Can I daisy-chain a G-RAID Pro 2TB with a bunch of other G-RAID's?

Hey there,
I'm wondering if there would be any issues adding a G-RAID Pro into my current daisy-chained G-RAID configuration.
- I've got seven 500GB G-RAID's all daisy-chained together and running into my G5.
- Two of my 500GB G-RAID's are RAIDed together so the first one is connected to the onboard Firewire 800 port of my G5 and the other to my additional Firewire PCI card.
- The remaining 5 drives are daisy-chained into the drive that is connected to the onboard FW 800.
This hasn't posed a problem thus far, but I'm wondering if adding a whole new G-RAID Pro is possible with this configuration, or if there's anything I should know before I decide. I left a message for the tech department at G-Tech but they're so busy over there I figured I check in here.
I'm thinking about getting the G-RAID Pro 2 TB because I have 2 projects coming up for which I'll need a whole lot more space than I currently have. If anybody has any other hard drive suggestions I'd be open to them as well, of course.
Thanks a lot for any thoughts,
Joni

Jerry, did you see my post the other day? I don't know if there is a conflict or not, but I've had some serious firewire problems for the last year and just last weekend I was unable to access any media files that were on a lacie for a specific project. And when I tried to copy the files (after closing fcp and running diskwarrior on the drive), I kept getting error messages. When I came in the next day and started the system with the graids disconnected, the lacie performed perfectly. Seems like there might be some sort of conflict. Or just a weird one time occurence. But since I've been having all sorts of weird inconsistent problems with firewire drives and I did have a mixture of lacie and gtech drives my instinct says it might be the source of the problem. I just installed a burly 5 bay sata enclosure, so my need for firewire drives, except for sneakernet, is over.
I post this kind of stuff with the hope that if someone is experiencing weird firewire behavior, they can try to eliminate at least this possible cause.

I have a Mac Pro tower with two internal Hard Discs, each one 2TB. I purchased a 3TB Time Capsule. But it does not allow me to back up because it says there is not enough back up space available. Between the two HDs there are 3.3TBs. Can I daisy chain TC?

I have a Mac Pro tower (OSX version 10.6.3) with two internal Hard Drives, each one 2TB.
I purchased a 3TB Time Capsule. But cannot back up because it tells me there is not enough space.
I have more than 3Tbs to store to the new TC.
Can I daisy chain two TCs to store the 4TBs?
How can I back up only the internal HD that is already full, without backing up the other one?
How can I do back up using Time Machine to back up the 3.5Tbs?
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?

Can I daisy chain two TCs to store the 4TBs?
No, you cannot link to produce a single large partition.
But you can have two separate backup jobs.. and use each partition. That is hard on TM but you can easily get a different backup software for it.
How can I back up only the internal HD that is already full, without backing up the other one?
In TM you do a different setup and exclude the other drive.
But it is better to use an alternative software IMHO.
How can I do back up using Time Machine to back up the 3.5Tbs?
You would need to use a network drive of more than 4TB .. it would also take forever. This is just wrong way to do it. Although you can buy a NAS that will work with Time Machine and load it with disks 16TB is possible.. if you can get a second mortgage.. the fragile nature of TM on 3rd party devices.. would leave me in cold sweat if anything went wrong.
TM is excellent at keeping incremental backups of files that keep changing.. as such you should use TM to backup your OS disk and main user directory.. exclude all files and directories that never change. Back them up separately.
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?
Yes, that is a much better idea. You want to store photos safely and you want to store them in multiple places. If you have multiple TB of photos, dedicate a couple of disks to the backup. ie have at least two copies.. not in backup format.. in straight copy format if possible.. so you can keep one of the disks offsite.
I would be using your MacPro internal disk access, to place the disk onto sata bus and do the copy disk to disk direct. Or even buy esata card.. or sata to esata converter cable so you can use esata box. That will beat any other transfer speed except thunderbolt for which you would need third mortgage. (The MORT in mortgage is significant).
The great jurist Sir Edward Coke, who lived from 1552 to 1634, has explained why the term mortgage comes from the Old French words mort, "dead," and gage, "pledge." It seemed to him that it had to do with the doubtfulness of whether or not the mortgagor will pay the debt.

One more question: Stayed throughput speeds more or less the same as original Firewire (since all my movies are on external disks) or has it become significantly slower?
I haven't done a careful side by side quantitative comparison of what I had on the older Macbook Pro (which had three Firewire800 disks chained together via FW800) versus the new Macbook Pro (which has thunderbolt into which I have connected three FW800 drives daisy chained via the adaptor), mainly because my employer supplied me with these computers and required I turn in the old one when they replenished it with the new one. However, I can say this -- one of the FW800 externals is used for Time Machine, another for making entire disk clones, and the third is for misc storage. I have seen Time Machine start up during a disk clone (with SuperDuper) and there seems to be no impact. The disk cloning is generally pretty intensive on disk and cpu resources, but thunderbolt seems to have a much bigger capacity for throughput than firewire and hence can apparently accommodate multiple streams of FW800 data going back and forth with no apparent impact on each other. The main limit seems to be the FW800 speed itself, not thunderbolt. I see ~ 60 MB/s or more which is as much as I have ever seen on FW800. Ultimately, the ideal setup will be thunderbolt drives daisy chained together, I would expect hundreds of MB/s, but I don't see many of these thunderbolt drives on the market yet. Even better would be solid state drives ...

How many firewire g-drives can I daisy chain on my mac mini
From personal experience, if they are bus powered portable drives,
the answer is none. For what ever reason, they are draw a lot of
power and are probably near the edge of the bus powering specs.
Then again, these were the fastest of all the portable FW drives that
I have (Iomega and Seagate being the others), which may have
something to do with it.
I had also noticed an issue with them even with USB. Plugging one
into the Mini or even a powered USB hub would be fine, but 2 would cause
both to be inaccessible, unless I used a couple of USB "Y" cables
that would distribute the power across other ports.
If they are externally powered, you could string a bunch.

Can i daisy chain external drives

I have 3 drives but only 2 800 wire ports. Can I daisy chain, or use a 400 wire?

daisy chaining should work fine. I used to have about 11 drives chained (which was pushing the envelope - but it worked with dv material). If at all possible, avoid firewire 400 as it will reduce your thruput.

Can't daisy-chain Firewire drives reliably from 1-port Powerbook. Hub??

I have found that I cannot get a daisy-chained Firewire drive to mount more than 50% of the time. This problem doesn't happen with Tiger with the same drives. I have tried 4 different brands of late-model Firewire drives (Iomega, Smartdisk, Maxtor, and Seagate) with different cables and what happens is that a drive that is directly attached to the 12" Powerbook will mount, but the second chained drive fails to mount a majority of the time. Since I only have one Firewire port, this is preventing me from using more than one drive at a time, and I lost two Firewire drives to corruption today. Three out of four partitions lost contained bootable backups of Leopard and Tiger. Ouch!
This issue could prevent from using Leopard with my Powerbook, which is supposed to be Leopard-compatible. I can't remake the clones too easily with only being able to attach one drive at a time. I am thinking I will order a Firewire hub and try that, but I am not sure if that would be a solution, and I am wondering why I can always daisy-chain under Tiger, and not under Leopard. Does anyone have experience with Firewire hubs and Firewire operation details? Will I be able to get reliable Firewire with a hub?

I have exactly the same problem !
I have found this :
Using Multiple FireWire Devices at the Same Time
Power Macintosh computers can transfer perfect digital video (DV) on FireWire when no other devices are using the FireWire bus. If you have problems transferring digital video, make certain that no other FireWire devices are being used at the same time. Turning on a DV camera that is already connected may cause a FireWire hard disk to stop working. If this happens, turn off the camera and verify that the hard disk has recovered. Then unplug the FireWire cable from the camera, turn the camera on, and reconnect the FireWire cable to the camera. Check with the hard disk vendor for a possible firmware update to prevent this problem.

At the moment I can't upset what I'm doing to test it but I intend to do that as soon as I finish copying transferring...

Can You Daisy Chain Firewire 400 and 800 Mixed?

I would like to purchase an External Drive. I'm looking at a FW800. What I'm wondering is, Can I daisy chain devices mixed in.
I Want to run a FW800 Bilingual cable from my Powerbook to the External Enclosure. From the Ext. Enclosure, I'd like to have take my second FW800 port and take a cable that converts Firewire 800 to Firewire 400 and plug in another item. Is this possible?
Can I mix and match FW devices using separate protocol in a daisy chain configuration?

Russ,
Yes, it is possible. I have a drive that works on FW800, FW400, or USB2. Connected to the second FW800 port on that, I have an adaptor cable, a FW400 cable to a FW400 drive, and another FW400 drive connected to that . All 3 drives are on the desktop of my PowerBook. When I read your post, I had the only first drive connected to the iBook with USB2.
The only problem I've run into was trying to copy a 200G drive on FW800 to a 250G drive on the FW400 port on the PowerBook. Working overnight, it managed to copy ONE Gigabyte! I hooked them up as they are now, and copied the whole shebang in about 45 minutes
I picked up an empty drive case, 800/400/USB2 combo from OWC and a 250G Maxtor drive at CompUSA for about $100 less than I could get a 250 FW800 drive anyplace. http://www.macsales.com

Can I daisy chain IDE and SATA drives w/ FW400?

I have an 250GB IDE drive in ann ext enclosure with two Firewire 400 ports. Can I daisy chain a SATA drive to this or does it have to be another IDE drive?

If both are in their own Firewire case then yes. The FW interface converts whatever internal interface it is so the computer only sees it as a FW device.

Can you Daisy Chain the WRT54GS?

Hello,
I've recently purchased three LInksys WRT54GS. I've read the FAQ but not seen my exact problem listed.
Can the WRT54GS (the super G version) be Daisy Chained (1 router, 2 as APs with dhcp disabled) and if so which port should link to from router #1, port1 or the "internet" port.
If I use the port marked "internet" than I get great signal strength but a lot of drops. However if I use port1 on each of the routers I'm using as AP's then I get low signal strength but less drops.
Configuration so far:
router-1 (dhcp enabled)
ssid - router1
channel 1
192.168.1.1 /255.255.255.0
router - 2 (dhcp disabled)
ssid - router2
channel 6
192.168.1.2 /255.255.255.0
router -3 (dhcp disabled)
ssid - router3
channel 11
192.168.1.3 /255.255.255.0
thank you for the help!

These answers are incomplete oin their face:
You described the config as:
router -3 (dhcp disabled)
ssid - router3
channel 11
192.168.1.3 /255.255.255.0
which tells nothing about the "WAN and LAN addresses cannot be the same"
The "Local IP" address cannot be the same as the Internet (WAN) address
"Internet Setup" or "Netword Setup"?
It is as if you have never looked at the config screens in this router.
How is your local PC connected to the second router supposed to get the DHCP address when there is no route to the first router? Then, how can you connect to the second router to configure the route? I set a static IP for my PC and I can connect to the second router, but even after setting a route, which cannot have a 0.0.0.0 gateway, cannot ping the first router.
Let's tell the whole story here, the complete configuration. It's a simple expectation to have a second router hard-wired to the first router, and the secod router providing "distant" wireless access to the network.
The whole story folks?

You use Restore to get the latest firmware build, not the Update button. You can only use the Update button, if there is an iOS update, say iOS 5.1.

Can I daisy chain 30" apple monitor to thunderbolt HD on macbook pro?

I have a 30" apple monitor plugged into this adapter: http://foliovision.com/2009/12/apple-dual-dvi-mini-displayport-adapter-mb571z that in turn is plugged into the thunderbolt port as well as one USB port on my 2011 macbook pro i7.
I want to buy a Lacie Big5 thunderbolt RAID system, but I only have one thunderbolt port. will i be able to daisy chain the monitor to the thunderbolt RAID?

I don't want to assume that it will work because it a little bit different on the Retina. All of the 2012 line of MacBook’s utilize the same thunderbolt controller which does support 2 displays and 4 10Gbit/s data (even the MacBook air 11" can support 2 external monitors and it's own display). But i think that the controller is hardwired for each port meaning each port only has 2 10Gbit/s data and 1 display. I haven't been able to confirm this because I don't have 2 thunderbolt displays and i was wondering if anyone has tried this. The reason why I ask is because I'm doing research on all of the new MacBook’s and their Thunderbolt controller.

Can I daisy chain two mac pros so that I'm using one monitor and keyboard

Can I use two mac pro's with one monitor, keyboard & mouse? The two different machines have two different operating systems (Snow Leopard / Lion). One machine is brand new and the other is 5 or 6 years old.
I want to use both machines in tandem so that I can leave something to render while I work on something else.

KVM is an answer -- maybe. I use one for two machines to share one of my monitors (a VGA) and my keyboard (the second older machine seems to have sleep problems if I share a usb mouse on the kvm however).
The trickiest part of choosing a kvm is trying to find one that can handle the video; one that can handle the required bandwidth, and the connections. If one computer uses, say DVI, and the other mini-displayport, then you need to figure out which kvm can handle that with one (or both) of the machines using adapter(s).
You said one of the machines is brand new. Then it probably has thunderbolt. So you would need a mini-displayport, dvi, or vga adapter depending on the monitor. That means the older machine will need a similar connection since whatever kvm you get will have the same kind of ports for both inputs and its output.
A wild card here (at least in my mind) is if the newer machine has thunderbolt. While a mini-displayport display can be plugged into a TB connection, it is not clear that such a thing will work through a kvm. That is unknown territory I think at this point.

Can I daisy chain two Thunderbolt displays to the new MacBook Airs (July 2011)?

I have last year's MacBook Air -- probably the best Mac I've ever had and I've had a few. I looked at using multiple displays last year, but the reviews for the major 3rd-party solutions really demonstrate how little is possible.
I see Apple says you can double up on displays for the MacBook Pro (I have a pre-Thunderbolt one unfortunately), what about the new (July 2011) MacBook Airs?
Anyone tried? Anyone know?
(I have a 30" Dell display, but it is, and always has been, very flakey when it comes to connecting to a Mac laptop).

You can thank Intel for that.
The sandy bridge chips all have integrated graphics, and before they were released -- they took nvidia to court claiming they didn't have a "license" to make GPU chipsets for the sandy bridge line. Intel won, and consumers lost.
The solution most manufacturers are using for notebooks is graphics switching (nvidia optimus like technology) -- which basically uses a discreet GPU along side the intel integrated GPU, and switches between the two instantaenously based on the workload and \ or battery life -- this is how the macbook pro's with the ATI gpus work.
Since there isn't enough space physically inside a macbook air for a discreet GPU, and since no company in the world is allowed to make a shared GPU for intel's sandy bridge chipsets -- the only solution is to use the integrated graphics that is in the processors -- Intel HD 3000. Intel basically has the monopoly here...there is no legal solution in the world another company can provide thanks to our wonderful court system
Wanna know the really sad part about the Intel HD 3000 GPU? The Nvidia 320M (the GPU used in the previous model 2010 macbook air -- chip was released to the market in April of last year) actually out performs it in some benchmarks -- that's right, a 1+ year old shared gpu from nvidia outperforms Intel's 2011 integrated graphics.
Intel ***** at graphics, period.
The only other solution I can think of is for you to get the "Echo Express" product from Sonnet:
http://www.sonnettech.com/product/thunderbolt/index.html
It's basically an external bay that will allow you to put a PCIe GPU inside it, and it would then connect via thunderbolt to the macbook air.
You would then use the minidisplayport connectors on the PCIe GPU to connect to the apple displays -- I believe any modern ATI or Nvidia GPU can support up to 3 or 4 external displays.
Unfortunately, sonnet's bay is not released yet, and you'd also have to make sure the PCIe GPU you get supports both thunderbolt AND os x....so yeah, kind of slim pickens right now
EDIT:
So apparently the macbook pros can daisy chain two thunderbolt displays -- Apple has a picture of it on their site:
http://storeimages.apple.com/1867/as-images.apple.com/is/image/AppleInc/MC914_AV 7?wid=1200&hei=1200&fmt=jpeg&qlt=95&op_sharpen=0&resMode=bicub&op_usm=0.5,0.5,0, 0&iccEmbed=0&layer=comp
I just bought a new mac air too...I was gonna get a mbpro but they are just too expensive -- the one I configured was at around 3000$
Wanna know what's lame about using the thunderbolt display with the mac air? So the new mac air has the magsafe connector on one side and the thunderbolt connector on the other -- they're not on the same side like the macbook pro is (see picture) -- so basically the cable is going to have to slack around the back of the macbook air -- who designed that? Must have been smoking some good meth ;p
