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)

NAME
ahci - Advanced Host Controller Interface SATA controller driver
SYNOPSIS
sata@unit-address
DESCRIPTION
The ahci driver is a SATA framework-compliant HBA driver that supports SATA HBA controllers that are compatible with the Advanced Host Con-
troller Interface 1.0 specification. AHCI is an Intel-developed protocol that describes the register-level interface for host controllers
for serial ATA 1.0a and Serial ATA II. The AHCI 1.0 specification describes the interface between the system software and the host con-
troller hardware.
The ahci driver currently supports the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host
Controller Interface 1.0 specification. Note that while the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers support standard
SATA features, the ahci driver currently only supports hard disk, ATAPI SATA DVD, hotplug and NCQ (Native command queuing). Port multiplier
and power management are not yet supported.
CONFIGURATION
The ahci module contains no user configurable parameters.
FILES
/kernel/drv/ahci
32-bit ELF kernel module (x86).
