Storage Sync for VMware Installation


If you love Storage Sync, try Smart Cache, Egnyte's next-gen hybrid technology. Egnyte has been investing heavily in Smart Cache -- it combines the performance and scalability of Storage Sync with intelligent caching technology, single drive letter, global file locking, and much more. Learn more here.

Storage Sync syncs the files from your local storage device through your virtual machine to the cloud; this combines the power of fast local access in your office with sharing and mobile access from the cloud.

Below, you'll find different requirements, installation instructions, restrictions, and other vital information to keep in mind throughout the installation and setup process.

System Requirements

Please refer to the following VMware knowledge base article to find the system requirements for your VMware ESXi product. If you need help deciding what VMware product is right for you, you can visit their website to see a comparison of VMware offerings.

Memory Requirements

Below are Egnyte’s minimum memory requirements. The amount of RAM required for your system depends on the number of concurrent users accessing the device and the number of files synced with Egnyte. To ensure scalability, you should select hardware based on forecasts for both concurrent user and file growth.

 Storage Sync Limits  4GB RAM  8GB RAM 16GB RAM
Maximum Number of Mapped Users  1000  3000  5000
Concurrent Users Accessing the Share  Up to 50  Up to 100  Up to 250
Maximum Number of Files on Local Disk  Up to 10,000,000  Up to 10,000,000  Up to 10,000,000


These figures are approximations; sync times can vary greatly depending on factors like file size. Please contact us if you have any specific questions about the right storage configuration for your company's workload.

We are also able to implement a solution with multiple VMs in circumstances where your max files or concurrent user needs exceed the figures listed above.

Storage Sync Installation

Total Storage Considerations

There is a total storage maximum of 16TB per Storage Sync instance. We recommend deploying multiple Storage Sync VMs if you need to access more than 16TB of storage at a specific location.

Maximum Folder and File Size

Egnyte allows you to sync 50,000 files in any folder and up to 10 million files total between your device and the Cloud. Files in sub-folders do not count against the 50K file per folder limit, so not only can you have 50K files in each folder, but you can also have up to 50K files in each sub-folder. Also, you can sync files up to 10GB in size. With the continued development of our sync tools, both the maximum number of files and the file size will continue to increase. 

Mapping a Drive to Storage Sync

Once you've installed Storage Sync on your server and synchronized your data, individual users can map drives from their computer to Storage Sync. To do so, follow the directions below:

For PC users: Open My Computer, and click on menu item Tools > Map Network Drive. The folder name to be used is: \\Storage-Sync-IP-Address\ELC

For Mac users: Open Finder, and click on menu item Go > Connect To Server. The location to be used is: smb://Storage-Sync-IP-Address/ELC

Active Directory Requirements

You can configure Storage Sync to work with Active Directory. We have qualified Storage Sync to work against the following Active Directory versions:

  • Windows Server 2012 Active Directory
  • Windows Server 2012 R2 Active Directory
  • Windows Server 2016 Active Directory


Storage Sync is built to integrate seamlessly with your VMware device, but there are a few restrictions that our integration does not support. The following are not supported:

  • Open LDAP integration (only Active Directory integration is supported)
  • Use of AFP to access the share from on Mac OS (only CIFS/SMB is supported)
  • Synchronization of files from existing external shared folders (only files Egnyte/Storage Sync share will sync)

Only files transferred to the Egnyte share using a mapped network drive (SMB/CIFS) will synchronize. All files transferred to the share through other methods (e.g. from Storage Sync command-line console) will not be recognized by Storage Sync and will not be synced to the Cloud.

Changes you make to a file will only be synced once you close the file. This is usually not an issue for file types that are typically closed when editing is finished (like Word or Excel documents).

However, there are certain specialized application file types like those used in databases (Oracle databases, Mysql, SQL Server, Access DB), Exchange servers, and virtual machines (e.g., VMWare) which are left open for extended periods of time while changes are made. Egnyte is not currently able to sync changes to these file types while the files remain open, so use caution when storing them in a synced folder.
