ExOS 7.4 Release Notes

(Release Date: October 21st, 2015)

Supported upgrade versions:

•7.0.0, 7.0.1, 7.0.1u1, 7.0.2, 7.0.2u1, 7.0.3 and 7.0.3u1
•6.4.6, 6.4.7

Upgrade Path:

•The supported upgrade path from 6.x is to upgrade to 6.4.3 or later first. Then upgrade to 7.0.0.
•The upgrade from 6.4.3 may take longer than normal due to the database upgrade that takes place.
•v7.0.x will only accelerate with peers running 6.4.3 and later due to a change to the Exinda internal protocol
  • If you are installing v7.0.x into an x800 estate, the best approach is to upgrade your core box to 6.4.3 and then install v7 on one or more branch offices.
  • This allows all the existing appliances to accelerate to the core appliance and allows the v7 appliance(s) to accelerate to the core box running 6.4.3
•We are working on releasing new Virtual Appliance images with this version by default. In the meantime, please upgrade to 6.4.3 first and follow the upgrade path above described.


•2061, 3062, 4010, 4061, 4062, 6060, 6062, 8060, 8062, 10060, 10062, Virtual

Link to download the software image:
• 7.4 supports a new image format (with V2 in file name). This format is smaller than the previous format (v1). Only appliances currently running 7.0.1 and later are able to use the v2 format for upgrades. All appliances running 7.0.0 and earlier must use the v1 image format.

Note: if the installation of a v2 image appears to fail, please check the logs. It might be that your system only supports v1 images. This will be evident by the presence of the following log messages in the system log:

[writeimage.ERR]: *** Target root partition size is < 1.5G, only v1 images are supported
mgmtd[2163]: [mgmtd.WARNING]: Exit with code 2 from
mgmtd[2163]: [mgmtd.WARNING]: Image installation failure: *** Target root partition size is < 1.5G, only v1 images are supported#012

If this happens, please reboot your system once and try again. If it still persists, then please use the v1 image.

Major New Features:
  • Inbound QoS now working along with Accelerated and Edge Cache Traffic
o When a traffic is being accelerated on first pass (data not yet in disk), it now complies fully with Inbound policies.
o Second Passes (data already in disk), still flows at full LAN speed.
  • FQDN-Based Network Objects
o   Configuring Network Objects based on fully-qualified-domain-names avoids the need of manual reconfiguration of IP subnets when server changes its IP assignment
o   Only available via command line: The command to be used is:
                              exinda(config)# network-object <NAME> fqdn <fully-qualified-domain-name>
o   The appliance performs a DNS lookup to the configured DNS server to resolve the locally configured network object.

Bug Fixes and Minor Improvements: Known Issues:
  • [D-03974] Edge Cache process can trigger a condition that makes it reboot
  • [D-02086] Acceleration is not supported between sites that are separated by a Firewall/Router that is performing NAT overload.
  • [D-04861] Users are not able to access the WebUI with a username that starts with a zero “0”
  • [B-06114] Inbound QoS for HTTP traffic hitting the Edge Cache engine is controlled by the policy set for the Web application group or the HTTP application object
  • [D-04963] Users with “Monitor” only capabilities can start/stop the optimizer.
  • [D-06081] Some CA certificates are displayed as “Expired” (Configuration > System > Certificates > CA Certificates). This, however, will not affect the appliance performance.
  • [B-06115] APS values are normalized to 1024 bit of packet-size, so applications that use very small-size packets like Citrix and RDP are not recommended to be measured using our APS feature as the values will be much higher than the real ones.
  • [D-04981] A policy to ignore all traffic, can cause Web Traffic outage
  • [D-04111] Edge Cache does not work for YouTube in Chrome browser.  Work Around: Add “--use-spdy=off --use-system-ssl” to Chrome shortcut. For example: “C:\Program Files (x86)\Google\Chrome\Application\chrome.exe --use-spdy=off --use-system-ssl” For group policy of changing Chrome shortcut, please refer to
