The EMC XTREMIO 1/2/3 Monitoring Model
eG Enterprise offers a specialized EMC XtremIO 1/2/3 monitoring model that monitors each of the key indicators of the performance of EMC XtremIO - such as the SSDs, X-Bricks, volumes, target ports, initiators, etc. - and proactively alerts administrators to potential performance bottlenecks, so that administrators can resolve the issues well before end-users complain.
Figure 1 : The layer model of EMC XtremIO 1/2/3 storage array
Each layer of Figure 1 above is mapped to a variety of tests, each of which report a wealth of performance information related to the EMC XtremIO storage array. Using these metrics, administrators can find quick and accurate answers to the following performance queries:
- How well the bandwidth is utilized in each Data Protection Group?
- How well read/write operations were performed on each Data Protection Group?
- How much of space is utilized in the SSDs of each Data Protection Group?
- How well read/write operations were performed on each SSD?
- What is the current state and CPU utilization of each X-Env?
- What is the current health of each cluster? Which cluster is too slow in processing I/O requests? What type of I/O requests are processed very slowly - read or write requests?
- How well each data block in a cluster is processed? Which data block size is the slowest to be processed causing bottlenecks?
- What is the current port state and health of each target port? How well read/write operations are performed through each target port? Which target port is the slowest in performing read/write and I/O operations?
- What is the current state of each X-Brick? How many SSDs and Battery Backup Units are present in each X-Brick?
- How well read/write operations were performed on each volume? Which volume is handling the maximum amount of I/O?
- How well the space of each volume is utilized?
- How well read/write operations were performed on each volume folder? Which volume folder is handling the maximum amount of data?
- How well read/write operations were performed through each initiator? Which initiator is taking too long to perform the I/O operations?
- How well read/write operations were performed on each initiator group? Which initiator group is handling the maximum I/O operations?
- How well read/write operations were performed on each initiator group folder? Which folder is handling the maximum I/O operations?
- How well read/write operations were performed on each snapshot? Which snapshot is experiencing a processing bottleneck?
The tests pertaining to this monitoring model have already been discussed in detail in The EMC XTREMIO 4.x Monitoring Model.
