| Description | Number of Disks | Usable Size |
|---|---|---|
| This set of 64 disks is divided into 16 4-disk RAID-0 groups that are each exported as a single LUN. All data file systems reside on these disks. | 64 | 13.4 TB |
| This single boot disk is for system use only. | 1 | 80.0 GB |
| Total | 65 | 13.4 TB |
| Number of Filesystems | 16 |
|---|---|
| Total Exported Capacity | 1.1 TB |
| Filesystem Type | HFS+ Journaled |
| Filesystem Creation Options | Default |
| Filesystem Config | Each filesystem uses one LUN with 64K RAID0 stripes, 4 drives per file system. |
| Fileset Size | 2160.3 GB |
Each filesystem uses one LUN using HFS+ Journaled's default configuration. The hardware RAID deviates from its defaults using ReadCache and WriteBack, and cache mirroring disabled. All other hardware RAID settings are the default, including using 64KB stripe size. The Xserve fibre channel is connected to the SANbox 5600, as are the RAID controllers.

| 2 | Gigabit Ethernet | 4 | PCI-Express quad ethernet add-in card. |
All network interfaces were connected to a Linksys SRW2024 switch.
Sets of two clients were attached to a single subnet, 6 subnets total. Interconnect was via a Linksys SRW2024 gigabit switch.

| Hardware RAID system main memory, with 72-hour battery backup | 2 | 2 | 4 | NV |
| Grand Total Memory Gigabytes | 20 |
The write cache is backed up with a battery unit able to retain the write cache for 72 hours in the event of a power failure.
NFS stable write and commit operations are not acknowledged until after the RAID storage system has acknowledged that the related data stored at least in non-volatile RAM. When battery units are off-line, the system turns off the write cache and writes directly to disk before acknowledging any write operations.
Default configuration, except as listed in Server Tunings.
Spotlight indexing was disabled.
