What is GPFS storage?
IBM General Parallel File System (IBM GPFS) is a file system used to distribute and manage data across multiple servers, and is implemented in many high-performance computing and large-scale storage environments. GPFS is among the leading file systems for high performance computing (HPC) applications.
Is GPFS NFS?
Note: GPFS on Windows does not provide NFS integration.
Is NFS a parallel filesystem?
The key difference between NFS and a parallel file system is that what happens in the data path is totally different. So the performance analysis techniques that you might have used with NFS are not the right techniques for a parallel file system.
Is FSx cheaper than EFS?
Pricing and availability. According to pricing at the time of this article, EFS will consistently be more expensive than FSx for Windows.
Is FSx a Lustre window?
Amazon FSx eliminates the traditional complexity of setting up and managing high-performance Lustre file systems, allowing you in minutes to spin up, run, and scale a battle-tested high-performance file system. It also provides multiple deployment options so you can optimize cost for your needs.
Can FSx be used with Linux?
Amazon FSx for Windows File Server (Amazon FSx) supports access from mixed Windows and Linux environments by fully supporting the SMB protocol. This includes access from Linux using the Linux SMB client.
How do I Create A GPFS cluster?
Each node is a GPFS server. The cluster is created using the mmcrcluster command. The GPFS cluster name is GPFS_CLUSTER1. The primary node (or NSD server; discussed in the next section) is aixlpar1p and the secondary node is aixlpar2p.
How do I configure GPFS on AIX?
The configuration can be as simple or complex as you want. We’ll assume that you have already purchased the necessary licenses and software for GPFS. With a copy of the GPFS software available, copy the GPFS file sets to each of the AIX nodes on which you need to run GPFS.
Why are the mm commands in GPFs failing to work?
The mm commands in GPFS require authentication in order for them to work. If the keys are not configured correctly, the commands will prompt for the root password each time and the GPFS cluster might fail. A good way to test this is to ensure that the ssh command can work unhindered by a request for the roots password.
What is the difference between/gpfs0 and/gpfs1?
The /gpfs (gpfs0) file system will be configured with a GPFS block size of 256K (the default) and /gpfs1 (gpfs1) with a block size of 1M*. Both file systems are configured for replication (-M2 –R2). The /tmp/cg/gpfs-disk.txt file is specified for /gpfs and /tmp/cg/gpfs1-disk.txt for /gpfs1.
