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. i Sent from my iPad with iMstakes On Oct 15, 2012, at 21:46, "lars hofhansl" <[email protected]> wrote: If you have a SAN, why would you want to use HBase? -- Lars ________________________________ From: "Pamecha, Abhishek" <[email protected]> To: "[email protected]" <[email protected]> Sent: Monday, October 15, 2012 3:00 PM Subject: hbase deployment using VMs for data nodes and SAN for data storage Hi 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.
