Hi @ManishChawda !
GNS3 is a front end for several backends/hypervisors - Dynamips, QEMU, Virtualbox, VMware. We do not have images for those backends - neither Comware 7 (5510, 1950) nor ArubaOS (2530).
There is a standalone simulator HCL (search the forum for it) that simulates Comware 7 switches. AFAIK there is no ArubaOS simulator like GNS3 or HCL.
