hail,
I have a soekris running an atom and 2GB RAM and ZFS using 7 drives, small capacity though, to
test and study if I can make my home server this box and this way. It will be a simple server,
three users tops.
I followed the handbook and made the geli step on the disks:
Geom name: label/zfs1.eli
State: ACTIVE
EncryptionAlgorithm: AES-XTS
KeyLength: 128
Crypto: software
UsedKey: 0
Flags: NONE
KeysAllocated: 38
KeysTotal: 38
Providers:
1. Name: label/zfs1.eli
Mediasize: 160041881600 (149G)
Sectorsize: 4096
Mode: r1w1e1
Consumers:
1. Name: label/zfs1
Mediasize: 160041885184 (149G)
Sectorsize: 512
Mode: r1w1e1
all disks are this way (just 4 disks are on geli zfs).
would it be faster, if I had geli over zfs, and not the other way (as is now) ?
my performance is too low (I know the hardware is not that much, but I compared it to a friend's
arm based AP-Router gadget and my setup is when much equal. I have 1.6 GHz Atom and 2GB ram, he
has not half this ... I know can't compare arm and x86 clock for clock ...)
I'll try to run geli on single disk, to see how much ZFS is impacting on performance, but, is
there any other way around ? All I want is RAID5, and FreeBSD has not developed RAID5 from GEOM
(AFAIK) since a long time. ZFS is the way people go in recent years.
suggestions are welcome, just want to upgrade my old 8.0 BETA3 using geom mirror/stripe to a newer
approach that would be supported by FreeBSD.
I have an external enclosure for 4 SATA disks (port multiplier included) using 4 disks, another
port multiplier 5x1 using now 3 disks, and:
ahci1@pci0:13:0:0: class=0x010601 card=0x10601b21 chip=0x06121b21 rev=0x01 hdr=0x00
vendor = 'ASMedia Technology Inc.'
class = mass storage
subclass = SATA
with two eSATA to the Port Multipliers.
thanks,
matheus
