I am about to buy a new server for our nonprofit organization. I need about 8 TB of storage. To reach this goal within the limits of my budget, I want to use 4 hard drives LFF SAS 4k 4To 7k2 in RAID10 on a Smartarray P408i. That gives me about 8 TB and some redundancy at an affordable price. 10k hard drives or SSDs are too expensive for my budget to 8TB. I have found a local reseller that sells the HPE ML350 gen10 server and it looks good to me. The only problem is:
- I need the model with 4xLFF hot-swappable bays, but it's only provided with the XEON Bronze 3106 processor, which, I'm afraid, will be too slow.
- If I want the best XEON silver 4110 processor, I automatically get the model with 8xSFF bays.
- My reseller does not sell the model that you can configure yourself.
I've looked at Supermicro because you can assemble them yourself. But I am blown away by all the possibilities and it will take me a lot of time to find the right system that way. In addition, they seem expensive compared to the ML series. I need a tower model because the 1U versions generate too much noise for my environment with their small fans running through the sound wall …
Now, the ML350 comes with a hot-swap backplane (8xSFF or 4xLFF), but it supports up to 3 backplanes. I could solve my problem by ordering the 8x SFF version with the XEON Silver processor, and order a additional hot-swappable 4x LFF backplate (874 566-B21). That would be great because I can use 4x LFF for my 8TB data, and 2x SFF for two SSDs for my OS (I will use VMware to host 3 OSses: Linux for an SMB file server with about 50 users, pfSense for a firewall and Linux for a digital signage server). If the built-in Smartarray P408i has two miniSAS connectors, one will go to the LFF backplane and the other (instead of two) to the SFF backplane. I would lose 4 of 8 SFF, but I'm fine.
If this is not possible, I could buy a ML30 gen10. It comes with an XEON E-2134 processor (4 cores, 2 wires / core), which has half of the XEON silver nets (8 cores, 2 wires / core), but with a much higher speed of threading unique (2640 vs. 1547 according to cpubenchmark .net). However, it only supports one physical processor, while the ML350 supports two. But honestly, I do not think of a scenario in which I would put any additional processor in this machine anyway. I do not plan to run 10 OSses on this thing … right?
1) Does anyone know if it is possible? So, a ML350 gen10 with a 4x LFF backplane and an 8x SFF backplane? HPE only mentions a 4x4x4 LFF and 8x8x8 SFF configuration. It does not mention whether they can be mixed or not …
2) Do I need SSDs for operating systems, or will my three operating system configurations work properly on RAID10 7k2 drives? I know this might be a subjective question, but maybe my question is is it sure there will be a significant degradation in the performance of my file server's functionality once all the systems are down. exploitation will have started. (That is, the number of operating points in an operating system after it is fully started and (how) this IO affects the speed at which I can access my data when the system operating and data are on the same disk (not the same volume).)
3) Does a file server and / or firewall use "a lot of low-speed threads", or rather "some high-speed threads"? It will work better on 8 1 GHz cores or 4 2 GHz cores (assuming that GHz is directly related to speed, to simplify things). In other words, would XEON money be better or worse than E-2134?
4) Do you have any ideas on the possibility of setting up a second processor later?
5) I can save another 300 € if I buy 4 SATA drives instead of SAS. Is it worth it, since these SAS HPE 7k2 4 TB drives will still be SAS servers close to the line?
If you are interested: My total budget is 5000 € max. 3k to 4k € is better 🙂
All the questions concern me, but number 1 is my main bottleneck at the moment. Any help is greatly appreciated. Thanks in advance!
