The storage team at an organization is planning to migrate from an older Fibre Channel storage environment to a new environment using IP-based storage.
Which two switch features or characteristics are appropriate for IP storage networks? (Choose two.)
For IP storage networks, it is important to ensure that the switch features can handle the required bandwidth and prevent bottlenecks. Non-blocking switches are appropriate because they allow all ports to communicate simultaneously at full bandwidth, which is crucial for storage environments to maintain high performance and low latency. Deep or ultra buffered switches are also appropriate as they help to absorb bursts of traffic, preventing packet loss and maintaining steady data flow, which is important for the reliability of storage networks.
I'll go with DD and E too https://www.arista.com/en/solutions/ip-storage-network-infrastructures
D and E?
D and E too
The answer is D and E, according the dell documentation. https://www.dell.com/community/s/vjauj58549/attachments/vjauj58549/solutions-ch/488/1/h13104-dedicated-networks-for-ip-storage-wp.pdf
C & D are the best A >> FEX are used to add more network ports, it will not help specifically for storage B >> STP is here to avoid loops in the network, it is not specific to storage C >> Oversubscription has to be considered for storage network design, to find the best level between costs and performances D >> Yes : https://howdoesinternetwork.com/2015/what-is-a-non-blocking-switch E >> Deep buffered switches will degrade performances for storage networks : https://developer.nvidia.com/blog/maximizing-network-performance-for-storage-with-nvidia-spectrum-ethernet/
The answer is C & D, A = Fabric Extending is to expand number of interfaces B = Old technology, today we have moderns solution like VCS Fabric, VPC, MLAG, IP Fabric E = Buffer increase latency on network
why C. Could it cause latency?
