DISCLAIMERS
Drive Usage
:
Sonnet Technologies has qualified and specifies Enterprise/RAID
edition hard drives for use in Fusion storage systems. These drives
were chosen for their superior performance, error handling, and
reliability characteristics, especially when used in RAID groups.
One important difference between Enterprise/RAID edition hard
drives and standard hard drives is how quickly each type handles
read errors—Enterprise/RAID edition hard drives attempt to
recover from errors for just a few seconds, while standard hard
drives may take minutes. Because RAID controller cards and soft-
ware-based RAID schemes allow only a very short time for drives
to recover before dropping them from the RAID group, hard
drive manufacturers recommend against using standard hard
drives in RAID storage systems. Enterprise/RAID edition hard
drives also feature improved vibration characteristics that influ-
ence and support storage reliability.
Only use Enterprise/RAID
edition hard drives in your Fusion storage system to ensure
system reliability and performance. Standard drives may not
be supported and may degrade system reliability and perfor-
mance. Sonnet has qualified and recommends the following
hard drives:
• 500GB Hitachi Deskstar E7K500, model #HDS725050KLA360
• 500GB Hitachi Ultrastar A7K1000, model #HUA721050KLA330
• 500GB Seagate Barracuda ES, model #ST3500630NS
• 500GB Maxtor MaXLine Pro 500, model #7H500F0
• 750GB Hitachi Ultrastar A7K1000, model #HUA721075KLA330
• 750GB Seagate Barracuda ES, model #ST3750640NS
• 1TB Hitachi Ultrastar A7K1000, model #HUA721010KLA330
Creating RAID Volumes Under Windows
:
Creating RAID volumes under Windows requires dynamic disk
storage, a formatting option available with Windows Server
2003 SP1, Windows XP Professional (32- and 64-bit versions), or
Windows Vista Enterprise or Ultimate (32- and 64-bit versions).
In order to create RAID volumes larger than 2TB, you must do
one of the following:
• Use the software configuration tools included with the Fusion
storage to create volumes up to 2TB, concatenate (link together
in a virtual chain) the volumes, and then format as NTFS.
• Use GPT formatting. Note that drives and volumes with GPT
formatting are not visible to any version of Windows XP
Professional, nor to the 32-bit version of Windows Server 2003
SP1.
