Storage Resource Management Introduction

Storage Resource Management Introduction

This section describes the functions and application scenarios of storage subnet management.

Definition

The storage subnet management function enables users to uniformly manage various types of storage devices from multiple vendors, including discovering and monitoring storage devices and hosts.

Functions

Discovering storage devices:

This function can discover storage devices and hosts, and support single addition, batch import, and automatic discovery.

Figure 10-1 Automatically discovering storage devices

Monitoring storage devices:

  • This function can monitor information such as the status, alarm, performance, and capacity of the storage device.
    Figure 10-2 Querying storage device details
  • This function can evaluate the health status of storage devices.
    Figure 10-3 Health status management

Application Restrictions

  • To ensure that the license resources can successfully connect to eSight during routine O&M, eSight sets major alarm thresholds for resource control items by default. eSight reports an alarm when the license resource usage reaches or exceeds the threshold (80% by default). When the usage of license resource items reaches the upper limit, license resources cannot continue to connect to eSight.
  • The alarm management function of eSight does not support SNMPv1. To manage device alarms using eSight, you must use SNMPv2c or SNMPv3.
  • It is recommended that a device be managed by only one eSight. Otherwise, device performance will be affected.
  • Currently, storage resource management does not support the DST function.
  • The session timeout interval configured on the device must be longer than the ping period between eSight and the device. Otherwise, an alarm indicating that the device information fails to be obtained is generated when a device is connected to eSight. The default ping period between eSight and the device is 5 minutes. You are advised not to change the ping period. For details about the session timeout interval configured on the device, see the product documentation of the device.
  • The polling period of eSight depends on the scale of equivalent NEs. You need to set the polling period based on the site requirements.

    Scenario

    Number of Equivalent NEs

    Polling 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 MB/s. It is recommended that the disk I/O speed be greater than 180 MB/s.

    Number of equivalent NEs ≥ 1000

    6 hours or longer

    Number of equivalent NEs < 1000

    1 hour or 6 hours

    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 MB/s. It is recommended that the disk I/O speed be greater than 180 MB/s.

    Number of equivalent NEs ≥ 500

    6 hours or longer

    Number of equivalent NEs < 500

    1 hour or 6 hours

KPIs

  • If eSight is deployed on a server with standard configuration, it can manage a maximum of 500 entry-level storage devices, 250 mid-range storage devices, or 30 high-end storage devices.
  • If eSight is deployed on a server with high configuration, it can manage a maximum of 2000 entry-level storage devices, 1000 mid-range storage devices, or 125 high-end storage devices.
