CEPH Build - EPYC NVME Power Consumption

Hello,

I have been using 3108 RAID controllers with supermicro servers for a long time.
It works fine.

However, due to the increase in SSD performance, I was always aware that software RAID will probably be better in performance along with some filesystems such as ZFS having additional unique advantages.
So I am finally considering making the leap from hardware RAID to software RAID, especially since NVME drives from what I know don't even have hardware RAID support.

In the past when connecting many drives I noticed I have to setup each signle drive as a RAID 0 through the RAID card, which I think would decrease performance.

So I have to questions regarding best method to connect 24 SSDs for software RAID?

1.
What is the standard way of connecting 24 SATA SSDs to a storage server and use each drive individually and/or setup as software raid?
From what I know a RAID card such as 3108 is usually needed to connect so many drives to the mainboard.

2.
How does 24 nvme drives work in Storage servers that support it? Does mainboard have shared PCIe lanes that are connected with the nvme drives?

Thank you.

I am thinking to buy AMD EPYC 64 core Server
But I am confused in AMD EPYC 7702p vs 7702. Both spesification is same but price wise there is aprox 20% diffrent.
So my question is 7702 is good or bad? why it is cheaper?

I am thinking to buy this server. It is good? Please post your valuable feedback

Hi,

I need a dedicated server and I found the following configs which are at same price:

E3-1245v5, 32GB RAM, SoftRAID 2x4TB SATA
E3-1245v5 , 32GB RAM, SoftRAID 2x450 GB NVME

I need storage space but at the same time I cannot compromise much on the speed.
I know that NVMe will be faster but the question is how much slower the SATA will be from the NVMe ?

Will it be very slow or somewhat slow ? Please clarify.

Thanks.

When I see a dedi advertised with, say 4-6 nvme drives, are the drives likely to be individually hot swap-able1 or are they buried inside the chassis and attached to the mobo like desktop pc's?

Ask the provider, I know.....but I'd like to save time and know my chances beforehand as asking too much feel like trolling them.

Am I better off going the colo route for this requirement? I'll do it if I have to but I prefer the dedi route if possible.

(don't need that many drives)

We currently have:

3 servers in EU

specs for each:
CPU: 2x Xeon Silver 4114 CPU
RAM: 120 GB ram
10 Gbps unmetered dedicated (per server , total 30 Gbps)
22 x 2TB SSD PCI NVME - RAID 0

current cost - 4500$ per month for all 3.

We are looking for the exact same setup at another DC in Western Europe, DE,NL,UK would be ideal.
can compromise on CPU / RAM if it will help reaching this price, as its less relevant for our usage.

Thanks.

Hi All,

I need a server (to start with) where I can do solution demos and build acceptance platform to perform upgrades etc.
For example, say a hosting company wants to design a solution where they want to move into ceph and openstack . and want a demo of how it looks like and how it works .. those are built virtually .. so this server will host a lot of virtual machines .. like 3x controllers, 3x ceph mons, 4x ceph osd, 4x hypervisors , 1x storage, 1x router , 3x object storage etc .. . you get the idea..

I already have a few servers from a provider, but the prices are getting higher, so I am just checking out what I can get. (maybe I am paying more)

Requirements:

at least 24 threads .. the more the better .. but not more than 40 threads ( can be amd or intel ) 1x ssd disk for the OS (can be 480gb min) and 2x 1 TB nvme .. ( i do not need raid , this has no customer data) 128 gb of ram Unmanaged kvm/idrac access preferred . but not a necessity. OS to be installed is ubuntu-focal minimum with only ssh enabled via ssh-key Bandwidth -- 99% incoming -- imagine 20-30 virtual-machines doing apt-get every week or doing git clone from github every few-days as a part of their build .. .. the only ports open = ssh and https ( say 1-2 hours per month, when a public demo is required) ... IPs - one for the main server, 3-4 additional Location: Europe preferred, but US is also OK.

Please do not ask me for a budget. But feel free to post your recommendations.


Thanks.

I am looking for a dedicated server for plex which can do occasional HW transcoding.
I am looking for an unmanaged server
Processor: Intel Skylake or newer with iGPU
Disk: 512 - 1TB NVMe
RAM: 16GB+
Network: 1Gbps port with over 10TB - unlimited(preferred)
Location: US(preferred) or good peering to US
Currently looking at Hetzner EX42-NVME, so anything in that price range works for me.

Hi there,

Can people recommend premium dedicated server providers who take uptime seriously and offer IPMI, redundant power, private networks, EPYC Rome configurations with NVMe, etc?

We don't need uncapped public network interfaces -- 25TB total between all our servers is fine, but the private network needs to be 10G+.

We used to use SoftLayer before IBM bought them. We're currently hosted with a very premium provider in Chicago but we're not getting the service we used to get there.

OVH's latest "enterprise" dedicated configurations (HG) look pretty good but... has anyone used them? Is OVH decent?

Thanks!

Webnx has announce their servers wont be back for weeks. We dont have weeks.

Looking for these in the West Coast USA.

500TB storage server/s, nvme drives for cache, 1gbps (10gbps for a month if possible) unmetered incoming, 40gbps private networking (aggregate if on multiple storage servers)
15 x server with iGPU, 32gb Ram, 1tb ssd/nvme, 1gbps private network, 1gbps public with at least 40TB outgoing.

We require free private networking for all servers.
Looking for something close to the pricing of webnx.

<<snipped>>

Thanks.

I want some servers with large memory and at least two 1 TB nvme disk near East Coast. or Netherland
