StorageGrid notes

Day 1 Training Balancing Clinet access 1) No load balancing 2) DNS Round Robin 3) Connection Load balancer (CLB) service 4) Load balacer service. ( Recommended) Archive Node - VM -> About to extinct Optimal Storage Nodes Administrative Domain Controller ( ADC) Gateway ADC SSM LDR DMV Query ADC ADC returns list Gateway talk to LDR on node based on first one in the list When writes comes in 1) Goes to optimal 2) copy to second optimal 3) send ack when read request 1) Query the node 2) Query Cassandra database 3) Find which node has the data 4) send databack to node received request and send to user 5) LDR finds the node SG6060, SGF6060 SAS All Flash ILM protection policy rules Erasure coding Data pieces Parity Pieces Order of sequence 1) Dual commit on write 2) Ack 3) run ILM policy 4) ILM policy is long term protection ILM policy is the protection policy Workflow during object replication ILM engine in the LDR service evaluates ILM policy rules and determines that an object should be replicated 1) ILM engine sends a replicaiton request to the optimal Dest SN 2) Destination Storage Node LDR retrives object from SN 3) Destination storage node LDR writes to object storage 4) Destation storage node LDR sends object metadata to the DDS service 5) DDS service replicates the metadata and CMN service - runs on primary. configuration management while pimary is down -> you can not make any config changes, upgrades Chapter 2 Storage GRID Grid Manager 1) StorageGrid Topology tree 1) GRID Health 2) Information lifecycle management(ILM) activity 3) client activity Grid administrators use Grid manager to create 1) Storage tenant accounts, 2) manage ILM policiies and rules 3) configure grid nodes and services 4) perform maintenance Grid Topology Tree 1) Grid Site Grid Node Node services Service components Analyzing storage node SSM service components Storage Node Server status Monitor (SSM) service state number of threads CPU Load amount of memory consumed by the service Link Cost Cost of communication between data center sites ADC uses link cost to determine the Grid node to retrivet he object 0 -
