ESXi embedded (USB/SD) vs ESXi installable (disks)
Chris had a VMware media question:
*************************
I am wondering what are the relative advantages and disadvantages of using ESXi embedded (on USB stick or SD card) versus ESXi installable (installed on disk) on ProLIant blades.
Obviously a pair of disks + BBWC for the built in SmartArray controller cost real money. But I get flexibility of patching and have media redundancy (RAID0).
Any comments when one approach fits better than the other and generally what is the best practice today and why?
***********************************
Oliver joined the chat:
******************************
I think you already mentioned all relevant pros and cons.
USB/SD:
- cheaper
- no redundancy (can be covered by HA if you accept short service disruption but you may have inconsistent applications due to the crash)
hard disk:
- much more expensive
- proven redundancy
Performance is not relevant here. If you deploy ESXi on both media then patching is the same.
It would be wonderful to have USB/SD redundancy J … already discussed on the blade PDL which I have added to the thread.
*******************************
Ron also added his voice:
***************************
Also note that with hard drive based systems there are metrics in place to monitor the health of the drives.
With a flash device we do not get the same health monitoring capability.
*****************************
What do you think? Do you one over the other?

Re: ESXi embedded (USB/SD) vs ESXi installable (disks)
The Main difference b/t the ESXi Embedded and ESXi Installable
ESXi Embedded (USB/SD) : Image provided by the OEM like HP along with the HP CIM bundled and HP latest drivers
ESXi Installable : Image provided VMware itself and default CIM bundled and there will not be any specific drivers (for eg: HP flex 10 nic drivers) users need to doenload and install them manually.
I work for HPE
