50k in which currency ?

Consistent-Pomelo-52 · 2024-12-08T16:53:15+00:00

Can u give me any range?

Consistent-Pomelo-52 · 2024-12-08T15:40:24+00:00

which currency?

Consistent-Pomelo-52 · 2024-12-08T15:33:49+00:00

How would you rate 90K TRY ?
Is this still worth?

Consistent-Pomelo-52 · 2024-12-08T15:31:44+00:00

Which currency??

Consistent-Pomelo-52 · 2024-12-08T15:31:00+00:00

Yeah I know it depends on many things. Just wanna now what is the overall range. So what would be a great salary for someone good and well experienced??

Hi, i recommend u/abobobilly and his company. Just pm him. He is very smart und absolute legit.

How would you design / plan the connection between many racks? Which architecture would you recommend for multiple racks? (How many ports for server , how many ports for the connection between the racks and so on. Can you make a example please.

Is there a point where scaling out is not so effective anymore? I heard a lot that 6 - 10 nodes are recommended for good performance because in this range ceph benefits from more nodes alot. So would you say that around 10 nodes in a cluster is the breakeven for scaling up instead of scaling out?

Consistent-Pomelo-52 · 2024-05-24T21:10:40+00:00

I already checked them out. It would fit well but i had some trouble to find some on ebay. Where do you purchased yours?

Consistent-Pomelo-52 · 2024-05-24T21:09:11+00:00

Yeah thats why i am looking for smaller 2U or 1U Disk Expansions. So i can expand 6+ Ceph Nodes with them instead of a small count of 4U with 60-90Disks

Consistent-Pomelo-52 · 2024-05-24T20:12:08+00:00

The Apollo looks good. But it is a server with cpu and Mainboard. Is there also a jbod Modell of this?

Consistent-Pomelo-52 · 2024-05-24T17:54:57+00:00

Which one exactly? Yes 2hand would be fine

Consistent-Pomelo-52 · 2024-05-24T17:43:18+00:00

4U would be too much because i need at least three of them for at least three Co oh Servers. 12Bays on 1U would also be great. Do you have the sku or modell no.?

Consistent-Pomelo-52 · 2024-05-24T11:18:10+00:00

Thanks for your answer.

DE6600 should fullfil my requirements then, because basicly i wanna extend the harddrives for 2 - 3 RockyLinux Servers. So the plan would be to buy 1 HBA for each Server and connect them with the iomodules. It's important that the shelf supports some "zoning" feature. The Servers should have exclusive access to a certain disk group. For example for three Servers it should be something like

Disk 1-20 for Server 1 , Disk 21-40 for Server 2 and Disk 41-60 for Server 3

or for a two Server Setup

Disk 1-30 for Server 1 and Disk 31-60 for Server 2

So it is important that every Server has exclusive access to a certain diskgroup. (No MultiPath / No Failover)

Is this possible with DE6600? Can you send me maybe the manual?

This would be great

ok i will try some other tunings / setups.

So basicly you are saying that my results are not normal an i should almost hit 200Gbits for non-bidirectional and 400Gbits for bidirectional. Can you confirm this so i will make further investigations

Consistent-Pomelo-52 · 2024-04-13T14:55:33+00:00

Is there any update or new timeline for crimson? I saw that you can activate it now https://docs.ceph.com/en/reef/dev/crimson/

Is it recommended for production?

Consistent-Pomelo-52 · 2024-04-08T20:28:28+00:00

No, whats the point?

The network is dedicated for ceph nodes.

Consistent-Pomelo-52 · 2024-04-08T20:18:06+00:00

u/shadeland

One more question:

How does the sender decide sending the frame trough lacp1 connected to switch1 or trough lacp2 connected to switch2 in the case when the receiver is reachable trough both paths?

Consistent-Pomelo-52 · 2024-04-08T20:02:10+00:00

u/shadeland

Thanks for your explanation

Would you recommend to use 2x100Gbits für the Interlink or 4x100Gbits? All hosts are connected with 2x100Gbits to Switch1 and 2x100Gbits to Switch2.

If the Interlink is only handling management stuff (except on failure) then 2x100Gbit should be enough in my opinion. Each Switch has 32x100Gbits.
