SteelHead-c models and required virtual machine resources
This section lists available SteelHead-c models, their supported maximum limits, and the minimum virtual machine resources required for each model.
Note: All CCX-SUB-PERF-TIER models must be manually deployed.
This table lists SteelHead-c models and their supported maximum limits.
SteelHead-c model | Optimized WAN capacity | Maximum # of connections
(all IaaS vendors) |
CCX-SUB-PERF-TIER1 | 10 Mbps | 1250 |
CCX-SUB-PERF-TIER2 | 50 Mbps | 4500 |
CCX-SUB-PERF-TIER3 | 200 Mbps | 9000 |
CCX-SUB-PERF-TIER4 | 500 Mbps | 1,000 |
CCX-SUB-PERF-TIER4-H | 500 Mbps | 30,000 |
CCX-SUB-PERF-TIER5 | 1 Gbps | 1,000 |
CCX-SUB-PERF-TIER5-H | 1 Gbps | 50,000 |
Each SteelHead-c instance requires at least two virtual disks. One disk stores the SteelHead-c configuration and management resources; the other disk serves as the data store. In AWS, virtual disk drives are referred to as Elastic Block Stores (EBS). Hard disk drives (HDDs), also known as magnetic drives, can be used for most models, but solid state drives (SSDs) can provide higher performance.
Note: We recommend SSD drives for CCX-SUB-PERF-TIER5 and CCX-SUB-PERF-TIER5-H models.
Note: All CCX-SUB-PERF-TIER models running in Azure require multiple disks, each disk not to exceed 300 GB.
This table lists SteelHead-c models and the disk capacities needed for each.
SteelHead-c model | Configuration and management
disk size | Data store disk size |
CCX-SUB-PERF-TIER1 | 38 GB | 430 GB |
CCX-SUB-PERF-TIER2 | 38 GB | 430 GB |
CCX-SUB-PERF-TIER3 | 40 GB | 430 GB |
CCX-SUB-PERF-TIER4 CCX-SUB-PERF-TIER4-H | 40 GB | 1 TB Azure:
4 x 300 GB (HDD) or 2 x 512 GB (SSD) |
CCX-SUB-PERF-TIER5 CCX-SUB-PERF-TIER5-H | 40 GB | 2.4 TB Azure:
8 x 300 GB (HDD) or 4 x 512 GB (SSD) |
This table lists SteelHead-c models and the minimum instance type, or minimum virtual machine CPU and RAM, required to run each.
Note: Amazon Web Services (AWS) is phasing out support for m1.small instances. New m1.small instance creation is no longer supported in certain geographic zones. CCX-255 model SteelHead-c virtual appliances continue to use m1.small instances because an adequate newer equivalent instance type is not currently available. Therefore, creating new CCX-255 model SteelHead-c virtual appliances or restarting previously existing CCX-255 model SteelHead-c virtual appliances is not supported in certain geographic zones. Contact support@riverbed.com for details.
