Microserver Gen8, B120i cache, BBU and ld extend

Hello.

 

I have MicroServer G8(712318-421), RAID B120i. And I have 2 question about it.

Now I use Hyper-V Server 2012 R2.

 

1. I changed the HDD to a larger. Now I want to change logical drive size. In SSA this functional not exists. In CLI (ctrl slot=0 ld 1 modify size=max) I get error:

Error: This operation is not supported with the current configuration. Use the
"show" command on devices to show additional details about the
configuration.
Reason: Transformation size zero. This may indicate that
there is no battery or a failed battery on the controller.

My controller configuration info:

Dynamic Smart Array B120i RAID in Slot 0 (Embedded)

As I understand, MicroServer has not BBU. Also it has not write cache memory(maybe I mistaken?).

In HP Dynamic Smart Array RAID Controller User Guide I see that B120i support optional 512 MB
FBWC module. But I don't see connector slot on Microserver motherboard.

In HP Microserver Gen8 QuickSpecs I see that "No FBWC support. For FBWC, a standup Smart Array Controller card
must be configured.". I don't understant - I need buy external RAID controller to have write cache?

 

Question #1: Is there any possibility to extend logical drive in my MicroServer G8, or I must only delete old logical drive and create new logical drive?

 

Question #2: In my configuration is absent optical drive, I think about installing SSD on this place. Is there any possibility to use this SSD as cache for B120i(on controller level)? May be I need to purchase some License for it?

The B120i does have the capability to support a cache module, unfortunately the MicroServer is not one of the systems that support the cache module as an option.

Thank you for your response. Yes, I thought so read the specification to the controller and MicrosServer. 

However, questions have been a little not about it - can I extend the logical drive(change size without delete old logical drive) using hp ssa[cli], and does I can configure controller to use SSD as a cache for the array (at least for read operations)?

no, the Smart Array cache module is part of the controller, no way to specify an external cache

You could move the drives over to the optional P222 controller

Re: Microserver Gen8, B120i cache, BBU and ld extend

This I already understand. :)

I lot of googling now and found this article: https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=SMARTCACHE-EVAL

HP SmartCache is supported on HP ProLiantGen8 servers with one of the following controllers: P420i, P420, P421, P822 and P721m. HP SmartCache is an included feature on the P822 and P721m/2G FBWC.

So answer on my Q2 - NO. And this can not but cause grief :(

 

How about Q1? Is it possible to extend logical drive without presence cache and BBU/FBWC? Even Synology DS411 can do this :(

Enough is not budgetary - half the cost of "chassis" even if buy controller on amazon.com, 500+ USD in RF :(
Plus, it takes a single expansion slot.

Probably have to transfer data to the new drives manually. Trifle, but not nice.

 

Thanks for your responses.

No, to do any expansion or migration a cache module is required.
