hardware

cpu must be compatable see https://illumos.org/hcl/

operating system install

http://www.napp-it.org/doc/downloads/napp-it.pdf

there are a few install options. I used this option:

4. OS Installation options

4.1 manual barebone installation from USB (use this per default)

• Download usb-dd file from http://omnios.omniti.com/wiki.php/Installation

access web page

http://<IP>:81/cgi-bin/admin.pl

Info: First login: admin, no password; delete napp-it.cfg to get defaults

Please do not disable Javascript. For realtime monitoring you need a HTML5 websocket capable browser like a newer Firefox or Google Chrome. Logins are valid for current day on all appliances with the same password. It is suggested to use a secure SAN or management network.

zpools

ten 480GB ssd drives

https://forum.proxmox.com/threads/shared-storage-suggestion-for-a-5-node-cluster.26727/

Mir: I would suggest 2 pools:

1. Raid10 or striped mirror pool (2x2 disks should be sufficient) for I/O intensive servers like database servers.

2. raidz2 pool (the remaining 6 disks) for the rest

see zil [ write-log ] section at https://www.napp-it.org/manuals/concept_en.html

when in doubt use a write-log. see notes and tests at iscsi/tests or forum search.

napp-it refers to zil as 'write-log' << TBD check this

mirror

set up 4 drive mirror

1- create pool 2 drive mirror

2- extend pool with 2 drive mirror

to start do not use a write-log [ zil ] write-log

my 1-st tests show similiar speed to raidz1 + zil .

raidz1

5 ssd drives

1 write-log ssd Intel super one << put model numbers TBD

with a write-log drive vzrestore was 22 times faster then without.

cli adjustments

• there probably is a way to do this from napp-it

# needed cli for atleast no atime:
zfs set atime=off tank
zfs set compression=lz4 tank

configure omnios

Network mtu 9000

• from http://www.saqr.org/index.php?option=com_content&view=article&id=100:change-default-mtu&catid=51:solaris&Itemid=72

vi /kernel/drv/ixgbe.conf
default_mtu = 9000;

then reboot

check result

root@sys4:/root#  dladm show-linkprop -p mtu ixgbe0
LINK         PROPERTY        PERM VALUE          DEFAULT        POSSIBLE
ixgbe0       mtu             rw   9000           1500           1500-15500
