Using SAN and Blades for HBase/Hadoop cluster
Hi,
Is it recommended to use blades and SAN for hadoop/hbase cluster nodes ? or
will it be more performant to use seperate server machines with dedicated
CPU/hard disks on each of them.
Could using SAN cause a bottleneck or degrade performance for hadoop
nodes(using the same SAN for all nodes).

Thanks & Regards
Himanish

In general, Hadoop applications will perform much better with dedicated
local disks (don't use RAID for data drives, either).

You'll get the best performance out of dedicated hardware.
