Avamar ADS Gen4 Node Hardware
July 5, 2011With the release of the new Gen4 nodes, we can now take advantage of higher density disks and improved hardware configurations. There are 6 different type of nodes: Accelerator node, Utility node, 1.3TB, 2.6TB, 3.9TB and 7.8TB storage nodes.
All of the above node types now sport a single Quad Core Processor with the exception of the Accelerator node containing 2 Quad Core Processors, this is a step above the single processor in previous Gen models.
Disks are now configured in a RAID 1 configuration for increased performance. All node chassis’ are the R710 model with support up to 6 drives, except the 7.8TB node that has a R510 chassis which can support up to 12 drives.
A thing to note about the 7.8TB node, is the inclusion of a 100GB SSD for increased memory performance focusing on indexes. With the increased amount of disks and activity, this should keep the performance in line with the other nodes.
Here is a table with the different type of Nodes and their perspective hardware configuration:
| Nodes | Disk | RAM | CPU | Ethernet | Chassis | RAIN |
| 7.8TB | 12x2TB SATA 6x RAID 1 pairs |
32GB 100GB SSD |
1 | 4 | R510 | Yes |
| 3.9TB | 6x2TB SATA 3x RAID 1 pairs |
36GB | 1 | 4 | R710 | Yes |
| 2.6TB | 4x2TB SATA 2x RAID 1 pairs |
24GB | 1 | 4 | R710 | No |
| 1.3TB | 2x2TB SATA 1x RAID 1 pair |
12GB | 1 | 4 | R710 | No |
| Utility | 2x300GB SAS 1x RAID 1 pair |
12GB | 1 | 8 | R710 | - |
| Accelerator | 2x300GB SAS 1x RAID 1pair |
36GB | 2 | 4 | R710 | - |
Important Notes
* 1.3TB and 2.6TB are only available as Standalone nodes
** 1.2 Grids are no longer available
*** Minimum supported GEN4 RAIN Grid is a 1×3
**** Spare Nodes are no longer if Premium Support is purchased
