Log Check Result — View the log check result. Can we safely replace a drive? Symmetrix DMX-4 architecture Flash drives cannot be used as vault devices. This dynamically adjusting algorithm saves disk seek and latency time by destaging data in groups of up to four tracks concurrently per logical volume. Reduced mirror positions giving customers good flexibility for migration and other opportunities. The DMX-4 illustrations are used unless the other model screens are a different form, fit, or function.

Place Command Line beneath terminal — Places the command line beneath the terminal screen. Symmetrix data integrity protection features The Symmetrix system is designed with these data integrity features: Health Check This tab allows you to view the health check result.

When you start SymmWin again, execution of the tasks resumes from the point of departure. Adhering to the configurations stated for each model type ensures that the physical routing of the serial signals minimizes contention for memory resources, maximizes bandwidth within the system, and maintains total redundancy to the same memory location through two completely different hardware paths.


Striping data across the multiple drives is designed to benefit random reads by avoiding stacking multiple reads to a single spindle and disk director. SMC accelerates FBA and CKD device management tasks, for example, enabling administrators to configure or replicate devices with a few clicks and keystrokes and to duplicate devices with simple templates containing device attributes such as capacity, configuration, and emulation type.

Also known as gateway. Microcode has been build on base from previous generation DMX Usually, a Symmetrix volume will be presented through one host channel. DMX-4 configuration rules and guidelines The following are some of the system configuration rules and guidelines to consider when planning your new or upgrading your DMX-4 system: See also Unit Address.

This is a high-speed communications fabric within the DMX-4 that allows for fast, reliable messaging between compute nodes. Sometimes it is convenient to see a list of files, and to open them with a click. The Symmetrix DMX-4 connects directly to host processors through physical channel attachments. Each track contains certain nondata information such as the address of the track, the address of each record, the length of each record, and the gaps between each areaand data information.

Meta volumes can be configured on Flash drives as long as all of the logicals in the Meta group are on Flash drives.

Splitting the director functions eliminates the processing overhead and global memory locking associated with Control Units that perform both functions. File Selector — The log browser can open an essentially unlimited number of files. Each disk director on a Symmetrix DMX system supports eight internal links to global memory. Flags — Lists the debug flags.


High-speed global memory Global memory speed is greater than the total speed of all components for example, the directors that access it. You can set a markpoint by clicking in the left border of the browser window, by pressing M markpointor by pressing Alt simultaneously with the number 0 through 9 that identifies the markpoint. Very large eight disk director configurations may be limited or restricted by currently available Symmetrix DMX-4 maximum memory. Print — Prints the log file information.

Refer to Prodjct 93 on page A component that is replaced or added by service personnel as a single entity. To let users view all communications from a single terminal, Inlines provides the All Terminal option. SMC security features include user authentication, restricted user roles, management of Symmetrix Access Controls, and management of the Symmetrix Audit Log.

This section describes the huide procedure only. Error — Failure reason. End selection at cursor — Ends log file block at cursor. Striping is carried out in units of 64 memory words 1 across the four regions of each global memory director. The fabric manager is assigned to any one of the director processors and communicates to the fabric through special in-band fabric management packets.

giude Save data table to binary file — Saves table to binary file. You can, however, select many buttons that contain text. These directors can co-exist in the same system with any existing DMX-4 channel directors.

This displays director board status. As the markpoint is set, a yellow number appears in the left border, identifying the mark.
