1.	Dynamic add/remove target - It is almost done, will be ready
this week. 
2.	Backport to RH4 - I plan to finish it by end of next week.

	Folks,

	One update:

	- "Design Verification": This is the work that Cisco has been
doing to identify the features that are in and not in in the OpenIB SRP
implementation. Please see mail from Kamen with the text file that lists
all these features. We expect to continue this work, which will lead to
a roadmap of features for the upcoming releases. 

	Regards,
	-Pramod

	Folks,

	Please see the list below for the tasks that we envision need to
be completed for SRP in IBCG1.0. I also list below, the work that Cisco
is planning to do for this release. (The individuals, other than Roland,
working from Cisco are new to the code, and will be able to assist in
the areas mentioned for this release.)

	Please let us know which items your team will work on for the
first release and which targets you will be testing against. Items 2-4
will require multiple people's effort. 

	Please mail if there are any tasks missing to integrate into the
release (packaging work etc.)

	Development Tasks - Code Freeze April 7th:
	1. Tunable parameters framework
	2. Design verification  - [Cisco]
	3. Bug fixing - [Cisco]
	4. Unit Testing on various servers and distributions / kernels
(PCI-x and PCIe) - [Cisco]
	5. FMR support: [Vu / Roland]
	6. [Stretch goal] Dynamic add/remove target

	Targets:
	1. Cisco has Engenio storage
	2. AI: Cisco to get DataDirect IB-attached storage

	Testing Effort:
	1. Open Action Item: Test plan for negative testing - [Cisco]

	Regards,
	Pramod

	Folks,

	I think we have all converged on option b.

	The next step is to determine the specific tasks, owners and
timelines for delivery. I will send out a list for review and setup a
meeting on monday to close out these items.

	To address a couple of items that have been brought up in this
thread:

	Aviram - dynamic detection is not in option b. This feature is
highly desired, but the consensus on the last call was that this feature
would put us out of the april code freeze timeframe.

	Sujal - same goes for working with the sst and cisco gws.

	I'm OK with option B.  I have a fulltime person starting next
week or the week after with an initial focus on IBCG SRP.  But I'm not
sure how much he'll be able to contribute in this timeframe as it's a
new person and will have a learning curve.

	Hi all,

	We have to find a way to release SRP comprising of at least
option B on the April 30th release date.  Let us know how we can help.
With 3 companies applying resources on this critical ULP, I hope we can
make it happen.

	Subject: IBCG SRP Meeting - Minutes from 3/13

	Folks,

	Minutes from our IBCG-SRP discussion below. The next steps are
for each company to specify which of the three implementation options
below would be preferred. Please reply back with your preference. Once
we have consensus, we will meet next week to identify the specific
development tasks and the owners of each task.

	Implementation Options:

	A. SRP driver is technology preview (No new features, some
negative testing, date-driven)

	B. SRP driver is "add-on" for HPC only (negative testing on
single path, static configuration, minimal tunable parameters -
framework, no multipathing, no dynamic detection of targets, no support
for Cisco and SST FCGWs)

	C. SRP driver is "add-on" for HPC and Enterprise (extensive
negative testing, multipathing support, dynamic target detection,
support for SST and Cisco FCGWs)

	Mellanox / Vu:

	- FMR in: Patch already submitted (Provide evidence that FMR is
useful; Vu will talk to Roland)

	- Tunable parameters: Framework needed as well ad decide which
parameters in the first release

	- SRP bootup in InitRD: How to do this? Moderate work (2 weeks);
Why would you want to do this without BoIB-SRP support?

	- SRP detect added/removed targets in the fabric: Moderate work
(Is this in the low level driver?) (3-4 weeks for the SRP work.)

	- Testing with commercial multipathing drivers

	SilverStorm / Todd:

	- IBCG is not interoperable with SST FCGW (from user management
	perspective)

	- Configuration file is required on the host file for interop
with SST FCGW

	- Vu's list should be good for IB attached storage

	- Is it OK to rely on 3rd party packages for failover?

	Cisco / Kamen:

	- IBCG SRP driver interoperability status with Cisco FCGW is TBD
(Roland has done some basic tests)

	- Basic level of tunable parameters

	- Improve user level management

	- Negative testing needed

	Please mail with comments or questions.

	Regards,

	-Pramod
