INTRODUCTION This paper outlines support of Windows Client (XP, Vista, and Windows 7), Linux (RHEL and SUSE) and Mac (OS X 10.5 – 10.6.x) with IBM DS3000, DS4000, and DS5000 Storage Servers. It also discusses support in StorNext environments. The solutions discussed arose because of customer demand seen in the media and entertainment industry and within the oil and gas industry.
Mac, Windows and Linux Client Connectivity In recent years, the workflow requirements of the video professional is driving the need for more sophisticated, high-end configurations, which require multiple users to share access to large amounts of data while maintaining the high-throughput performance required for the rich media and content applications they serve.
There are three components to the basic StorNext solution: Clients, Meta Data Controllers (MDCs), and the storage. There are also ancillary components such as the SAN, the TCP/IP network, and optional archive storage such as tape libraries or second tier disks. However, for selling and support purposes the components are software, support, and implementations services.

Note: A customer seeking connection that has already deployed Apple Xsan MDC will need to transition to a Quantum StorNext MDC running either on Linux or Windows Server. However the Apple Xsan clients can remain.

The first is that the SAN design is architected to avoid logical drive failover in the storage subsystem.
Storage Controller A Controller B Up to 8 Up to 8 All ports see all MDC and client ports All ports see all MDC and client ports RECOMMENDED RAID CONFIGURATIONS RAID RAID Array Segment Disk type level size size Journal 1 or 10 As required 256 FC or SAS recommended Meta Data 1 or 10 As required 256 FC or SAS recommended • Journal and Meta Data may reside in separate LUNS carved from the same RAID Array if required in small implementations.
SOLUTION INSTALLATION 1. Use a meshed fabric with each HBA zoned to see both controllers but controllers unable to see each other. 2. Use RDAC or MPIO failover drivers as appropriate for your operating systems (ATTO for Apple and/or Windows XP, Vista, or Windows 7). Do not use the StorNext failover driver 3. For Installations that include Apple (MacOS) or Windows (XP, Vista, Windows 7) Clients a. Set host type MacOS b. This will : 1. Set TPGS On 2. Set AVT Off c.
9. For clients, limit the number of defined paths to four. This gives you the redundancy you need while minimizing boot time. During boot, StorNext tries EVERY defined path. 10. RAID 1 or 10 for Journal and Meta Data a. Multiple RAID 1 Groups would be preferable to a similarly size RAID 10 b. Placing Meta Data and Journal on a storage system separate from the data is preferable. 11. It is desirable to separate Meta data and Journal LUNS from the Data LUNS. a.
MIGRATING FROM XSAN MDC TO STORNEXT MDC Q. Are there new features in Xsan 2.2 that make it harder to swap out XServe MDCs and replace them with StorNext Linux MDCs? A: “NamedStreams” is the Apple Xsan feature that causes some problems with StorNext. If you don’t turn it on, you’re fine. By default, “NamedStreams” is turned on. NamedStreams will make things like the basic StorNext command line copy command, cvcp, not work. Before Xsan 2.2, you could have it copy the “.

APPENDIX A: EXAMPLE CONFIGURATIONS Large Heterogeneous StorNext configuration Example 1.Drawing depicts large and expandable SAN with heterogeneous client connectivity. Multiple DS5300 connected to meshed SAN fabric with a minimum of two Fibre Channel switches. For DS5100/DS5300 configurations, a minimum of two switches is recommended. Drawing shows multiple DS5300 for Data storage and a separate DS5020 for Meta Data. Digital Media Storage Solution Installation Guide © Copyright 2011, IBM Corporation.
Detailed explanation of example 1. Example Large StorNext configuration showing DS5300’s with Fibre Channel and/or SATA disk for Data and a separate DS5020 for Meta Data and Journal. These examples are representative only and should not be seen as restrictive. The idea is to use our knowledge of these products to craft solutions with the proper performance and resiliency characteristics to meet customer needs and budget concerns.
Mid to large -sized “MAC Homogenous”StorNext configuration Example 2. In this example diagram Linux MDC Servers are shown, but only MAC Xsan Clients are shown. DS5300 connected to meshed SAN fabric with a minimum of two Fibre Channel switches. For DS5100/DS5300 configurations, a minimum of two switches is recommended. Drawing shows minimal SAN to DS5300 connections to simplify the drawing. However, up to 16 connections is supported.
Mid-sized “MAC Homogenous”StorNext configuration Example 4. In this example diagram Linux MDC Servers are shown, but only MAC Xsan Clients are shown. DS5020 connected to meshed SAN fabric with a single Fibre Channel switch. For DS5020 configurations, Multiple Fibre Channel switches are not required, but they are recommended. Drawing shows minimal SAN to DS5020 connections to simplify the drawing. However, up to 8 connections are supported.
Small “MAC Homogenous”StorNext configuration Example 5. In this example diagram Linux MDC Servers are shown, but only MAC Xsan Clients are shown. DS3400 connected to meshed SAN fabric with a single Fibre Channel switch. For DS3400 configurations, Multiple Fibre Channel switches are not required, but they are recommended. Drawing shows minimal SAN to DS3400 connections to simplify the drawing. However, up to 4 connections are supported.
Mid to large -sized Heterogeneous StorNext configuration Example 6. Drawing depicts mid to large size and expandable SAN with heterogeneous client connectivity. DS5300 connected to meshed SAN fabric with a minimum of two Fibre Channel switches. For DS5100/DS5300 configurations, a minimum of two switches is recommended. Drawing shows minimal SAN to DS5300 connections to simplify the drawing. However, up to 16 connections is supported.
