HP StorageWorks Secure

Path

HP StorageWorks Secure Path is a family of high availability multi-pathing software products providing continuous

data access from the HP RAID Array to host servers running the Windows Server 2003, Windows 2000, Windows

NT, Linux and NetWare operating systems.

Redundant hardware, advanced RAID technology and Secure Path's automated failover capability are used to

enhance fault tolerance and availability. Secure Path effectively eliminates controllers, disk drives, interconnect

hardware and host bus adapters as single points of failure in the storage subsystem.

The attachment of non-Secure Path (single HBA) servers to an MSA1000 with dual controllers that has servers with

Secure Path (dual HBA) attached is supported where the operating systems are Windows or NetWare. Users must

realize that in event of a controller fail-over (failure of active controller) the single path servers will lose access to

their data on the MSA1000.

NEW

- Secure Path can now support up to an 8-node cluster in Windows Server 2003.

NOTE:

If Secure Path for Linux is used on any node or cluster attached to an MSA1000, all nodes must also have

Secure Path installed, regardless of operating systems.

NOTE:

MSA1000 clustering

Clustering is rapidly gaining in popularity as users desire a high level of data availability. Many of the old cluster

restrictions that were the product of both hardware and operating systems have been overcome. While there still

remain configuration limits, the result is a new high degree of flexibility both in number of clusters, mixing clusters

with single nodes, and the integration of dissimilar operating systems.

For example you may mix three Microsoft (Windows Server 2003, Windows 2000, or Windows NT) clusters and

other individual servers, even doing so in a heterogeneous server operating system environment. Windows Server

2003 allows a single cluster of up to eight nodes, now with Secure Path protection.

Single-path (single controller, non-Secure Path) NetWare clustering has been successfully tested up to a 12-node

cluster. NetWare clusters employing Secure Path (dual controller, dual HBAs) are limited to six nodes. Multiple

NetWare clusters (and single servers) may have concurrent access with no limitation inherent to the MSA1000.

Likewise up to a 16-node Linux cluster (single controller, non-Secure Path) utilizing SteelEye LifeKeeper for Linux

clustering software has been tested and is supported. Presently a Linux/Secure Path configuration is limited to a

two-node cluster. Refer to

http://www.hp.com/go/securepath

for any restriction on Linux with Secure Path.

The MSA1000 has the ability to be configured with thirty-two LUNs. Best practices would dictate generally no more

than sixteen servers accessing a single MSA1000. More commonly, users have had an average of five to eight

nodes. This can be any combination of hosts or clusters with different operating systems while holding fast to the

guidelines and limits described in the above paragraphs. Performance within these guidelines is heavily dependent on

the actual number of end users and types of applications being employed.
