Storage Performance Management

Storage Performance Management

Describes how to configure performance.

Performance Configuration

Describes how to configure performance.

Context

To collect storage device performance data, enable the performance monitoring function first and configure time synchronization between eSight and the device.

Procedure
  • Enable the performance monitoring function of the storage device.

    Go to the storage device management interface. A Huawei storage device is used as an example. The operation procedure is as follows:

    1. On the menu bar, choose Resource > Storage Subnet.

    2. In the navigation tree, choose Storage > Storage Device.
    3. In the function pane, click the device name.
    4. Enable the performance monitoring function, ensure that performance files of the storage device can be generated properly. For details, see the OceanStor DeviceManager Online Help.

      You can perform the following operations to enable the performance monitoring function for 5800 V3:

      1. On OceanStor DeviceManager, choose Settings > Performance Monitoring Settings.
      2. On the Performance Monitoring Settings page, select Parameter Settings.
      3. Select Save monitoring data on the device and set the performance monitoring status to Enabled.

  • Configure storage device time.
    1. Change the storage device time to make it consistent with the eSight server time. For details, see the OceanStor DeviceManager Online Help.

      You can perform the following operations to change the time of 5800 V3:

      1. On OceanStor DeviceManager, choose Settings > Basic Information.
      2. On the Basic Information page, select Device Time.
      3. Select Manual and click Modify.
      4. Set the system time to make it consistent with the eSight time.

Configuring Real-time Performance Data Collection

After this operation is complete, the real-time device performance data displayed on the performance data page includes the historical performance data of the last hour.

Context

To set the performance collection period for a device, you can select the device on the storage device page and click Set Performance Monitoring, as shown in Managing All Storage Devices.

Procedure
  1. On the menu bar, choose Resource > Storage Subnet.

  2. Choose Configuration > Real-time Performance Collection from the navigation tree.
  3. Select devices to be configured on the left and click to add the devices to the area on the right.

    NOTE:
    • Devices of OceanStor V300R003C00, OceanStor V500R007C00, and later versions are supported. A maximum of 20 devices can be configured.
    • OceanStor 18000-series devices are not supported.
    • The left area displays all devices for which the real-time performance collection function can be configured and the right area displays devices for which the real-time performance collection function has been configured.
    • You can select devices on the right and click to delete them.

  4. Click Save.

    NOTE:

    You can perform the following operations for verification.

    1. Choose Performance > Performance Data.
    2. Choose Huawei Storage(Enterprise Storage) > Controller.
    3. Select a device for which the real-time performance collection function has been configured and click Real-time Details. The historical performance data of the last hour is displayed.

Function Description

This section describes the performance statistics supported by the storage device.

Application Scope

The following performance indicators can be collected:

  • Device
  • Controller
  • Storage pool
  • Front-end host port
  • Back-end port
  • LUN
  • File system
  • Hard disk
  • Logical host
NOTE:
  • OceanStor 18000 V100R001C00 storage devices do not support historical performance data collection.
  • Only OceanStor V3 storage devices of V300R002 or later support file system performance collection.
Collection Period Setting

Set the storage performance collection task according to the following table.

NOTE:

The performance data of a storage device depends on the performance data of the controller. If the performance data collection period of a device is changed, you need to change the performance collection task period of the controller to be the same as that of the device collection task.

Scenario

Number of Equivalent NEs

Collection Period

High configuration

CPU: 40-core, 2 GHz

Memory: 64 GB

Hard disk: 1 TB. The disk I/O speed must be greater than or equal to 100 Mbit/s. It is recommended that the disk I/O speed be greater than 180 Mbit/s.

Number of equivalent NEs ≥ 2000

30 minutes or higher

960 ≤ Number of equivalent NEs ≤ 2000

15 minutes

Number of equivalent NEs ≤ 960

5 minutes

Standard configuration

CPU: 12-core, 2 GHz

Memory: 32 GB

Hard disk: 500 GB. The disk I/O speed must be greater than or equal to 100 Mbit/s. It is recommended that the disk I/O speed be greater than 180 Mbit/s.

Number of equivalent NEs ≥ 1000

30 minutes or higher

480 ≤ Number of equivalent NEs ≤ 1000

15 minutes

Number of equivalent NEs ≤ 480

5 minutes

The following table describes how to calculate the number of eSight storage devices and number of equivalent NEs.

NOTE:

Storage devices are classified into high-end storage devices, mid-range storage devices, and low-end storage devices. For details about device models, see Supported Devices released with the version.

Device (1 Set)

Number of Equivalent NEs

High-end enterprise storage device

160

Mid-range enterprise storage device

20

Low-end enterprise storage device

10

Distributed storage device

160

Third-party storage device

10

Collection Unit Quantity Setting

The number of collection units supported by eSight during performance collection is calculated as follows: Number of collection units = Number of resources x Number of performance indicators x (15 minutes/collection period). The resources include devices, boards, and interfaces. The performance indicators include the CPU usage and memory usage.

NOTE:

If the number of collection units exceeds the maximum, the pressure on eSight is huge and performance collection may time out.
