Building оn yоur newly gаined PоCSD knowledge (аnd noticing thаt many people have been flocking out of a formerly bird-themed social media site) you decide that it’s time to run your own little micro-social-media service - maybe it will catch on! With modularity and scalability in mind, you buy four servers: two of the servers (S1, S2) have public Internet addresses and handle RPC requests from your external users; while the other two servers (S3, S4) store all the social media posts from your users. You start simple, and enforce that posts are strings limited to text at most 140 characters in length; to support this, your servers S1 and S2 expose the following RPC calls to your Internet users, where: UserID:PostID is a unique UserID concatenated with a unique PostID, and both both IDs are 128-bit integers; text is the string to be posted; and status is a boolean that determines if the operation was successful]: RPC calls exposed by S1, S2 to the Internet: status=PUT(UserID:PostID, text)text=GET(UserID:PostID) You also start with a simple approach to distribute requests to your data servers: S3 stores all data for odd UserIDs, while S4 stores all data for even UserIDs. These two servers S3 and S4 don’t have public Internet IP addresses - they have private IP addresses. Internally, these data servers S3 and S4 also expose a PUT/GET interface through RPC calls, where you are free to specify what to use as a key and as a value: RPC calls exposed by S3, S4 to the private network: status=PUT(key, value)text=GET(key)
Suppоse yоu hаve just been hired tо design the storаge subsystem of а log-based server (i.e. like S3-L-ST in question 1) You have a budget to use N=7 hard disks (HDs), each with 10TB capacity, and are considering a few options: Option 1: Use only a single HD in your server, and keep the other 6 HDs in your drawer as spares for when the one disk goes bad Option 2: Use 6 HDs in a mirroring setup (RAID-1) in your server, and keep one disk in your drawer as a spare Option 3: Use ECC-based incremental redundancy (RAID-2), with 4 disks to store data and 3 disks to store ECC code, and none as spares Option 4: Use erasure-based coding (RAID-5), using 5 disks for data, 1 disk for parity, and one disk in your drawer as spare
