Disks and Filesystems ===================== Number of Usable Description Disks Size ----------- ------- ---------- This set of 48 disks is divided into 6 8-disk RAID-0 groups 48 13.4 TB that are each exported as a single LUN. All data file systems reside on these disks. This single boot disk is for system use only. 1 80.0 GB Total 49 13.4 TB Number of Filesystems 6 Total Exported Capacity 13.4 TB Filesystem Type HFS+ Journaled Filesystem Creation Options Default Filesystem Config Each filesystem uses one LUN with 64K RAID0 stripes, 8 drives per file system. Fileset Size 1602.2 GB Each filesystem uses one LUN using HFS+ Journaled's default configuration. The hardware RAID deviates from its defaults using ReadCache and WriteBack on each file system, and each controller is set to have Host Cache Flushing disabled. All other hardware RAID settings are the default, including using 64KB stripe size. The fibre channel RAID is direct attached to the Xserve. Network Configuration ===================== Item Number of No Network Type Ports Used Notes ------ ------------ ------------- ----- 1 Gigabit Ethernet 2 Included motherboard ethernet ports 2 Gigabit Ethernet 2 PCI-Express ethernet add-in card. Network Configuration Notes --------------------------- All network interfaces were connected to a Linksys SRW2024 switch. Benchmark Network ================= Sets of two clients were attached to a single subnet, 3 subnets total. Interconnect was via a Linksys SRW2024 gigabit switch.

Stable Storage ============== 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. The storage array has dual storage processor units that work as an active-active failover pair. When one of the storage processors or battern units are off-line, the system turns off the write cache and writes directly to disk before acknowledging any write operations.
