After the live presentation, our presenters took questions from the audience. Read the full Q&A below!
How does the services director talk to the traffic manager?
Brocade: The Services Director uses the vTM REST API over SSH and MGMT interface.
How many instances can the Services Director assign capacities to?
Brocade: Theoretically unlimited. The number of instances is not software limited.
What is the latency requirement for Services Director to assign capacity to the vTM instances?
Brocade: When used purely for instance licensing, the Services Director needs network links with latency of 400ms or less to support scales up to 5,000 instances.
Can Services Director work with WAF and WCA ?
Brocade: Yes. WAF and WCA are add-ons on top of vTM, Services Director cannot manage them as standalones.
Is the ServerIron ADX going to be virtual?
Brocade: Yes, we already have a virtual ADX offering.
Do you do anything for SSL offload?
Brocade: The traffic manager is capable of SSL offload. The SSL offload (using high end cryptography engine) is usually much faster than standard web servers. We can also re-encrypt the packets to the backend services.
In the SSL offload, do you pull the originating client address through or just resend the frame as an intermediary?
Brocade: Full proxy; client address is NAT’d. However, one can add special header to the request on the vTM to retain the source IP all the way to the backend services.
