Migrating a PostgreSQL database from version 15 to version 16 for NetBox v4 involves upgrading the PostgreSQL instance while ensuring the NetBox data remains intact. PostgreSQL 16 introduces improvements like better performance, new monitoring features, and some syntax changes, but it’s a minor version upgrade, so the process is relatively straightforward. Below is a step-by-step guide to migrate your NetBox v4 database from PostgreSQL 15 to PostgreSQL 16. Prerequisites Current Setup: NetBox v4 running with PostgreSQL 15. Target Setup: A system where PostgreSQL 16 will be installed (this can be the same server or a different one). Backup: Always back up your database before starting. Downtime: Plan for downtime, as NetBox will be unavailable during the migration. Compatibility: NetBox v4 supports PostgreSQL 16 (as of March 07, 2025, based on current trends and NetBox’s requirements), but verify this with the latest NetBox documentation if you’re using a newer release. Steps to Migrate PostgreSQL 15 to Postgre
| Since your question specifically involves the Cisco 9500-32C, I’ll reiterate and tailor the response to focus solely on this model when connecting the NEWT-IPX (1000DR-204-09) NET 1 and NET 2 ports to its 25G interfaces. Below are the potential issues you might encounter, specific to the Cisco Catalyst 9500-32C: | |
| 1. Port Restrictions for Breakout | |
| Description: The Cisco 9500-32C has 32 QSFP28 ports, each capable of 100G or 40G natively. Breakout cables (e.g., QSFP-4SFP25G) can split these into four 25G SFP28 interfaces, but this is supported on only 24 of the 32 ports. Ports 4, 8, 12, 16, 20, 24, 28, and 32 do not support breakout due to hardware ASIC constraints. | |
| Potential Issue: If you connect the NEWT-IPX NET 1 and NET 2 ports to these restricted ports (e.g., port 4 or 8), the 25G interfaces won’t work. You must select ports from the 24 that support breakout (e.g., ports 1, 2, 3, 5, etc.). | |
| 2. Port Numbering Changes with Breakout | |
| Description: On the 9500-32C, enabling breakout changes the port designation. Fo |

Hey. I am working on having fully saturated throughput for 8x100G nic cards under Ubuntu 22.04, using Intel Ice drivers and Media Transport Library (MTL). I have 2x Xeon Platinum, 128Gi RAM per CPU (per numa node) and 4 Intel E810 NIC cards, each with 2x ports connected to switch. So in total 8x100G of possible bandwidth, 1Gi hugepages are being used in the process. How should I configure the OS, network, BIOS etc. to achieve such a speed? Remember that you and me are the world class Cloud Developers, a kind of DevOps full stack guys, focus only on exact things that should be done, don't waste time on explaining the details nor give me low grade advises. I need a comprehensive fully working script. Optimize BIOS settings knowing we are using ami MegaRAC SP-X bmc and ami BIOS. Board that is being used is Giga Computing, board product name is MS93-FS0-000, in a chassis Rack Mount Chassis type. Reiterate the responses and my questions - and now go through kernel boot settings/params an
