CIS 320 Pencil & Paper Homework 6: RAID Implementations We have 8 disks each with a capacity of 1 Terabyte which we plan to use for storage in a RAID array What will be the storage capacity of our system is we are using: RAID 0 RAID 1 RAID 5 RAID 6 Raid 50 with 2 raid 5 sets Raid 10 How many disks can fail without losing data if we are using Raid 0 Raid 1 Raid 5 Raid 6 Raid 50 with 2 raid 5 sets RAID 10 Which RAID type or types would you recommend in the following situations: Storage of database files and transaction logs for a crucial database where the primary server room is in an earthquake prone area. Storage of a large archive of pictures and videos that will not change, but where rapid reading of the files is critical. Storage of a large volume of files of varied types where there is a moderate amount of updating of the data where: The system will require 3 Terabytes of storage and we are planning to use 750 GB drives in our RAID array The system will require 6 Terabytes of storage and we are planning to use 500 GB drives in our RAID array Indicate the values of the missing bits. Assuming each row represents a set of corresponding blocks across the 4 disks and we are writing a block to 3 of the disks and parity data to the 4th with rotation of the disk writing the parity bit. Disk 3 died and we must reproduce its contents. Indicate The values required: Parity bits for 1st block __ __ __ __ Reconstructed data for block 2 __ __ __ __
