Hi Samson,
Please check the latest MDS interoperability support matrix:
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix1.html#wp647172
You can see that HP MSA 1000 & 1500 in the list with all the range of MDS products. (please check foot note under the HP MSA section)
And important thing is you need to refer to the following OSM(HP) website to obtain the latest support matrix:
HP—visit: HP StorageWorks SAN design reference guide http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00403562/c00403562.pdf?jumpid=reg_R1002_USEN
Please search with MSA , you will find the MSA 2000 models and it will mention H type switches which are Cisco and on page 93 on the HP pdf you will see all the MDS models that are supported.
I hope this answers your query and I hope it is not too late.
Thanks,
Ozden
