Here’s a link to the full PDF details: Optimized solid-state drive performance with HP SSD Smart Path P420i Setup Walkthrough for VSAN

This process accelerates reads for all RAID levels and writes for RAID 0” HP SSD Smart Path technology allows I/O requests that meet certain requirements to bypass the normal I/O path involving firmware layers, and instead use an accelerated I/O operation called HP SSD Smart Path (seen in figure 1). “ HP SSD Smart Path improves the performance of select HP Smart Array Controllers in SSD-based HP ProLiant Gen8 servers. Here’s the description from the HP “Optimized solid-state drive performance with HP SSD Smart Path” Technical white paper: Finally, there’s an option to enable HP SSD Smart Path and enabling it can accelerate reads and writes. So, you can deselect all of the disks that will be used for VSAN, thus disabling Read cache for them. I recently discovered that you can also selectively pick and choose which disks to enable cache for. In the case of the HP P420i, you cannot disable the I/O Controller cache so VSAN recommends setting it to 100% Read which essentially disables Write cache. Also, when destaging write cache, we want to ensure that the writes are committed to disk and not in I/O Controller cache.

Since VSAN handles Read and Write caching at the software layer, there’s no need to do it at the hardware level. In general, VSAN recommends disabling Read and Write cache for any I/O Controller. OK, a little background/overview on I/O Controller guidance for VSAN.

To resolve, follow these directions to implement the correct driver: The value listed under AQLEN is the queue depth of the storage adapter.Run the esxtop command on the ESXi shell / SSH session.

Here’s how to check your hosts IO Controller (storage adapter) queue depth: The bug reduces the queue depth to 28, instead of 1020, causing poor performance in VSAN. Bear in mind, I am not an HP server hardware expert, so your comments are greatly appreciated.īefore I go too far, there is a bug in the HP async controller driver for the HP 420i that is included in the HP ESXi image. There are things I’ve discovered that might not be obvious but can help in the VSAN setup. Others are looking for guidance from VMware on how to configure for VSAN. I think I have to change the settings in NVRAM to enable the confiugration of the Smart Array, yet all my tries faild.I’ve been working with many customers over the last several months and found that many are very familiar with HP hardware and just know how to set things up. This server is brand new never used before -was stored on the client office- and I check and found that this model of servers comes with non battery Smart Array controller. I return back to the 146 GB SAS drives and the message just keeps appearing again. When using Rescan System, this error message appears:ģ47 The cache for Smart Array P410i Embedded Slot is not configured" "The operation has failed with an unknown error, please restart the application and attempt the operation again" Now, we replace the drives and begin the configuration with the hp DVD and begin when we reach the point that we want to save the configurations, an error message appears: I have got a brand new hp ProLiant D元80 G6 server with embedded smart array P410i controller, I got 146 GB SAS drives and wanted to change them with 300 GB SAS drives before installation.
