Hi Everyone, My name is Karthik. I am a first year graduate student in Embedded Systems at University of Pennsylvania. I am a avid c, c++ and python programmer.I have 4 years of work experience as Software developer at Airbus. I have been working as research assistant in PRECISE lab at the University of Pennsylvania to evaluate the performance of the Xen's RTDS scheduler. Currently, I am doing a course on distributed systems. As a part of that course ,I am building a small cloud platform using gRPC (Google's high performance , open-source RPC framework) with the following features: (1)Webmail service (SMTP & POP3) to send, receive and forward mails (2)A fault-tolerant backend server that employs key-Value store similar to Google's Bigtable. (3)The entire Bigtable is distributed across multiple backend servers. (4)Frontend Http server to process requests from a browser, retrieve appropriate data from the backend server and construct the http response for the GUI. (5)Storage service (Similar to Google Drive) with support for navigating the directories, folder creation and uploading and downloading any file type. (6)This system will be fault tolerant with quorum based causal replication done across multiple nodes and load balancing done with dynamic distribution of users among different groups. I compiled and hosted a small cluster to observe how ceph works in storing the data and how the distribution of the data is maintained while ensuring fault tolerance.With the help of my friend Myna (cc.ed), I could come to speed and performed few experiments to observe how data is shuffled after bringing down one osd. I am currently doing literature review on crush algorithm and understanding the Ceph Architecture. It would be exciting to work on project "ceph-mgr: Smarter Reweight-by-Utilization" Can you point me to any resources that guide to evaluate performace of storage system ? What kind of factors should one consider to evaluate performace of a storage system ? I could think of response time for reading, writing and deleting a file or how quickly a node is configured into a cluster or how quickly cluster heals after a node dies. Please suggest me some existing simple beginner bug which would give me a chance to explore the code. I'm very much interested in Ceph. I want to become a Ceph contributor in the near future. Thank you very much for your help!
