Listed below is a table to assist with the setup decisions during the configuration required to accomplish various tasks and goals.
Standard: a good starting point in regards to memory and CPU resources. This category is suited to handle the processing and caching with minimal requirements for network bandwidth.
Medium: good for workloads that are read intensive will benefit from the larger memory-based read cache for this category. The additional CPU will also provide better performance when deduplication, encryption, compression and/or RAID is enabled.
High: This category can be used for workloads that require a very high speed network connection due to the amount of data transferred over a network connection. In addition to the very high speed network, this level of instance gives you a lot more storage, CPU and memory capacity.
Required for kernel and system operations.
16 GB or more for best results
Paired with CPU by instance
1 GB per 1 TB of deduplicated storage.
Recommended for best performance
e.g.: 50 TB deduplicated storage = 50 additional GB for deduplication tables.
30 GB Hard disk for Linux boot and system disk (all EC2 instance types provide enough space to install and use SoftNAS Cloud®)
Elastic Block Storage (EBS) provides block data storage on Amazon EC2.
Recommended to configure EBS disks using SoftNAS software RAID for increased performance and data durability.
Up to 120 MB/sec
Small to Large instances provide up to 1GbE connectivity. Use High I/O instances to increase network throughput.
Not supported in Amazon EC2.
HA Host Failover
Configure multiple redundant SoftNAS Cloud® instances in separate availablity zones or different geographic regions.
CRITICAL: Do not use ephemeral disks for write logs. Ephemeral disks are local instance disks providing a much larger second-level read cache than RAM, and are typically more than twice as fast as standard EBS volumes. However, the data stored here is temporary and therefore lost upon each reboot.
Note: Refer to AWS for specific SSD performance metrics.
