Measures reported by VNXeNFSTest

By continuously monitoring the NFS operations on every storage processor, you can easily identify that storage processor on which NFS is most ineffective/problematic. This is where, the VNXeNFSTest test helps. This test monitors the NFS reads and writes performed on each storage processor in the target storage system and reports the following:

  • How well the I/O operations were performed using the NFS protocol, and whether any delays were noticed;

  • The total amount of data transacted when performing NFS reads and writes

These statistics will not only enable administrators to promptly detect current or probable latencies in I/O operations when using NFS, but will also help them figure out which I/O activity was most latent - i.e., whether reading or writing - and on which storage processor.

Outputs of the test : One set of results for each Storage Processor of the target storage system being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
readBandwidth Indicates the maximum amount of data read through NFS protocol from this storage processor per second. MB/sec The detailed diagnosis of this measure lists the VNX time, name of the storage processor and read bandwidth of the storage processor.
avgReadBandwidth Indicates the average amount of data read through NFS protocol from this storage processor per second. MB/sec  
writeBandwidth Indicates the maximum amount of data written using NFS protocol to this storage processor per second. MB/sec The detailed diagnosis of this measure lists the VNX time, name of the storage processor and write bandwidth of the storage processor.
avgWriteBandwidth Indicates the average amount of data written using NFS protocol to this storage processor per second. MB/sec  
readIOPS Indicates the maximum number of read operations performed using NFS protocol on this storage processor per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and read IOPS of the storage processor.
avgReadIOPS Indicates the average number of read operations performed using NFS protocol on this storage processor per second. IOPS  
writeIOPS Indicates the maximum number of write operations performed using NFS protocol on this storage processor per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and write IOPS of the storage processor.
avgWriteIOPS Indicates the average number of write operations performed using NFS protocol on this storage processor per second. IOPS Compare the value of this measure across the storage processors to figure out the storage processor that is performing the maximum write operations.
totalIOPS Indicates the total number of I/O operations performed using NFS protocol on this storage processor per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and total IOPS of the storage processor.
avgTotalIOPS Indicates the average number of I/O operations performed using NFS protocol on this storage processor per second. IOPS
