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:
NOTE:NOTE:
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.

HP supports additional high availability multi-pathing capabilities within various operating systems and
through third-party vendors, providing continuous data access from HP's RAID MSA1000 to host servers.
Options are available for servers running the Windows and Linux, operating systems. More information
and the explanation of restrictions are available at
http://h18006.www1.hp.com/products/sanworks/multipathoptions/index.html
Microsoft Windows 2000 and 2003 (32 bit EE and 64 bit EE only)can utilize the HP MPIO Basic
Failover v1.0 for MSA Arrays, a DSM available for free download at the above site.
Unlike under Secure Path you are limited to a 4-node cluster.
Linux industry standard failover for the MSA1000 is available at no charge within the FCA2214
HBA device driver from QLogic.

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
