What is XCP?
The NetApp XCP Migration Tool is client software to enable fast and reliable any-to-NetApp and NetApp-to-NetApp data migration.
We've made XCP easy to obtain, deploy and use because in many environments XCP can turn data migration from a painful process into a performance showcase that helps customers save time and effort.
Fast NFS and SMB file-based data migration
With XCP you can fully utilize available CPU, network, and storage resources to scan, scope, copy and verify large file trees at maximum speed. With logging, reporting, subdirectory granularity plus three levels of verification (stats, structure and full data), XCP offers unique capabilities to accelerate and improve file tree processing and data migration.
Designed to handle volumes with millions of files
In the NFS world, traditional tools like rsync/find/dd/du use a simple back-and-forth style of serial IO operations so that when there are millions of files to process, waiting for all the round-trips to finish can take weeks. On the other hand, all the XCP features benefit from a built-in NFS client engine that generates parallel streams of asynchronous IO requests. XCP NFS engine significantly mitigates the effects of latency by keeping servers and networks busy all the time, making millions or even billions of files a lot easier to manage.
In the SMB version of XCP, we have implement the same parallelization algorithms to provide file discovery and transfer at maximum speed.
Scan - discovery and statistics of files and directories
Starting from any directory, XCP recursively reads all the subdirectories and can produce listings and reports in human-readable and machine-readable formats. Thanks to the matching and formating capabilities, the reports can be highly customized to match any reporting needs. Any file attribute such as the access time, owner, group, size, etc. are eligible criterias for filtering out the files in a report. Output formats include CSV, HTML or plain text listing.
Copy - fast parallelized file transfer
The baseline XCP copy transfers the files so that the target can exactly match the source, including hard links, symlinks, special file types, permissions, ownership, NTFS ACLs, and other attributes.
Sync – incremental updates to the target
XCP sync finds all the changes that happened on the source and then performs the necessary operations to update the target and make it exactly match the source.
Verify – thorough verification of target state
By default, XCP verify does a full comparison of target files and directories including NTFS ALCs, attributes and every byte of data, and has options for fast verification, selective verification, and incremental data verification after a sync to minimize cutover times.
Resume - continue an interrupted copy operation
Ran out of space or inodes? Encountered an unexpected error? Just fix the problem and resume your operations. On NFS there's a dedicated resume command to run, while the SMB operations just pick up natively from where it left off.
How do I get XCP?
Even though the NetApp XCP Migration Tool is free, it requires a license to work. Obtaining a license, installing and configuring XCP is a matter of minutes, and here are the steps:
- 1 Register a NetApp NSS account, if you don't have one yet
- 2 Download XCP NFS or XCP SMB to a host
- 3 Login and download a license
- 4 Deploy the license file to the XCP host
XCP Licenses are configurable to match your needs and environment. Standard licenses require the XCP host to be connected to the Internet so it can access the NetApp site for activation and license control. There's also the option to request offline licenses for closed environments that can't access the Internet. Standard licenses are instantly available, while offline licenses go through an approval process.
