Dell PowerVault 715N (Rackmount NAS Appliance) - Manual (Page 11)

External Cache Memory Test — identifies and tests the external cache memory, and then performs a
random pattern test within the range of the cache memory size to detect cache memory problems.
Quick Memory Test — quickly verifies that the entire installed memory can be accessed.
System Board
DMA Controller Register Tests — a series of read and write tests on the memory address registers and page
registers of DMA controllers 1 and 2.
Interrupt Controller Test — performs a series of read and write tests on interrupt mask registers and checks for
stray interrupts after masking off all interrupts.
Timer Test — checks the accuracy of the timer count by calibrating it against the periodic interrupt of the Real
Time Clock (RTC).
Real Time Clock Test — checks the regularity of the real time clock interrupt by calibrating it against the timer 0
interrupt.
CMOS Memory Validity Test — checks the validity of the data in CMOS RAM and makes sure that the CMOS RAM
checksums are correct. This test also ensures that the battery is in good condition.
SMBus Test — checks that the System Management Bus (SMBus) works properly. This test consists of the SMBus
general test and the SMB access test.
Hardware Monitoring Tests — reads the values of the following items and checks whether they are in a specified
range. This test monitors the following measurements:
System voltages (2.0-V, 2.5-V or 1.5-V, 5-V, and 12-V)
System fan speed
CPU temperature
IDE Hard Drive
Write Test — checks that the selected IDE hard drive writes data correctly. It writes a pattern of data to the IDE
hard drive, then reads the data it has written. It is a destructive test. This test destroys all data on the tested IDE
hard drive. Initially, the destructive test is hidden. Select Toggle Hidden Test Display to display the test (Write
Test) on the menu. Select Toggle Hidden Test Display again to hide the test.
NOTICE: The IDE HDD Write Test is a destructive and hidden test. When you run this test, it erases all data on the
tested drives.
Read Test — performs sequential and random read operations on the specified part of the IDE drive.
Verify Test — performs sequential and random read and verify operations on the specified part of the IDE drive.
Seek Test — determines the head movement ability of the hard drive over the specified cylinder and head range.
It consists of a sequential seek test and random seek test.
Quick Test — verifies that the software can fully access the selected IDE hard drive. The test reads small blocks of
sectors at the beginning, middle, and end of the hard drive.
Network Controller
CSR Access Test — checks access to the i8255x Control/Status Register through I/O and memory.
Walking Bits Test — performs Walking 1's Test on all valid I/O registers.
Self Test — checks the functionality of the i8255x micromachine, internal registers and internal ROM.
IRQ Test — checks that an interrupt was assigned to the i8255x, and it then forces the controller to generate an
IRQ to see if it is acknowledged properly.
