The '''IBM IntelliStation''' is IBM's professional workstation brand, first released in '''March 1997''' as the successor to the IBM PC Series 360 / 365.<ref>https://en.wikipedia.org/wiki/IBM_IntelliStation</ref> The brand spans two parallel product families: the '''x86 IntelliStation''' line (Intel and AMD CPUs, single- and dual-socket workstations) and the '''POWER IntelliStation''' line (PowerPC 970 and IBM POWER workstations, branded under the IntelliStation umbrella from February 2002 onward, having previously been sold as eServer pSeries).<ref>https://en.wikipedia.org/wiki/IBM_IntelliStation</ref>

The x86 IntelliStation line was discontinued in '''March 2008'''. The POWER IntelliStation line (POWER 185 and POWER 285) was discontinued in '''January 2009'''.<ref>https://en.wikipedia.org/wiki/IBM_IntelliStation</ref> The x86 line passed to Lenovo with the rest of the IBM PC business and was renamed '''Lenovo ThinkStation'''; the POWER line had no Lenovo successor.

== Branding ==

The IntelliStation line is split into four x86 tiers, plus a rack-mount tier, plus the POWER family:

* '''E Pro''' — Entry / single-CPU workstation.
* '''M Pro''' — Midrange / single-CPU (some early submodels are also dual-CPU; e.g. 6889 / 6898).
* '''Z Pro''' — High-end dual-CPU Xeon workstation; one Itanium submodel (Type 6894).
* '''A Pro''' — AMD Opteron workstation (2004 onward).
* '''R Pro''' — Rackmount 1U workstation (rebadged xSeries 330).
* '''POWER''' — PowerPC 970MP and IBM POWER4+ / POWER5+ workstations (Models 185, 265, 275, 285).

Certain M Pro models are near-identical hardware to entry-tier Netfinity servers (Netfinity 1000-class), differing mainly in video, SCSI options and software bundle.<ref>https://en.wikipedia.org/wiki/IBM_IntelliStation</ref>

== x86 Machine Type Table ==

The IBM machine type (MT) is the authoritative key to every IntelliStation. The MT is printed on the rear-panel label (e.g. "Type 6219-23U").

The POWER 185 and POWER 285 were withdrawn on the same day in January 2009 (IBM hardware withdrawal announcement ENUS908-170), ending the IntelliStation brand entirely.<ref>http://www-01.ibm.com/common/ssi/rep_ca/0/897/ENUS908-170/ENUS908-170.PDF</ref>

== Storage and RAID ==

IntelliStation storage controllers track IBM's xSeries roadmap. Generations:

* '''Early''' (6899, 6888, 6893, 6889, 6898) — Adaptec AHA-2940 / AHA-2940 UW / Ultra Wide SCSI on the planar; optional ServeRAID II/3H/4H.
* '''Mid''' (6868, 6850, 6219, 6221) — LSI 1020/1030 Ultra160 / Ultra320 on the planar; optional ServeRAID-4Lx / 4Mx / 5i / 6i.
* '''Late''' (6223, 6217, 9228, 9229) — '''Adaptec-derived ServeRAID HostRAID''' variants: ServeRAID-7e (HostRAID for SATA), ServeRAID-7t SATA, ServeRAID-8e (HostRAID, signed CD).<ref>https://www.ibm.com/support/pages/ibm-serveraid-7e-adaptec-hostraid-drivers-suse-linux-enterprise-server-8-ibm-intellistation-pro-type-6224</ref><ref>https://www.ibm.com/support/pages/serveraid-8e-adaptec-hostraid-support-cd-signed-servers-and-intellistation</ref>

Note: IBM never used the '''LSI "ServeRAID-MR"''' rebranding on IntelliStation; that came in System x post-2007. Driver legacy on IntelliStation is therefore Adaptec-exclusive for ServeRAID, with LSI integrated controllers handled outside the ServeRAID brand. The '''ServeRAID Support CD v7.12.14''' is the standard tool for older ServeRAID controllers.<ref>https://www.ibm.com/support/pages/ibm-serveraid-support-cd-v71214-ibm-system-x</ref>

=== ECAs Found ===

* '''ECA037''' — 9.1 GB and 18.2 GB SCSI HDD firmware update for IntelliStation M Pro Type 6889 / 6897; fixes "HDDs may fail to spin up after power-off" on Adaptec SCSI controllers, or fail completely on ServeRAID / Netfinity FC controllers.<ref>https://www.ibm.com/support/pages/eca037-91gb-and-182gb-scsi-hard-drive-firmware-update-ibm-intellistation-m-pro-type-6889-6897</ref>
* '''ECA036''' — same fix applied to IntelliStation E Pro Type 6893.<ref>https://www.ibm.com/support/pages/eca036-91gb-and-182gb-scsi-hard-drive-firmware-update-ibm-intellistation-e-pro-type-6893</ref>

== Power Supplies ==

Documented PSU ratings:

* '''M Pro 6868''' — 330 W.<ref>https://www.ibm.com/support/pages/specifications-ibm-intellistation-m-pro-type-6868</ref>
* '''A Pro 6217''' — 530 W with Power Factor Correction (PFC).<ref>https://www.ibm.com/support/pages/overview-ibm-intellistation-pro-type-6217</ref>
* '''POWER 285''' — single non-redundant Artesyn PSU, ~300 W typical draw with AIX and 2 disks.<ref>https://sites.google.com/site/rhdisk0/unix/hardware/ibm285</ref>
* '''Other MTs''' — refer to the per-MT Hardware Maintenance Manual.

== Common Faults ==

* '''Capacitor plague''' — the M Pro / Z Pro Pentium 4 / Xeon generation (roughly 2001–2004) is squarely in the timeframe of the Nichicon HM / HN and Rubycon MBZ failures. Z Pro 6221 is community-confirmed as affected.<ref>https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-desktop-motherboards-graphics-cards-and-pc-peripherals/6085-msi-ms-9121-vs-ibm-z-pro-intellistation-6221</ref><ref>https://en.wikipedia.org/wiki/Capacitor_plague</ref> See [[IBM IntelliStation Capacitor Replacement Guide]].
* '''Rubycon MBZ no-bloating failures''' — MBZ has a documented "no-bloating" failure mode and was discontinued by Rubycon in 2011, complicating like-for-like replacement.<ref>https://www.badcaps.net/forum/general-topics/general-capacitor-questions-issues/18044-scary-trend-of-rubycon-mbz-failures-no-bloating</ref>
* '''CR2032 RTC battery dead''' — all generations from 6899 through 9229 use a socketed CR2032 lithium coin cell on the planar; depletion produces the classic '''161 / 162 / 163''' POST cluster.
* '''PSU 5VSB regulator failure''' — common on early-2000s IBM PSUs; presents as "no power on press" with the green standby LED dim or off.
* '''ServeRAID firmware mismatch''' — after a card swap, the ServeRAID firmware on the card must match the firmware level recorded on the drives. Recovery via ServeRAID Support CD.

== Operating Systems ==

* '''x86 IntelliStation''' — Microsoft Windows NT 4.0 Workstation, Windows 2000 Professional, Windows XP Professional, Windows XP x64 Edition, Windows Vista Business; Red Hat Enterprise Linux WS; SUSE Linux Enterprise Workstation. Pre-2003 models were certified for Windows NT 4.0; later models for XP and beyond.
* '''POWER IntelliStation''' — '''AIX 5L 5.2 and 5.3''' was the launch OS for the POWER 285; AIX and '''Linux on POWER''' (SUSE Linux Enterprise Server for POWER, Red Hat Enterprise Linux for POWER) were both supported on the POWER family.<ref>https://redbooks.ibm.com/redpapers/pdfs/redp4135.pdf</ref>

== Pricing ==

The IntelliStation line was priced as IBM business workstations. Representative US launch prices:

* '''Z Pro 6899''' (1997, dual Pentium Pro): $7,500 USD entry config.
* '''M Pro 6868''' (2001, single Pentium III + i840): $3,800 USD entry config.
* '''Z Pro 6221''' (2003, dual Xeon E7505): from $4,200 USD.
* '''POWER 285''' (2005, POWER5+): $10,000+ USD with AIX 5L.
