Hi, I will go straight to the point, we are purchasing hardwares for going live. Currently we are targeting a data capacity of ~5TB with a view to increase capacity as the load increases. I have attached a tentative schematic as attachment. Please give us feedback on the network organization and additional tools as you see necessary.
* The HBase cluster will be in a separate 1Gbps network, connected through a managed switch. * Currently we do not have any MapReduce jobs, only Gets and occasional Scans. All searches are done using Solr. Application layer caching will also be in place. * 6 DN+RS, each with 1TBX4 7.2k RPM Enterprise HDD, 12GB ECC RAM, 1 X X3440/E5560 (4C/8T) * 1 NN+MN RAID 1 with 400GB 15k SAS HDD, 12GB ECC RAM, 1 X X3440/E5560 (4C/8T) * ZK - 500GB 7.2k RPM, 4GB ECC RAM, 1 X X3440/E5560 (4C/8T) * ZK + Gangrila + Nagios - 500GB 7.2k RPM, 8GB ECC RAM, 1 X X3440/E5560 (4C/8T) It would really be helpful for me if you would kindly help us on whether these configurations are sufficient or not. The nature of the application running is a E-Commerce PaaS initially. Later when we add additional applications to the stack we will be able to increase the capacity.
