The document discusses effective data management strategies focusing on duplication, provisioning, and virtualization in IBM storage systems. It highlights various RAID types, their benefits and drawbacks, as well as the advantages of thick provisioning and virtualization in optimizing storage utilization and facilitating efficient data redundancy. Additionally, it contrasts traditional storage management with virtualization, emphasizing enhanced performance and scalability.

The difference between Lazy Zeroed Disk and Eager Zero
Disk. The benefits & drawbacks of thick provisioning.

3. Types of RAID
Benefits
- Fast Read & Write
- Max Utilization
Drawbacks
- No Redundancy
or Duplication
Benefits
- Data can be recovered in
case of disk failure
- Fast Read Speeds
Drawbacks
- “Wasted” Storage
- Slow Write Speed
Benefits
- Efficient data redundancy
- Fast read speeds due to
stripping
Drawbacks
- Slow Write Speed
- Redundancy is lost if parity
disk fails

4. Benefits
- Same as RAID 4 Plus:
- Better write speed
- Better Redundancy
Drawbacks
- Can only handle a single
drive failure
Benefits
- Same as RAID 4 Plus:
- Can handle up to
two drive failures
- Better redundancy
Drawbacks
- Large parity overhead
Benefits
- Very fast performance
- Redundancy and fault
tolerance
Drawbacks
- Cost per unit memory is
high since the data is
mirrored

6. Virtualization
 Every device is an independent entity, physically and logically
 Underutilized storage resources
 Downtime caused by data migrations

 Break dependencies between end-user access and data

 Storage utilization is optimized
 Nondisruptive migrations
