We create a RAID-0 volume with 5 disks. Each disk is capable of 1000 IOs Per Second (IOPS), and has a Mean Time To Failure (MTTF) of 5000 hours, Q1: What is the expected maximum IOPS for the volume? Q2: What is the expected MTTF for the volume? RAID 1 and 10: We create a RAID-1 volume. Each drive is capable of 4000 IOPS and has a MTTF of 500 hours. The Mean Time T Repair (MTTR) a failed disk is 1 hour. Q3: What is the expected maximum Read IOPS for the volume? Q4: What is the expected maximum Write IOPS for the volume? Q5: What is the expected MTTF for the volume? We create a RAID-10 volume with 10 drives. Each drive is capable of 500 IOPS and has a MTTF of 100 hours. The MTTR for one drive is 1 hour. Q6: What is the expected maximum Read IOPS for the volume? Q7: What is the expected maximum Write IOPS for the volume? Q8: What is the expected MTTF for the volume? RAID 3, 4, 5 We create a 10+1 drive RAID-3, -4 or -5 volume with drives capable of 5000 IOPS and 10000 hour MTTF. The MTTR is 2 hours. Q9: What is the expected maximum Read IOPS for the volume? Q10: What is the expected maximum Write IOPS for the volume? Q11: What is the space overhead for this volume (express as either fraction or \%)? Q12: What is the expected MTTF for the volume? RAID 6: (there wasn't a Menti slide for this) We create an 8+2 RAID-6 volume with drives capable of 5000 IOPS and 10000 hour MTTF. The MTTR is 2 hours. Q13: What is the space overhead for this volume (express as either fraction or \%)
