Set up a VM on the Hyper-V hosts to serve the SMB share, that way your users doesn't need direct access to the Storewize and management is a lot easier, especially if you're running Active Directory in your environment. It's also easier if you at some point get more storage or more hosts to move the VM around if it's not statically bound to the specific ...

A real answer, though. Yes, there's a potential for latency or a performance hit from running your storage in a VT-d passthrough. But think about the practical aspects. Your system isn't going to be IOPS-bound in the first place. There are several levels of abstraction in this storage, and the fact that you're using VMs at all indicates that you're okay ...

1.You should size your workset to match the expected cache hit ratio. This totally depends on the workloads you are expecting. When you want to get a nice high number make sure that the workset completely fits into the cache. If you want the number for the drive which is like if there was no cache at all use the maximum possible size for the workset. For ...

I don't recommend this type of passthrough setup anymore. It's a lose-lose on most counts, especially with reliability and performance. It can certainly be done, but the safest solution (especially with a hypervisor like ESXi) is to just use a supported RAID controller and local storage. If you want ZFS storage, build a standalone ZFS storage system.

FC HBAs will auto-negotiate down 3 steps, so a 16Gb port can talk to another 16, an 8, or a 4. An 8Gb links can talk to another 8, a 4, or a 2. If you haven't changed anything on the switch, this should just work when you plug it in the first time. If it doesn't, you might need to log into the switch and fiddle with port settings. The Brocade command you'd ...

If the device /dev/cciss/c0d1 is degraded that's mean you have some hardware issue on the disks. The support need to check the ADU report and found out which disks reporting Read errors. If you have multiple disks with error and need to be replaced, support can make this storage node into repair mode, replace faulty disks, reconfigure the RAID and finally ...

We organize our databases by storage group on a drive. So SG1 is on G: and SG2 is on I:. We have multiple databases per storage group and thus per drive. We are running an all flash storage array so for us iops are not an issue. To your actual question I would say it is more likely a prefrence. By placing them on diffrent drives you can provide diffrent ...
