Use 2.5" disks for enterprise SAS workloads and 3.5" for bulk and high-capacity storage. You've answered your own question. Buy the right type of server for your anticipated workload. If you need high performance drives, optimize for that. If you need a lot of storage, then focus on that. Small-form-factor (2.5") disks are available in the following ...

It is a cost/performance vs capacity question. 2.5" HDD, at the same RPM/rotational delay, have a performance advantage versus their taller brother by the virtue of the smaller platter area. This in turn permit lower seek time (because the head had to travel a physically shorter distance). At the same time, this means that total platter area (read: ...

Oh my... What the heck are you trying to do?!? This is a bit of a square-peg in a round-hole issue. SCSI is not SATA or SAS. Your Dell server is a PowerEdge 1850, which featured parallel SCSI (Ultra-320 SCSI) drives. These disks connected to an 80-pin SCA connector on the drive cage backplane. SATA and Serial-Attached-SCSI (SAS) superseded the old ...

I would suggest using an D2600 unit instead of the MSA60, but it will technically work when cascaded from your MSA2324 unit. 6TB drives... 4TB disks are known to work in that enclosure, so the 6TB will likely work. I wouldn't use SATA for a JBOD expansion because (depending on your cabling choice) you'll lose the dual-port/dual-pathing that the SAN ...

I can't find an official confirmation for this sorry but I did find one for the MSA2324sa working with an MSA70 - which was the SFF version of the MSA60 - so I'd certainly place a small wager that it'll work and probably be supported. That said like ewwhite I also hate the idea of using non-HP disks in HP storage, you don't need to look far on this site to ...

There are products for this but they are converters not adapters so are higher priced. One example is: ARS-2320S Ultra320 SCSI-to-SATA II Hard Disk Drive non Hot SWAP As mentioned by others your server and old drive use the SCA 80 pin connector which pre-dates SATA/SAS and was used to provide hotplug support for SCSI drives.

Another consideration is power usage (which is often billed). While 2.5" use less power per drive than 3.5" drives, because they are not available at higher capacities they use more power per GB.

If I understand this correctly, you want to access the OOB Management interface on a server from a remote location - is that correct? I do this at a lot of clients sites, and I generally setup a VPN to their network router and then connect to the OOB management via that VPN (either production or management VLAN dependent on their setup). If the server OS is ...

Your company restriction excluding terminating a VPN on a dedicated device is not necessarily our problem. Other comments and answers have given you the best practice and standard approaches to this solution. It sounds like you have a political issue and aren't given the tools necessary to do your job. Are you sure you've made the right case and ...

As far as I understand the background of your question, you have 3 options to accomplish what you want: Use a IPMI - Card that supports some kind of VPN. For example, some of the DELL RAC Cards support openVPN or pptp (which is not good, anyway) Use a IPMI - Card with public IP (unsecure and dangerous!) Use a IPMI - Card and connect it directly to some ...

Of course it would be great if someone could give an answer which allows to fix your problem right away. But I fear, there is no obvious answer. But there might be some directions of attacking the problem not attempted yet: Under the hypothesis, that some of your machines sometimes show the behavior and others never do, one could conclude subtle hardware ...

I changed the following option in my *.vmx file: mem.hotadd = "FALSE" By default it is set to "TRUE". I've not seen any issues changing it... I don't have any CentOS VMs running on MS Hyper-V so, dig in and see what options are available to fix this issue.

No, this won't work. I don't know where you obtained this equipment or why its missing fans, but you're not using it as intended. HP servers don't post without the requisite set of fans. In this case, there are SIX fan slots. You need FIVE in order for the server to operate. Please see the maintenance guide for this server.

Why buy a physical server? Just get an Azure or AWS virtual machine and go with it. No upfront cost, no maintenance, you pay what you use, and you can scale performance up and down depending on your workload.
