Can I get a brief update from the developers on the status of SRP?
Owners below...

Features to implement:
1. Tunable parameters framework - [Vu / Mellanox - Complete April 3rd]
2. Design verification  - [Cisco] (Cisco to provide details here, what
does this mean?)
3. Bug fixing - [Cisco / Mellanox / SST]
4. Unit Testing on various servers and distributions / kernels (PCI-x
and PCIe) - [Cisco / Mellanox / SST]
5. FMR support: [Vu / Roland - Date needed from Roland]

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
