How many SATA-harddisks?

Hello,
how many harddisks does the xserve "support"...
a) without raid-card
b) with the raid-card
I know, the xserve has "only" three modules but i need 4-6TB storage and i don't have the money for promise-solutions... [if possible: 6x1TB with Raid 5, i know, then I need the raidcard]
In the Mac Pro you can put 6 harddisks, is this posible for XSERVE too (e.g. the other 3 harddisks outside the xserve)? Do I need adapters or special cables?
Who can help?
Thanx
osxfan

Definitely you will need the RAID card, but I'm not really sure the RAID card that's part of Apple's price list has an external interfaces. You might be able to 'string' an external SATA connector to one of the PCI slots and have it all tie into the same RAID card.
I don't have any experience with the Apple RAID card since its announcement. I can't speak to what interfaces it has available beyond the 3 connectors it would need just to hook up to the internal Bays of the Xserve. If there are any spare connectors, you could probably rig up something to get an external SATA connector available to connect eSATA drives up.

M93p tower: how many SATA power connectors?

I'm planning on buying an M93p tower for the first time (I already have an SFF machine), and want to use four SATA devices in it (two internal SSDs, a DVD drive, and a front-panel-accessible backup drive).
Will the power supply come with four SATA connectors, or will I need to buy one or more SATA power splitters?
Many thanks for any help with this question.
Solved!
Go to Solution.

There's one spare SATA-3 data connector on the motherboard (you'll need to buy a SATA-3 data cable) and a spare SATA power connector off of the PSU. So for sure you can use that spare power connector to install a second internal hard drive without needing a power splitter of your own. I installed a 256GB SSD in the spare internal drive cage, leaving the Lenovo-provided 1TB SATA spinner just where it was. I then copied the OS system contents over from spinner to SSD, changed the boot sequence in the BIOS to point to the SSD as the first drive, cleared the spinner, and that gave me the original spinner as a fully available 1TB data drive. I actually created several partitions on both SSD and spinner for some flexibility.
The CD/DVD drive is already connected for data and power, so you don't have to worry about it. So the one spare power cable connector and your own data cable set is all that's necessary to install a second internal SSD drive. Remember, there is only a 280W PSU in this machine so you can't really put too much in it.
I use an external USB 3.0 drive for backup. It's actually a SATA drive inside the enclosure, and USB 3.0 performance is around 1Gb/sec which is perfectly acceptable. No need to worry about another SATA drive with power/data requirements.
You're going to probably want to install an upgraded low-power medium performing graphics card, rather than buying the Lenovo-offered HD8570 for $130. It's not worth the price for the performance it provides (about 25Gb/s bandwidth). Your best bet is to install an R7 250 (1GB DDR5 memory, with three digital connectors), either a full-size version or low-profile version with full-size bracket. This low-power card provides about 73Gb/s bandwidth and does not require additional PCIe power connection (which there is none of off of the 280W PSU). Works perfectly in this machine.

H520 how many SATA ports

I am trying to install two additional SATA HDD in my H520 along with the Included HDD and DVD Drive.
No matter how I connect the devices, when I check in the BIOS the device connected to SATA 3 is never detected.
Are all 4 SATA ports usable in the H520?

How many SATA drives?

I have 2 SATA drives on Intel ICH5R as RAID0. When I try to connect a third SATA drive to the Promise controller it is not recognized. Can I have drives connected to both controllers?

You need to go into the bios and enable the Promise controller for either SATA or RAID, depending on what you want, and then install the appropriate driver. You can have a total of 4 SATA drives and 6 PATA drives on the onboard controllers, providing you are using W2K or XP.

Sata how many

ok this question may seam really dense(eg stupid), but how many sata drives can you put through one sata connection on your mother board. Ide I know take two. But as far as I can see sata only takes 1. well I have only seen cables for one. So I was just wondering with the suspicion that this question bight be stupid. (but ive had a few drinks and don’t mind looking like a fool.)
so how many ,

How many IDE drives & CDrom can be installed with SATA drives??

How many IDE drives & CDrom can be installed with SATA drives??
i have 2 IDE hard disks & 2 CDROM drives: can install SATA hard disk added to these drives or do i have to remove some???
& if it can be added, can i install 2 SATA drives???
THX in advance

The 3 versions of this board that are available are:
875P Neo-FISR (PCB 2.0)
875P Neo-LSR (PCB 1.0)
875P Neo-FIS2R (PCB 1.0)
All of these boards will have the following ports provider by the chipsets ICH5R south bridge.
2 x SATA (Supporting 2 SATA HDD drives)
2 x PATA (Supporting 4 IDE devices)
All 6 of these can be used at the same time (provided you are using win XP or 2K) you just need to make sure yor BIOS is set right.
->INTEGRATED PERIPHERALS
->ON-CHIP IDE CONFIG
ATA CONFIG: S-ATA ONLY or P-ATA ONLY
S-ATA/P-ATA KEEP ENABLED: YES
OPERATE MODE:
If you set to "legacy mode" S-ATA are set to channel 1 and 2 and P-ATA to channel 3 and 4. If you set to "native mode" P-ATA are channel 1 and 2 and S-ATA 3 and 4. You can only use the raid functionfon SATA in native mode.
If you have the 875P Neo-FIS2R (PCB 1.0) you will also have the following ports provided by the Promise PDC20378 PCI controller:
2 x SATA (Supporting 2 SATA HDD drives)
1 x PATA (Supporting 1 Master IDE HDD drive)
The PATA port is limited to 1 Master HDD by the lite BIOS. This can in theory be upgraded to the full BIOS supporting a master and a slave, but this may obviously void your warranty.
So the answer to your origional question is:
2 x SATA HDDs and 4 x IDE HDD/CDROM if you have 875P Neo-FISR (PCB 2.0) or 875P Neo-LSR (PCB 1.0)
or
4 x SATA HDDs, 1 x IDE HDD (2 if you modify the BIOS) and 4 x IDE HDD/CDROM if you have 875P Neo-FIS2R (PCB 1.0)

Incompatible SATA harddisk with PowerMacG5

Hi..
I bought a new Power Mac G5(Dual Core 2.5 GHz) with 250GB Serial ATA hard disk(pre-installed).
But the system is not at all stable and showing problems from the beginning itself. Its frequently hangs when boot up,when contacted the supplier,they replaced the system,but the problem remains.
I tried many things like migrated to Adobe CS2,used less fonts.
The latest problem is that it fails to mount the harddisk.When I opened the case,it was a Western Digital SATA harddisk with 250GB capacity, when I visited the Western Digital's Website,
its clearly mentioned that that type of hard disk is not compatible with the OS X or OS 9. Then how comes I get the System like this with incompatable hard disk preinstalled..?
Please visit western Digital's website for the more informations
http://www.wdc.com/en/products/resources/DriveCompatibilityguide.asp
Thanks & Regards
Prabith

Dear Sir,
Thanks for the reply.
I dont feel its a refurbished machine..Its taken from an apple reseller only..I formatted the harddisk twice or thrice to reinstall the OS.But it will work for one day,and it will show the problem again.
about Western Digital HDD..Their site tells the incompatability..
Let me quote from the site
Which internal drive is compatible with my operating system: SATA or EIDE?
Your operating system, as well as your hardware, must support the hard drive you choose:
Operating System WD SATA Hard Drive Compatibility WD EIDE Hard Drive Compatibility
Windows® 2000 or XP Yes Yes
Windows 98SE No Yes
Windows 98 No Yes
Mac® OS X No Yes
Mac OS 9.x No Yes
Note: Compatibility may vary depending on user's hardware configuration and operating system.
Its clearly mentioned that OSX will support IDE hardisk but not SATA

How many hdd's can I install in Quicksilver

Have the SIIG Serial ATA 4 Channel PCI-M card running one 250GB HDD at the present with 1 running off the original system bus. How many can I add total to this system? Owners manual states I can run only 2 total in this machine. Is it true that now I can add a large HDD to the original bay without using the SIIG card and whole capacity will be recognized?
G4 Quicksilver 733 896mb ram Mac OS X (10.4.8)

Hi
You should be able to install four hard drives fairly easily.
You can physically fit four into the case, one in the front bay, one in the middle bay and two in the rear bay (one on top of the other in the U shaped bracket).
Assuming you don't have a Zip drive installed, you have the Molex power connectors for four drives, although you may need an extension cable so the power connector that's intended for the Zip drive will reach one of the hard drives. If you do have a Zip drive installed, you'd need a splitter cable to power two drives off one cable.
You have the data connectors for at least four drives. Two ATA drives can be connected to the onboard ATA controller and four SATA drives can be connected to the SATA PCI card (assuming it's a four port version).
The capacity limitation still applies to drives connected to the onboard ATA controller via the ribbon cable. Large drives can be added to any bays, but they must be connected to the PCI card for the full capacity to be recognised.
The manual probably says two ATA drives can be installed (using the onboard ATA controller) or three SCSI drives can be installed (using the supplied SCSI PCI card if relevant). There's no reason why you can't add additional drives using a SATA PCI card.

Is there any limit on how many records a cursor can hold?

Hi Everyone,
This is Amit here. I want to know whether there is any limit on how many records a cursor can hold.
I have a program in which i am creating a cursor and passing it to another procedure as an input parameter. But the count of cursor query is more than 15 Lakhs. The program is running forever.
Just wanted to know whether the huge data is the problem.
Thanks ....

Now multiply that waiting for I/O time with a million - for a million rows. Or by a billion, for a billion rows.
Is "+huge data+" a problem? Not really - it simple needs more work to get that amount of data from disk. More work means slower performance. It is that simple.
Which is why the row-by-row approach used by many developers is wrong. You do not pull a million rows from disk and process it in PL/SQL or Java or .Net. Heck, you do not even pull 10,000 rows like that.
The correct approach is to think data sets and use SQL to process that for you - and only return the bare minimum of data to the application layer. Maximize SQL. Minimize PL/SQL and Java and .Net.

ISCSI MPIO, how many path do I need to create

Hi,
I've a server with 4 NIC connection to a DELL MD32xx which have 8 NIC.
My question is how many path do I need to create under iSCSI connection.
Do I need to create a path from each Server NIC to each MD32xx NIC, which will make 32 connection (and doesn't make sense).
If not, how should I proceed, I've looked at many example and none seem to cover that kind of situation, they just directly connect the server NIC to the MD32xx NIC instead of going through switch for redundancy.
Thank

web dude

Hi, Web dude -
What do you mean by this? They have power packs plugged to them and they're plugged in a strip?
Yes.
The firewire bus is designed to be able to provide power for use by an attached device, in addition to providing a data pathway. There is a limit as to how much power can be provided by that bus. Such power is used by the device to operate its mechanics - in the case of a firewire hard drive, to run the motor that spins the platter(s) in the drive.
Many, if not most, firewire devices can also be powered by using a separate power supply, often an external transformer although some may have that transformer built in. This necessitates a separate connection to line power, typically to an outlet on a power strip or surge suppressor strip.
When I ordered each of my firewire drives, I also ordered the optional power supply for it. This makes each drive non-dependent on the Mac for operating power.
How should I prevent over heating my G4?
As far as keeping a Mac from overheating, the primary defense is to keep it clean inside. Dust is both an insulator and a restrictor of airflow. Using canned air regularly to blow dust out of the inside of the Mac, and to clean its fans, goes a long way to keeping it from overheating. Using a vacuum cleaner is not recommended - it's too easy for the nozzle to bang into something, and the airflow going into a plastic nozzle can create static electricity, which you do not want around any printed circuit board.
Keep the machine itself adequately ventilated - it needs a reasonably unrestricted supply of fresh air. If you place the tower on the floor or under a desk, make sure there are several inches of free space between the case and any obstructions. Usually, keeping it on a desktop reduces the amout of dust it will ingest.
In addition, whenever possible use external power for a device - this applies to firewire and USB devices.
Hard drives generate a fair amount of heat. G4 desktop models are designed to accommodate up to four internal hard drives, though it is possible to install more than that. If you go beyond four internal drives in a G4, consider replacing the fans with ones with a larger capacity to handle the increased heat load.
If you replace the CPU, be sure you follow the instructions with the new one re making sure the heat sink on the new processor is installed correctly.

How many amperes can be powered by the USB Port

I'm looking for a new USB Powered HD (in the 160-250 GB range) that my AirPort Extreme's USB port can power.

How many amperes does the AirPort USB port "support"?
Do you have a USB powered HD that works fine with the APEBS (2.5" in the 160-250 GB Range)? - Make and model please?
Thanks in advance.

Hi Allan,
You mention you wish to use the older SKU p/n SRW224G4P, which has been refreshed and replaced by SRW224G4P-K9-NA
.Here is the EOL notice fior the SKU you detailed;
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps9967/end_of_life_notice_c51-626527.html
Why not avail yourself of the newer 300 series switch such as SRW224G4P-K9-NA .
I am using beta code version 1.1 code on my unit.
Version 1.1 will be Generally Available at the end of this month ( fingers crossed), and Version 1.1 firmware supports CDP.
See datasheet for the new product, generations ahead of the old p/n that you mentioned.;
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps10898/data_sheet_c78-610061.html
Anyway the AP1240AG isn't a pre-standard device but supports standards based 802.3af, hence i really see no benefit in using the older product..
Datasheet on the AP1240AG correlates with your data, maximum power drawn is 12.4watts.
Allan, your calulations seem spot on.
SRW224G4P-K9-NA as well as the older switch you mention both support aPOE power budget of 180W.
I personally like to be slightly conservative in terms of loading the switch up.. I prefer to spread the load between switches if i can.
But the GUI of the 300 series switch will show the power drawn by the devices.
The device circled below is a AP1142 with wireless-a turned off.
Have fun,
regards Dave

How many Hard Drives ?

I've been fortunate to receive a PowerMac G4 733mhz (Digital Audio) along with a Sony 20" CRT monitor at no cost and I'm looking to get all the performance that I can out of it.
So far I've maxed out the RAM and added an iogear USB 2.0 card along with a SIIG Utra ATA 133/100 Pro controller card. The Radeon 9800 pro video card is a couple weeks away yet.
I now have a 160gb and a 60gb as master/slave on the main board, and another 160gb on the controller card in which I'm adding another 80gb to tonight.
I am wondering how many hard drives I can add before I have to start worrying about the power supply. Keep in mind that I'm going to be adding the video card in the future.
I also see that SIIG card says OSX 10.1 or later, does this mean that I cannot connect a drive that boots into OS 9 to the card? Or a drive that may have Yellow Dog Linux?
Thanks, I'd appreciate any input about this new project of mine.

Hi-
OK, let's talk power.... This is what we have to work with (may be slightly higher depending on PSU model):
DA 338W PSU
+5V=20A
+3.3V=24A
+28V=4.04A
+12V=8A
-12V=0.25A
Total on combined +3.3V and +5V =126W @32A
Of course, there is a big difference between idle and load power consumption, but I will list maximum power consumption values. Various requirements are:
ATA/100 Hard drive- Read/Write, approx. 12.8W [email protected], [email protected]
Optical Drive- Full Speed (42x) read, approx. 5.6W [email protected], 15.7W [email protected]
Memory (per 512mb DIMM) 1-3W combined 3.3V,+5V,[email protected]
PCI and AGP slots combined max +3.3V, +5V=62W, AGP (only) up to 20W
Firewire Bus 15W+25V
USB Bus 5v@500mA per port
733mhz PPC processor 1.6V 15.6W (Idle) 22.0W (load)
Fans (combined) +12V [email protected]
As for the Radeon 9800 Pro, under full load, the power requirements are:
+5V [email protected]
+12V [email protected]
+3.3V(AGP) [email protected]
+5V (AGP) [email protected]
+12V (AGP) [email protected]
Points to consider (no particular order):
-An ATA hard drive at idle, will still pull 7.2W and at Standby, will pull 1.4W.
-Unless you are running 2 RAID sets, you would rarely, if ever, have 4 drives simultaneously in Read/Write.
-One process that will push a system to the max is disc burning. Consider CPU at load, one, possibly two hard drives at Read/Write load, and the Optical drive at load. (For all who care, this is why we don't multi-task during burning). Without multi-tasking, the graphics power draw is minimal.
-Weak point of early ATX PSU revisions was the 12V rail. The G4 PSU also has a weak +12V rail (only 8A).
(Run a dual internal RAID, and try to burn a disc..... well, you better set the machine up as a headless server.....)
-Total combined +3.3V, +5V wattage and ampherage is sufficient for most fully loaded system and bus combinations.
-The power requirements of the 9800 Pro are all within the maximum limits of the various voltage rails of the OEM PSU.
-A 237W PSU equipped Sawtooth will run without problems with two hard drives (one system, one storage), a 2.0ghz 7447 processor, USB 2.0 PCI, Radeon 9800 Pro and AC VGA fan. Additional hard drive (scratch drive), PCI cards, HDD fans and lighting overload the +12v rail for operation at load with disc burning. (we're talking about real life experience here...)
-Hard drives are heat producers, and an external firewire connected housing can allow for better overall system operation by reducing interior clutter and heat production.
-High interior temperatures reduce the ability of the PSU to cool itself, and thereby reduce it's ability to produce reliable power under load, in the heat.
-Old ATA hard drives are power hogs and hot in comparison to current SATA drives. Switching to two larger SATA drives will reduce load requirements by 3-4W per drive, as well as reduce heat production. Required use off a SATA PCI controller card eliminates the capacity restriction of the native ATA controller. Switching to SATA saves space, power, and cooling needs.
-And, final (random) thought to consider, a dual 500mhz Gigabit Ethernet (same PSU as the DA) will run two ATA drives simultaneously, burn a DVD, with a 9800 Pro installed, without any problems whatsoever. The same machine will run 3D graphics intensive games at enjoyable framerates, without problem. Internet video, on line games, etc., are all enjoyable, with reasonable performance for the given CPU speed. All uses of the machine are without problem, with the added graphics benefit provided by the 9800 Pro (Yep, another real life experience).
Now, you decide....
