  • Page 13: Getting Started

    Getting started Storage Management Utility (SMU) is a web-based application for configuring, monitoring, and managing the storage system. Each controller module in the storage system contains a web server, which you access when you sign in to SMU. In a dual-controller system, you can access all functions from either controller. If one controller becomes unavailable, you can continue to manage the storage system from the partner controller.

  • Page 17: About Volumes

    When a disk fails, the system looks for a dedicated spare first. If it does not find a properly sized dedicated spare, it looks for a global spare. If it does not find a properly sized global spare and the dynamic spares option is enabled, it takes any properly sized available disk.

  • Page 18: About Volume Mapping

    • Define CHAP secret in the host iSCSI initiator. • Request host login to the storage system. The host should be displayable by the system, as well as the ports through which connections were made. If it becomes necessary to add more hosts after CHAP is enabled, additional CHAP node names and secrets can be added.

  • Page 19: About Volume Cache Options

    About volume cache options You can set options that optimize reads and writes performed for each volume. Using write-back or write-through caching NOTE: Only disable write-back caching if you fully understand how the host operating system, application, and adapter move data. If used incorrectly, you might hinder system performance. You can change a volume's write-back cache setting.

  • Page 20: About The Snapshot Feature

    • The Maximum option lets the controller dynamically calculate the maximum read-ahead cache size for the volume. For example, if a single volume exists, this setting enables the controller to use nearly half the memory for read-ahead cache. Only use Maximum when disk latencies must be absorbed by cache.

  • Page 21: About The Volume Copy Feature

    The snapshot service has two features for reverting data back to original data: • Deleting only modified data on a snapshot. For snapshots that have been made accessible as read-write, you can delete just the modified (write) data that was written directly to a snapshot. When the modified data is deleted, the snapshot data reverts to the original data that was snapped.

  • Page 22: Creating A Volume Copy From A Master Volume Or A Snapshot

    Benefits include: • Additional data protection. An independent copy of a volume (versus logical copy through snapshot) provides additional data protection against a complete master volume failure. If the source master volume fails, the volume copy can be used to restore the volume to the point in time the volume copy was taken.

  • Page 23: About The Vds And Vss Hardware Providers

    About the VDS and VSS hardware providers Virtual Disk Service (VDS) enables host-based applications to manage vdisks and volumes. Volume Shadow Copy Service (VSS) enables host-based applications to manage snapshots. For more information, see the VDS and VSS hardware provider documentation for your product. About RAID levels The RAID controllers enable you to set up and manage vdisks, whose storage may be spread across multiple disks.

  • Page 25: About Size Representations

    About size representations In SMU panels, parameters such as names of users and volumes have a maximum length in bytes. ASCII characters are 1 byte; most Latin (Western European) characters with diacritics are 2 bytes; most Asian characters are 3 bytes. Operating systems usually show volume size in base 2.

  • Page 26: About Storage-Space Color Codes

    About storage-space color codes SMU panels use the following color codes to identify how storage space is used. Table 9 Storage-space color codes Area Color Meaning Overview panels Total space Available/free space Used space Reserved space, used for parity and snap pools, for example Vdisk panels Space used by spares Wasted space, due to use of mixed disk sizes...

  • Page 27: About Data Protection In A Single-Controller Storage System

    About data protection in a single-controller storage system A 2000 G2 Modular Smart Array storage system can be purchased or operated with a single controller. Because single-controller mode is not a redundant configuration, this section presents some considerations concerning data protection. A volume’s default caching mode is write back, as opposed to write through.
