Windows Server 2008Device and System Logo and Test Requirements Sandy Arthur Program Manager Microsoft Corporation
Windows Server 2008 Logo and Test Goals • Improve reliability, availability, and serviceability of Windows Server 2008 by: • Leveraging new technologies to reduce hardware failure rate. • Enhancing tests to reduce software failure rate. • Address problem areas exposed by OCA, PSS. and other data sources that impact Windows Server 2008 customers’ typical scenarios, usages, and configurations: • Multiple adapters, higher number of CPUs, more RAM, complex drivers such as MPIO, LBFO, TOE, anti-virus, firewall, mirroring, backup, remote management, and so on.
Agenda • Legacy Systems • Server-Specific Device and System Logo Requirements • Server-Specific Device and System Test Requirements • Additional Qualifications • Server System Stress Test
Supported Systems • Supported category for systems will continue to exist: • This is “forward compatibility” from Windows Server 2003 to Windows Server 2008. • Supported option will NOT exist for devices: • All server-qualified devices/drivers must be Server logo’d. • Testing and submission: • Windows Server 2003 SID • Windows Server 2008 Logo Drivers • CHKLogo • 32-bit only systems and devices in the system: • Devices need X64 version for logo and signature. • Catalog display.
Some Server Model Name and Number by Some Manufacturer, Inc.
Server-Specific Device Logo Requirements • All device categories supported for server: • Must be functional in DP-capable systems: • DP-capable systems will become more broadly available over time. • Customer may add arbitrary devices to their DP-capable systems. • Customers will need Hot Add for their virtual Windows instances . • This is functionality that all drivers should have in any case. • Must meet logo requirements that support the above: • Hot Add CPU • Resource Rebalance • Hot Replace Quiescence/Pseudo S4
Server-Specific System Logo Requirements • Requirements different from Windows Vista and different reasons for requirements that are the same. • Security: • BitLocker (if implemented) – Branch Office scenario. • Reliability and availability: • WDT (if implemented) – prevent hung system from losing availability. • WHEA (required). • PCI-E (required June 2008) – provides Advanced Error Reporting and improved availability. • ECC or better (required) – memory errors are a “Top 20” issue for Windows Server 2003 crashes.
Server-Specific System Logo Requirements (continued) • Performance: • HPET (required) – significant performance improvement for applications needing high-resolution timestamps. • GigE or better (required) . • Manageability: • Headless, Remote, OOB (required, but specific implementation is up to vendor). • Power: • Processor power states, if exist, must be exposed to Windows (if implemented). • No S3 requirement (if implemented).
Server Device Test Requirements • All device categories: • Must test with Windows Server 2008, not Windows Vista. • 4-Core, 1-GB system required. • DP Tests : • Hot Add CPU • Resource Rebalance • Hot Replace Quiescence/Pseudo S4 • Storage and networking devices: • 4-Core, 6-GB system required. • Device tests that require pools and the “no-driver” case: • 4-core system for DP testing must include driver and be in pool. • 4-core system for DP testing must be the sole, or first, system in pool for case where no driver is being tested, such as HD testing.
Server System Test Requirements • CHKLogo exam of WHQL signature attribute: • Client signature has different attributes than server. • Many/most of the current Windows Vista tests are “If Implemented” for server: • Will not execute or “false” fail if the device category does not exist in system. • Server-client stress test. • Shutdown/restart: • ~1% of systems fail to shutdown; numerous reasons. • Test can detect power off, dirty shutdown, WDT, and so on.
Additional Qualifications: Definition • There are groups of “If Implemented” requirements in WLP 3.x dealing with hardware functionality not required for logo: • If Implemented features are not required for logo. • If Implemented features that are critical to security or reliability are tested as part of logo qualification, if present: • Security, BitLocker • Reliability, WDT • If Implemented features that provide “additional” functionality beyond what industry standard systems do are tested as “Additional Qualifications”: • Examples: Dynamic Partitioning, Fault Tolerance, and Virtualization. • Vendor may select none, some, or all qualification tests for additional qualifications [AQs]. • Additional qualifications are the way a vendor can: • Qualify their systems functionality with respect to these if implemented” requirements. • Inform customers of this functionality in the Server Catalog.
“If Implemented” System Logo Requirements • FT: • None specific to FT • DP: • Partition isolation • Configuration persistence • Partition “unit” differences between I/O and CPU-RAM • Stability after hot add and replace operations • Partition management, status, and UI • VM: • Windows-compatible virtualization support
“If Implemented” Additional Qualification Tests • Fault tolerant: • “Standard” server system logo test. • Fault-tolerant AQ test. • Test of system ability to “survive” FT set break and resync with no impact on stress clients. • DP: • “Standard” server system logo test. • Dynamic partitioning AQ tests. • Tests of partition Isolation, configuration persistence partition “nit” differences between I/O and CPU-RAM, stability after hot add and replace operations, partition management, status, and UI. • VM: • “Standard” server system logo test. • Virtualization AQ test. • Tests processors for Windows-compatible virtualization support.
Design Considerations • Customer support history of bugs found that the test could have found, but did not. • OEM feedback on past “Test” issues. • Lessons learned from previous kits .
Design Goals • Replay-repro failures more consistently: • Replay log - within the ball park, not an exact science. • Vendor can e-mail log to Microsoft to be replayed in lab. • Hardware and machine names need not be the same. • Stress load on processor and RAM is “appropriate” to system: • Regardless of CPU count or speed, amount of RAM. • Support multiple NICs and HBAs: • Test many configurations at once. • Dynamically add/replace slave clients: • The test no longer automatically fails when a client fails. • Automated setup and cleanup. • Non-HCT mode for vendor use in testing: • Start/stop tests. • Change stress settings through GUI or CLI. • Use in combination with vendor-written tests.
Test Content • CPU, RAM, paged pool, and non-paged pool: • Exercises chipset, buses, processors, and RAM. • Network/Winsock: • Works with TOE or “non-TOE” adapters/drivers. • SQL emulator: • Designed to find corruption issues. • Client-server SMB: • Multiple NICs, networks, and physical layers [GigE, 10GigE, FDDI] possible. • Local file system: • Multiple HBAs, storage and physical layers [SATA, SAS, FC, iSCSI] possible.
Dynamic Load Generation • Workload automatically scales to the number of network and storage adapters found in the system: • Adapters need not be same type, but require “matching” network clients or storage devices. • Network usage is “managed” to average ~40% by throttling clients. • Storage stress provided by single instance of stress per HBA-HD(s) “pair”. • Target stress level for HBA-HD pairs is “100%”. • Achieve the same relative amount of stress on the system, regardless of number or type of processors, or amount of memory: • Test spawns as many processor-specific and memory-specific stress threads as are needed to achieve a predetermined level of processor and memory usage. • Test will terminate those stress threads if the usage level exceeds the predetermined upper range of stress for a period of time. • Target for processor, RAM, and pools usage is 70%.
Server Stress Test Systems Configuration • Server (SUT: Server Under Test) • Client Master : • Cluster/Server harness install point • Standard server SKU • Single process machine • Clients : • 8 clients generating load against SUT • Standard server SKU • Single process machine Network Switch
Server Stress – Tests UI ‘history’ of starts and stops of tests Status of what is happening at the moment
Call To Action • Start testing server device and system DTM at Beta 3. • File bugs with Microsoft WHQL if any issues. • Use server device and system tests to find issues in your own products . • Fix those issues so that tests can be passed at RC for server devices and server RTM for systems without costly delays.
