Exinda Announces ExOS 6.3

Exinda Networks have announced the release of their latest code, version 6.3. This release has a number of enhancements, some of which are going to be very well received.

The full release notes are on Exinda’s support site, but the highlights are:

Acceleration and performance

  • SMB2 Acceleration
    • Ability to accelerate Microsoft SMB2 traffic.
  • SMB (CIFS) and SMB2 Acceleration Object Cache
    • Ability to store complete files in cache.
  • Content Pre-Population for SMB (CIFS), SMB2 and HTTP
    • Ability to pre-populate the SMB object cache and/or WAN memory cache by downloading files via CIFS or HTTP on demand or at a scheduled time interval. This is a much sought-after feature, as it allows administrators to ensure that the Exinda cache is “refreshed” at quiet times. So, for example, files from the data centre can be transmitted down to the branch office appliances over night, offering superior performance for users first thing in the morning.

Visbility, reporting and control

  • Time Savings Benefits Report
    • Demonstrate the amount of time acceleration of application traffic saved.
  • WAN Right-Size Reporting
    • Display the percentage of time applications or application groups fall within a configurable utilization level.
  • Asymmetric Route Detection and Alerting
    • Detection and alerting when network traffic is being routed asymmetrically. 
  • Layer 7 Subtype Matching
    • Ability to match on Layer 7 sub-type attributes, such as those application which are carried inside HTTP e.g. Dropbox, iTunes, etc
  • VC (Virtual Circuit) Level Connection Limiting
    • Ability to limit the number of TCP/UDP connections passing through a virtual circuit, with admission control.
  • New, improved and updated application definitions
    • Provides improved application visibility, greater understanding of the applications in use, and more opportunities for granular application control


  • Storage UI to manage HDD disk allocation
    • Allows the redistribution of disk resources between services. If you don’t use a particular Exinda service, you can now allocate it’s disc space to a server you do use.
  • ACL configuration for restricting Management Access
    • Restrict access to management services (telnet, ssh, http, https and snmp) to a specific set of IP addresses.
  • Log a TAC Case Directly from the Appliance UI
    • Allow the creation of support cases and the transmission of diagnostics information directly from the appliance.

Virtualisation Support

  • Not a lot is made of this in the release notes, but the ability to run Exinda within a virtual appliance is going to be of great interest to those managing data centre networks and wanting the convenience and resilience of having their WAN optimisation solution follow their virtual machines around the infrastructure. More will follow on this soon – suffice to say that we’ve tested it here and it behaves, well, just like the Exinda appliances you’re already used to.



  • ExOS 6.3 has some substantial changes and improvements, however this means that it will not be suitable for some legacy appliances and others may need memory upgrades.
  • The supported platforms are  2060, 2061, 4060, 4061, 5000, 6010, 6060, 7000, 8060, 10060, VMWare, Citrix Xen. Most significantly, if you have a 2000 or 4000 unit, you should not apply this update.
  • Those with a device with 2GB RAM should consider upgrading to 4GB to ensure best performance and avoid swapping RAM to disc
  • If you want to get the benefits from ExOS 6.3 but do not have suitable hardware, please contact us and we’ll help you get the best deal on an upgrade.
