I have 42 OSDs on 6 servers. I'm planning to double that this quarter by adding 6 more servers to get to 84 OSDs. I have 3 monitor VMs. Two of them are running on two different blades in the same chassis, but their networking is on different fabrics. The third one is on a blade in a different chas

Hi Jake, we have the fabric interconnects. MONs as VM? What setup do you have? and what cluster size? Regards . Götz Am 13.05.15 um 15:20 schrieb Jake Young: > I run my mons as VMs inside of UCS blade compute nodes. > > Do you use the fabric interconnects or the standalone blade chas

I run my mons as VMs inside of UCS blade compute nodes. Do you use the fabric interconnects or the standalone blade chassis? Jake On Wednesday, May 13, 2015, Götz Reinicke - IT Koordinator < goetz.reini...@filmakademie.de> wrote: > Hi Christian, > > currently we do get good discounts as an Univ

Hi Christian, currently we do get good discounts as an University and the bundles were worth it. The chassis do have multiple PSUs and n 10Gb Ports (40Gb is possible). The switch connection is redundant. Cuurrently we think of 10 SATA OSD nodes + x SSD Cache Pool Nodes and 5 MONs. For a start.

Hello, I'm not familiar with Cisco UCS gear (can you cite exact models?), but somehow the thought of buying compute gear from Cisco makes me think of having too much money or very steep discounts. ^o^ That said, I presume the chassis those blades are in have redundancy in terms of PSUs (we alway

Hi, we have some space in our two blade chassis, so I was thinking of the pros and cons of using some blades as MONs. I thought about five MONs. Pro: space saving in our rack Con: "just" two blade centers. Two points of failures. From the redundndency POV I'd go with standalone servers, but spac
