Exadata V2 after exadata V1 is the one of the first integrated Solution of Oracle and Sun.
For some reason oracle keep the specific components of V2 in top secret.
Beside some datasheet and some whitepaper the product documents are not available to general public
these are contrast that oracle provide all tech docs for database and apps available and public can down the software to try things out.
It is interest that the HW and SW price of exadata and all DB SW products and support price are in public view but not the HW support
Using only the public information we know that exadata system consist of
- database Machines, x4170, 1U, IB HBA, HW-RAID HBA with 512MB NVRAM
- exadata storage cells, x4275 , 2U and smart Flash and IB HBA and HW-RAID HBA with 512MB NVRAM, 600GB SAS or 2TB SATA HDD.
- ethernet switch 1U , cisico brand model not specified (in FAQ) that connect eth0 and ILOM
- LCD tray , mouse and keyboard, 1U, model not specified
- KVM switch, 1U,model not specified
- IB switches, Sun 36 port 1U switch
- Sun Rack II and PDU
Only in the tech presentation that it mention that smart flash come from
4x 96 GB Sun Flash PCIe Cards (384 GB total) note that this PCIe Cards is not supported in the standalone X4275. The PCIe Cards was not mention in the datasheet.
512MB HW-Raid HBA U cannot find it in the x4275 HBA list , the newer westmere based system x4270 M2 will support 512MB HW-RAID HBA and Sun Flash PCIe Cards outside of the exdata system.
Full rack consistent of 8 X4175(1U),14 X4275(2U), 3 IB switch(1U), 1 ethernet switch(1U), one KVM(1U) and one LCD tray(1U), total of 42U.
Anyone know anything about HW will thinking about there are a lot cables in full rack.
Each machines will have 2 IB cables, two Cat5 for ethe0 and ILOM, one cable for KVM, we have over 110 cables.
Since Oracle does not show any picture on the rear of full rack we donot know this many cables’ impact of the air flow path of the cooling cool air.
How can one improve the cable situation?
- Oracle/Sun Nehalem and westmere servers all support side-band management, that is ILOM and eth0 can share one cat 5 cable but provide two IP/MAC address, so one can reduce one cat5 cable per server
- KVM switch is so Window like, very few Sun HW user use KVM, one can do without KVM, one fewer cable per server We are down to about 66 cables instead of 110 cables
- In place of 1U KVM one can put x4170 server as management node that will store kickstart image of the DB machine and Exadata storage machine and it could also serve as oracle Enterprise Management server node.
- AFAIK, OEM doesnot yet support ILOM firmware update capability, putting OEM ops center just for ILOM firmware upgrade will be overkill. May be one can provide some “expect” scripts for this purpose
Oracle did not provide any product docs for exadata V1 and exadata V2 and keep some components under wrap may be just to keep the competitor in the dark but in the process also keep the potential customer in the dark.
Of course once U sign the BIG contract U will have access all the documents.
IMHO, any customer that are thinking about this groud breaking Exadata solution would want to understand:
- What kind of training customer need so customer can manage exadata system in day to day operation for DBA, operator and SA?
- How exadata fit into the customer existing monitoring env?
- How exadata fit into customer existing backup and DR env?
- How customer manage the patching and firmware update for all HW, SW?
- How customer manage the replacement of bad components?
Yes oracle ACS will help customer arch and migrate from old to new env and if for any customer ACS will need to do one of kind solution for every customer, we know this is not sustainable.
Who know, LJE’s comment that he want Oracle to be like IBM may have multiple meaning!
