History

TMS was founded in 1978 in Houston, Texas by Holly Frost to address a need in seismic processing for the oil and gas industry. The company's first product, the CMPS was a 16 Kilobyte (KB) custom SSD designed for Gulf Oil.{{cite web|url=https://www.micron.com/-/media/client/global/documents/products/white-paper/history_of_digital_storage_wp.pdf|title=History of Digital Storage| last=Klein| first=Dean| publisher=Micron Technology, Inc.| accessdate=2020-03-31| date=2008-12-15}}{{cite web|url=https://docplayer.net/24419177-Time-matters-k-d-polzin-flashsystems-sales-specialist-south-central.html|title=Time Matters| last=Polzin| first=K.D.| publisher=IBM| accessdate=2020-03-31}}

= SAM product line =

Around 1988, TMS designed and sold hundreds of SAM-600/800 (Shared Attached Memory) storage enclosures mainly to the United States Department of Defense. These enclosures used 128 Megabytes (MB) of Dynamic random-access memory (DRAM) for data storage and several high-speed Emitter-coupled logic (ECL) inputs and outputs for data transfer. These systems were mainly used to acquire and analyze signals in real time.{{cite web|title=TMS History of Working With the US DoD| last=Frost| first=Holly| url=https://www.storagesearch.com/tms-history-dod.pdf|publisher=Texas Memory Systems |accessdate=2020-03-31 |date=September 2010}}

When the 1980s oil glut caused disruption in the oil and gas industry, TMS shifted focus away from SSDs and onto Digital signal processing products. The previously-designed SAM storage systems were enhanced by adding in a custom designed DSP board. Prior to this added DSP capability, to analyze a signal, a user would have to send the signal to the SAM storage for staging, engage a separate system to perform digital signal processing, then store the result back to the SAM system for analyzing. Adding the DSP processor into the storage system itself meant that the data could be stored, processed, and analyzed all within the SAM system itself, relieving the host systems from processing duties. With this change in product focus, the SAM product line became known for DSP more than for SSD. The company would release more DSP systems under the SAM brand name in the 1990s: The SAM-2000 (1990), the SAM-300/350, and the SAM-450 (1997). The SAM-300, a 512 MB Solid State Disk, is notable as being a reference high-speed data store to optimize and benchmark other bottlenecks in computing systems, such as Network File System (NFS) and Local area networks (LANs), as other storage media at the time were not fast enough to expose these bottlenecks.{{cite journal |last1=Faber |first1=Theodore |title=Optimizing Throughput in a Workstation-based Network File System over a High Bandwidth Local Area Network |journal=ACM SIGOPS Operating Systems Review |date=January 1998 |volume=32 |issue=1 |pages=29–40 |doi=10.1145/280559.280565 |s2cid=17728725 |url=https://dl.acm.org/doi/10.1145/280559.280565 |accessdate=10 April 2020|url-access=subscription }}

In 2004, TMS partnered with StarGen (later acquired by Dolphin Interconnect Solutions) to integrate the SAM-650 DSP system with the StarFabric switched interconnect. The solution would support military-grade embedded applications by providing 192 Gigaflops of processing performance and 16 gigabits of bandwidth.{{cite web | url=https://www.militaryaerospace.com/communications/article/16710400/in-brief | title=Texas Memory Systems and StarGen join hands on embedded applications | access-date=2021-02-16}}

While the company was developing SAM systems that attached to multiple hosts, it also started developing DSP solutions on PCI cards to address the single-host market. The XP-15, XP-30, XP-35, and XP-100 products were released to the market and were architecturally modeled after the SAM systems. The XP-30 and XP-35 utilize the TM-44 DSP, and the XP-100 utilize the TM-100 DSP.{{cite web |url=http://www.ramsan.com/products/specifications/37 |title=DSP ASIC |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120420102824/http://www.ramsan.com/products/specifications/37 |archive-date=2012-04-20}} Both of these DSP chips were custom designed ASICs from TMS.{{cite web |url=http://ramsan.com/products/digital-signal-processing/xp-30 |title=XP-30 |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120509085208/http://ramsan.com/products/digital-signal-processing/xp-30 |archive-date=2012-05-09}}{{cite web |url=http://ramsan.com/products/digital-signal-processing/xp-35 |title=XP-35 |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120509085300/http://ramsan.com/products/digital-signal-processing/xp-35 |archive-date=2012-05-09}}{{cite web |url=http://ramsan.com/products/digital-signal-processing/xp-100 |title=XP-100 |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120509082716/http://ramsan.com/products/digital-signal-processing/xp-100 |archive-date=2012-05-09}}

In 2000, TMS started working on a new line of SSD products, the SAM-500/520, that would feature standard interfaces and protocols such as Fibre Channel. The SAM-520 was the first SSD product from TMS to use the RamSan brand. It featured 64 Gigabytes (GB) of DRAM for user data storage and up to 15 1 Gb/s Fibre Channel interfaces.

TMS officially entered the commercial storage market{{cite web |url=http://ramsan.com/company/pressReleases/138 |title=Texas Memory Systems Enters Commercial Storage Market |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610111138/http://ramsan.com/company/pressReleases/138 |archive-date=2012-06-10| date=2001-05-10}} on April 10, 2001 with the announcement of the RamSan-210 which featured up to 32 GB of DRAM for user data storage, 4 Fibre Channel ports and promised 200,000 IOPs in a 2U rack-mountable enclosure. In order to assure that the user data written to DRAM would be persistent, in addition to writing user data to DRAM, the 210 also wrote user data to two mirrored hot swappable hard disk drives, a feature dubbed Triple-Mirror mode.{{cite web|url=http://www.eweek.com/storage/storage-unit-delivers-high-performance|title=Storage Unit Delivers High Performance| last=Baltazar| first=Henry| publisher=eWeek| accessdate=2020-03-31| date=2003-02-03}} It also included redundant uninterruptible power supplies which would power the unit for a short time during a brownout, and allow the system to safely shut down in case of a total power loss.{{cite web |url=http://ramsan.com/company/pressReleases/140 |title=Texas Memory Systems Launches the RamSan 210 Solid State Disk |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610115219/http://ramsan.com/company/pressReleases/140 |archive-date=2012-06-10| date=2001-04-10}}

A product refresh followed on November 11, 2002 with the announcement of the RamSan-220 at Oracle OpenWorld in San Francisco, USA. The product doubled the Fibre Channel interface speed to 2 Gbps{{cite web |url=http://ramsan.com/company/pressReleases/123 |title=Texas Memory Systems Announces General Availability of the RamSan-220 |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610110359/http://ramsan.com/company/pressReleases/123 |archive-date=2012-06-10| date=2002-11-11}} and added a new mode of operation called DataSynch. DataSynch mode kept the hard disk drives offline and sent the read and write operations to memory only. In a power outage, the data from memory would be flushed to disk. TMS would later release a 1 Terabyte (TB) solid state disk solution called Tera-RamSan on February 26, 2003 which was composed of 32 RamSan-220 units spread across two racks. The solution would consume 5 KW of power, support up to 2,000 Logical unit numbers (LUNs), and service over 2 million IOPs. A monitoring software dubbed Tera-RamSan at a Glance would allow the user to see system level status at a glance.{{cite web |url=http://ramsan.com/company/pressReleases/121 |title=Texas Memory Systems Announces the Tera-RamSan |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610110603/http://ramsan.com/company/pressReleases/121 |archive-date=2012-06-10| date=2003-02-26}}

On July 1, 2003 TMS announced the follow on RamSan-320. This product increased the height of the enclosure to 3U and added a third hard disk drive now in RAID-3 to backup user data. It provided up to 64 GB of DRAM for user data storage, up to eight 2 Gbps Fibre Channel ports, and increased the performance up to 250,000 IOPs. It also included a new optional patent-pending feature called Active Backup.{{cite patent |country=US |number=2005097288A1 |status=application |title=System and method for monitoring and non-disruptive backup of data in a solid state disk system |pubdate=2005-05-05 |fdate=2003-10-30 |inventor=Holzmann, Richard |assign1=Texas Memory Systems Inc}} With Active Backup enabled, reads and writes would go only to memory just like DataSynch mode, but a background task would continually backup the data stored in memory to the hard disk drives offering the benefit of always having the user data backed up similar to Triple-Mirror mode.{{cite web |url=http://ramsan.com/company/pressReleases/120 |title=The World's Fastest Storage From Texas Memory Systems Boosts Application Performance Up To 25X |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610111330/http://ramsan.com/company/pressReleases/120 |archive-date=2012-06-10| date=2003-07-01}} Three weeks later, on July 29, 2003 TMS announced the RamSan-330 which included the same exact specifications as the 320, but optimized for a new use case. The 330 could be connected to servers, switches, and storage and would be transparent to the host operating system. It would automatically cache frequently accessed blocks, improving read and write performance of any attached storage. It offered user-configurable write-through, write-back, and read-ahead cache modes.{{cite web |url=http://ramsan.com/company/pressReleases/118 |title=Texas Memory Systems Launches Fastest RAID Cache Ever |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610110355/http://ramsan.com/company/pressReleases/118 |archive-date=2012-06-10| date=2003-07-29}} The 330 was demonstrated accelerating a Digi-Data STORM at CeBIT on March 22, 2004.{{cite web |url=http://ramsan.com/company/pressReleases/111 |title=Solid State Disks to take CeBIT by STORM |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610111353/http://ramsan.com/company/pressReleases/111 |archive-date=2012-06-10| date=2004-03-16}} The 320 was refreshed and released as the RamSan-325 on November 9, 2004, and doubled the available capacity up to 128 GB.{{cite web |url=http://ramsan.com/company/pressReleases/104 |title=Texas Memory Systems Doubles The Capacity Of The "World's Fastest Storage" With Its New RamSan-325 Solid State Disk |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610115557/http://ramsan.com/company/pressReleases/104 |archive-date=2012-06-10| date=2004-11-09}}

The product line was expanded with the addition of a new 1U entry level RamSan-120 on December 7, 2004. The 120 implemented the DRAM in a RAID configuration to increase reliability, and was only offered in an 8 GB configuration. It delivered 70,000 IOPs and up to 400 MB/s bandwidth{{cite web |url=http://ramsan.com/company/pressReleases/103 |title=Texas Memory Systems Introduces 400 MB/s Entry-Level Solid State Disk |access-date=2020-03-31 |archive-url=https://web.archive.org/web/20120610111130/http://ramsan.com/company/pressReleases/103 |archive-date=2012-06-10| date=2004-12-07}}

On December 21, 2011, shortly after announcing their first high availability (HA) SSD product, the RamSan-720, TMS announced that they were putting themselves up for sale. The company was looking to be acquired by a large IT company such as EMC Corporation, Hewlett-Packard, IBM, Oracle Corporation or NetApp. This coincides with a general consolidation in the industry such as SanDisk's acquisition of Pliant earlier in the year, a series of run-ups to IPO announcements such as Violin Memory, as well as new startups such as Pure Storage entering the market.

Less than one year later, on August 16, 2012, IBM announced they had entered into a definitive agreement to acquire TMS. The details of the deal were not disclosed. IBM planned to invest in and support the existing TMS product portfolio and integrate TMS technologies into a variety of solutions including storage, servers, software, and PureSystems offerings. At the time of the announcement, TMS employed approximately 100 people. The acquisition was completed on October 1, 2012, and the TMS products, services, and employees were integrated into the IBM Systems and Technology Group (STG).{{cite web |url=https://www-03.ibm.com/press/us/en/pressrelease/38997.wss |archive-url=https://web.archive.org/web/20121003000614/http://www-03.ibm.com/press/us/en/pressrelease/38997.wss |url-status=dead |archive-date=October 3, 2012 | title=IBM Announcement|publisher=IBM|accessdate=2020-03-31}}
