GNR / Mestor Future Research Directions<br />
• GNR “ring” configuration –<br />
– Adaptation of Building Block Approach<br />
– Shared (Dual Ported) disks<br />
• Data managed by storage nodes<br />
– Overlapping cfg: ½ the nodes of std ctlrs<br />
• <strong>Storage</strong> node pairs to shared disks<br />
• Scale out to many storage nodes<br />
• Global namespace / Disk mgmt<br />
• Mestor<br />
– Non Shared disks approach / Network RAID<br />
• Data striped across storage nodes<br />
• <strong>Storage</strong> node to captive disks<br />
• Scale out to many storage nodes<br />
