Limitations, Requirements and Supported Target List

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.

Supported Browsers

  1. Windows Chrome, Edge (Chromium only)
    1. No browser plugs are supported if they interfere with UI functions, customers must disable them or contact the vendor for assitance.

Product Limitations and S3 Target Requirements

  1. Data copied to the bucket using tools other than Golden Copy will be recalled but metadata will not be recalled for this data.   The data must exist under the Golden Copy path in the bucket  <cluster name>/ifs/xxxxx   if the data is copied under this object path it will be recalled without metadata.  (Requires 1.1.6 or later)
  2. File Size differences when viewing files over S3 tools and Onefs using pipeline or backup and sync modes is normal.  Onefs Display application and logical size and S3 will display bytes only.    You can verify this with md5 checksum but it is common to see files copied or synced that will display different file sizes.  md5 checksum can be used to verify but it is normal and expected difference between onefs file system display of size vs S3.
  3. Active Directory resolution must be configured on Powerscale to resolve UID and GID, values on files.
  4. Symlink files are skipped and will not be copied
  5. hardlink files are copied
  6. Fast Incremental performance requires OneFs 8.2.1 or later releases.  The change list API includes metadata and removes the requirement to query the file system for metadata of the files in the change list.
    1. Releases before 8.2.1 do not support change list + metadata, this requires additional query to the file system for each file in the change list this will impact performance of processing a large change list of files.
    2. Solution is to upgrade to 8.2.1 of Onefs
  7. (Solved with unique long path support feature) 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.   NOTE:  Windows SMB path length limit is 260 characters.
    1. Golden copy Long path support feature.
  8. Concurrent Running jobs - Releases above 1.1.4 21073 or later
    1. NOTE:  More concurrent jobs does not mean increased throughput.  Copy resources are shared across all running jobs.
    2. Number of folders configured for Incremental always scheduled concurrently is a maximum 80.  It is Not supported to exceed this concurrent folder incremental limit, contact support.
    3. In order to exceed 80 folders with incremental it is possible to offset additional folders to start on different hours to stay within the 80 concurrent limit.  example every 4 hours start 5 folder incremental and the next 4 hour interval start 5 different folders.
    4. Full copy concurrent testing limit of 80 jobs but only 10 jobs execute at a time with resources shared across all jobs that are running. 
  9. Report creation is limited to 15 M success files but can be extended by adding disk to the vm to support exporting copy job reports in json format to any file count required by allocating more disk space for logging successful file copies.
  10. Concurrent running jobs display is limited to 10 active running jobs in the CLI any job submitted after 10 will not be displayed but it will be queued once one of the first 10 jobs completes,  queued jobs will appear as running.
  11. Largest Tested  single file multipart upload is 1TB  file.   No architectural limit blocks larger files other than the S3 target max object size.
  12. 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.
  13. ADS or Alternate data stream files will not have ADS streams copied
  14. Characters supported in file and directory names as per Amazon S3 specification listed here.

    1. Customers must review all limitations of any selected target including rate limiting, billing model. All Service providers rate limit and it is customers responsibility to contact the service provider for rate limits or quotas.   The compatibility below verifies API's used by Golden Copy product functionality has been tested. No performance guarantee can be made for any target. Any billing issues as a result of using any target below with Golden Copy is a customer responsibility.  All target errors that require investigation require the customer to have valid support with the provider and will be asked to open cases regarding target storage errors.
