Setup new System on PI1LAP

Today I started setting up a new system. I still have an old system on the shelf
that I think is suitable for the purpose of a ax25 system.

It’s a Dell Vostro 220 Series/0P301D with Pentium(R) Dual-Core CPU E5200 @ 2.50GHz processor.
And 2Gb of memory.

Furthermore, I have chosen to use a sata raid controller. From Delock.
PCI Card > 4x internal SATA with RAID.
(RAID bus controller: Silicon Image, Inc. SiI 3114 [SATALink/SATARaid] Serial ATA Controller)
Data transit 150 MB/s <-> 1.5 Gbit/s

This card can be RAID 0/1, 0+1. I have chosen to use RAID 1 (mirroring).
This has the advantage that if I use 2 disks there can always be one piece that can go up in smoke,
and the system still continues to run without data loss. Now I can change the broken HD and rebuild the RAID array. All this without data loss. Only the system will know some downtime because a sata disk is not hot swappable. (in this system). And we have to rebuild the RAID array.

I still have 4 old 80Gb drives, but I’m a little bit hesitant because these drives have been running for hours/days/months already. So I think I buy some SSD discs. I have been testing this system with Debian Stretch, and it just running fine.

I have benchmark the old HDD’s… It doesn’t look good.

Using Fio to benchmark. Random read/write performance

This will create a 4 GB file, and perform 4KB reads and writes using a 75%/25% (ie 3 reads are performed for every 1 write) split within the file, with 64 operations running at a time. The 3:1 ratio is a rough approximation of your typical database.

iops, Input/Output Operations per Second, and that’s what it’s all about. But well, this system doesn`t get a full load… I’m curious about the test with SSD disk.

Update 🙂
Yes i’m dead…my girlfriend is going to kill me, I just ordered 3 ssd discs 😉
