A company plans to implement SRDF/Star. It is currently using SRDF/S between their two data centers. It is setting up a third data center and wants to have at least two identical copies of its data in case of a primary site failure. What condition is needed for the connection between the first two sites and the third site?
Which metrics are recommended to start analyzing the overall efficiency of the array due to cache?
A company wants to implement a three -site disaster recovery solution. It is considering a Concurrent SRDF/Star environment where the production data on R11 devices are replicated to two R2 devices in two remote arrays. Site 2 will use SRDF/S links, and Site 3 will use SRDF/A links from Site 1. What is the correct configuration for recovery links?
An application server has the following data characteristics: 80% of the I/O is generated with 8 KB random small blocks 20% of the I/O is generated with 64 KB sequential large blocks 50% of all I/O is a write What workload profile do these data characteristics represent?
DRAG DROP A drive failure has occurred at a customer environment, and a service request has been opened with customer support. A drive failure has occurred at a customer environment, and a service request has been opened with customer support. Order the steps in sequence as part of key management. Explanation: he steps in sequence as part of key management for a drive failure on a PowerMax array are as follows: Spare drive invoked against failed drive. This step involves the system automatically selecting a spare drive and starting the sparing operation to rebuild the data from the failed drive. The spare drive is encrypted with a temporary key that is stored in the embedded key manager.1 1st entry in audit log. This step involves the system logging the sparing operation and the temporary key generation in the audit log, which records all key management activities and events.1 Sparing operation is completed. This step involves the system completing the data rebuild and marking the spare drive as a permanent replacement for the failed drive. The spare drive becomes part of the RAID group and inherits the same properties as the failed drive.1 Key is deleted from the repository when failed drive is removed. This step involves the system deleting the Data Encryption Key (DEK) of the failed drive from the embedded key manager when the failed drive is physically removed from the array. The DEK is a unique 256 -bit AES -XTS key that is used to encrypt and decrypt data on each drive.1 2nd entry in audit log. This step involves the system logging the DEK deletion and the failed drive removal in the audit log.1 Key is generated for the replacement drive when installed. This step involves the system generating a new DEK for the replacement drive when it is installed in the array. The new DEK is stored in the embedded key manager and used to encrypt and decrypt data on the replacement drive.1 Reference: Dell EMC PowerMax and VMAX All Flash: Data at Rest Encryption
A storage administrator migrated an AIX host using NDM. When they commit the migration, how is host access to the source array removed?
