Use one or more of the following technologies:
Š
Multiple Path I/O : NSS helps prevent failure in the connection between the CPU and the
storage device by automatically identifying multiple paths between each NetWare server
and its storage devices.
For more information, see “
Managing Multipath I/O to Devices (NetWare) ” in the OES 2
SP2: NSS File System Administration Guide .
Š
Software RAIDs : NSS supports software RAIDS to improve storage availability and
performance by enhancing data fault tolerance and I/O performance.
For more information, see “
Managing NSS Software RAID Devices ” in the OES 2 SP2:
NSS File System Administration Guide .
Š Server Clusters : You can configure up to 32 NetWare servers or Linux servers into a high-
availability cluster where resources and services are dynamically allocated to any server in
the cluster and automatically switched to another server if the hosting server fails.
By manually switching services, IT organizations can maintain and upgrade servers
during production hours and eliminate scheduled downtime.
For more information, see the
NW6.5 SP8: Novell Cluster Services 1.8.5 Administration
Guide and the OES 2 SP2: Novell Cluster Services 1.8.7 for Linux Administration Guide .
13.1.6 NetWare Core Protocol Support (Novell Client Support)
on Linux
Many organizations rely on Novell Client
TM
software and the NetWare Core Protocol
TM
(NCP) for
highly secure file storage services.
Novell Storage Services (NSS) volumes are NCP volumes by nature, and you can also define Linux
POSIX volumes as NCP volumes. The main difference in access control between NSS volumes and
Linux POSIX volumes that are defined as NCP volumes is that NSS extended file and directory
attributes are not available on Linux POSIX volumes.
The NCP server for OES 2 lets you attach to Linux POSIX volumes that are defined as NCP
volumes using Novell Client software. For more information, see
Section 17.6, “NCP
Implementation and Maintenance,” on page 200 .
13.2 Planning OES File Storage
The following sections can help you plan for storage on your OES network:
Š
Section 13.2.1, “Directory Structures,” on page 128
Š Section 13.2.2, “File Service Support Considerations,” on page 129
Š
Section 13.2.3, “General Requirements for Data Storage,” on page 129
Š Section 13.2.4, “OES 2 Storage Planning Considerations,” on page 129
Š
Section 13.2.5, “NSS Planning Considerations,” on page 134
13.2.1 Directory Structures
To plan the directory structures you need on OES 2, see “ Understanding Directory Structures in
Linux POSIX File Systems ” in the OES 2 SP2: File Systems Management Guide .
