May be I didn't  understand your question. Do you mean SAN overshadows some of the hbase benefits?
I thought SAN isn't a great choice for hbase deployments because of concentration of iops
to a single device and thus losing out on parallelism and redundancy --  but I am no expert
on SANs. 

Anyways, to answer your question directly, we wanted to leverage the flexible keyvalue based
schema, ability to have a reliable MR type batch jobs infrastructure for analytics and the
linear scalability advantages of hbase.

If you have a SAN, why would you want to use HBase?

Subject: hbase deployment using VMs for data nodes and SAN for data storage


We are deciding between using local disks for bare metal hosts Vs VMs using SAN for data storage.
I was wondering if anyone has contrasted performance, availability and scalability between
these two options?

IMO, This is kinda similar to a typical  AWS or another cloud deployment.
