Highpoint RR Web Raid Management

Recommended Posts

Thank you for your help. Your info basically confirms what I was speculating. Did not realize WD20EARS were native 4K, thought the only difference b/w them and WD20EARX was SATA 3GB vs 6GB. I thought they both emulated 512. Thanks jim

Oops - I might be mistaken - I do see references to 512B emulation for the WD20EARS and, like you, I thought up until a few hours ago SATA 6GB was the only difference.

 

I gues the outstanding question is whether these new drives are somehow different and that 512B is the only option they present or we're missing something.

 

A good discussion but not sure we're any further ahead :) Hopefully someone else chimes in or more data point reveal themselves...

It may just be the new web raid management interface. Eliminating options etc. jim

Alright, last post on this topic - I think we went down a rabbit hole on the 4K thing :(

Based on this thread it appears WD20EARS is doing the exact same emulated 512B thing as the WD20EARX (even indications they run the same firmware).

 

So, all things being equal, it's probably just the HighPoint WebGUI - arrgh.

PMFBI, but I suspect WD did the 512e because they had too many support issues with the EARS drives.

ikon thanks for your input. Any thoughts on the Highpoint WebGui. Not sure where the SHI features went.

Would that I could, but I've never owned a RR card. I tend to buy full-blown RAID cards rather than HBAs so I'm normally buying 3ware or LSI or Mylex. Haven't bought one in a few years though.

kcormier, I just finished building the array. I decided to delete it. I noticed if I now try to build the array it allows me to pick my sector size. I bet with the new webgui you do not have that seperate step to initialize the drives therefore unmasking the emulation. I rebootted the server and once again no sign of the drop down to change sector size. Not sure what I am going to do. Either just keep it a 512B after I build another array or immediately delete without rebooting and build an array with 4 k sectors. Any advice from the forum would be appreciated. Thanks jim

Thanks Jim - interesting - look like I might be rebuilding my array - or, maybe not - I guess I caught your last post before it was complete.

Yeah, I'm going to sit on my 512B array until someone else chimes in or I find some more data.

The smart setting is not in the new version (not sure why) so you did not miss anything. Most advanced format drives will default to 512B and you can only change it when you create it. That said, use the default as you will find that if you expand your array it will change it to 512B and you can not control that. It will then take twice as long to expand when it changes the sector size.
