2
The new system also benefits from a file system known as GPFS that was developed at IBM Almaden to enable supercomputers faster data access.
该新系统也有益于IBM阿马尔登开发的用于使超级计算机快速读取数据的文件系统GPFS。
3
It allows users to perform SNMP service collection from a defined Linux OS collector node in the GPFS cluster to a management node.
用户可以在GPFS集群中定义的Linux操作系统收集器节点上执行SNMP服务收集，并将信息发送到管理节点。
4
The combination of GPFS and the DS4500 provides for a redundant storage subsystem in case of disk failure.
GPFS和DS4500共同构成了一个冗余存储子系统，预防磁盘故障。
5
GPFS allows both the master and backup nodes to have concurrent access to all of the files in the cluster.
GPFS允许主节点和备份节点并发访问集群中的所有文件。
6
With GPFS, for the file system to remain available, a quorum of nodes needs to be available.
通过GPFS，若要使文件系统保持可用，就需要有一个有效的节点仲裁。
7
These include the installation of the GPFS code on each node and the configuration of the Qlogic adapters for the storage nodes.
内容包括在每个节点上安装GPFS代码，以及为存储节点配置Qlogic适配器。
8
The GPFS portability layer (PL) is kernel-specific, and it must be created separately for each operating system level within your cluster.
GPFS可移植层（PL）是内核特有的，必须为集群中的每个操作系统级别单独创建。
9
GPFS uses this internode access to allow any node in the GPFS cluster to run relevant commands on other nodes.
GPFS使用这个中间节点的访问允许GPFS集群中的任何节点在其他节点上运行相关命令。
10
For this example, two main CSM groups are defined for use during the GPFS configuration, as shown below.
对于本例来说，我们定义了两个主要的CSM组在配置GPFS过程中使用，如下所示。
11
This file system is shared out to the other nodes, through GPFS or NFS.
该文件系统通过GPFS或者NFS，供其他节点共享。
12
It includes one large GPFS cluster split into two logical halves with a single large file system.
包括一个大型的GPFS集群，该集群分成两个逻辑部分，共用一个大型文件系统。
13
GPFS also enables a large system to keep track of its many files without laboriously scanning through every one.
GPFS也能够让一个大的系统记录很多文件而不必费力地扫描每个文件。
14
After this, with automount enabled, it mounts automatically when a node starts GPFS.
然后，如果启用了automount，就可以在节点启动GPFS时自动挂载。
15
This section covers in detail the steps taken in the creation of a GPFS cluster.
本节将详细介绍在创建GPFS集群过程中所需要的步骤。
16
The example setup uses CSM to install MSJ on every storage node as part of the GPFS installation.
示例设置使用CSM将MSJ作为GPFS安装的一部分在每个存储节点上进行安装。
17
For the example, one large GPFS file system is created using all the NSDs defined to GPFS.
对于本例来说，使用所有定义为GPFS的NSD创建了一个大型的GPFS文件系统。
18
It allows users shared file access within a single GPFS cluster and across multiple GPFS clusters.
它允许用户在一个GPFS集群和跨多个GPFS集群共享文件访问。
19
GPFS requires each cluster member to have a base set of GPFS RPMs installed.
GPFS需要每个集群成员都安装一个基本的GPFSRPM集。
20
The pagepool mechanism allows GPFS to implement read, as well as write, requests asynchronously.
pagepool机制允许GPFS将读请求与写请求异步实现。
21
You create the GPFS cluster for this example using several distinct steps.
您可以使用几个独特的步骤为这个例子创建GPFS集群。
22
Pick a GPFS cluster node to be the collector node.
选择一个GPFS集群节点作为收集器。
23
Instructions on installing and configuring GPFS.
关于安装与配置GPFS的说明。
24
Listing 1 shows output for a typical trap capture with snmptrapd; Listing 2 shows typical GPFS cluster information gathered from snmpwalk.
清单1显示用snmptrapd捕捉的一个典型陷阱。
25
A single network, a LAN or a switch, is used for GPFS communication, including the NSD communication.
一个网络、一个LAN或一台交换机用于GPFS通信，包括NSD通信。
26
Figure 1 shows the GPFS cluster configuration results used in this article.
图1显示了本文中使用的GPFS集群配置结果。
27
When you created the GPFS file system, you should have specified the number of copies of data and metadata as two.
在创建GPFS文件系统时，应该先将数据和元数据的副本数量指定为2。
28
The -r sets the full path for the remote shell program to be used by GPFS.
r为GPFS使用的远程shell程序设置完整路径。
29
There are four NSD nodes (also known here as storage nodes) in total: two in each logical half of the GPFS cluster.
NSD节点（即存储节点）一共有四个：GPFS集群的逻辑分区各两个。
