Questionnaire below for Symmetrix & Netapp:

Symmetrix

1. Have you worked on replication technology on symmetrix like SRDF and TimeFinder?Ans. Should be Yes.

2. How do you manage symmetrix? symmcli or ECC?

Ans. should be through symmcli.3. What is Architectural difference between legacy symmetrix with current DMX?

Ans. Direct MAtrix Architecture, point to point topology.

4. What are mirror positions in DMX?

Ans. there are 4 mirror positions (M1, M2, M3 and M4).M1 and M2 used for std device

M3 used for BCV or SRDF

M4 used for SRDF or BCV5. Whats the command to create meta?

Ans. Form meta from device config=striped or concatanated stripe_size-1920;

6. In SRDF what is the difference between suspend and split?

Ans. In suspend status the I/O's are suspended to R2 volume and R1 is in read/write modeand R2 in write disabled mode

In split status both devices are independent and R1 and R2 both are in read/write mode.
