster tolerance for the volumes. The Array Controller Software will allow multiple copies to exist simultaneously.
	Snapshots	This type of copy is a virtual copy of the data. Its primary advantage is that it can be made in seconds, which provides the user maximum flexibility for use. Another advantage is that since there is no normalization time, as with clone creation, snapshots only need the necessary disk resources for a minimum period of time. A set amount of capacity equal to the original volume is reserved, however data is not written until necessary. As the data changes in the original source volume, the corresponding snapshot copy is also updated.
	Business Copy UI MA/EMA Requirements	ACS Version v8.6 / 8.7/8.8 F (clone capability only) ACS Version v8.6 / 8.7/8.8 S (clone and snapshot capability), ACS v8.6 / 8.7/8.8 P (remote mirroring with clone and snapshot capabilities)
		To use the clone or snapshot method in a Business Copy job, there must be free disk resources on the HP StorageWorks system that equal or exceed the disk capacity of the source units being replicated in the job. To be able to use snapshots in Business Copy jobs, you must have the snapshot version of the ACS firmware installed.
	Transition Information for Existing EVM Customers to Business Copy UI MA/EMA	The Business Copy UI for MA/EMA can be thought of as the next version of the EVM product. Customers with Software Subscription Service contracts for EVM automatically receive the new management interface and host agent CD's. The Business Copy UI for MA/EMA can be downloaded for free from hp.com Same capabilities as existing EVM with new features for management UI.
