IBM XIV vs. EMC and Oracle/Sun disk systems: a closer look
| FEATURES | IBM XIV | EMC CLARiiON and Symmetrix | Sun/Oracle 6000, 99xxV |
|---|---|---|---|
| Virtualization | The system is inherently virtualized. This makes the system very easy to manage. | Capacity allocation requires awareness of system components such as disks, metavolumes, spares, tiers, and more. This makes system management more complex and time consuming. | Capacity allocation requires awareness of system components such as disks, 99xxV LUSE volumes, spares, tiers, and more. This makes system management more complex and time consuming. |
| Performance | All volumes are spread over all disks. Thus, all disks handle equal workloads, eliminating disk hot spots. | The system is susceptible to disk hot spots which can significantly degrade performance. Frequent manual tuning is often required. | The system is susceptible to disk hot spots which can significantly degrade performance. Frequent manual tuning is often required. |
| Rebuild time | Revolutionary protection scheme ensures 30-minute rebuild time (or less) for 1TB disks, minimizing the likelihood of a double disk failure. | Rebuild time can take hours, increasing the possibility of additional disk failures that can lead to data loss. | Rebuild time can take hours, increasing the possibility of additional disk failures that can lead to data loss. |
| Snapshots | Up to 16,000 snapshots in one system; no fixed per-volume limits. | Limited to far fewer snapshots. | Limited to far fewer snapshots. |
| Migration | Built-in capability; minimal disruption as XIV is inserted between hosts and the older disk systems being replaced. | No comparable capability in current system models | No comparable capability. |
| Costs | Hardware: Design innovations deliver high performance using lower-cost/high capacity disks. Software: Management software is included at no extra charge. Snapshots/clones, thin provisioning, and metro distance mirroring are all standard at no extra charge. |
Hardware: A larger number of disks and/or more costly, faster disks may be required to match XIV’s performance. Software: Management software is separately priced. Optional feature costs each have base charges, per-terabyte charges, additional charges when disk capacity is added to the system, and post-warranty maintenance charges. |
6xxx systems do not support thin provisioning. Both 6xxx and 99xxV offer key functionality only at extra cost, including support for snapshots, remote mirroring, data migration, and reporting. |
