The EMC XTREMIO 4.x Monitoring Model

eG Enterprise offers a specialized EMC XtremIO 4.x monitoring model that monitors each of the key indicators of the performance of EMC XtremIO storage array - 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

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?
• What is the health of each BBU?
• Are the BBUs enabled?
• What is the charge that is remaining in each BBU?
• What is the current load on each BBU?
• Are the storage controllers enabled ?
• What is the health of each storage controller?
• What is the journalling health state of each storage controller?
• What is the current state of each slot?
• What is the current health state of each DAE Controller?
• Are the DAE Controllers enabled?
• What is the state of the SAS ports of each DAE Controller?
• Are the power supply units of each DAE Controller enabled?
• Are the infiniband switches enabled?
• What is the current health of each infiniband switch?
• What is the health of each storage controller?
• What is the front panel temperature of each storage controller?
• What is the current health of the power supply units of each storage controller?
• What is the state of the SAS ports of each storage controller?
• What is the state of each local disk added to the EMC XtremIO Storage array?
