Erasure codes

Is HAMMER ever going to have a network based RAID5? Basically implement Erasure Codes?

HAMMER question

Hello, I was taking a peek at http://en.wikipedia.org/wiki/OneFS_distributed_file_system and curious if HAMMER will ever have features like this. TIA

is hammer for us

I am a student doing fluid dynamics research. We generate a lot of data (close to 2TB a day). We are having scalability problems with NFS. We have 2 Linux servers with 64GB of RAM, and they are serving the files. We are constantly running into I/O bottle neck problems. Would hammer fix the

Re: is hammer for us

The I/O bottleneck is coming from the disk subsystem and network. I was wondering if HAMMER can do parallel filesystem implementation similar to GPFS or Lustre. Also, the reads/writes are random access there is very little sequential streaming, but the files are large.Each file is around 30GB

Cool projects. I am rooting for Add redundant data storage to the HAMMER file system. Go Simon :-) On Tue, Mar 3, 2009 at 7:39 AM, Bill Hacker w...@conducive.org wrote: Sdävtaker wrote: It will be amazing if someone can get FreeBSD-UFS mountable (at least for read). I didn't realize

HAMMER and RAID 5

I was wondering if HAMMER will ever have network based RAID 5. After researching several file systems it seems HAMMER is probably the closest to achieve this problem and will make HAMMER a pioneer. Any thoughts or ideas? TIA

Hammer question

I am very intrigued with the HAMMER filesystem. I am a heavy Linux user and at work we use Linux exclusively. I was curious how hammer manages dynamic inodes. On ext3 we pre create inodes which is a fixed amount. How is hammer doing this? Sorry if this is a newbie question. I asked the same

Re: Hammer question

Thankyou. I will start dust of my CS books to start looking into Btrees. On Tue, Feb 24, 2009 at 9:58 PM, Matthew Dillon dil...@apollo.backplane.com wrote: :I am very intrigued with the HAMMER filesystem. I am a heavy Linux :user and at work we use Linux exclusively. I was curious how hammer
