Drivers Areca SCSI & RAID Devices

Chapter 3, McBIOS RAID Manager. If you are using a Linux distribution for which there is not a com- piled driver available from Areca, you can copy the source from the SAS software CD or download the source from the Areca website and compile a new driver. Page 109: Driver Installation For Solaris. The Linux Kernel documentation¶. This is the top level of the kernel’s documentation tree. Kernel documentation, like the kernel itself, is very much a work in progress; that is especially true as we work to integrate our many scattered documents into a coherent whole.

Does anybody know a way to use an Areca 1882 with ESXi 7.0? Upgraden doesn't work you will receive an error:
[DependencyError]
VIB areca_bootbank_scsi-arcmsr_1.40.00.09-1OEM.550.0.0.1331820 requires vmkapi_2_2_0_0, but the requirement cannot be satisfied within the ImageProfile.
VIB areca_bootbank_scsi-arcmsr_1.40.00.09-1OEM.550.0.0.1331820 requires com.vmware.driverAPI-9.2.2.0, but the requirement cannot be satisfied within the ImageProfile.
Please refer to the log file for more details.
The easiest way would be for Areca to build a driver for ESXi 7.0, does anyone know if it is likely that Areca will create a driver for ESXi 7.0 for the 1882 series? Since Areca isn't the best when it comes to drivers, i kinda doubt it... Which is a shame really, The Broadcom 9361 (sort of the direct alternative for an 1882) has gotten a new driver within a couple of days after the release of ESXi 7.0.
Normally i would say i am really fond of Areca, but when it comes to drivers...

VMware

Today, more and more workloads are running in virtual machines (VMs), including workloads that require significantly more IO in the guest operating system. In a VM on VMware vSphere, all virtual disks (VMDKs) are attached to the LSI Logical SAS SCSI Adapter in the default configuration. This adapter is recognized by all operating systems without installing additional drivers, but does not always provide the best performance, especially when an SSD RAID or NVMe Storage is used. In this article we have compared the virtual storage controllers LSI Logical SAS, VMware Paravirtual and the NVMe Controller.

Controller models

The standard controller in almost every VM is the LSI Logical SAS SCSI controller. This controller is recognized and supported by every guest operating system without additional drivers. It is suitable for almost any workload that does not have large I/O requirements. It is also necessary for the configuration of Microsoft Server Cluster Service (MSCS).

Starting with ESXi 4.0 and virtual hardware version 7, the VMware Paravirtual controller is available. This controller was developed for high performance storage systems, because it can handle much higher I/O and reduces the CPU load. In order for the controller to be used by the guest operating system, the VMware Tools must be installed.

Starting with ESXi 6.5 and virtual hardware version 13, an NVMe controller can also be added to the VM. This controller further optimizes the performance of SSD RAIDs, NVMe and PMEM storage. This Controller is the default Controller for Windows VMs in vSphere 7.0.

The choice of the right controller depends on the applications within the VM. For example, if it is an office VM, relatively little performance is required and the standard LSI Logical SAS SCSI controller can be used. If more storage performance is required within the VM and the storage system behind it also offers more performance, the VMware Paravirtual Controller is usually more suitable. For absolute high end performance when using an SSD RAID, NVMe or PMEM storage and very high performance requirements within the VM, the NVMe controller is the best choice.

Performance test

We have conducted various performance tests for different scenarios. The test scenarios are only examples, the individual values should be adjusted individually to the own workload to achieve realistic results. Details of the test system used:

Hardware / Software:

  • Supermicro Mainboard X11DPi-NT
  • 2x Intel Xeon Gold 5222 (3.80GHz, 4-Core, 16.5MB)
  • 256GB ECC Registered (RDIMM) DDR4 2666 RAM 4 Rank
  • 3.2 TB Samsung SSD NVMe PCI-E 3.0 (PM1725b)
  • ESXi 6.7.0 Update 2 (Build 13981272)
