the13bats :
I have made several comps and just had this dell t7500 given to me,
I want to use it as a pc not a server,
On the motherboard
It has 3 sata connectors and 4 connectors called sas, in the bios it has options to enable or disable sas,
At the moment i have the sas set to disable and my os on a hdd plugged into a sata connector, works great,
I would like to add 3 or 4 hdds for storage, pix on one tunes on another etc,
Can the sas connectors be used for those storage drives each with a separate drive letter,
Thanks for cluing me in on this sas thing,
Cheers,
B
the 13bats,
I'm a bit confused as to the total number of drives and as to SATA and/or SAS you intend to use but Form me the principal issue is that the T7500 is SATAII 3GB/s.
But there is a cure!
Consider adding a
PERC H310 SATA/SAS RAID controller.
PERC H310 technical specification
Solution provided
Low-cost, green SATA+SAS RAID solution for high-density servers (1U or 2U) and workstations with the flexibility
to use both SATA and SAS hard drives, solid state drives, and pass-through drive configurations
Physical dimensions
167.6mm (6.6in) x 64.4mm (2.5in) (low profile)
Connectors
Two x4 internal mini-SAS SFF8087
Maximum number of Physical devices:
Non-RAID: 32
RAID 0: 16 per volume
RAID 1: 2 per volume plus hot spare
RAID 5: 16 per volume
RAID 10: 16 per volume
RAID 50: 16 per volume
Host bus type
8-lane, PCI Express 2.0 compliant
Data transfer rates
Up to 6Gb/s per port
SAS controller
LSISAS2008
Key RAID data protection
Features
RAID levels 0, 1, 5, 10, 50:
Selectable logical drive as boot drive
Consistency check
Fast initialization for quick array setup
Native command queuing
Staggered spin-up for SATA drives
Hot-plug support
Global hot-spare support
Online Capacity Expansion (OCE)
Online RAID Level Migration (RLM)
PowerPC 440
Automatic rebuild of hot-spare drives
Auto resume during array rebuild
Greater than 2TB logical drive support
Soft bad block management
Error recovery support
DDF compliant configuration on disk
S.M.A.R.T. support
Patrol read for media scanning and repairing
Physical disk power management (Dimmer Switch™)
So, the H310 provides extreme versatility in the drives department. I added one to a Precision T5500 (see below). The performance also improved significantly: without changing the drives: using a Samsung 840 240GB and WD Black 1TB, the Passmark disc score changed from
2122 to
2649. These are sold on Ebay US currently for $59-$80. If you do try it, be sure that it is the low profile version that includes the desktop PCIe slot bracket. The server model doesn't and they cost $10.
Yes, you can have dozens of 6GB/s drives and run out of letters!
I recommend running Passmark Performance Test- there's a free trial version and before-and after- follow the improvements to the T7500.
If' you're gaming, have a look at the CPU with the highest single=thread performance, the Xeon X5687 - 3.6 /3.86GHz
