Just days after reporting dismal server hardware sales, IBM has unloaded its lower-end Intel-based System X servers to Lenovo for $2.3 billion.
Reports of this deal began to circulate eventual July with speculation mounting in recent weeks following the company's launch of its X6 architecture for its System X and Power servers, which industry watchers saw as an attempt to Make its Intel Corp. servers more attractive to potential buyers.
Some analysts believe the deal makes strategic sense for Lenovo, IBM and the respective users of each company.
"Lenovo will be invested in growing the business, users consequently will collect lower expense points and a clearer and more defined product roadmap," said Krista Macomber, hardware analyst with Technology trade Research, Inc., market researchers in Hampton, N.H. "But they will too collect the service and advocate they are used to getting from IBM."
The deal should open up fresh market opportunities for the System X line and IBM's higher-end Power progression as well, according to Macomber. With the System X line gone, the Power progression can pursue fresh market opportunities without "stepping on the toes" of System X, Macomber said.
Initially, some users may be unhappy with the deal and could jump ship.
"There could be some dissent among the more diehard System X customers over the next year or so who could be concerned about support, but overall the defections will be relatively light," Macomber said.
Besides the System X servers, other IBM server products in the acquisition comprise the company's BladeCenter and Flex System blade servers and switches, x86-based Flex integrated systems, NeXtScale and iDataPlex servers, and the blade networking and maintenance operations, according to a company spokesman.
IBM will retain its System z mainframes and Power Systems, both of which had disappointing sales results for 2013, along with its Storage Systems, Power-based Flex servers, and PureApplication and PureData appliances, according to the company.
As portion of the deal IBM and Lenovo will figure a partnership that involves a worldwide OEM and reseller agreement for a compass of IBM products including tall Blue's Storwize disk storage systems.
"This divestiture allows IBM to focus on system and software innovations including cognitive computing, tall data and cloud," said Steve Mills, IBM's senior vice president and group executive, IBM Software and Systems, in a prepared statement.
Earlier this week IBM reported overall server hardware sales for the fourth quarter plummeted 26%, with the System X progression dropping 16%.
For its portion of the deal, Lenovo will assume outright related customer service and maintenance operations for System X products. IBM will provide maintenance delivery on Lenovo's behalf for an undisclosed era of time, according to a company spokesman.
The deal builds on the collaboration between the two companies, which began in 2005 when Lenovo bought IBM's desktop PC business, including the ThinkPad laptops.
Under the terms of the deal Lenovo will fork over $2 billion in cash with the balance in stock. A company spokesman said some 7,500 IBM workers will be offered positions at Lenovo.

(Although Cadalyst c2012 is now available, they opted to eschew c2011 to enable apples-to-apples comparisons with the previous model, and they continue to eschew AutoCAD 2011 while they await NVIDIA’s update of its enhanced driver for AutoCAD 2012.) They set the screen resolution to 1,280 x 1,024 and the color depth to 32-bit, enabled hardware acceleration for AutoCAD, and turned off upright sync for the graphics card.
Once the dust settled and they had a casual to view the results, they were astounded. The Cadalyst c2011 total index score with the NVIDIA NVGL10.hdi driver was 50% faster than any mobile computer previously reviewed by Cadalyst Labs. The total index even beat the fastest desktop workstation they gain ever tested by 25%. The complete set of benchmark scores were: total index of 1,530; 3D graphics index of 5,361; 2D graphics index of 326; disk index of 188; and CPU index of 245.
The weighted scores for the SPECviewperf 11 suite of tests, separate sample mode only, were as follows: 46.05 for catia-03, 41.93 for ensight-04, 54.04 for lightwave-01, 85.33 for maya- 03, 9.61 for proe-05, 50.30 for sw-02, 44.88 for tcvis-02, and 42.97 for snx-01. These scores are too excellent. In fact, three depict Cadalyst Labs top scores by a wide margin compared with the next closest competitor (desktop or laptop): ensight-04 (30% faster), snx-01 (29%), and tcvis-02 (23%).
For the record, the c2011 benchmark scores using the default AutoCAD 2011 driver were: total index of 396, 3D graphics index of 898, 2D graphics index of 251, disk index of 185, and CPU index of 250. The cooling fan of the EliteBook 8760w operated at complete throttle during portions of the testing. The fan kept temperatures down, but the clamor was distracting.
Battery performance. The EliteBook 8760w’s external power brick measures 77/8" x 37/8" x 1". Their review unit included a yardstick 8-cell (83WHr) lithium-ion battery.
We used the Battery Rundown Test option included with the Cadalyst c2012 benchmark to note how the EliteBook 8760w handles life off the power grid. They ran the test four times and organize the battery lasts an tolerable of 100 minutes under maximum operating conditions. The battery lasted an tolerable of 2 hours, 50 minutes in idle mode, with default power settings and no applications running. What about charging the battery? Their testing showed the battery reaches 98% capacity in 100 minutes. These times are only guidelines; performance will subside after repeated battery discharge cycles.
The 17.3" HP EliteBook 8760w has a full-sized, backlit keyboard that includes a dedicated numeric keypad, touchpad, and pointing stick.
Extras. The EliteBook 8760w is not just fast, it is rugged. Its hybrid magnesium-aluminum metal case is designed to provide maximum protection for the internal equipment — it even meets the MIL-STD-810G military standards for environmental conditions, including temperature, altitude, humidity, dust, and vibration. The case measures 16¹/8" x 10½" x 17/8" and weighs 9 lbs — typical for a powerful 17.3" mobile computer.
HP is known for including powerful tools and extra features with its products, and the EliteBook 8760w is no exception. The HP SoftPaq Download Manager provides a separate interface to manage and download software updates for outright system components. The HP Power lieutenant lets you fine-tune power-management settings; using dedicated circuits on the motherboard, it provides real-time data on battery employ and displays current power consumption in watts. You can customize your power employ based on the time of day or day of the week.
The EliteBook 8760w includes a limited three-year onsite warranty; the battery is covered for one year. Extended warranty plans are available. HP offers round-the-clock e-mail and online technical advocate during the life of your warranty.
In closing. The HP EliteBook 8760w is the most powerful mobile workstation to pass through the doors of Cadalyst Labs. Of course, you'll pay a expense for this much power, but it's not as expensive as you might think. As configured for this review, this model costs $5,003. Anyone looking for high-end CAD workstation performance in a mobile figure factor should check out the HP EliteBook 8760w. Highly Recommended.

MariaDB TX, proven in production and driven by the community, is a complete database solution for any and every enterprise — a modern database for modern applications.
As most, current database systems soundless simply store current condition or past states within one tall relational table. They investigated what the performance drivers are and how to better on the current state-of-the-art. They implemented an open-source storage system called Sirix(.io) from scratch, which stores miniature sized snapshots as well as supports sophisticated time-travel queries while competing with the efficiency of non-temporal database systems.
What Is a Temporal Database System?
It is a term used to report that a system is capable of retrieving past states of your data. Typically, a temporal database stores both convincing time, how long a fact is factual in the existent world, as well as transaction time when the data actually is committed to the database.
Questions such as, "Give me eventual month’s history of the Dollar-Pound Euro exchange rate. What was the customer's address on July 12th in 2015 as it was recorded in the day? Did they trudge or did they rectify an error? Did they gain errors in the database, which were corrected later on?"
Let’s circle their focus to the question of why historical data hasn’t been retained in the past and how fresh storage advances in recent years made it feasible to build sophisticated solutions to benefit reply these questions without the hurdle state-of-the-art systems bring.
Advantages and Disadvantages of glance Drives as for instance SSDs
As Marc Kramis points out in his paper “Growing Persistent Trees into the 21st Century”:
The switch to glance drives keenly motivates to shift from the “current state’’ paradigm towards remembering the evolutionary steps leading to this state.
The main insight is that glance drives as for instance SSDs, which are common nowadays gain zero hunt time while not being able to achieve in-place modifications of the data. glance drives are organized into pages and blocks, whereas blocks Due to their characteristics they are able to read data on a fine-granular page-level, but can only efface data at the coarser block-level. Blocks first gain to be erased, before they can be updated. Thus, updated data first is written to another place. A garbage collector marks the data, which has been rewritten to the fresh district as erased, such that fresh data can be stored in the future. Furthermore, index-structures are updated to locate the data in the fresh place.
Evolution of condition through fine-grained modifications
Furthermore, Marc points out that miniature modifications, because of clustering requirements due to leisurely random reads of traditionally mechanical disk head hunt times, usually involve writing not only the modified data but too outright other records in the modified page as well as a number of pages with unmodified data. This clearly is an undesired effect.
How They Built an Open Source Storage System Based on These Observations From Scratch
Sirix stores per revision and per page-deltas.
Due to zero hunt time of glance drives, they achieve not gain to cluster data. Sirix only ever clusters data during transaction commits. It is based on append-only storage. Data is never modified in-place.
Instead, it is copied and appended to a file in a post-order traversal of the internal tree-structure in batches once a transaction commits.
We borrowed ideas from the filesystem ZFS as for instance checksums stored in parent database-pages/page-fragments, which forms a self-validating merkle-tree as well as their internal tree-structure of databases-pages.
In stark contrast to other copy-on-write (COW) approaches, however, they achieve not simply copy the gross record-page, which is a blow of storage space. Depending on the used versioning algorithm, they only copy a number of records from the page (everytime the changed records itself).
Versioning Algorithms for Storing and Retrieving Record-Level Snapshots
For most database systems, they store a fixed number of records, which is the actual data per database-page (currently 512 records at most). The records themselves are of variable sizes. Overlong records, which exceed a predefined length in bytes, are stored in additional overflow pages and only referenced in the record pages.
We implemented a number of versioning strategies best known from backup systems for copy-on-write operations of record pages. Namely, they either copy:
the complete record-pages, which is any record in the page (full)
only the changed records in a record page regarding the former version (incremental)
only the changed records in a record page since a full-page dump (differential)
It is well known that each of these versioning strategies has its advantages and drawbacks. Simply storing the gross page (full) is very efficient for reading operations. However, write performance in comparison to outright other approaches is the worst, as they simply copy outright unchanged records in addition to outright changed records.
Incremental versioning is the other extreme and write-performance is best, as it stores the optimum (only changed records), but on the other hand, reconstructing a page needs intermittent complete snapshots of pages such that the performance doesn’t deteriorate with each fresh revision of the page as the number of increments increases with each fresh version.
Differential versioning tries to balance reads and writes a bit better but is soundless not optimal. Each time records in a page are modified, a fresh page is written with outright changed records since a past complete dump of the page. This means that only every two revisions of the page-fragment gain to be read to reconstruct a record-page. However, write-performance too deteriorates with each fresh revision of the page.
Incremental versioning in regards to write performance, due to the requirement of intermittent complete dumps of the page, results in write-peaks. Differential versioning too suffers from a similar problem. Without an intermittent complete dump, a lot of data would gain to be duplicated on each fresh write.
Marc Kramis came up with the belief of a novel sliding snapshot algorithm, which balances read/write-performance to circumvent any write-peaks.
The algorithm makes employ of sliding windows. First, any changed record must be stored. Second, any record that is older than a predefined length N of the window and that has not been changed during these N-revisions. Only these N-revisions at max gain to be read. The fetching of the page-fragments could be done in parallel or they simply cease once the full-page has been reconstructed starting with the most recent revision.
Once they made sure their storage system scaled linearly for fetching old-revisions as well as the most recent revision and logarithmic for fetching and storing separate records as well as gross revisions they focused their attention to upper layers.
DOM Alike API
We then invested a lot of toil to implement a persistent DOM-interface (for instance to store XML-documents and in the future JSON-documents natively).
Our records are stored with stable identifiers, which never change, regardless of the fact if the records are updated or not and where they physically reside. Markers are inserted for deleted records. The encoding is simply first-child-, left-sibling-, right-sibling-, parent- and node-ID in order to store a benevolent of DOM representation of currently XML/XDM-nodes.
Versioned, Typed, User-Defined Indexes
We then shifted their focus again to implement versioned user-defined, index-structures.
During each transaction confide a snapshot not only of the stored data but too of the indexes is generated. The indexes currently are based on AVL-trees/AVL-nodes stored in record-pages in different subtrees of their internal ZFS alike tree-structure.
A path summary of outright paths in the resource is kept up-to-date at outright times.
To enable users to Make the most of their temporal database system and to actually easily reply the aforementioned questions one would likely be able to collect answered by a temporal database system they extended a query-compiler called Brackit.
Users are now able to open specific revisions, navigate in the DOM-alike tree-structure to select nodes in a specific revision and then navigate in time. Through novel time-based axis it is for instance easily feasible to analyse how the selected or a sequence of records/the nodes looks fondness in the next revision, the previous revision, the first or the eventual revision, the past- or future-revisions, all-revisions…
Furthermore they are able to query a compass of revisions either based on given timestamps or the IDs of the revisions.
But what if they want to import several revisions of preexisting documents or compare any revision stored in their system independent of the versioning algorithm they chose?
We first implemented a diff-algorithm called fast-matching-simple-edit script (FMSE) to advocate the import of different versions of a document and confide several revision in their storage system. The algorithm does not depend on node-identifiers. It matches based on similarities of subtrees through first calculating a Longest Common Subsequence (LCF) on the leaf nodes of the tree-structured document to import (currently XML, in the future too JSON). Then it tries to match artery bottom up. In the next step, edit-operations are applied to transform the document from one version to another version. The algorithm obviously uses heuristics at a figure of the tree-to-tree correction problem and thus NP-hard. It works best and produces a minimal edit-script if the leaf nodes are very distinctive.
ID-based algorithm optionally making employ of stored hashes
In order to compute diffs between any revision of Sirix-resources and regardless of the record-page plane versioning, they developed an algorithm, which makes employ of their stable record-identifiers (which is a based on a sequence generator and never reassigns IDs (from deleted records for instance). If they store hashes of the nodes during insertion, the diff algorithm is able to skip whole-subtrees if the node-identifiers as well as the hashes match.
Depicts how the ID-based diff algorithm works
Non-Blocking, Asynchronous RESTful API
We recently built on top of their XQuery and DOM-API layers a higher plane API to communicate with a Sirix server based on Vert.x, Kotlin/Coroutines, and Keycloak for authentication. The implementation and usage examples thereof already were the theme of another article.
A Visual Analytics Approach for Comparing Tree-Structures
As shown in a few screenshots, they once developed a Visual Analytics approach to compare tree-structures stored in Sirix. However, it’s a bit dated and needs to be ported to the web.
What They Are Working On
Next, we’ll investigate how to best store JSON-documents, which simply boils down to the question of how fine-granular they want their records to be (for instance demur record nodes, array-index nodes…)
However, they would be more than cheerful to contend future directions and ideas. Any benefit is greatly appreciated.
