Data sharing is a must in today's modern computing world. When the data requirements include allowing a cluster of servers to access a common storage pool, Red Hat GFS is the answer for simplifying your data infrastructure, minimizing storage costs, adding storage on the fly, and achieving maximum uptime. A cluster file system like Red Hat GFS can be used with an IP network block-sharing protocol like iSCSI to provide scalable file serving at low cost. Network File System (NFS) is a common shared storage solution utilized by many infrastructures. However, in some instances, this solution does not scale. How do GFS and NFS compare? This article explains.
5. Optimizing NFS Performance Getting network settings right can improve NFS performance many times over -- a tenfold increase in transfer speeds is not unheard of. The most important things to get right are the rsize and wsize mount options. Other factors listed below may affect people with particular hardware setups.
SPEC SFS 3.0 (SFS97_R1) is the latest version of the Standard Performance Evaluation Corp.'s benchmark that measures NFS file server throughput and response time. It provides a standardized method for comparing performance across different vendor platforms. This is an incremental release that based upon the design of SFS 2.0 (SFS97) and address several critical problems uncovered in that release, additional it addresses several tools issues and revisions to the run and reporting rules.
In my last project at work, I had to replace NFS with GFS2 and Clustering. So in this tutorial I will show you how to create a Red Hat or CentOS cluster with GFS2. I will also show you how to optimize GFS2 performance in the next HowTo, because you will quickly notice some loss of performance until you do a little optimization first.I will 1st show you how do build a Cluster with GFS2 on the Command Line and in the next tutorial I will show you how to do the same thing using Conga.
Mac OS X and Mac OS X Server have been designed to fit into existing enterprise directory services. Appleâ„¢’s extensible Open Directory architecture integrates with standards-based LDAP directory services, including Sun JAVA Enterprise Directory Server a
How do I restart NFS server when network link goes down between two servers or NFS client / server under CentOS 4.x / RHEL / CentOS Linux 5.x? Forceful umount command result into more problems such as unresponsive NFS server and cold reboot only solves my
