1.9 Performance

You need to be able to improve the I/O performance for your storage solution and to make the best use of the storage resources you have available. Your system must perform well for the number of users and the amount and type of data served. As the number of users increases, the amount of storage space and the performance demands also increase.

Storage Requirement

Novell OES Solution

Enhanced I/O performance: The ability to improve the I/O performance as experienced by your customers and users.

OES supports software RAIDs, which allows multiple disk I/O access. NSS supports RAIDs 0, 1, and 5. For Linux, NSS supports RAIDs 0 and 1. For information, see Managing NSS Software RAID Devices the OES 11 SP2: NSS File System Administration Guide for Linux.

Novell Cluster Services provides I/O access to data via multiple servers.

Optimized storage capability: The ability to grow, reorganize, reallocate, and restrict use of storage space, as needed, with minimal service interruption.

You can dynamically expand an existing NSS pool up to its 8 TB maximum by simply adding space to it. NSS volumes support volume, directory, and user quotas to govern space use.

OES 11 allows you to use the GPT (GUID Partition Table) partitioning scheme to specify devices up to 8 TB in size for NSS pools. The maximum pool size is 8 TB. Previously, NSS recognized devices only up to 2 TB in size.
