Clustered Storage Arrays — Network Performance Metrics

These metrics describe the performance of an EqualLogic array’s network and an Isilon array’s internal and external networks.

 

Table 23. Network Performance Metrics

Display Name	Description	Topology Name
Link Speed	Current operational speed of the port link.	currentSpeedMb
Max Port Speed	Rated maximum speed of the port	maxSpeedMb
Packet Errors %	Number of incorrectly received data packets divided by the total number of received packets, expressed as a percentage.	packetErrorPercent
Rcv Data Rate	Bytes per second received through a port or group of ports.	bytesWrite
Send Data Rate	Bytes per second sent through a port or group of ports.	bytesRead
Rcv Util	= Rcv Data Rate / Link Speed	bytesWriteUtilization
Send Util	= Send Data Rate / Link Speed	bytesReadUtilization
Rcv Util (% of max)	Also NW Rcv Util (% of max) = Rcv Data Rate / Max Port Speed	bytesWriteUtilizationMax
Send Util (% of max)	Also NW Send Util (% of max) = Send Data Rate / Max Port Speed	bytesReadUtilizationMax

Capacity Metrics

The selection of capacity metrics displayed in any given dashboard depends on the selected device type and the metrics available from the device vendor. The following tables define each metric and shows the topology name for the metric. You need the topology name when referencing the metric in user-defined rules and dashboards.

Capacity metrics are organized into the following categories:

•	Storage Arrays — Array, Member, and Pool Capacity Metrics

•	Filers — Filer and Aggregate Capacity Metrics

•	Storage Arrays and Filers — LUN, NASVolume, and Disk Capacity Metrics

Storage Arrays — Array, Member, and Pool Capacity Metrics

The following table contains the capacity metrics you may see displayed for storage arrays, members/nodes, and pools.

 

NOTE: To view the metrics for EMC Isilon arrays (which are significantly different than other arrays), see EMC Isilon Only Capacity Metrics.

 

Table 24. Array, Member, and Pool Capacity Metrics

Capacity Metric	Description	A	M	P	Topology Name
Total Advertised LUNs Size	Also Advertised LUNs Size Sum of the Advertised LUN Size for all LUNs in the entity.				conf_LunSize
Available Raw Capacity	Capacity available in the pool that has not been committed to data, snapshots, or thick-provisioned LUNs. Raw counts all the disk blocks available, before applying RAID.				raw_available
Available Usable Capacity	Also Available Capacity Capacity available in the pool that has not been committed to data, snapshots, or thick-provisioned LUNs. Usable means after applying RAID.				conf_available
Capacity Provisioned to LUNs	Also Provisioned to LUNs Capacity used for LUN data. Does not include capacity that is used for snapshots, reserves, etc. • For thin-provisioned LUNs, this is the capacity used for data written to the LUNs. • For thick-provisioned LUNs, this is the capacity allocated to the LUNs, and does not reflect data written Formerly displayed as Consumed Capacity.				Array: lun_usable_capacity Pool: conf_used
Overcommitment	= Total Advertised LUNs Size – Total Usable Capacity Overcommitment reflects the minimum additional capacity needed in the pool to support the advertised capacity promised to thin-provisioned LUNs. When the value of overcommitment is greater than zero, you run the risk of I/O writes failing because of insufficient physical storage to support the demand. Overcommitment is available only for arrays where the vendor provides the total usable capacity.				conf_LunOvercommitted
Total Disk Capacity	Sum of the sizes of the disks in the array. This includes spares.				disk_capacity
Total Raw Capacity	Total capacity of the pool in raw terms. Raw counts all the disk blocks allocated to the pool, before applying RAID.				raw_capacity
Total Usable Capacity	Total capacity of the pool or member/node in usable terms. Pools that are defined with a specific RAID level have this metric. Pools that can support LUNs with different RAID levels do not have this metric.				conf_capacity
Used Capacity	= Total Usable Capacity - Available Usable Capacity.				conf_used
% Used	= Used Capacity / Total Usable Capacity Percentage of the member/node's usable capacity that has been used.				Calculated
% of Pool	EqualLogic Pools-Members tab only. Percentage of the pool storage capacity provided by a pool member.				Calculated

EMC Isilon Only Capacity Metrics

Isilon arrays provide additional metrics to describe the Isilon OneFS file system (IFS) capacity in terms of hard disk drive (HDD) and solid state drive (SSD) capacity.

 

 

Table 25. EMC Isilon only Capacity Metrics

Capacity Metric	Description	A	M	P	Topology Name
Total HDD Capacity	Raw capacity of the hard drives in the array, as reported by the vendor.				raw_capacity_HDD
Total SSD Capacity	Raw capacity of the solid-state drives in the array, as reported by the vendor.				raw_capacity_SSD
IFS Capacity: Total	Total capacity of the Isilon File System.				Array: pool_capacity_conf Pool: conf_capacity
IFS Capacity	= Total HDD Capacity + Total SSD Capacity Capacity of the Isilon File System on a pool or member/node.				conf_capacity
IFS Capacity: Free	Also IFS Free Free capacity of Isilon File system.				Array: pool_free_conf Pool and member: conf_available
IFS Capacity Used	= IFS Capacity - IFS Capacity: Free				Calculated
IFS Capacity: HDD Total	Capacity of Isilon File System on hard disk drives in an array, pool, or node.				conf_capacity_HDD
IFS Capacity: HDD Free	Free capacity of Isilon File System on hard disk drives in an array, pool, or node.				conf_available_HDD
IFS Capacity: HDD Used	= IFS Capacity: HDD Total - IFS Capacity: HDD Free				Calculated
IFS Capacity: SDD Total	Capacity of Isilon File System on solid state drives in an array, pool, or node.				conf_capacity_SSD
IFS Capacity: SDD Free	Free capacity of Isilon File System on solid state drives in an array, pool, or node.				conf_available_SSD
IFS Capacity: SDD Used	= IFS Capacity: SDD Total - IFS Capacity: SDD Free				Calculated
HDD % Free	= IFS Capacity: HDD Free / IFS Capacity: HDD Total				conf_pct_available_HDD
SDD % Free	= IFS Capacity: SDD Free / IFS Capacity: SDD Total				conf_pct_available_SSD
