Re: Ep45-ds5 & dq6

TEST0 - HOW MANY Maximum HardDisk Supported???
I don't find clear answers whether i found information (forum, docs, support ...)

SO, please, post information IF you heard from a direct source or test yourself the Gx Jmicron/Sis with 4 Sata2 in Raid0-Jbod
In fact the negative answer appear frequently

What i Suppose is:
What is Indubitable
1- The 2 Sis Connected directly to Jmicron can support 4 sata Jbod
2- Jmicron is able to manage 4 Device if we refer to the Specs

BUT, HERE IS probably the ISSUE
- In this page JMicron/Products http://www.jmicron.com/PDF/JMB363/JMB363.pdf

What is the difference ??

- 1st case we suppose that Jmicron handle 4 Sata PLUS the Pata, So 6 device??
- 2nd case - Jmicron handle 4 Device TOTAL, 2 Pata & 2 Sata If Pata is active and that's the case for Bios

If that analysis is correct, maybe

Gigabyte knows that from the start, but why their fuzzy explanation and bios features?
more probably - they discover that during the writing process of Bios, which can explain why they come back to simple solution of "Smart backup"

In this case, It's Weird, because it was possible to have another Chipset than Jmicron or attach the Sis directly to the Ich10

If correct - Definitely we get Only and a Max of 2 SataII manageable by Jmicron and either
- 2 Disk -> so 2 Jbod0
- 4 Disk -> so 2 Raid1

This Gigabyte configuration Seems better for configuration like:

2*1T (max disk capacity) for server - Option- Incorporate Raid1 whith good perf (because sync between is assume by Sis chipset)
eSata because The 6-ICH10 are fulfilled
Nested/cascading with external Case - Neither that analysis, Sis features whith nested chipset is always potentially possible with other Raid mode than 0-1

Like Here, but here are prototype with Usb

I Agree also with Mv2devnull http://forums.tweaktown.com/256717-post9.html

Steelvine Cascading is really possible ??
I search for "External box" "external hard disk/drive" with Steelvine compliance and Sata connector - but didn't find any
These special Boxes require "Esata In" and "eSata-Usb Out" .. and incorporate one of the Sil75xx chipset family Steelvine .... Concerning our case Usb is not implemented in Gigabyte Motherboard for the Sil5723

I grabed this post : XtremeSystems Forums - View Single Post - Dedicated Gigabyte EP45-DQ6 thread

I have bought the board about 2 weeks ago. One reason for chosing the board was presence of 10 SATA channels onboard. This would suit my purpose: building linux-based home file server (raid6 etc).
However, I was disappointed quickly, having found no way to use the 4 SATA channels attached to GSATA independently. The Silicon Image 5723s -- used as 1-to-2 port multipliers on each of GSATA's (aka JMicron 363) SATA ports -- support a bunch of RAID modes (RAID1, RAID0, combination of the two, and JBOD) according to Silicon's website. I was planning to put them in JBOD mode, and let the linux raid functionality take care of the rest. However, this is not possible right now. Gigabyte has decided that RAID1 is that we all need, and hard-wired the 5723s into RAID1 mode.

I have had conversation with Gigabyte support techs regarding this, and their reply was quick and disappointial: "(SiI5723 RAID chip) supports RAID 1 mode only. When you connnect four SATA HDDs, GSATA controller chip will able to connect them with RAID 0 mode."
Well, RAID0 consisting of 2 RAID1s was not what I was looking forward to when buying the board, although I understand there are users who find it useful.

I would venture into "un-hard-wiring" the 5723s to allow them to be used in any mode configurable with SteelVine Manager. This could probably be achieved by unsoldering some of 5723s' pins and reconfiguring the chips into soft-config mode. Unfortunately, so far I have not found which are the configuration pins. Apparently, obtaining the datasheet from Silicon Image would require an agreement to their NDA. I would appreciate any help in this field... [Update: I _have_ contacted Silicon Image for the datasheet, and indeed, I was asked to begin the NDA process. When it turned out that I am the single individual (end user) and not a manufacturer, I was politely but definitely informed that they disclose that kind of information only to manufacturers. Anyone out there being a manufacturer that would qualify?]

Conclusion: Unless you really want RAID1s, this board has effectively only 8 SATA channels.

After lots of playing around, I was actually able to create a RAID0 with only 2 drives connected to the GSATA ports (with F6 bios). Use port 1 and port 4. Completely un-intuitive I know, but I managed to do it. Mind you, I ended up not running with that in the end. I ran my RAID0 from the ICH10. The other thing that wasn't (and still isn't as of F6, maybe later bios addresses this) clear is that the the smart backup (RAID1 on the GSATA) found the two drives and is functional (it just says initializing, and then on the GSATA bios screen, its says non-raid, which to me, it really is, just not configured manually). The only way I proved to myself it was working was to put the two drives separately into another machine and see if they were the same (which they were).

TEST2- ESATA Cascading To Expand Capacity
If we connect on Sis Sata connector an external Box within Sisxx inside, can we manage a cascading configuration??

Thanks - i post here after have seen others ...

Q??
- Did you test the software "steelvine Manager?"
- Are 4 disk connected to G0-G1-G2-G3 appear as 4 Device (whith Bios Disabled settings) ??

**mv2devnull** · 08-19-2008, 03:30 PM

Re: Ep45-ds5 & dq6

Yes, I did try SteelVine Manager. It will show the 5723 controller that has disks connected to it if the SmartBackup function is enabled for that 5723 chip (ports). The array is naturally in SAFE mode. The array did rebuild and then verify, and there are options to start and abort rebuild&verify. Now one of the two disks I had, had read errors, and after verify, the controller started another rebuild and that cycle continued. There is no chance to change the mode of the array from the Manager.

If the SmartBackup is disabled, no "disk" is seen by BIOS nor OS, and Manager does not see the 5723 chip(s) either. With the F5 bios something was seen with SmartBackup disabled, but no more with F10a.

Re: Ep45-ds5 & dq6

WOW, Great info here. So it seems maybe users should use the older BIOS's or is this just all still up in experiment land?

**mv2devnull** · 08-20-2008, 01:44 AM

Re: Ep45-ds5 & dq6

Still in the experiment land.

IIRC, I did try "disable SmartBackup" after it had been enabled and the F5 bios (or more precisely the GSATA jmb363 thingy) saw a "500 GB" drive (while the chip had two 500 GB disks connected). Ie, it did not revert to the "1000 GB" drive that I saw on first connect, before enabling the SmartBackup for the first time, nor did it show two disks.

**mccann73** · 08-20-2008, 07:20 AM

Re: Ep45-ds5 & dq6

There is some great info here, and from my quick read of this thread, in theory the combination of the Jbmicron 363 and the 2 SiI5723 controllers should give us more options that just RAID 1?

I logged a support call with Gigabyte and here is the answer, it would be disappointing if they do nothing more with this controller(s), and I would have to say there is some false advertising as the raid controller was originally advertised to support both raid 1 and 0 modes...

============
Dear Sir,

Thank you for your kindly mail and inquiry. About the issue you mentioned, according to the latest BIOS design, the GSATA2 SATA controller support Smart Backup feature, this feature allows the system to create the RAID1 environment automatically without using the traditional RAID BIOS, that's why you won't see the GSATA RAID BIOS menu anymore. And because currently GSATA2 SATA controller only support Smart Backup feature (after F7 BIOS), this will automatically enable the RAID1 with the HDDs which connected to GS0-Source and GS1 (or GS2-Source and GS3) SATA ports, so it does not support RAID0 environment.

At last, if you still have any further question or suggestion about our products/service, please do not hesitate to contact with us. We will try our best to help you resolve the problem ASAP.

Regards,
GIGABYTE TECHNOLOGY

Re: Ep45-ds5 & dq6

Nothing really surprising or novel in that.

I do have printed manual of GA-EP45-DQ6. Revision 1001. Its chapter 2, Bios Setup, apparently does show BIOS rev F2a. Probably something that has never seen retail. Within its options, there are two entries, "SiI 5723-1 GSATA 0,1 Ctrl" and "SiI 5723-2 GSATA 0,1 Ctrl". Each of them would have had five possible values: SPAN, JBOD, FAST, SAFE, and GUI. Of them, GUI would have let an application, "GIGABYTE Smart Backup tool" to choose the mode of 5723. My board came with F5 BIOS, which has no such things, and the later BIOS seem even more terse.

There are now two possibilities: (1) the F2a was real, but not of production quality and Gigabyte opted to play safe (and even more safe after F7), or (2) the F2a was a concept design only and the hardware choices of the actual board revision prevent its implementation. Naturally we do hope that the truth is closer to the first possibility and that Gigabyte manages to make a BIOS with more features accessible.

Btw, I'm strongly opposed to marketing RAID1 as "Smart Backup". RAID is not a "backup". If you delete a file accidentally, it is gone for sure as RAID1 obediently wipes out both mirrored copies of it.

Asus markets the RAID0 mode of 5723 as "Super Speed" and that is much closer to truth; any disk of RAID0 set dies and all the files stored over all the disks are immediately lost. Hard to get faster than that.

Re: Ep45-ds5 & dq6

Hi, Following on from above and for interest I thought I would post a scan of my DS5 manual (1001) which has bios F2j mentioned as the demo bios.

As previously mentioned lot more options and Gigabyte Smart Backup tool sounds like it may have the options needed.

Gigabyte may take this onboard and maybe produce a bios that gives the options for smart backup to be configured in a "simple" mode as they have it in F10a, or in an advanced mode giving the options shown earlier.

Thought this may help people understanding the difference that the bios has taken. You can compare this to current manual on Gigabyte website version 1004.

regards,

Harry

Look at TEST0 - HOW MANY Maximum HardDisk Supported???

**mv2devnull** · 08-21-2008, 05:27 AM

Re: Ep45-ds5 & dq6

JMB363 "Supports Port Multiplier with Command-based Switching" on each SATA2 port. Thus, you could connect two Port Multipliers to the SATA2 ports of the JMB363. And IIRC one Port Multiplier can connect up to 15 SATA devices. Most (by google) external port multiplier based disk enclosures seem to take five hard drives. So theoretically you could have 30 SATA disks behind the JMB363 (that is on PCIe x1). You would prefer frame-based switching (FIS), but JMB363 supports the command-based.

SiI5723 is a Port Multiplier. The SteelVine Manager (which is probably what the GA-EP45-DQ6 rev 1001 manual writer had in mind when talking about GIGABYTE Smart Backup tool) manual does implies that the 5723 is usually in external enclosure, with "box temperature" and all. SiI5723 is a Port Multiplier in order to allow the JBOD, SAFE33, and SAFE50 modes. SAFE, SPAN, and FAST all present only one logical drive, and thus would not require the port multiplier bit nor support for PM in the host controller.

The SteelVine Manager manual does explain the cascade of SiI controllers. Yes, eSATA brackets and external SiI enclosures would allow that. IF. If there would be chance to manage the root of the cascade, ie the SiI5723 chip that is on the Gigabyte motherboard.

But having several disks behind PCIe x1 bandwidth is not so nice.

Re: Ep45-ds5 & dq6

I must have read this thread 10 times over and don't yet understand what all those chips are for ?

3 chip that are less useful than one, I now hate this board so much,

It's not any better than EP45-UD3R for total Sata (8)

Can I just do ONE , RAID 1 ?

Steelvine see nothing (w7x64), bios has 2 option and there's no GUI or key to press at boot.

So how ?

Wish to thank you for this in-dept research, and a big F-U to gigabyte for such poor documentation.
