similar to: program in Wine doesnt see SATA solid state drive

Hi, I''ve ordered a new server with: - 4x600GB Toshiba 10K SAS2 Disks - 2x100GB OCZ DENEVA 2R SYNC eMLC SATA (no expander so I hope no SAS/ SATA problems). Specs: http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-emlc.html I want to use the 2 OCZ SSDs as mirrored intent log devices, but as the intent log needs quite a small amount of the disks (10GB?), I was wondering

I''ve got two recent examples of SSDs. Their pristine state from the manufacturer shows: Device Model: OCZ-VERTEX3 # hexdump -C /dev/sdd 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 1bf2976000 Device Model: OCZ VERTEX PLUS (OCZ VERTEX 2E) # hexdump -C /dev/sdd 00000000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| *

Same as its brothers/sisters, it's optimized for 4 KB blocks. /* * OCZ Vertex 4 SSDs * 4k optimized */ { T_DIRECT, SIP_MEDIA_FIXED, "ATA", "OCZ_VERTEX4*", "*"}, /*quirks/DA_Q_4K Borja.

I know, I probably gave a lot of people heart attacks just from that title. I'm not saying that I would actually try flashing my BIOS with WINE, I was just wondering, purely out of theoretical curiosity, if it's even possible to flash the BIOS by initiating an "exe" BIOS flasher from within WINE. I would suspect not, given that WINE "can't even" run Windows

Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)

Hi folks, an Asterisk (www.asterisk.org) box will be built with the following specs and I wanted to know if CENTOS has a built process/config/parameter/special distro to target the AMD Opteron Dual Core plataform: 2 amd opteron 265 dual core 1.8 Ghz 2mb l2 cache 2x1024 ocz c2-6400 dual channel gold GX XTC 2 Seagate 16mb cache 300 GB barracuda 7200 drives another 2 Seagate 500 GB 16mb cache

I''m running a mirrored pair of 2 TB SATA drives as my data storage drives on my home workstation, a Core i7-based machine with 10 GB of RAM. I recently added a sandforce-based 60 GB SSD (OCZ Vertex 2, NOT the pro version) as an L2ARC to the single mirrored pair. I''m running B134, with ZFS pool version 22, with dedup enabled. If I understand correctly, the dedup table should be in

Hi everyone. Some body knows why my instalation always says Could Not mount root device (0,0), then reboots, i try to compile my own dom0 kernel, but always says the same thing. I''m seeking on create the initrd image, but nothings works. :( The currently hardware profile is this. Intel Server Board SE7230NH1-E (VT Enabled Motherboard) Intel Pentium D 830 CPU (3Ghz x 2 CPU) 2 GB

Hi, I don''t know if it''s already been discussed here, but while thinking about using the OCZ Vertex 2 Pro SSD (which according to spec page has supercaps built in) as a shared slog and L2ARC device it stroke me that this might not be a such a good idea. Because this SSD is MLC based, write cycles are an issue here, though I can''t find any number in their spec. Why do I

I set up a new system that includes the following: ASUS AE8N-E Motherboard (NVIDIA nForce 4 Ultra Chipset) AMD Athlon 64 3800+ Processor OCZ PC3200 Gold Edition 1GB Memory EVGA GeForce 6600 PCI-Express x16 Video Card CentOS 3.7 The video card wasn't detected and I had to use the VESA driver (generic) when I installed CentOS 3.7. As this is the first time I've used a NVIDIA video card

For using SSDs: Are there any format/mount parameters that should be set for using btrfs on SSDs (other than the "ssd" mount option)? General questions: How long is the ''delay'' for the delayed alloc? Are file allocations aligned to 4kiB boundaries, or larger? What byte value is used to pad unused space? (Aside: For some, the erased state reads all 0x00, and for

Now the test for the Vertex 2 Pro. This was fun. For more explanation please see the thread "Crucial RealSSD C300 and cache flush?" This time I made sure the device is attached via 3GBit SATA. This is also only a short test. I''ll retest after some weeks of usage. cache enabled, 32 buffers, 64k blocks linear write, random data: 96 MB/s linear read, random data: 206 MB/s linear

I recently got a new SSD (ocz vertex LE 50gb) It seems to work really well as a ZIL performance wise. My question is, how safe is it? I know it doesn''t have a supercap so lets'' say dataloss occurs....is it just dataloss or is it pool loss? also, does the fact that i have a UPS matter? the numbers i''m seeing are really nice....these are some nfs tar times before

Hi, In my LAN, I have a debian server where samba 3.0.7-1 is intalled and act as a PDC for my windows os suite. I have a printer connected to my computer and I have share it which work find for my windows without problem. Now, on the other part on my network, I have about 10 Mac OS computer (8.2 & 9.2 series). On my debian server i have install netatalk in order to be able to share files

For some reason, parts of my system are now slowing down to an agonizing crawl from time to time. At first it was my VMWare Server 1.04, which became such a pain that I rebooted. Then, it looked like it was a network-induced thing because the prime culprit was SeaMonkey, particularly with multiple tabs open. I did an ifdown and ifup on my NIC and that seemed to help for a while. But then it

One thing I''ve been confused about for a long time is the relationship between ZFS, the ARC, and the page cache. We have an application that''s a quasi-database. It reads files by mmap()ing them. (writes are done via write()). We''re talking 100TB of data in files that are 100k->50G in size (the files have headers to tell the app what segment to map, so mapped chunks

hi everybody I'd imagine this topic must have been covered, yet I've failed to find any really helpful and a solid howto/examples of how to pass-through a sata disks. currently I'm having this in my xml: <hostdev mode='subsystem' type='scsi' managed='no'> <source> <adapter name='scsi_host4'/>

Earlier this evening, I had the interesting experience of shutting down my machine (because of that lp out-of-sync problem, discussed elsewhere), and watching it not come back up. I admit that I changed out one of my DVD writers for another one, but I don't understand how that could have had any effect on this: When I restarted the machine, it came up to the point where it normally shows:

nice time, Xen community. my DomU has very slow Disk performance, despite the usage of SSD''s. Maybe somebody can give some good tips to accelerate, or point out my mistakes.
