3 1 Release Contents About This Release CTERA Cloud Attached Storage 5.0 (CTERA Cloud Gateways and CTERA Agents) includes the following highlights: VDI Mode Sync Gateway Mode Outlook Plug-in Single Sign On from CTERA Agent to a Portal Account Mac OS X Shell Extension Browse Previous File Versions Shell Extension CTERA Edit Cloud Gateway Network Troubleshooting Tools Notification on Predicted Drive Failure Notification If a Volume Selected for Cloud Backup is Offline SMART Disk Health Check VDI Mode CTERA Agent 5.0 includes VDI mode, which enables using the CTERA Agent with a virtual desktop infrastructure (VDI) in a Microsoft Windows environment and works with Active Directory. Enterprises and service providers who launch a virtual desktop as a service can leverage VDI mode in order to: Enable users to access data on their Cloud Drive from their virtual desktop. Decouple the user data storage and the actual system storage, as user data will be stored on the Cloud Drive rather than the VDI host. This enables one to: Maximize the number of VDI instances that can be hosted on a single host. Save on expensive, high-iops VDI host storage Cloud Attached Storage 5.0 Release Notes 3

4 1 Release Contents In order to enjoy these benefits, the enterprise or service provider must incorporate a CTERA Agent in VDI mode into the VDI desktop image. VDI mode works as follows: 1. VDI mode is enabled by applying a registry key to the target machine. For instructions, refer to the document "Using CTERA Agent in VDI Mode". 2. When a user accesses their virtual desktop, the CTERA Agent performs Single Sign On (SSO) and automatically signs on to the CTERA Portal with the user s credentials as listed in Active Directory. 3. Upon completing SSO, the user s Cloud Drive is mounted as a network drive called Cloud (Z:). If the drive is unavailable, the previous drive letter (for example, Y, X, etc) will be used. 4. The user can then access their personal and shared folders through the network drive. Tip It is possible to apply the registry key via Active Directory GPO, by upoloading the ctera-vdi.adm file to the group policy on Active Directory. This file is available from CTERA Support. Tip Single Sign On (SSO) works only in a portal environment configured with Active Directory. If these conditions are not met, the user will need to input their username and password Cloud Attached Storage 5.0 Release Notes

5 Release Contents 1 Sync Gateway Mode CTERA Cloud Storage Gateways now include Sync Gateway mode. This feature allows accessing the user s home and shared folders from other CTERA Cloud Gateways, for example a gateway at a branch office, while enforcing the permissions set in CTERA Portal. Here is how it works: 1. Enable Sync Gateway mode on the CTERA Cloud Gateway. Tip The CTERA Cloud Gateway must be connected to a virtual portal using an administrator account. 2. The CTERA Cloud Gateway s data synchronizes all the data in the team portal onto local storage, including all the user's home folders and shared folders, and exposes them to local users while preserving file permissions and the directory structure seen by each user. 3. The users access the cloud data from the following network destination: \\<MyCloudGateway>\cloud using standard network access over NAS protocols, such as: CIFS, NFS, and so on. Tip It is highly recommended to use Active Directory. Otherwise, using Sync Gateway requires the manual creation of local users with the same names as the cloud users. Sync Gateway mode offers many benefits in an office environment: Users can enjoy full LAN speed access to their data when they are in the branch office, using standard file sharing protocols. Furthermore, users retain full offline access to their data during Internet or cloud service outages. Users retain data access (using the same credentials) outside the office, via browser, mobile device, WebDAV network drive, and so on. Sync Gateway mode allows content distribution, so that files and folders can be uploaded to a centralized location (CTERA Portal) and then automatically synchronized to remote gateways that reside at the branch. Sync Gateway mode allows collaboration between users in different branch offices. Sync Gateway mode also accommodates user migration procedures, so that if users are migrated from one branch to another, or if they frequently travel between branches, their files and folders will follow them to the target branch Cloud Attached Storage 5.0 Release Notes 5

6 1 Release Contents Outlook Plug-in The Outlook Plug-in is a Microsoft Outlook plug-in that replaces standard attachments with public links. When a user attempts to attach one or more files to an thread, a download link can be embedded in the message body, and the attachments synchronized to the CTERA Portal. The recipient can then use the download link to view or download the files from CTERA Portal. The conditions for embedding a download link and synchronizing the attachments are configurable, as follows: Outlook Plug-in can always perform these actions, never perform these actions, or only perform these actions when the size of the attached files exceeds a certain threshold (in MB). The Outlook Plug-in can ask the user before performing these actions. The download link to the sent attachments automatically expires after a certain number of days, and shortly after, the files are removed from the portal s sent attachments folder Cloud Attached Storage 5.0 Release Notes

7 Release Contents 1 The main advantages of this feature are: Users can send large files as attachments. Commonly, exchange servers limit the size of an attachment. Less exchange server storage is required. Exchange server storage is commonly high-iops, and storing the attachments elsewhere (on the CTERA Portal) helps reduce the amount of storage required. You can define a threshold determining when a public link will be used and when a standard attachment will be sent. Unlike , your files are never sent in a non-encrypted format. If needed, you can delete or update files after they have been sent. Single Sign On from CTERA Agent to a Portal Account In CTERA Agent, when a user is redirected to the cloud to perform actions (for example, View Online, Restore, Invite Team Members, and so on), the user will not be prompted to enter their credentials. Instead, the user will be automatically authenticated and presented with the relevant page for the selected action. This feature is supported in multi-user mode and single-user mode. In single-user mode, SSO will be performed only for users with agent administration privileges Cloud Attached Storage 5.0 Release Notes 7

8 1 Release Contents Mac OS X Shell Extension The new CTERA Agent 5.0 provides shell extension support for Mac OS X, providing Mac users with: File and folder synchronization feedback via overlay icons in the finder Right-click options to quickly generate public links, invite team members to collaboration folders, browse previous file versions, browse or view files online, and more Cloud Attached Storage 5.0 Release Notes

You can use this feature to quickly view, download, or restore previous file versions as needed. You can also stay up to date on who performed changes to the file, in the event that you are working in collaboration with your colleagues. CTERA Edit CTERA Cloud Agent 5.0 automatically installs a browser plugin that enables users to easily edit files downloaded from the portal, and have the updated files uploaded automatically to the portal when they are saved. The flow is as follows: 1. The user accesses the CTERA Portal Web interface, select a file, and clicks Edit. 2. The file is downloaded from the portal and opened by the relevant local PC program. 3.
