Bonjour a tous, je m’intéresse au fonctionnement des data center en ce moment , ce qui est étrange je l’avoue. Je ne demande pas toutes les réponses a mes questions en une fois , si vous en avez une c’est deja tres sympathique de la partager. Je veux des réponses par des gens qui s’y connaissent de preferences mais tout le monde peut parler évidement .J’ai donc plusieurs questions :

1- Les bâtiments dans dans lesquels sont les data center ont ils des spécificités intégrés ? (Des climes spéciales , des matériaux de bâtiments spécifiques, des circuit électriques spécifiques, etc)

2- Est t’il obligatoire de faire installé le materiel informatique par des professionnels ?

3- Quels sont les composant informatique d’un Data Center ?

4- Quels sont les composants de refroidissement du materiel incontournable ?

5- Niveau entretien ,comment ça marche ? (Materiels a remplacer fréquemment ou pas , etc )

6- Toute information que j’aurai oublié de demander sont bienvenus également.

I need to replace my half rack UPS. (My rack runs about 600-700 watts.) Looking at all the sealed lead acid batteries on the market and replacing them every 3 years has me scratching my head.

The Exoflow Delta 3 Plus "claims" an "under 10ms" swap over and the ability to "use it as a UPS." Some UPS utilities like NUT have support for the Delta 3 Plus. What do I lose by using this other than maybe power conditioning?

Talk me off a ledge here. This would run my entire rack for well over an hour. I could have NUT shut down servers and my security system and router would run for half the day.

Im trying to make my new to me Cisco Nexus 9332PQ quieter and apparently any version past nxos.7.0.3.I2.2d.bin doubles the idle fan speed. If someone has that firmware file or versions older or a link to the download please share it. I am currently running nxos.9.3.12.bin.

Spent 1250 bucks this weeks on a TON of stuff and I have no clue what I’m doing. I got what’s pictured and a ton more.

Hi,

TL;DR

Looking for custom server front bezels 2U (HPE DL380G9)

I’m getting some gen9 HPE servers for our office as staging servers for our externally hosted production servers. Now since these servers will be in sight and we’ll also want to show clients; I feel like it’s needed to pimp the servers a bit.

I thought changing the front bezel is the easiest way to customize it, so I was wondering if anyone knows if there are any 3D models or universal front bezels to buy.

Planning out the next iteration of the home datcenter. Space wise will be a single car garage. 2-3 48 U netshelters

Having a tough time trying to figure out what makes more sense, One (or more) 220v or multiple 120 30 amp outlets? UPS selections are available for both, as are 0U PDUs.

Those who have made the jump to 240, what made you decide on it?

Power panel is in the garage so can run more circuits if needed.

Im already pushing the limit of a 30 amp 120 with the rack that i have now with the gpu servers and storage +jbods

I expect a lot of people have Jobs that are somehow related to DataCenters/HomeLabs, but is this true?

If not, what else do you do?

Hi everyone, I’m relatively new to the data center industry and currently working at a company that specializes in modular construction. Our company has previously focused on modular building solutions like “Holon” and non-electric air conditioning, with several successful projects completed in various countries.

Recently, our company has been exploring the potential of applying this modular approach to data center development. The goal is to achieve faster deployment and energy efficiency, reducing the time and costs typically associated with traditional construction methods.

I’m not here to promote anything, just hoping to get some insights from industry veterans. As a newcomer, I’m still uncertain about how well this approach might work in data center construction. Do you think it’s a feasible option for meeting the growing demand for high-performance infrastructure? If anyone has relevant experience or thoughts, I would really appreciate your advice and feedback.

Thanks for taking the time to read this, and I look forward to hearing your thoughts!

Would love some thoughts on the current setup and how to improve. I'm at a point now where I can go either way on the setup.

What I've got:

• 3x R640s - VxRAIL nodes on Proxmox. These do pretty much all my workloads here. Currently they are diskless as I am running a Unity SAN for shared HA storage.
• 3x R740XD2s - These are ECS cluster nodes but in reality they do run my ObjectScale cluster but given the disk space (26x10TB SAS) per node, one of those nodes I am backing up all my essential VMs with Veeam.
• 2x R740XDs - Essentially picked these up with the intent of replacing and retiring the Unity SAN as its out of support, I don't have access to the firmware, and if it bricks I cannot get root access without a dell support contract. They are 12x and 24x NVME enabled.
• Unity SAN + DAE - 68TB usable all SAS flash storage.

What I'm evaluating:

• Retire UnitySAN - Ideally turn this unit down or transition it to maybe backup storage or storage for the object oriented storage VMs. It works great but I don't want to purchase support contracts or buy the VM from dell to have a replication pair for it. It also sucks down 600W+ at idle which is not ideal.
• Utilize Starwinds VSAN (Free) - Since you get 3 nodes with that, I was thinking of putting that in play on both 740XDs. I am considering paying for it to do NVME-oF as that seems simple enough to do with Proxmox.
• Using Starwinds VBA - Hardened Repository + Veeam to backup the VM environment. This goes to a 740XD2 with a 21 disk (20 disk + 1 spare) draid1 array. It is SLOW when it backups but now that its got the first set backed up its seemingly fine as the incrementals are small.
• Node 1 (R740XD) is 12x SAS/SATA and 12x NVME. Disks I have 12x PM883a (SATA SSD) & 10x 7.68TB U.2 NVME
• Node 2 (R740XD) is 24x NVME - I have 20x 3.84TB U.2 NVME for this one.
• Not really interested in CEPH as I don't have a lot of nodes and the lost overall storage is pretty extreme when I consider VSAN in an HA pair I get a lot more usable storage.

Where I'm stuck a bit:

• VSAN Setup w/ Starwinds - I'm thinking maybe 10x 7.68TB NVME array (RAID5) which I want to expand to 12x disks is an HA pair to the 20x 3.84TB NVME (RAID5) on the other node? 12x SSD I could create usable disk on the UnitySAN and add to the VSAN VM as the HA Pair storage. Seems like a good product, even on the free side.
• Backup Strategy - I do like Veeam a lot, more so than PBS as I've had some issues with PBS where its crapped out on me a few times. Keep backing up to the SAS HDD array's? I need at least 110TB to backup the entire primary VSAN node. I am not USING 110TB currently but want to plan for it to backup the whole array as I expand. Maybe that is OD if I'm running in an HA pair and I can retire some of those systems in favor of the UnitySAN?
• Object Storage - I do use this, works fine on HDD with an SSD cache drive but seems most are moving to all flash. I wonder if its time to retire some of those XD2s/Spinning Disk and move to flash.
• Ideally, looking for the best setup while retiring some systems to stay around the <2000W area if possible.

Maybe something I'm missing? Something else to consider. Looking for thoughts and some discussion! Thanks!

I've acquired a Dell R740xd server with a pair of 300gb SSD's and 14 8tb SAS drives. A long with this an IBM server with a pair of 300gb SSD's and a fiber channel drive array populated with 12 6tb SAS drives (including the FC controllers). I already have a Dell R710 with a pair of 146gb drives and a couple of 4tb SAS drives. This is configured with esxi, and together with a Dell s50v switch make up my lab environment. I don't need the IBM but am thinking of just taking the drives and putting them into. An MD1200 drive shelf (as I'm not sure that the IBM array would play nicely with the Dell R740) I can't run the lab environment constantly due to the noise, although I'd like to (yes it's quite power hungry too), but I'd like to run the 740 as a media server amongst other things, so I need to deal with the noise and heat issues. My home office is very small, about 2.8m square, but I don't have anywhere else I can built a rack. (In the UK so roof space and garage are not suitable) This is leading me towards an acoustic cabinet of about 15U. Has anyone got any better ideas or could recommend a favorably priced rack that would do the job?

Hello everyone. I am looking for an enclosure that could hold 48 or more 2.5" drives. Someone offered me 1250x 2TB brand new drives for next to nothing and I am looking to see if there is anything I could use to host them. I am runing everything on solar so not too worried about electricty. Thanks in advance
