AWS Storage GW Flashcards
What is the AWS Storage GW?
It is primarily an on-prem virtual appliance device that acts as a gateway for s3 storage. It bridges traditional on-prem interfaces such as NFS, SMB, ISCSI volume and ISCSI tape with AWS S3 and Glacier.
What are the platforms Storage GW requires to run?
VMWare
HyperV
AWS instance (VM)
Is Storage GW good for On-Prem DR?
Yes you can use as a DR solution to keep data backed up.
What functions does Storage GW provide?
File Gateway for NFS and SMB
Volume Gateway stored mode, iscsi and async to s3
Volume Gateway Cache mode, primary data is on s3
Tape gateway virtual media gateway
I have some remote office with limited bandwidth and I wnat to provide this office with iscsi access to data, what options do i have?
Use Storage GW caches mode.
What are the storage interfaces provided for the Storage GW?
- VTL -> Glacier
- ISCSI (Cached) -> S3 standard and IA : Async
- ISCSI -> Snapshot (Backed up) to S3
- FileShare - S3
What protocols can the storage GW for file share support?
- SMB
- NFS
What protocol does Tape Gateway (VTL) support?
- ISCSI
What protocol does the Volume Gateway (ISCSI)? support
- ISCSI
What are the Storage Gateways 3 types?
- File Gateway
- Volume Gateway
- -Cached GW
- -Block gateway
- Tape Gateway
I have a set of tape drives that I currently use with ISCSI backup software, I wnat to modernise it, what can I use?
Replace the Tapes with Storage GW Tape GW. This will with existing ISCSI software and provide remote backup to Glacier.
When using the File GW, is the a 1:1 mapping of files, so I can see the files in S3?
Yes.
What is stored volume GW?
This is the volume gateway and is where you have all the volume capacity in the Storage GW on-prem and snapshots to s3.
What is cached volume?
This is the volume gateway, it is where the storage GW only stores some of the dat on-prem and reached out to s3 to get the rest.
Where is Tape Gateway stored in S3?
It is stored as a virtual tape shelf in glacier
For Tape Gateway, is it stored in S3 standard?
No, stored as a virtual tape shelf in glacier
How fast is it to get data back form Tape Gateway?
Slow, it is coming from a VTL in Glacier.
For a VTL what is the max size?
None, unlimited for the TVL but there is a 40 TB archive limit.
To do you ready your storage for storing in the VTL?
You create a ZIP a TAR.
I need hot storage, is VTL good for this?
No, TVL is archive storage, where data is stored in Glacier.
I wnat to get notified with VTL jobs get
There is an option on the Glacier storage in the VTL to get an SNS notification when jobs are complete.
Using a storage gateway, what is the Tape Storage interface?
It is an ISCSI tape interface, a traditional replacement for tape drives.
With regard to Storage Gateway, select the correct type of storage for long term archival where I was traditionally using ISCSI Tape?
Tape gateway.
I wnat to archive data to S3 and be able to access the S3 files from EBS directly, how cna I do this, what is the correct Storage Gateway storage and why?
File Gateway, File Gateway enables you to store data to S3 so you can access the files. This type of storage is NFS type files storage on the appliance side.
