I have a pure SSD RAID5 array with just 4 disks and even with the fast SSD, it doesn't do all that great for writes- not as well as a RAID10 setup with a a total of around 20 spinning disks, in fact. You need way more disks than that to get halfway good performance as well as total throughput and even on some of our SAS systems with 8 or more spinning disks, had to go to RAID10 to get good performance. RAID5 with just 3 disks is not going to give you good performance at all, in particular with SATA and especially with writes. I should have plenty of resources available to do other cool things. Later I will be adding VMs for other purposes hopefully, as I've spec'd this server to be overkill for a home surveillance server.
Right now I just want to get the server spun up, running my cameras. I'm also considering a setup like RAID 1 for the hypervisor / VMs on just 2x 300GB drives, leaving 4 bays for the surveillance array, so I could use RAID 10.Īm I going to run into performance issues running both RAID volumes on the same H700? I've been warned against this as it may be sub-optimal, but I can optimize the configuration with more hardware or more exotic RAID setups later.
So my plan now, after learning that the HCL isn't necessarily 100% inclusive of compatible hardware, is to use a RAID 5 array of 3x 300GB WD 2.5" SATA HDDs in first three hot swap bays for hypervisor and VMs, then on the same RAID card (in the other three hot swap bays) I'll have a RAID 5 array of 3x 3TB WD Purple 3.5" Surveillance SATA HDDs for the camera footage which will be recording 24/7, constantly writing over itself. Hardware Compatibility List results for Dell PERC storage controllers (SAS only, no SATA support): Thanks again folks if you are taking the time to read this and help a noob! Are folks doing camera footage RAIDs with SDDs now? I had bought the WD Purple HDDs because they are the recommended drive for storage of surveillance footage because they are designed to handle the abuse of 24/7 writes with high reliability.

When planning this build, I had imagined that eitherĪ: my hypervisor, VMs, and camera footage would all be stored on the same really large RAID volume, orī: Two arrays in the hotswap bay on the same RAID controller, one for hypervisor / VMs and one for camera footage, orĬ: Hotswap array is just for camera footage, install hypervisor and VMs on SSD or array of SSDs? Use two separate RAID controllers in the same server? Or M.2 NVME SSD in PCIe?īut now realizing the compatibility issues, and since I require a larger volume to store the footage than SAS is capable of, it would seem that I'll probably need to buy a NAS for my camera footage RAID and SAS drives for hypervisor RAID, unless there is some exotic solution that would make this all work without increasing the cost of the system? Is my understanding correct? And if so, should I use an array of SAS drives in my R710 hotswap bays for my hypervisor and VM installation disk, and then, say, a NAS RAID array for storage of my security camera footage? To rephrase: if the XenServer Hardware Compatibility List says both SATA and SAS are compatible with XenServer for a given RAID controller, then either type of HDD may be used for the XenServer installation volume, but if only SAS is compatible for a particular RAID controller, then XenServer must be installed on an array of only SAS drives? SAS compatibility with storage controllers in XenServer.this applies only to the disk where you install the hypervisor, correct? but XenServer would still be compatible with, for instance, reading data from an array of SATA drives on a NAS? 6x Dell (Seagate ES.2) 3TB 7.2k RPM 6Gb/s 3.5" SAS HDD - Just found these for $37ea on Amazon.***EDIT: I returned the three Western Digital Purple and Blue SATA HDDs after deciding that SAS HDD or any SSD would be preferable to SATA HDD if acquired cheaply enough.
Do I possibly want to consider a different RAID controller other than these two?
#Does dell perc h200 support ssd drives free#
might swap the H200 for an H700 RAID controller because I thought it was more powerful? and seller offered free "upgrade", but now I'm worried about compatibility more than specs.3x WD Purple 3TB 3.5" SATA Surveillance HDD ($$$).3x WD 300GB 2.5" SATA HDD (old, questionable reliability, but free).Dell R710 w/ 2x Xeon 5680 CPUs, 128GB ECC RAM (16x8GB), H200 RAID Controller, 6x 3.5" hotswap bays.I'm building a homelab PoE security camera server / general virtualization server, and I have the following hardware: Am I to understand that SATA HDDs are not compatible with XenServer using Dell's H700 or H200 RAID controllers? I need to know if SATA HDDs are compatible with XenServer 7.6CR when running in RAID on an H700 or H200 controller in a Dell R710 server.Īccording to XenServer's Hardware Compatibility List, the H700 and H200 only support SAS, not SATA. Homelab noob here, thanks in advance for your help!
