HPE StoreOnce Disk Performance Test

The HPE StoreOnce appliance consists of disks for data storage and an operating system. Any processing bottlenecks on these disks can significantly delay reading from and/or writing to the disks, thereby adversely affecting the user experience. If any of these disks fail or slow down due to processing bottlenecks and space constraints, backup and restore operations fail. To prevent all these catastrophic outcomes, administrators must keep an eye on the disk usage and on the I/O activity on each disk of the backup appliance, detect any slowdowns or disk failures well before users notice them, and take pre-emptive action.The HPE StoreOnce Disk Performance Test helps administrators with the same.

This test closely monitors the disk usage and level of I/O activity on the operating system and data disks of the target backup appliance and helps to detect any overload conditions, space contention, and processing slowdowns in the disks before they lead to the failure of the backup and restore operations.

Target of the test : HPE StoreOnce Backup 4.x

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the OS and Data disks on the HPE StoreOnce Backup 4.x appliance being monitored.

Configurable parameters for the test

Parameters	Description
Test Period	How often should the test be executed.
Host	The host for which the test is to be configured.
Port	The port at which the host is listening. By default, this is set to Null.
Username and Password	By default, the eG agent executes REST APIs on the target HPE StoreOnce Backup 4.x appliance to collect the required metrics. For the eG agent to execute the REST APIs, a special user with an Observer role is required. Specify the credentials of such a user in the Username and Password text boxes.
Confirm Password	Confirm the password by retyping it here.
Timeout Seconds	Specify the duration (in seconds) beyond which the test will timeout in this text box. The default value is 120 seconds.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Percentage of disk usage	Indicates the percentage of space utilized on this disk.	Percent	A value close to 100% may indicate a potential problem situation that requires immediate attention.
Read throughput	Indicates the rate at which the data was read on this disk.	MB/Sec	A high value is desired for this measure. A low value indicates processing bottlenecks that may lead to performance degradation.
Write throughput	Indicates the rate at which the data was written from this disk.	MB/Sec
Reads	Indicates the rate at which the read operations were performed on this disk.	IOPS	Ideally, the value of this measure should be high. A steady dip in this measure value could indicate a potential reading bottleneck.
Writes	Indicates the rate at which the write operations were performed on this disk.	IOPS	Ideally, the value of this measure should be high. A steady dip in this measure value could indicate a potential writing bottleneck.
