Hi all I tried google but haven't found an answer to my question. I just wanted to know if anyone has made good experience with m.2 SSDs only for ceph storage. I took a look at the pdf on this page where you guys tested ceph with 3 nodes and 4 SSDs each. There you use Samsung SM863 series. I...

Hi everyone I'm sorry that I'm asking this question in this forum, but I don't know where else I could get a answer to my question. I'm a newbie to FC HBA but we just got many servers from our clients that won't be used anymore. I wanted to build a SAN with 3 proxmox nodes. My questions are...

Thanks for the hint. I did actually filter for professional use by the shop, so I guess they got this in the wrong directory. Apart from that, do you think the rest would be worth the investment and speed should be fine?

Hi everyone I was thinking about expanding my 3 Proxmox nodes with CEPH. I had the following hardware in mind: 3* Icy Dock Tougharmor Mb998sp-b Drive Enclosure 3* IBM ServeRAID M1015 SAS/SATA Controller PCI Express 2.0 x8 IBM BULK 3* Generic Intel X520-DA2, Intel X520-DA2 Ethernet Server...

@mir thanks for the benchmark :) seems quiet ok! Will also take a look at that.

@brad_mssw thanks a lot for your hardware list! Very good tip on open vswitch, sounds very helpful and I will definatelly look into this subject. I didn't know about this.

Thanks a lot for your reply! I'm sorry I didn't respond earlier but I was just too busy this week. @nethfel I actually even tried ssds for journaling but it wasn't much better. Maybe I had the wrong ssd disks or did something wrong or didn't have enough osds (that I'm sure of ;) ). What kind of...

@udo I also have tested DRBD once, I just find it too much work compared to a shared storage that you can only mount ;) Why do you hate Supermicro boards? So far I only had good experience with them (apart from needing to update a bios because the new cpu wasnt yet suppored. But I didnt have an...

Hello everybody I've been using proxmox for a while now and I'm very happy with it. I've been using it with linux only and a freenas as a shared storage. I tested windows but it wasn't running good enough to actually use. I'm running Zimbra, bind, seafile, gameservers, teamspeak and apache...

Yes i also tested it with a local SATA2 drive. I reach around 30-43 MB/s copying a big file.

I'm writing from within the VM itself to it's own virtual harddrive. Because I'm using free NAS as a shared storage and have 3 nodes I'm doing everything over the network (if you look at it from that perspective). But essentially I just copy a big file locally onto the vm itself. I guess that is...

Hey Aristotlejones Good questions. I only have 16GB of RAM on my freenas. I am actually striping across mirrors. What do you mean by nice? If you meant NIC i have 2 on each node and 4total on my freenas (using only 2 atm). My switch is a Netgear ProSafe GS116E v2. I don't think jumbo frames...

I need to check that first. But I thought it was. Hmm that is a good point, I actually am using the shared one instead of a direct connection. I got 2 network cards per server, so I put them in failover. (NAS is on robin round though with 2 cards)

Hi nethfel Ok, maybe I should have pointed out that it's only on SATA drives either shared over a network or locally. With a RAID controller I also had extremely fast write speeds, but that was on SSD drives and also local. But at least on SATA drives you should get around 50-90MB/s. I find...

Nobody here ever had this problem :) ?

Yes you should use a shared storage on a separate server. You can most likely make an NFS share on Proxmox itself because it is a Debian, but don't do that. For learning it could be ok, but even then I wouldn't recommend it because you would want to learn what you can use later on. There is...

Hey all I tried so many settings with my Windows KVM and I can never get over 40MB/s. I don't know what I'm doing wrong. I'm using the newest virtio drivers, I tried the local disk and an NFS share on freenas. I have used SSDs on the freenas in a raid1 and I still can't get over 40MB/s. I tried...

Hello everyone So I have been testing HA with proxmox 3.3 and free nas and I am very happy with it. I have 3 nodes and 1 freenas. Because I always want to test more and find even better solutions (which sometimes isn't the best :P ) I thought about doing the following. Have 4 nodes and on each...

Ok I guess this is something to remember ;) Do you know how well this stop in HA works with Windows servers?

Your suggestion works :) Thanks a lot! I always thought Stop is pulling the power plug, so I never tried that. Instead it shutdown nicely. Does this also work for all Windows OS?
