The present invention relates to providing robust and cost-effective field replaceable information processing modules for such a system.
An aspect of the invention can provide a blade configured to be receivable as a field replaceable unit in a carrier of a blade server system, the blade comprising a blade enclosure having a first metal portion and a second plastics portion.
In the context of this document, a blade is to be understood to be a component of a blade system, for example a blade server system, that is mountable in a blade carrier of the blade system, for example a rack mountable shelf. The blade could, for example, form a server or a special purpose module forming part of a server system. By arranging that the blades have a small frontal area, for example by being narrow, or shallow, a high density of blades can be received in the carrier.
The provision of a blade enclosure for the blade means that a blade for use in a blade system can be made robust and resistant to damage. The enclosure can protect the components of the blade from physical damage and can also isolate them from electrical, static and other effects that could be potentially damaging to the bade components. Indeed, by providing a blade with an enclosure, it is no longer essential for an operator to employ skilled technical staff to replace a faulty blade, as the blade components are protected by the enclosure.
As a result, such a blade could be described as a customer replaceable unit (CRU) as opposed to merely a field replaceable unit (FRU). The use of an enclosure that is formed partly from metal and partly from plastics material means that a light and yet robust enclosure can be made. The use of metal can provide strength and electromagnetic interference shielding with a very thin layer. The use of plastics can provide lightness, flexibility in design, and the avoidance of metal to metal contact to facilitate insertion and removal of the blades.
The metal portion can form one face (e.g., a side face), and the plastics portion can form an opposite side face. As a result, metal to metal contact between adjacent blades can be avoided.
The plastics portion can also form a bezel forming at least one end face of the enclosure. The bezel can carry blade status indicators. The bezel can also include a pivotal mounting for an ejector lever mechanism for the blade. The bezel can further include a detent retaining a latch of the lever mechanism.
As the blade can have a very narrow form factor, if there is insufficient width for components of the blade, the plastics portion can include an aperture in the side wall to accommodate those components. The aperture can be closed by a metal layer.
In order to provide electromagnetic interference shielding, the plastics portion can be provided with at least a conductive layer, for example by means of a thin inner metallic layer, or sheet, that can, for example, be heat bonded to the plastics layer. The plastics portion can include apertures for electromagnetic interference fingers so that the fingers can contact the thin metal layer through the plastics portion.
The blade can be configured to be slideably insertable into the carrier and the upper and lower surfaces can be provided with guide formations for engaging with corresponding guide formations of a blade receiving location in the carrier. The guide formations of the plastics portion can include at least one groove. A groove in one of the upper and lower faces can be wider than a groove in the other of the upper and lower faces. A groove can be formed with a wider entry portion to facilitate alignment of the blade. Providing the grooves in a plastics portion allows great flexibility as the form and configuration of the grooves. Also, where the corresponding guide formations comprise metal, this can avoid metal to metal contact, and can thereby facilitate the sliding in and out of the blades.
Another aspect of the invention provides a carrier for a blade server system comprising a carrier enclosure that includes at least one blade receiving location configured removably to receive a field replaceable and enclosed blade. The blade receiving location can be formed with guide formations for engaging with corresponding guide formations of a received blade.
A further aspect of the invention provides a rack mountable shelf as a form of carrier. Another aspect of the invention provides a computer server system including one such rack mountable shelf. A further aspect of the invention provides a rack mounted computer server system comprising a rack frame and, mounted in the rack frame, at least one such rack mountable shelf. A high density computer system can be provided that includes at least one rack frame with, mounted in each rack frame, at least one such rack mountable shelf.
Another aspect of the invention provides method of providing high density computer services. The method includes: providing a rack mountable shelf providing a plurality of receiving locations, each for receiving a plurality of field replaceable units in the form of enclosed blades; providing guides cooperating with guide formations on the blades and in the receiving locations, wherein at least one of the guide formations on the blades and in the receiving locations comprises a plastics bearing surface.
FIGS. 19 to 23 are is a schematic diagrams showing parts of an information processing cartridge enclosure and an ejection lever for the cartridge.
At least one fan can be located, for example behind the perforated portion 135 of the rear face, in a CSSP cartridge 71 to channel cooling air through the CSSP cartridge 71 from the front to the rear. In this particular example shown, two fans are provided, one behind each set of perforations 135. LED indicators 137, as shown in FIG. 4, can be provided on the rear face 122 of the CSSP enclosure 121 to indicate whether power is on, whether service intervention is required and whether the switch can be removed. Additional link status indicators can be provided integral to 2×4 stacked RJ45 connectors 139, also shown in FIG. 4. As shown in FIG. 4, electrical connections 141 can be provided at the front face of the CSSP (i.e. on the face that in use is inside the shelf enclosure 47). Suitable connections for use in the present example include a connector for power connections, a connector for serial management data connections and a connector for information connections. In the present example, information connections are implemented using an Ethernet information communication protocol, e.g. at 1 Gigabit (Gb). However other protocols could equally be used, for example the Infiniband information communication protocol. The connector arrangement can include a guide pin arrangement to prevent module misalignment during insertion of the CSSP module into the receiving location. For this purpose, guide pin holes 142 can be provided on the front face 123 into which guide pins may pass to aid module alignment.
With reference to FIGS. 12 a and 12 b, there now follows a description of an example of a combined switch and service proccssor (CSSP) 71. In the present exampic, each CSSP 71 provides the functionality of a Switch 73 and of a Shelf Service Processor, or Shelf Service Processor (SSP) 74.
FIGS. 12 a and 12 b provide an overview of the functional components of the CSSP 71 including functional components of the Switch 73 and functional components of the SSP 74. In the present example, most of the components relating to the Switch 73 are mounted on a Switch PCB 231, and the components relating to the SSP 75 are provided on a SSP PCB 232. However, it should be noted that the components located in the lower portion of the switch PCB 321 (i.e., that portion below the SSP PCB 232 as illustrated in FIGS. 12 a and 12 b logically belong to the SSP 74, rather than to the switch 73. It will be appreciated that such component arrangements arc not compulsory for successful operation and that any other component arrangement over any number of component boards can be easily achieved using conventional component arrangement techniques.
Firstly, with reference to FIGS. 12i a and 12 b, there follows a description of functional elements of the Switch portions 73 of a CSSP 71 as contained within the CSSP enclosure 121.
When the CSSP 71 is inserted the inrush current can be limited, for example to <1 A, and the rate of rise can be configured not to exceed a predetermined value (e.g., 20 A/s) to provide a so-called soft start to facilitate hot-insertion. The intent is to prevent damage to the connectors and to avoid generating noise. A soft start controller 283, which controls a ramping-up of voltage levels, can be enabled when the predetermined signal (Inserted_L signal) is asserted low, this signal is on a short pin in the connector and is connected to ground (GND—not shown) through the midplane 171 until one of the supplies is removed. These circuits can be configured to withstand an overvoltage at their inputs whilst the input they are feeding is not powered, without any leakage to the unpowered circuit. A sense circuit can detect if the voltage has dropped below a threshold, for example 2.0V, as a result of a blown fuse, a power rail going down, etc. The DC/DC converters 281 can be protected against short circuit of their outputs so that no damage occurs.
LED indicators 137 can be provided, for example with a green power LED, an amber LED for indicating that service is required and a blue LED for indicating that the switch is ready to be removed. LED indicators integrated on 2×4 stacked RJ45 connectors on the rear face of the CSSP 71 can be arranged, for example, to show green continually when the link is present and flash green when the link is active.
For external IO, rear panel Gb Ethernet connections can be provided from the two quad PHYs 253, 254 to 2×4 stacked RJ45 connectors 139 (to give 8 uplinks). Each port can be an independent 10/100/1000 BASE-T (auto negotiating) port. The PHY devices 253, 254 can operate in GMII mode to receive signals from the 8-Gigabit interfaces on the ASICs 244, 245.
There is no limit placed on the processing cartridges as to what software they should run. Each module within a shelf or farm may run under the same operating system, or a plurality of different operating systems may be used. Examples of possible operating systems include Sun Microsystems' Solaris® OS or another UNIX™-Type OS such as Linux™, MINIX™, or Irix™, or UNIX™ or a Microsoft OS such as Windows NT™, Windows 2000™Windows ME/98/95™, Windows XP™.
As has been described above with particular reference to FIG. 5B, each information processing cartridge 43 may be provided with an injection/ejection lever 111. An arrangement of such a lever can provide a mechanical retention mechanism for retaining an information processing cartridge 43 within a shelf 41, a handle by means of which a user may pull an information processing cartridge 43 from a shelf 41, and provide for the flow of cooling air into a processing cartridge 43 via apertures in the front face 102 thereof. The injector lever interfaces with the bezel of the information processing cartridge enclosure 101.
There will now be described an example of an injection/ejection lever arrangement for an information processing cartridge 43. Particular reference will be made to FIGS. 19, 20, 21, 22 and 23.
Shown in FIG. 19, is a side view of a front end of an information processing cartridge enclosure 101. Attached to the front face 102 of the enclosure 101 is a handle 111. In the present example, the handle 111 comprises an outer member 500 and in inner member 501. The outer member forms the front and side faces of the handle 111. This can advantageously be formed from a strong structural material such as a metal. However, other materials could be used, for example structural plastics. Where the outer member is formed of a structural material, the inner member does not need to be formed of a structural material. It could, for example, be formed from a relatively thin plastics moulding for lightness and ease of forming. The inner member forms the rear face (the face closest the front face 102 of the enclosure 101) of the handle 111. The handle 111 is, in the present example, hollow.
The outer member 500 comprises a number of retaining ejector/injector protrusions 503. In the present example, two protrusions 503 are provided extending from each side face of the handle 111 at the top of the handle 111. The protrusions 503 are configured to interface with one or more apertures within the shelf 41 to cause the information processing cartridge 43 to become secured in place within the shelf 41. To provide for the protrusions 503 to move from a closed or injected position (as shown in FIG. 19) where the protrusions cause the information processing cartridge 43 to be retained in place in the shelf 41 to an open or ejected position (as shown in FIG. 21), the handle 111 is, in the present example, configured to hinge away from the front face 102 of the enclosure 101.
The front face 102 of the enclosure 101 has a hinge mounting part 531 thereon, to which the handle 111 may be hingeably attached. The hinge axis of the handle 111 is arranged to be substantially parallel to the plane of the front face 102 of the enclosure 101 and to be substantially perpendicular to the length of the enclosure 101. In the present example, the handle 111 is hinged to the hinge mounting part 531 by a bar 507. To cause the handle 111 to remain in the closed (injected) position when the information processing cartridge 43 is located in a shelf 41 and is to be retained therein by means of the handle 111, a closure latch mechanism is provided at the end of the handle 111 remote from the hinge axis. The closure latch mechanism will be described in more detail with reference to FIGS. 21, 22 and 23 below.
FIG. 20 shows a front view of the handle 111 in the closed position. From this Figure, it can be seen that the present example of the handle 111 is formed in the shape of an elongate X. This shape can provide a handle extending substantially the full height of the front face 102 of the enclosure 101 which allows a flow of air to pass around the handle such that the air may flow into the enclosure 101 through the apertures 115. Located between the arms, or limbs, of the handle at the top thereof is a panel attached to the hinge mounting part 531, which panel comprises the blade status indicator LEDs 119. Located between the arms, or limbs, of the handle at the bottom thereof is a member 510 which forms a part of the closure latch mechanism. The outer surface 511 of the member 510 may in selected embodiments be provided with an indication of information relating to the particular information processing cartridge 43 to which it is attached. In the present example, the surface 511 may be color-coded to indicate a configuration of the information processing cartridge 43, particularly a hardware configuration.
Referring now to FIG. 21, the handle 111 is shown in the open position. As can be seen therefrom, the protrusions 503 are moved to positions wherein the extension of the protrusions 503 beyond the top face of the enclosure 101 is reduced relative to the positions of the protrusions at the closed (latching) position. Also shown in FIG. 21 is part of the closure latch mechanism. A latch protrusion 521 extends from the rear of the handle 111 toward the end of the handle remote from the hinge axis. The latch protrusion 521 is configured to interface with a latch receptacle 541 of the front face 102 of the enclosure 101 when the handle is in the closed position to maintain the handle in the closed position. The handle may be biased toward the open position by means of a biasing element or elements, for example a pair of springs 537 arranged to act, one on each side of the handle, between the hinge mounting part 531 and the hinged end of the handle 111.
FIG. 22 shows an exploded view of parts of the handle 111. At FIG. 22(a) the parts of the closure latch mechanism associated with the handle 111 are shown and at FIG. 22(c) the parts of the closure latch mechanism associated with the enclosure 101 are shown. The closure latch mechanism comprises a movable member 510 which, when assembled into the handle 111 is rotatably mounted between the lower arms of the handle 111 (see FIG. 20). The moveable member 510 pivots to the handle 111 about a pivot axis 525. The movable member 510 comprises the latch protrusion 521 and a biasing tongue 523. In use, the biasing tongue 523 acts against the inside rear surface of the handle 111 to cause the latch protrusion to be biased toward a position at which it will be retained by the latch receptacle 541 of the front face 102 of the enclosure 101. The protruding end 522 of the latch protrusion 521 and the outer face 542 of the latch receptacle 541 are configured to cause the latch protrusion 521 to be rotated against the biasing effect of the biasing tongue 523 upon pressing of the handle toward the closed position. The latch protrusion 521 may thus pass around the outer face 542 of the latch receptacle 541 following which the biasing effect of the biasing tongue 523 causes the latch protrusion 521 to move to a position extending behind the latch receptacle 541. The closure latch mechanism is thus closed and the handle may be maintained in the closed position thereby.
In the example shown it will be appreciated that the biasing force exerted by the latch protrusion 521 on the closure latch member 510 is a rotational direction (anti-clockwise as shown in FIGS. 21 and 23) opposite to the biasing force (clockwise as shown in FIGS. 21 and 13) exerted by the springs 537 on the handle 111.
In order to open the closure latch mechanism such that the handle 111 may be moved from the closed position to the open position, an aperture 527 is provided in the movable member 510 at a position on the bottom end of the handle 111. The aperture can conveniently be sized such that the operator may release the closure latch mechanism by using a finger to apply a force on the aperture 527 in a direction away from the front face 102 of the enclosure. When such a force is applied, the movable member 510 is caused to rotate about the pivot axis 525 against the biasing effect of the biasing tongue. This rotation causes the latch protrusion 521 to disengage from the latch receptacle 541 such that the handle may be moved to the open position, with the help of any biasing spring 537 provided.
As shown in FIG. 22(c) the hinge mounting part 531 has an axle aperture 533 extending therethrough from one side thereof to the other. The axle aperture 533 is configured to have a bar inserted therethrough and through corresponding apertures 509 of the handle 111 to provide a hinged attachment of the handle 111 to the housing 101. The bar may be secured in the apertures 509 and 533 by any suitable means which allows the relative rotation of the handle 111 against the hinge mounting part 531.
As discussed above, biasing springs 537 may be provided to cause the handle to be biased toward the open position. Such springs may be provided in spring receiving recesses 535 to act between the front face 102 and an inside surface of the handle 111.
Referring now to the cutaway diagram of FIG. 23, the relationships of the separate parts of the handle when assembled may be seen. The biasing spring 537 is shown at a position corresponding to the spring receiving recesses 535 of the hinge mounting part 531. Also, the latch protrusion 521 is shown engaged with the latch receptacle 541, held in position by the biasing effect of the biasing tongue 523 acting on the inside rear surface of the handle 111.
The protrusions 503 can be arranged both to act as injector and ejector protrusions subject to the configuration of the formations on the carrier with which they are to engage. Alternatively, one of the protrusions on each side can act as an injector protrusion and one as an ejector protrusion on alternate edges of an aperture provided in a front face of the chassis 47 of the carrier. In the drawings, a slot 68 forming an opening to the plenum chamber 66 is shown. As described, the slot 68 could also be formed as a series of apertures. This slot, or those apertures 68 can serve as the formation with which the protrusions 503 engage. The slot 68 is shown in FIGS. 8A and 8B in a substantially vertical front face for ease of illustration. However, the engagement of the protrusions with the apertures/slot 68 is facilitated by forming the apertures/slot 68 in a portion of the front face 51 of the chassis 47 that is angled forwards so that a normal to the plane of the apertures/slot is angled downwards.
There has been described a blade (e.g., a blade server) configured to be receivable as a field replaceable unit in a carrier of a blade server system, the blade comprising a blade enclosure having a first metal portion and a second plastics portion. The use of an enclosure that is partly formed of metal and partly formed of plastics material is used to good advantage in an embodiment of the invention.
In the described example where a blade enclosure has six faces, a metal portion can form at least a first face (e.g., a side) of the enclosure and at least part of at least one of four adjacent faces (upper, lower and end faces), and a plastics portion can form at least a second face (e.g., an opposite side face) and at least part of at least one of the four adjacent faces of the enclosure (upper, lower and end faces).
The plastics portion further includes a bezel forming at least one end face of the enclosure. The bezel can include various features including ventilation slits, blade status indicators, a pivotal mounting for an ejector lever mechanism for the blade and a detent for retaining a latch of the lever mechanism. The use of plastics for the bezel gives design freedom.
To provide electromagnetic inference shielding, the plastics portion can be provided with at least a conductive layer, for example a thin inner metallic layer heat bonded to the plastics layer. The plastics portion can include apertures to permit electromagnetic interference fingers to contact the thin metal layer through the plastics portion.
The blade can be slideably mountable in the carrier with connectors being located on face of the blade enclosure that is inserted first into the carrier. The metal portion can be formed from a stamped steel sheet. The plastics portion can be formed from a plastics moulding, for example from PC-ABS.
The plastics portion can form at least part of the upper and lower surface of the enclosure. This is advantageous in that, where the blade is slideably insertable into the carrier, the upper and lower surfaces can be provided with guide formations for engaging with corresponding guide formations of a blade receiving location in the carrier. These guide formations can be formed in the plastics portion giving design freedom and avoiding metal to metal contact, especially where the corresponding guide formation are metallic. The guide formations in the plastics portion can be in the form of a grooves, possibly with a groove in one of the upper and lower faces that is wider than a groove in the other of the upper and lower faces to accommodate different corresponding guide formations. The wider entry to the grooves can readily be formed in the plastics portion.
A carrier for a blade server system can include a carrier enclosure that includes at least one blade receiving location configured removably to receive a field replaceable and enclosed blade, the blade receiving location being formed with guide formations for engaging with corresponding guide formations of a received blade. At least one blade receiving location guide formation can be formed by a folded portion of a wall of the carrier, for example to form a rail that includes first and second stamped upstands from material (e.g., sheet metal such as steel) forming a base of the carrier. At least one blade receiving location guide formation could be in the form of a sprung wire loop that projects from a wall of the carrier.
