I'm running glusterfs on CentOS 6.6 two nodes, (the SSD (samsung 840 1TB x2) is RAID 0 on the HP DL380 G6) x2, and trimming is not enable on it by checking /dev/sdb1/xxxxx/discard_max_bytes=0. Do I still need trimming? Somehow my filesystem is fine with 35-30% free space and running very fast.

Nowadays the fastest SSDs achieve read-speeds of between 1500 MB/s to 1900 MB/s. Let's say that two such SSDs in RAID 0 achieve roughly double the throughput, ie 3000 MB/s. That is only half an order of magnitude removed from RAM ((10)^(1/2) * 3000 = 10.000), very broadly speaking.
So for the... (6 Replies)

I have an upgrade path in mind for a new computer that will be stocked with a 2TB SATA 300 hard disk. This is a choice based on information that SATA 300 is not necessarily faster than SATA 600. The upgrade path in a year time or so would then involve the purchase of an SSD that would contain the... (4 Replies)

Hello everybody,
I need to connect a laptop 2.5 SATA hard drive to a Desktop board (which uses 3.5' SATA hard drives). I've tried the connectors and they fit excellent in the 2.5 SATA connectors.
The problem is that the laptop hard drive uses 5v and the PC's power source sends 12v. So, my... (4 Replies)

NAME
arcmsr -- Areca SATA II RAID Controller driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device scbus
device da
device arcmsr
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
arcmsr_load="YES"
DESCRIPTION
The arcmsr driver provides support for the Areca ARC-11xx and ARC-12xx series of SATA II RAID controllers. These controllers feature RAID-0,
1, 3, 5, 6, and 10 and JBOD acceleration for up to 16 SATA drives. Raid level and stripe level migration, online capacity expansion, hot
insertion/removal, automatic failover and rebuild, and SMART are also supported. Access to the arrays is provided via the SCSI CAM /dev/da?
device nodes. A management interface is also present via the /dev/arcmsr? device node. Management tools for i386 and amd64 are available
from Areca.
HARDWARE
The arcmsr driver supports the following cards:
o ARC-1110
o ARC-1120
o ARC-1130
o ARC-1160
o ARC-1170
o ARC-1180
o ARC-1110ML
o ARC-1120ML
o ARC-1130ML
o ARC-1160ML
o ARC-1210
o ARC-1220
o ARC-1230
o ARC-1260
o ARC-1280
o ARC-1210ML
o ARC-1220ML
o ARC-1231ML
o ARC-1261ML
o ARC-1280ML
FILES
/dev/da? Array block device
/dev/arcmsr? Management interface
SEE ALSO
da(4), scbus(4)
HISTORY
The arcmsr driver first appeared in FreeBSD 5.4.
AUTHORS
The driver was written by Erich Chen <erich@areca.com.tw>.
BUGS
The driver has been tested on i386 and amd64. It likely requires additional work to function on big-endian architectures.
