I'm in need of some advice with regard to a hardware configuration of Management nodes in a soon to be production cluster.
Hardware was purchased for an HDP Production cluster prior my involvement.
The hardware specs for 6 Management Nodes is as follows:
- 2x 10 core Xeon
- 128GB of RAM
- 2x 300GB SAS for OS
- 4x 400GB SAS SSD's for application related Services in a RAID 10 configuration.
We're trying to determine if the disk space will be adequate to handle a 150 Node Cluster and expansion up to 250 in the future.
I would say go with 256 gb ram. but 128 is def do-able and often seen in the field. Go with Dual 10Gbps NIC. I would go with at least 12-2TB drives broken down into
2 OS drives with raid-1 mirror.
6 drives in raid-10 (metadata)
4 spare drives
