Actually I don't have a VPN but a Partner Interconnect: I don't know if this may change something.
What I made in these days was working on the AIX-side: basically I focused on TCP performance/congestion window, modifying some parameters in the "no -a" (let me know if you need the output). After that, I made some scp transfers between AIX and Google GCP and I got a higher throughput (around 240 Mbit/s). Unfortunately in some of my attemps the throughput decreases very quickly, especially when I try sending larger files (around 1 or 2GB), and so I end up with my usual and previous 16 Mbit/s. In other attemps, instead, my speed connection keeps increasing (max 400 Mbit/s) or is stable.
Concerning the traceroute, I tried a traceroute toward the same Google GCP machine using many Linux on-premises but I didn't get any "fragmentation required" issue. On the other side, I always get the "fragmentation required" issue if I traceroute from an AIX.. I'm focusing on this issue because I feel like this problem is correlated to the low throughput one.
As a rule of thumb in doing calculations, what figure would you use in Mbytes/sec? I know the answer varies grealty on the topolgy of the network but I wonde what newteok engineers use a rough rule of thumb?
Many thanks. (1 Reply)
I have a 10Gbps network link connecting two machines A and B. I want to transfer 20GB data from A to B using TCP. With default setting, I can use 50% bandwidth. How to improve the throughput? Is there any way to make throughput as close to 10Gbps as possible? thanks~ :) (3 Replies)
Hi
I'm wondering what are the differences between SOLARIS, AIX and RHEL ?
I would like to know in which operating system is best for what kind of implementation ?
Why some companies use Solaris instead of e.g. AIX and etc. ?
thx for help. (1 Reply)
Hi,
I'm able to migrate UNIX users/groups from Solaris to AIX (with same password using 13-char encrypted password from shadow file) but no luck with RHEL 5 to AIX.
I see encrypted password in RHEL 5 is bit lengthier than 13-char. Is there any way to convert encrypted password such that same... (1 Reply)

I have started a new job which requires AIX admin skills, which I have, and RHEL skills. Does anyone have a cheat sheet that if I know how to solve the problem in AIX how would I do that in RHEL? I was an IBM pre-sales technical trying to keep sales guys honest - not possible. Any other links to... (5 Replies)
Greetings Experts,
We are migrating from AIX to RHEL Linux. I have created a script to verify and report the NULLs and SPACEs in the key columns and duplicates on key combination of "|" delimited set of big files. Following is the code that was successfully running in AIX.

We found out that the Spectrum Scale (GPFS) doesnt support mix nodes (AIX and RHEL) on direct attached storage.
Is there any other options besides NFS for mix O/S? Trying to avoid network type of shared filesystem which might end up high traffic on IO because we do run backup jobs on those... (0 Replies)
