Just wanted to bring your attention to the publishing of the
“SAP HANA Network Requirements” whitepaper, that can be found at: http://www.saphana.com/docs/DOC-4805
I’ve talked with some of you in the past in regards to:
- What is the needed throughput for certain LAN segments;
- What is the maximum latency admitted for synchronous replication;
- What network segmentation must be implemented for HANA Network Integration;
- Etc.
All of these and other questions are answered in this
whitepaper.
For me, some aspects within the document caught my
attention:
- Recommended to have a maximum of 1 ms round-trip in the network connecting two sites when intending to implement synchronous replication;
- Demand for the HANA Internal Network (for inter-node communication in a scale-out cluster) to deliver minimum of 2x9 GBit/s in full duplex;
- Recommendation to have up to 9 network segments (with the implied demand for server network ports) for performance and security reasons…
Well, if this is a topic of your interest, be sure to
reserve some quiet time to have a close look at this document as it is indeed
very detailed.
I believe there are some aspects I would argue against or
add something, but overall is a very good document for all that want to get
started on these topics.
Also remember that I keep an exhaustive list of relevant SAP
Technical Document to make it easier to you all to find what you are looking
for.
You can find that on my blog at: http://sapinfrastructureintegration.blogspot.com/p/reading-list-for-sap-hana.html
Have a great reading!
