Home


Firewall Port Requirements:

  1. SSH and HTTPS 8080 REST API from Golden Copy to PowerScale IP pool in the System Zone.
  2. S3 port 443 https to target S3 storage.
  3. NFS access from Golden Copy and Virtual Accelerator Nodes to Systems zone IP pool
  4. Full firewall port table and directions can be found here.

Product Limitations and S3 Target Requirements

  1. Copying paths longer than 1001 characters due to REST API limitation on characters per request. This means files at folders below this level will not be copied to the S3 bucket the path is calculated /ifs/.snapshot/.... path to file and file name
  2. Number of folders configured for Incremental always scheduled concurrently is a maximum 30.  It is Not supported to exceed this concurrent folder incremental limit.
    1. In order to exceed 30 folders with incremental it is possible to offset additional folders to start on different hours to stay within the 30 concurrent limit.  example every 4 hours start 5 folder incremental and the next 4 hour interval start 5 different folders.
    2. Full copy concurrent testing limit of 5 folders
  3. Largest Tested file size of 100GB  files larger have not been tested.
  4. Directories with no files stored in them will not be copied to the object store as an empty directory.  The directory will not be visible in the object store.
  5. Characters supported in file and directory names as per AWS S3 specification listed here.
    1. Tested special character list for files and folders
      1. Safe Characters:  ~ ` ! @ # $ % ^ & () _ + - = [] {} : ; ' , . \ : * ? " < > | 
      2. Windows does not support these characters in file or folder names \ / : * ? " < > | 
      3. Azure does not support:   \ %  
    2. Not supported
      1. All other special characters not listed above
  6. Connecting to S3 targets on the Internet requires Golden Copy IP addresses to be NATed to the Internet. This applies to AWS and Azure or any other Internet S3 target.
  7. S3 Targets must support custom object properties for protecting meta data of the files and folders.
  8. Isilon or Powerscale any folder can be copied including snapshots.  In addition the DR cluster that is read-only due to synciq can also be used as a source of a folder copy.
  9. Recall  Cluster Targets
    1. Golden Copy Basic license 1 recall target configured at a one time.
    2. Golden Copy Advanced or Backup Bundle License recall target limit of 5 with the ability to select a target during a recall job creation
  10. Concurrent Jobs and Folder limits
    1. 30 folders defined
    2. 4 clusters added to Golden Copy instance
    3. 30 folders configured with a full schedule or incremental job type schedule
