[zfs-discuss] ZFS memory recommendations
I am currently doing research on how much memory ZFS should have for a storage server. I came across this blog http://constantin.glez.de/blog/2010/04/ten-ways-easily-improve-oracle-solaris-zfs-filesystem-performance It recommends that for every TB of storage you have you want 1GB of RAM just for the metadata. Is this really the case that ZFS metadata consumes so much RAM? I'm currently building a storage server which will eventually hold up to 20TB of storage, I can't fit in 20GB of RAM on the motherboard! -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Ideal SATA/SAS Controllers for ZFS
My work has bought a bunch of IBM servers recently as ESX hosts. They all come with LSI SAS1068E controllers as standard, which we remove and upgrade to a raid 5 controller. So I had a bunch of them lying around. We've bought a 16x SAS hotswap case and I've put in an AMD X4 955 BE with an ASUS M4A89GTD Pro as the mobo. In the two 16x PCI-E slots I've put in the 1068E controllers I had lying around. Everything is still being put together and I still haven't even installed opensolaris yet but I'll see if I can get you some numbers on the controllers when I am done. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
