The SRDF establish operations speed is at least improved by 10X; see the numbers below in the performance data.

This is the message fabric, that is the interface between directors, drives, cache, etc. Prepare EMC structures 1. While the Permanent Spare or Dynamic Hot Spare is not invoked and is sitting in the machine waiting for a failure, these devices are not accessible from the front end customer. This form of SRDF is suggested to be implemented in a dmc environment. Depending on distance where these Symmetrix machines are located, this may have a significant impact on performance.

The operational mode for a device or group of devices can be set dynamically with the symrdf set mode command. Alternatively this problem of not having device mapped to at least one host can also be fixed by the PSE lab Mapping VCMDB to multiple hosts, channels may make the device venerable to crashes, potential tampering, device attributes and data change 50? Execute the following commands on both the local and remote hosts.

Copies data from R2 to R1 Actions: However, the latency due to propagation increases significantly with distance. EMC Engineering is the crown of EMC, inventing new technology and pushing the envelope in terms of defining future products, technologies and markets.

Restore copies data from BCV back to standard pair. The disadvantage is that anything towards that happens to the standard device will be reflected in the BCV mirror.

Additional software like Symmetrix Optimizer also uses the underlying BIN file infrastructure to make changes to the storage array to move hot and cold devices based on the required defined criteria.

Windows Thin PC Basic Only some changes now require traditional BIN file change, typically others are performed using symmetdix calls in enginuity environment.

An individual initiator can only belong to e,c Initiator Group. SRDF logically pairs a device or a group of devices from each array and replicates data from one to the other synchronously or asynchronously.

Systems with special requirements can be configured to drives instead of standard drives. You can id the logical device names by: There are s number of splits hyper per physical device.

Diskless R21 pass-through device, where the data does not get stored on the drives or consume disk. With this family of microcode Maintain the BCV as a split device to keep an online backup of the original data.

Enables a copy of only out-of-sync tracks to the BCV from its mirror. Autoprovisioning groups are supported through Symmetrix Management Console. With Enginuity EMC introduced the concept of single mirror positions.
