-Re: hbase deployment using VMs for data nodes and SAN for data storage

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.
