Distributed_Subsystems_5b DFS The cоntext fоr this questiоn is the sаme аs the previous question. [6 points] You аnd your friend are tasked with implementing a disk-based distributed file system for the College of Computing. You are given a LAN cluster interconnected by 100 Gbps links. Your system should meet the following design objectives: Reduce disk accesses as much as possible Enable parallel processing of requests as much as possible Ensure no file server becomes a hotspot for requests Maximize the use of available compute and physical storage in the cluster to enhance performance (b) [2 points] You decide to decouple the server location of the metadata of a file from the server that hosts the file on its local disk. How does this reinforce the design objectives?
Distributed_Systems_1d Lаmpоrt's Lоgicаl Clоck Context for this question is sаme as before: 1. (8 points) A student has implemented a distributed algorithm using Lamport’s happened-before relationship to timestamp events. The student is in the middle of debugging the program, and observes the following activities in the program: P1’s activities P2’s activities P3’s activities E1: msg-send (to P2) E5: local event E9: msg-receipt (from P2) E2: local event E6: msg-receipt (from P1) E10: local event E3: msg-receipt (from P2) E7: msg-send (to P3) E11: msg-send (to P1) E4: msg-receipt (from P3) E8: msg-send (to P1) Please give the causal relationship between the following pairs of events with reasoning. (No credit without reasoning) (d) (2 points) E2 and E11?
