Scale Computing S4 Clustered iSCSI SAN/NAS Storage Node

Scale Computing’s ICS architecture is the most versatile and easily scalable storage solution on the market. With a supercomputing core and low per TB cost, storage can be purchased as you need it, when you need it. Each StarterSAN begins with three Storage Nodes (SN) and can scale linearly, per TB. Choose your entry point with our 3 TBU, 6 TBU or 12 TBU ICS StarterSAN configurations.

Node Options:

Scale Storage Node S1:

• 1U Rackmount Unit, 2GB Cache, 1 2.0 GHz Processor, 2 Gigabit Ethernet Ports (copper).
• 4x500GB Drives (7200 RPM).
• 1TB Usable Storage Per Node with Required RAID 10.

Scale Storage Node S2:

• 1U Rackmount Unit, 2GB Cache, 1 2.0 GHz Processor, 2 Gigabit Ethernet Ports (copper).
• 4x1TB Drives (7200 RPM).
• 2TB Usable Storage Per Node with Required RAID 10.

Scale Storage Node S4:

• 1U Rackmount Unit, 2GB Cache, 1 2.0 GHz Processor, 2 Gigabit Ethernet Ports (copper).
• 4x2TB Drives (5400 RPM).
• 4TB Usable Storage Per Node with Required RAID 10.

Minimum Cluster Size: 3 Nodes

Technical Highlights

• Data Protection: All data is mirrored and striped across the nodes in the cluster
• High Availability: All data is mirrored on at least 2 nodes. This provides continuous uptime if a drive, network port, power supply or even an entire node stops working
• Scalability: Up to 512 Nodes per Cluster, more than 2.2PBs ina  single file system
• Compatibility: Nodes of different sizes can all participate in the same cluster (Limitation: 1 single node cannot be more than 50% of the total cluster capacity)

SAN - Storage Area Network Support

• SAN Protocols: iSCSI
• Max LUNs: 255
• Hosts Supported: Any standards-compliant iSCSI Initiator
• Security: IP based access control, CHAP Authentication, CRC based connection encryption
• High Availability: Connections supported to multiple nodes using iSCSI multi-path to connect to the same target/LUN

NAS - Network Attached Storage Support:

• NFS: IP/Host based access control
• CIFS: ADS Authentication (Kerberos)
• High Availability: Virtual IP Addresses are used to serve NAS protocols. In the case of a node/Ethernet failure another node will pick up the down IP and continue communication with the client without losing connectivity

Snapshots:

• System Snapshots: 31 (255 coming soon)
• User Snapshots: 4 (128 coming soon)
• Recovery: Any LUN/Share from any historical snapshot can be restored as a working copy

Replication:

• Efficiency: Copies changes at a block level (minimizing time and bandwidth)
• Consistency: Copies point in time snapshots to target cluster
• Recovery: Any LUN/Share from any available historical snapshot can be restored on the target cluster as a working copy
• Scheduling: Replication can be scheduled as continuous, or in 5 min, 10 min, 15 min, 30 min, 1 hour, 2 hour, 4 hour, 6 hour, 8 hour, 12 hour or daily intervals.
• Multi-site: Replication can be configured as a target or a source site for up to 15 other sites simultaneously.
• Management Interface: Serial Console and Flash-based Administrative GUI over https
• Notification Methods: Email, Syslog
• Support: Administrator controlled access to the cluster by Scale Support via SSH
• Upgrades: Upgrades are applied in a rolling fashion to maintain uptime by only removing a single box at a time from the cluster
