AWS EC2 System Requirements
SoftNAS Cloud® System Requirements
Listed below is a table to assist with the setup decisions during the configuration required to accomplish various tasks and goals.

|
Recommended
|
Configuration Note
|
|
Compute
|
|
|
General Purpose
|
M4.2xlarge
|
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.
|
|
High Performance
|
M4.4xlarge
|
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.
|
|
Extreme Performance
|
M4.10xlarge
|
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.
|
|
Memory
|
|
|
Base RAM
|
1GB
|
Required for kernel and system operations.
|
|
System RAM
|
8GB or more for best results
|
Paired with CPU by instance
|
|
Additional RAM
|
1 GB per 1 TB of deduplicated storage.
|
Recommended for best performance
|
|
e.g.: 50 TB deduplicated storage = 50 additional GB for deduplication tables.
|
|
Storage
|
|
|
Boot Disk
|
30 GB Hard disk for Linux boot and system disk (all EC2 instance types provide enough space to install and use SoftNAS Cloud®)
|
|
Data Disks
|
Elastic Block Storage (EBS) provides block data storage on Amazon EC2.
|
|
Software RAID
|
Recommended to configure EBS disks using SoftNAS software RAID for increased performance and data durability.
|
|
Networking
|
|
|
Up to 120 MB/sec
|
1 GbE
|
Small to Large instances provide up to 1GbE connectivity. Use High I/O instances to increase network throughput.
|
|
HA Networking
|
Not supported in Amazon EC2.
|
|
HA Host Failover
|
Configure multiple redundant SoftNAS Cloud® instances in separate availablity zones or different geographic regions.
|
Note: Refer to AWS for specific SSD performance metrics.
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.
