AWS Storage Gateway | Performance, Monitoring, and Maintenance Flashcards
What sort of encryption does tape gateway use to protect my data?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
All data transferred between the gateway and AWS storage is encrypted using SSL. By default, all data stored by tape gateway in S3 is encrypted server-side with Amazon S3-Managed Encryption Keys (SSE-S3).
What performance can I expect?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
Because the AWS Storage Gateway VM sits between your application and Amazon storage, the performance you experience depends upon a number of factors. These include the network bandwidth between your iSCSI initiator or NFS client and gateway, the speed and configuration of your underlying local disks, the configuration of your VM, the amount of local storage allocated to your gateway, and the bandwidth between your gateway and Amazon storage.
Our technical documentation provides guidance on how to optimize your environment setup for best performance.
What are the minimum hardware and software requirements for the AWS Storage Gateway?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
For these see the requirements section in the AWS Storage Gateway User Guide.
Can I use the AWS Storage Gateway with AWS Direct Connect?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
Yes, you can use AWS Direct Connect to increase throughput and reduce your network costs by establishing a dedicated network connection between your on-premises gateway and AWS. Note that the AWS Storage Gateway efficiently uses your Internet bandwidth to help speed up the upload of your on-premises application data to AWS.
Can I route my AWS Storage Gateway Internet traffic through a local proxy server?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
Yes. Volume and tape gateways support configuration of a Socket Secure version 5 (SOCKS5) proxy between your on-premises gateway and AWS. File gateways support configuration of an HyperText Transfer Protocol (HTTP) proxy.
What type of data reduction does AWS Storage Gateway perform?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
Volume and tape gateways perform compression of data in-transit and at-rest which can reduce both data transfer and storage charges. The AWS Storage Gateway only uploads data that has changed, minimizing the amount of data sent over the Internet.
Does the AWS Storage Gateway support bandwidth throttling?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
Yes, using the AWS Management Console you can restrict the bandwidth between your tape and volume gateway and AWS based on a rate that you provide. You can specify individual rates for inbound and outbound traffic.
How do I monitor my gateway?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
You can use Amazon CloudWatch to monitor the performance metrics for your gateway, giving you insight into storage, bandwidth, throughput, and latency. These metrics are accessible directly from CloudWatch; or by following links in the AWS Storage Gateway Console, which take you directly to the CloudWatch metrics for the resource being viewed. Please refer to the CloudWatch details and pricing pages for additional information.
How can I measure the cache performance of my gateway?
Performance, Monitoring, and Maintenance
AWS Storage Gateway | Storage
You can use Amazon CloudWatch metrics including CachePercentDirty, CacheHitPercent, CacheFree, and CachePercentUsed. These can be viewed by following the Monitoring link on the gateway details tab in the AWS Storage Gateway Console.
How can I measure the bandwidth used by my gateway?
