Hp Smart Array P410i License Key
Sacha Weakland
I've not seen the case where a cache failure will flag an error on a RAID0 array. Check to see if the controller was set to continue to cache even if the battery failed - if that's the case, the RAID0 disk may have gotten a bad write. If not, it may be that the P410i has simply disabled access to the RAID0 in an overabundance of caution.
You would need to load up the HP Smart Storage Administrator to see the status of the RAID arrays on the server and get a better idea of what has happened. Although if the array was RAID 0 then a single drive failure would render all data lost.
I have installed ESXi 6 on it, and this usually goes quite OK. Sometimes i get to install a couple of virtual computers, but suddenly it tells me that the Drive status has failed (to a variable amount of disks), and the array has gone offline. I can go, take the disk out, and put it in again, and it works fine.
Consider adding the optional cache module to the HP P410, instead of leaving its cache extension slot empty. And if you use a cache module, don't forget to add an external battery to the SATA power, to preserve your data, if your system is not installed in a server room with UPS and power/temperature monitoring and alarms to stop your system reliably with enough time and power to safely terminate all your pending transactions.If you use it in home or standard business environements, power defects are quite frequent even if they are extremely short, but several seconds or a few minutes, and your data will be corrupted even if you used a RAID solution (software RAIDs in JBOD are now as reliable as "hardware" RAIDs in controlers, they are in fact more cost effective, but this requires an UPS for the host system too; JBOD works notably very well with OS-supported software RAID associating SASA/SATA hard drives from multiple controlers and a SSD and you're not limited to the number of controlers, but only by the speed of your motherboard PCI buses and bandwidth of the system memory; in addition the motherboard also has large amount of fast DDR RAM which also works as a first level cache for your SSD cache used as a secondary cache within your JBOD array controled by the software RAID driver of your OS, which now outperforms the software RAID drivers in controlers BIOSes, and offers better flexibility).
Personnally I think that today, almost all hardware RAID solutions are largely overpriced for what they are really made with and for their many limitations/bottlenecks and lack of flexibility/extensibility: you get much better performance by creating an external virtual NAS in a cloud connected by fast Gigabit Ethernel or fiber links, and you can easily extend the network to create an array as large as you want and to distribute the workload and tune the redundancy/backup as you want or redistribute it much easily when you need to replace any failing component.
If you want the ability to spin down the drives and access smart data, and have the ability to move them around "more" freely, then you need something like an h220 with the sas expander. This will allow you to access the drives JBOD vs. in a raid 0. If you only get the expander, then you're only creating more access ports for the P410i and it's raid configurations.
For those still trying to figure out a solution to the issue of using a P410i on a G7, I found the solution here: @terryjx/enable-it-mode-on-hp-smart-array-p410i-raid-card-on-hp-dl380-gen7-servers-4e827eeb78ca
thank you to everyone in this thread. i'm new to Unraid and purchased the pro. i'm also new to building servers as i'm coming from desktop environment. i have the DL380 G7 with its disc storage array partner that i want to hook up. i will have all my data on the array and then hook it to the server. i do however have 2 backplanes 8drives on each for a total 16 on the server itself i'd like to make use of, so i'm currently dealing with this JBOD issue in order to have Unraid do what its supposed to do.
people are saying go w/the H220/240 and a SAS expander to get the best performance and is the best solution. is this true because others are using LSI HBA to get the job done? i would think either way i need the sas expander for my situation. I am also understanding i would need to flash whatever controller card i get in order for it to work properly? if so, can someone point me in the right direction for the firmware i would need to flash maybe w/ a tutorial? im assuming i hook the sas expander directly to the controller once everything is setup and the drives to the internal ports on the sas expander and the array to the external ports on the controller.
I have a old HP proliant server with the HP Smart Array P410i controller. I have 2x 500GB SATA drives and 1x 1TB sata drive. Can I create a RAID5 array with these 3 drives? what will be my logical drive size?
