[Oisf-users] 40GB inspection and I/O write speed concerns

I setup something like this.

You should be fine given you have SSDs.  I would recommend using the btrfs filesystem with lzop compression enabled, as the EVE JSON format compresses very well.

Subject: [Oisf-users] 40GB inspection and I/O write speed concerns

Hi All,

I am looking for advice. We are working on setting up a machine for potential 40GB a second on inspection. Our concern comes in the write speed of the I/O to disk as the meta-data that Suricata creates is important to us. Does anyone have experience with this? I have listed some of our set up below. Are there any suggestions or known issues that I should be aware of.

DL360 Gen 10
P408I-A (Raid Card)
4 x 2TB SSD in RAID 10 (Part number 877788-B21)
Mixed use SSDs
