Think compile farms, mail relays with antispam, webservers, databases with parallelisable queries, zfs with compression, VMs, etc. Simply many background processes (dormant zones and services) can require a bit of overhead in context switching (and at a few thousand processes per core this can become a fulltime job of its own); the more cores you have - the smaller hit you get per each. Even if you do not have such loads running fullthrottle all the time, it is possible that the moment you do - more cores can help reach your goals faster in wallclock time. This servers only job will primarily be exposing zvol's as iSCSI LUN's and to a lesser extend shared storage via NFS for virtual servers. I have one now doing the same job running on a 4 core Opteron (3350 HE) and at no time it has been even close to saturate all 4 cores. I think 4 cores should suffice and for only 15W compared to 45w. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael at rasmussen dot cc http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0xD3C9A00E mir at datanom dot net http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0xE501F51C mir at miras dot org http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0xE3E80917 -- /usr/games/fortune -es says: Q: How do you save a drowning lawyer?

[OmniOS-discuss] User/group with CIFS
Hello, in my server (latest stable release) I use netatalk to share files with OS X and I use CIFS (kernel) for Windows. I never noticed until now that the files made by the two operating systems have mismatching and incompatible permissions. This prevents me from modifying or deleting under an operating system the files created with the other one. For example: -rw-r--r-- 1 olaf olaf 469 Aug 2 17:12 scaletta.txt owner@:rw-p--aARWcCos:---:allow group@:r-a-R-c--s:---:allow everyone@:r-a-R-c--s:---:allow -rwx--+ 1 olaf olaf 469 Aug 2 17:12 scaletta2.txt user:olaf:rwxpdDaARWcCos:---:allow group:2147483648:rwxpdDaARWcCos:---:allow The first one was generated by netatalk and correctly shows the permissions according to the user/group I used to login, it also inherited extended ACL according to the parent folder. The second file was created by Windows 8.1, when connected to my server using SERVER@username as login (to be sure I am logging in with a user local to the server), and added strange ACL: user:olaf/group:2147483648 The server is not connected to any AD and I am using a normal workgroup setup. Where can I find some info to understand the issue? is there something obvious I missed? in my configuration? Thanks!

Re: [OmniOS-discuss] User/group with CIFS
Netatalk and Solaris CIFS are incompatible regarding permissions in an AD environment or regarding groups. One problem hides in the + of -rwx--+ 1 olaf olaf 469 Aug 2 17:12 scaletta2.txt This means that there are ACLs defined. While netatalk uses classic Unix permissions (owner/group/everyone), Solaris CIFS works like Windows what means: It uses ACL only, uses Windows SID in AD environments and Windows SMB groups instead of Unix groups. The group:2147483648 is an SMB group that is unknown to netatalk while the group olaf is a Unix group that is unknown to Solaris CIFS. Your options are: 1. Avoid netatalk as it is dead and always a source of problemws. Apple switched to SMB so this is the future. (This is what I did). Currently you have the Problem that Illumos lacks SMB2 and OSX is slow with SMB1. Hope that this will come in the near future to OmniOS as it is in NexentaStor and Solaris 11.3. First tests on Solaris show that smb is there as fast as AFP. 2. Avoid AD, groups and set permissions on Windows only for users or use id mapping This is a workaround 3. Use SAMBA as it rely on Unix permissions as well (For what I use SMB, Solaris CIFS is superieur, so an option that I would avoid) my tip is 1.

At high loads even interrupt processing has a noticeable cost. No Windows© here so antivirus is not an issue;-) No dedub either.
