Dell PowerVault ME4 Series Storage System Administrator’s Guide

Enable or disable system-management settings

You can enable or disable management services to limit the ways in which users and host-based management applications can access the storage system. Network management services operate outside the data path and do not affect host I/O to the system. In-band services operate through the data path and can slightly reduce I/O performance.

1. Perform one of the following to access the Services options:
   • In the Home topic, select Action > System Settings, then click the Services tab.
   • In the System topic, select Action > System Settings, then click the Services tab.
   • In the banner, click the user panel and select Set Up System Services.
   • In the Welcome panel, select System Settings, and then click the Services tab.
2. Enable the services that you want to use to manage the storage system, and disable the others.
   • Web Browser Interface (WBI). The web application that is the primary interface for managing the system. You can enable use of HTTP and/or HTTPS for increased security, or of both. If you disable both, you lose access to this interface.
   • Command Line Interface (CLI). An advanced-user interface that is used to manage the system and can be used to write scripts. SSH (secure shell) is enabled by default. The default port number for SSH is 22. Telnet is disabled by default, but you can enable it in the CLI.
   • Storage Management Initiative Specification (SMI-S). Used for remote management of the system through your network. You can enable use of secure (encrypted) or unsecure (unencrypted) SMI-S:
     • Enable. Select this check box to enable unencrypted communication between SMI-S clients and the embedded SMI-S provider in each controller module using HTTP port 5988. Clear this check box to disable the active port and use of SMI-S.
     • Encrypted. Select this check box to enable encrypted communication, which disables HTTP port 5988 and enables HTTPS port 5989 instead. Clear this check box to disable port 5989 and enable port 5988. This is the default.
       NOTE:SMI-S is not supported for a system with 5U84 enclosures.
   • Service Location Protocol (SLP). Enables or disables the Service Location Protocol (SLP) interface. SLP is a discovery protocol that enables computers and other devices to find services in a LAN without prior configuration. This system uses SLP v2.
   • File Transfer Protocol (FTP). A secondary interface for installing firmware updates and downloading logs.
   • SSH File Transfer Protocol (SFTP). A secure secondary interface for installing firmware updates, downloading logs, and installing security certificates and keys. All data that is sent between the client and server is encrypted. SFTP is enabled by default. If selected, specify the port number to use. The default is 1022.
   • Simple Network Management Protocol (SNMP). Used for remote monitoring of the system through your network.
   • Service Debug. Used for technical support only. Enables or disables debug capabilities, including Telnet debug ports and privileged diagnostic user IDs.
     NOTE:Properly shut down the debug console by using the CLI command set protocols debug disable. Do not just close the console directly or by using the CLI command exit.
   • Activity Progress Reporting. Provides access to the activity progress interface using HTTP port 8081. This mechanism reports whether a firmware update or partner firmware update operation is active and shows the progress through each step of the operation. When the update operation completes, status is presented indicating either the successful completion, or an error indication if the operation failed.
   • In-band SES Capability. Used for in-band monitoring of system status based on SCSI Enclosure Services (SES) data. This service operates through the data path and can slightly reduce I/O performance. SES is disabled by default.
3. Perform one of the following:
   • To save your settings and continue configuring your system, click Apply.
   • To save your settings and close the panel, click Apply and Close.
   A confirmation panel appears.
4. Click OK.
