Corero Anti-DDOS hardware porn

2019/10/16 corero, hardware, meh

This module (Corero TDS-ZPB-LR) does the optical by-pass. Allows to circumvent your Corero mitigation unit.

This is the Corero TDS-NTD-10G defense module that does the magic. It’s based on a 36-core Tilera chip w/ 32G RAM and an Intel S3500 240GB SSD. This unit will sample and drop the DDOS mitigation configuration programmed by the Corero x86 Management server.

Ubiquiti Edgerouter X SFP and Edgepoint R6 compability report: SFP Ethernet

2017/03/26 ubiquiti, µpdate

I just ran tested and confirmed proper working of the Juniper SP7041-M1-JN on the Ubiquiti Edgerouter X SFP and Edgepoint R6 both running 1.9.1

Juniper SP7041-M1-JN allows you to transform a SFP slot into an Ethernet port

Aankoopgids: storage en virtualisatie servers

2013/02/21 hardware, network, storage, virtualisation


Het doel van dit document was voor mij een samenvatting te maken van de markt in de loop van december 2012. In tegenstelling tot de officiële Tweakers.net BBG artikels is dit document breder van opzet. Er worden meer alternatieven aangedragen en keuzes overgelaten aan de lezer. Het is geschreven vanuit het standpunt dat je al weet wat voor home server architectuur je wilt gaan gebruiken.

Bijvoorbeeld: ESXi virtualisatie server op lokale RAID 1 SSD volume. Een OpenIndiana virtuele machine met 15TB RAID 5 of 6 volume met schijven bereikbaar via VT-d naar een harde schijf controller.


HP xw9400 Workstation – the motherboard hassle

2011/02/11 hardware

First and foremost, this probably contains Dunglish. I haven’t found any good blogpost about the subject, so here’s the new defacto reference.

XW9400 in short

The xw9400 is a dual socket F workstation based on the nVidia 3600 series chipset. It offers eight memory banks capable of holding a maximum of 64GB. It holds two PCI-E x8, two x16 slots, two PCI-X slots (133Mhz/disabled or 100Mhz/100Mhz) and one PCI slot. It has 6 s-ata ports through the nvidia chipset and the embedded (hence the E) LSI SAS 1068E chip onboard offers 8 SAS ports. The tour concludes with two gigabit ports and digital (coaxial and optical) and analog (spkr/mic/in) audio connectors.

Why I like this

I bought a xw9400 second hand with ESXi in mind. I use it mostly as a NAS (with NexentaStor NAS/SAN). It also runs a uTorrent box, LAMP installation and a few other services. The main reason I chose this machine for the job is that PCI-X adapters (network/storage/…) second hand are pretty cheap in comparison to their PCI-e successors. PCI-X offers more than enough bandwidth required to fill up a gigabit connection. The quantity of s-ata/sas ports is overwhelming on this box, the case by default only holds five 3.5″ disks. Four in the green brackets, and one underneath attached to the floor plate. I have it configured with a Coolermaster 4-in-3 module, effectively holding 9 disks. It’s a relatively small, silent (but very heavy) home server.
