60device nodes. 61The 62.Nm aacp 63device enables the SCSI pass-thru interface and allows devices connected 64to the card such as CD-ROMs to be available via the CAM 65.Xr scsi 4 66subsystem. 67Note that not all cards allow this interface to be enabled. 68.Pp 69The 70.Pa /dev/aac? 71device nodes provide access to the management interface of the controller. 72One node exists per installed card. 73The aliases 74.Pa /dev/afa? 75and 76.Pa /dev/hpn? 77exist for compatibilty with the Dell and HP versions of management tools, 78respectively. 79If the kernel is compiled with the 80.Dv COMPAT_LINUX 81option, or the 82.Pa aac_linux.ko 83and 84.Pa linux.ko 85modules are loaded, the 86Linux-compatible 87.Xr ioctl 2 88interface for the management device will be enabled and will allow 89Linux-based management applications to control the card. 90.Ss Tuning 91The read-only sysctl 92.Va hw.aac.iosize_max 93defaults to 65536 and may be set at boot time to another value via 94.Xr loader 8 . 95This value determines the maximum data transfer size allowed 96to/from an array. 97Setting it higher will result in better performance, 98especially for large sequential access patterns. 99.Em Beware : 100internal limitations 101of the card limit this value to 64K for arrays with many members. 102While it may be safe to raise this value, this is done 103.Em at the operator's own risk . 104Note also that 105performance peaks at a value of 96K, 106and drops off dramatically at 128K, 107due to other limitations of the card. 108.Sh HARDWARE 109Controllers supported by the 110.Nm 111driver include: 112.Pp 113.Bl -bullet -compact 114.It 115Adaptec AAC-364 116.It 117Adaptec SAS RAID 4000SAS 118.It 119Adaptec SAS RAID 4005SAS 120.It 121Adaptec SAS RAID 4800SAS 122.It 123Adaptec SAS RAID 4805SAS 124.It 125Adaptec SATA RAID 2020SA ZCR 126.It 127Adaptec SATA RAID 2025SA ZCR 128.It 129Adaptec SATA RAID 2026ZCR 130.It 131Adaptec SATA RAID 2410SA 132.It 133Adaptec SATA RAID 2420SA 134.It 135Adaptec SATA RAID 2610SA 136.It 137Adaptec SATA RAID 2620SA 138.It 139Adaptec SATA RAID 2810SA 140.It 141Adaptec SATA RAID 2820SA 142.It 143Adaptec SATA RAID 21610SA 144.It 145Adaptec SCSI RAID 2020ZCR 146.It 147Adaptec SCSI RAID 2025ZCR 148.It 149Adaptec SCSI RAID 2120S 150.It 151Adaptec SCSI RAID 2130S 152.It 153Adaptec SCSI RAID 2130SLP 154.It 155Adaptec SCSI RAID 2230SLP 156.It 157Adaptec SCSI RAID 2200S 158.It 159Adaptec SCSI RAID 2240S 160.It 161Adaptec SCSI RAID 3230S 162.It 163Adaptec SCSI RAID 3240S 164.It 165Adaptec SCSI RAID 5400S 166.It 167Dell CERC SATA RAID 2 168.It 169Dell PERC 2/Si 170.It 171Dell PERC 2/QC 172.It 173Dell PERC 3/Si 174.It 175Dell PERC 3/Di 176.It 177Dell PERC 320/DC 178.It 179HP ML110 G2 (Adaptec SATA RAID 2610SA) 180.It 181HP NetRAID 4M 182.It 183IBM ServeRAID 8i 184.It 185IBM ServeRAID 8k 186.It 187ICP ICP5085BR SAS RAID 188.It 189ICP ICP9085LI SAS RAID 190.It 191ICP ICP9047MA SATA RAID 192.It 193ICP ICP9087MA SATA RAID 194.It 195ICP ICP9014RO SCSI RAID 196.It 197ICP ICP9024RO SCSI RAID 198.It 199Legend S220 200.It 201Legend S230 202.El 203.Sh FILES 204.Bl -tag -width ".Pa /dev/aacd?" -compact 205.It Pa /dev/aac?
