Hi,
I have 16 SAS disk on a LSI 9266-8i and 4 Intel 520 SSD on a HBA, the
node has dual 10G Ethernet. The clients are 4 nodes with dual 10GeB, as
test I use rados bench on each client. The aggregated write speed is
around 1,6GB/s with single replication.
In the first configuration, I had
Hi,
I tested a Arista 7150S-24, a HP5900 and in a few weeks I will get a
Mellanox MSX1016. ATM the Arista is may favourite.
For the dual 10GeB NICs I tested the Intel X520-DA2 and the Mellanox
ConnectX-3. My favourite is the Intel X520-DA2.

Hi Stefan,
deep buffers means latency spikes, you should go for fast switching
latency. The HP5900 has a latency of 1ms, the Arista and Mellanox of 250ns.
And I you should think at the price the HP5900 cost 3 times of the Mellanox.

Hi,
I *think* the HP is Broadcom based, the Arista is Fulcrum based, and I
don't know which chips Mellanox is using.
Our NOC tested both of them, an the Arista was the clear winner, at
least in our workload.
