Model 452: Added HDD (HDFS)

Additional HDFS spinning storage for Limulus Hadoop Model 452

Increase the total amount of raw HDFS (Hadoop Distributed File System) storage for Limulus models 452. By default all four node Limulus Hadoop systems use a replication factor of two. This value can be changed at any time. The table provides the additional amount of usable HDFS storage using 2X replication.

Upgrade-Size (Raw)	HDD-Size	Drives	Additional-Drives/Motherboard	Warranty	Usable-at-2X-Replication
32 TB	8 TB	4	1	5-year	16 TB
48 TB	12 TB	4	1	5-year	24 TB
56 TB	14 TB	4	1	5-year	28 TB

The upgrade includes four HDD drives (spinning) that are inserted into the HDD drive cage onthe inside Limulus systems. One drive is connected to each of the four internal motherboards. Drives come pre-configured and ready for insertion. The Ambari web interface is used to tell Hadoop HDFS about the new drives. This upgrade can be purchased with a Limulus system or in the future. It requires adding four HDD drives to the existing HDD cages inside the case.
