  1. I'm running the EVGA 680i A1 with an Areca 1210 in the x8 slot with no troubles. Completely painless. (And for completeness sake, I've got two 7K1000's in RAID 1)

    Partitioning based on number of spindles

    You're using the term spindle, but you are referring to platters. When partitions are created, the partitioned space is created from the outermost edge of all sides of all platters equally.

    Hitachi 7K200 or WesternDigital Scorpio?

    I rebuilt my Toshiba M5 with the 7K200 (was 80GB 5400rpm generic toshiba drive) and the difference was night and day. But I don't think it's all about the rotation speed. It's certainly a factor, but right now it looks like Hitachi has the edge in the firmware department since they're leading both with the 7K200 and the 7K1000 in the desktop space. I don't notice the drive either from a noise or heat perspective. I bought the drive to help bridge the gap between laptop and desktop performance since my employer basically gave me a choice between a desktop and a laptop. Other people complain about the performance of their laptops a lot, so I think I made the right choice with the 7K200. YMMV

    Hitachi 7K1000 Question

    I have wondered this, myself. I don't know for sure, but I found this doc at their website: http://www.hitachigst.com/tech/techlib.nsf..._7_Western2.pdf It lists all the part numbers you have listed under the category: 'Part number/Alternate part numbers'. My guess is this is either batch or assembly line ID's.
  5. Not that I can see. Your spare drive is essentially useless with RAID 0 - it's nice that you have a drive to rebuild with, but that's only good if you are building from scratch. Probably would be best to build with RAID 5 next time. Less disk space, but you do get some fault tolerance. You did do the right thing by getting your important data off.
  6. IOps, IOPS, IOPs, etc. stands for IO's Per Second. An IO is a read or write operation. The general statement that IOPS are important in a server environment is generally, true. Transfer rates are normally only important when you are performing sequential reads of contiguous data. Like the other person mentioned, since you're listing RAID 0 and also a single-drive configuration, it looks like your data isn't important or can be easily recovered.
  7. I'm with the previous posters. I do infrastructure for an application with 8 EMC Clariion class SANs (>2000 spindles). We choose SANs for availability/reliability and because we can scale a huge number of disks for performance. Disk for disk, you won't see an advantage over DAS. But DAS cannot scale the way a SAN is able to. For example, I have a 20TB file server (DFS) cluster with a dedicated SAN. The 20TB is broken into 2TB LUNs (RAID 5 in this case) and exposed to an 8 node MSCS DFS cluster. We have the cluster groups/resources/LUNs divided up so that 2qty 2TB LUNs exist in a single cluster group. There are 5 of these cluster groups, and we normally keep them spread out over 5 of the 8 nodes. The load, on an average day, is sometimes so high that collapsing 2 of these cluster groups onto one node takes the 1GigE NIC usage to 60% or higher. There's no way a single server can handle this workload. DAS would just be a non starter. From what I've seen, the 800lb Gorilla in the room when you're talking about a SAN is poor design. Know your workload, know the capabilities of the FC infrastructure (HBA's, multipathing software, Switches, SAN Controllers, etc). Know your SAN engineer, buy them a drink and have them walk you through the design. When I am going to spend >$100K on a piece of hardware, I get pretty anal. I don't ask my management to approve an order for a SAN design I haven't gone over myself.

    Hitachi Travelstar 7K200

    Eugene, are there plans to add the 7K200 to the performance database?

    Real gigabit speeds

    Sounds like you removed the network bottleneck to reveal the next one, which is likely hard drives. From the setup you list, it looks like you're moving files between individual hard drives. Maxing out a GigE nic for file transfers usually requires a RAID array with a lot of disk and/or multiple file copy sessions simultaneously.
  10. FYI, if you join EVGA's forums and log in you can search and find info on this topic. I was looking for the same info, and it does look like there are a number of people using the x8 slot for RAID controllers successfully. I don't know about 3ware, didn't seem like anyone on the forums had tried it that I could see.
  11. Yep. Your line would then read multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /noexecute=optin /fastdetect /PAE Note that you do NOT need to add /PAE when you have the /noexecute=optin setting configured. PAE is required for noexecute and is turned on automatically. See here. To use these processor features, the processor must be running in Physical Address Extension (PAE) mode. However, Windows will automatically enable PAE mode to support DEP. Users do not have to separately enable PAE by using the /PAE boot switch. The RAM is probably not showing because of PCI devices grabbing it like others have suggested.

    RAID 1? 2? 3?

    I just happen to have a couple DL380 G3 servers with 5i Smart Array controllers sitting next to me. I don't see an option in the Array Config Utility to change the current RAID 1+0 array into 0+1. I can perform a migration to 0 or 5 or change the stripe size. That's all it offers. What steps are you taking to do this? Note: RAID level migration is not the same as splitting 1+0 into two RAID 0 arrays. So, on the 5i, it seems that 1+0 is not the same as 0+1. I don't have a 5300 or 6400 series controller to try that with, but I can take a look when I'm at work. What controllers have you done this with? Checked a 6400 series and a P800 Smart Array controller, and neither will split 1+0 into two stripes. I'm done with this unless someone can be more specific about it.

    Why not RAID 1 with an SSD and a Raptor?

    Generally with any RAID level that involves parity if one drive is slower than the other, you're limited by the slowest drive, so that combo probably wouldn't work as you expect. The Raptor would be slow to seek/access the data, but the SSD wouldn't. The SSD will be way faster accessing/seeking, but slow to write (typically, though they're getting better). I agree with Trinary that SSD's aren't fully matured yet. I'm intrigued by what they offer, but they're not totally prime time ready at the moment.

    Hitachi Travelstar 7K200

    I picked one of these up and rebuilt my Vista Ultimate laptop (Toshiba M5) on it. The old drive was an 80GB 5400RPM SATA 1.5 and it was a dog. The 7K200 has pretty much transformed my machine. I keep waiting for it to get slow like it was with the old drive, but it hasn't happened yet. My Vista 'Experience Index' rating on the old drive was 4.1. The 7K200 is rated by Vista as 5.4.
