For Current/Maximum Capacity Descriptor of the READ FORMAT CAPACITIES command there are two implementations on BD-R drive with a Blank BD-R disc. The 1st implementation reports Data Area size as Spare Area included that is specified by BD-R specification. The reported value includes Inner Spare Area that host never be able to Read/Write. The 2nd implementation reports User Data Area size that does not include the Inner Spare Area. MMC5-BSR+INCITES=430.pdf on page 471 Table 468 ? Current/Maximum Capacity Descriptor for Unformatted or Blank Media BD-R: The number of sectors in all the data zones on the media. MMC5 used a term "data zone" for two meanings. The 1st meaning is Data Zone of BD-RE/R that includes user data recordable area and spare area. The 2nd meaning is user data recordable area. These two usages allow these different implementations of BD-R drives. On the other hand MMC3/MMC4 specifies generic definition of Current/Maximum Capacity Descriptor of the READ FORMAT CAPACITIES command as follows; mmc3r10g.pdf Table 210 on page 201 01b Unformatted Media. The reported value is for the maximum formatted capacity for this media. For DDCD/CD-RW medium, the value reported is the maximum possible when using Format Type 10h. mmc4r05a.pdf Table 416 on page 347 01b Unformatted Media. The reported value is for the maximum formatted capacity for this media. These two descriptions said that the original intention of this field requests to show the possible maximum recordable / readable capacity of a disc. Fortunately Data Zone of CD/DVD does not include Spare Area. Then capacity of all Data Zones of CD/DVD disc follows the original intention. BDA concluded that two different implementations do not cause any trouble and both implementations are reasonable. Therefore BDA would like to request to MMC WG that MMC6 may have a note that explains these two implementations of the BD-R writable drives as follows. Note: There are two implementations for BD-R writable drive. One implementation reports a value that includes Inner Spare Area. Another implementation reports a value of the maximum user data recordable area. Host may use the third descriptor values of Format Type 32h or READ TRACK INFORMATION Command response to obtain a maximum recordable capacity of the Blank BD-R disc. I personally think that MMC6 may have same table with Table 210 of MMC3 to explain this original intention and then explain each medium definitions.

Page 444, Table 359, SPC-4 r17. This table defines the Protocol Specific Logical Unit mode page. Offset 2, bits 7-4 are reserved. Offset 3+ are the protocol specific mode parameters. Page 561, Table 221, SAS-2 r15 (same applies to SAS-1). This table details the SAS version of this mode page. Note, however, that SAS defines bit 4 offset 2 as the "Transport Layer Retries" bit. Reserved is well defined as: 3.3.8 reserved: A keyword referring to bits, bytes, words, fields and code values that are set aside for future standardization. A reserved bit, byte, word or field shall be set to zero, or in accordance with a future extension to this standard. Recipients are not required to check reserved bits, bytes, words or fields for zero values. Receipt of reserved code values in defined fields shall be reported as an error. The SAS specification conflicts with the SPC specification in this regard. I believe SPC-4 should be amended to clarify this conflict. Perhaps define that one bit, or all four bits, as protocol specific as opposed to reserved.

Note that these directions are NOT included in meeting announcement at www.t10.org. HOWEVER for some reason, just this week Google maps has taken to setting a route from Orlando International Airport to the hotel that involves taking surface roads to join up with I-4, and is complex to follow around the airport. While that route will work, and may avoid all tolls, I'd still personally recommend using the Greeneway as follows: a) Head towards the North exit from Orlando International Airport, and then take the first ramp on the right which signposted to SR-528-TOLL East towards COCOA/ KENNEDY SPACE CENTER; b) After 3.9 miles, take EXIT 16 towards SR-417/ TAMPA/ ORLANDO; c) After 0.3 miles, take the SR-417-TOLL North exit on the LEFT toward ORLANDO/ SANFORD (see below for info on the tolls on SR-417); d) After about 28 miles, take the RINEHART ROAD exit, EXIT 54; e) At the end of the ramp, turn LEFT onto RINEHART RD; f) After about 1.5 miles turn RIGHT onto HE THOMAS JR PKWY, and cross over I-4; g) After about 0.7 miles, turn LEFT onto INTERNATIONAL PKWY, and then take the second left turn into the Marriott. This route from Orlando Airport avoids downtown Orlando and the busy stretch of I-4, but involves paying three tolls - two of 50c each and one of $2. There are exact change lanes at the first two toll booths, so bring some quarters, or see item #2 below. Also, if you're following other directions from Orlando Airport that go via SR-408 and I-4, there's a 75c toll on that route too! Note that the last step of each of the sets of directions from Google Maps is incorrect - it is no longer necessary to make a U-turn on International Parkway at Heathrow Park Lane - you can instead take the 2nd left on International Parkway directly into the hotel complex. 2) PLATEPASS If you're planning to rent a car from Avis, Budget, or Hertz, check if you can take advantage of a scheme called PlatePass that lets rental cars use the automated EPass or SunPass lanes (including the full speed ones) on Florida tollways without needing a radio tag. See http://www.platepass.com for more information. The cost of this scheme is $2.50 for each day you use it, plus the normal tolls. It's charged back to your car rental company, who typically make a separate charge on your credit card. You can get receipts for the PlatePass charges from the website listed above, although when I used the scheme in 2007 took 2 weeks for the receipt to be listed. It's important to make sure you're covered by this scheme in advance because otherwise using those same lanes without a radio tag is a violation that normally results in a minimum $150 fine per instance. If you're planning to drive from the Orlando airport to the hotel in rush hour, PlatePass will likely save you 10 minutes on the trip. 3) TRAFFIC INFORMATION There's a good real time travel & traffic reporting system available by calling 511 on your mobile phone, or at: http://www.fl511.com Select Orlando as the Preset Region, and select the Congestion Layer. 4) MAP If you'd like a good single sheet map of the major roads in Central Florida (including toll booths), please see: https://epass.oocea.com/Corporate/travel/assets/expressway_map_med_res_v 2.jpg On this map the hotel is located near the top center of the map close to CR 46A just west of the junction with I-4. 5) WEATHER The forecast for next week calls for mostly sunny days with highs around 70, and overnight lows in the high 40s. The probability of precipitation is 30% for Sunday, and 10% or less for the other days. 6) HOTEL ROOMS & MULTIMEDIA The hotel has been undergoing an upgrade recently, and I'm told that now MOST of the sleeping rooms now conform to the "next generation room" displayed at http://www.experiencemarriott.com/ - see specifically the "plug in" section. So if you'd like to attach your laptop or DVD player to the panel for the LCD TV, my strong advice is to bring the correct cables with you from home. 7) FOOD I'm sorry, there will NOT be a reception this week - in the current economic situation it couldn't be justified. However, I've a guide to the restaurants in the area around the hotel as 09-037r0. See http://www.t10.org/cgi-bin/ac.pl?t=d&f=09-037r0.htm for the interactive version. One final point: If anyone who has made a reservation at the hotel has to cancel, could they please let me know by replying to this message? This is just so that my numbers for the catering are accurate. I look forward to seeing everyone next week.

Host may use the third descriptor values of Format Type 32h to obtain a maximum recordable capacity of the Blank BD-R disc. MMC5 defines a Blank BD-R disc as follows; The default mode for a blank BD-R disc is SRM with no spares allocated. Therefore READ TRACK INFORMATION Command will report Data Zone that includes Inner Spare Area. When FORMAT UNIT Command is not used the Inner Spare Area size is set to 0 (not allocated) and the user data recordable area of BD-R disc is same with Data Zone size. I'm sorry that I forgot this.

No... the identification sequence does not occur once the OOB sequence has determined that the link is a SATA link. Since these are then SATA links, there are no SL_IR or SL_CC state machines either. So conceptually, as soon as the links exchange the COMWAKEs in your example, they only contain the functionality as defined by the SATA specifications. The STP protocol occurs when you have SATA devices connected to SAS exapanders. The links connected to the SATA devices only run SATA protocol. The links connected to other SAS expanders or SAS end devices (i.e. initiators) are SAS links, that may then establish STP connections. Note that sections M.14 and M.15 of the SAS spec annex show examples of how these SAS and SATA links work within the scope of the expander. Hope this helps!

This does bring up the point that maybe the Power Condition feature (or some subset thereof) should be added to MMC-6 if there is a demand for this feature. I would be willing to work with Bill McFerrin or any other regular MMC group member if the MMC group wants this.

This value is expressed in increments of 512 bytes (i.e., a value of one means 512 bytes, two means 1 024 bytes, etc.). The relationship, if any, between data transfer operations and interconnect tenancies is defined in the individual SCSI transport protocol standards. A value of zero specifies there is no limit on the amount of data transferred per data transfer operation. This works for devices that formatted for data in multiples of 512 bytes per block; however, this does not map well for devices that formatted for Protection information and the block size is 520 bytes. I understand that the data transfer length can be easily compared to number of 512 byte blocks; however, if you want to have a max burst size of 32 blocks that are 520 bytes each then this field does not easily map to the number that you want because 33 would map to 32.49 520 byte blocks. Was there any thought about tying this to the block size that a storage device was formatted for?

This value is expressed in increments of 512 bytes (i.e., a value of one means 512 bytes, two means 1 024 bytes, etc.). The relationship, if any, between data transfer operations and interconnect tenancies is defined in the individual SCSI transport protocol standards. A value of zero specifies there is no limit on the amount of data transferred per data transfer operation. This works for devices that formatted for data in multiples of 512 bytes per block; however, this does not map well for devices that formatted for Protection information and the block size is 520 bytes. I understand that the data transfer length can be easily compared to number of 512 byte blocks; however, if you want to have a max burst size of 32 blocks that are 520 bytes each then this field does not easily map to the number that you want because 33 would map to 32.49 520 byte blocks.

Another choice might be to add something in SBC that further clarifies the SPC text, and more specifically states that the value in that field represents "user data". Or, in SBC, you could say: If protection information is enabled, then this value is expressed in increments... If protection information is not enabled, then this value is expressed in increments... Either way, it sounds like we'll be seeing a proposal at the next meeting to suggest how to deal with this issue.

I belive MAXIMUM BURST SIZE and FIRST BURST SIZE should be specified the same way. FIRST BURST SIZE is also specified in 512-byte increments. The question is, does the burst size (FIRST or MAXIMUM) have more to do with the blocksize or the transport. SAS has a maximum frame payload of 1024 bytes, so a FIRST BURST SIZE set to a value that is a multiple of 2 (times 512) works nicely, regardless of the underlying blocksize. Would parameter rounding be a way to deal with this for target devices that prefer to align bursts on block boundaries with DIF? Another issue - a device that supports transferring DIF is also required to support legacy commands (xxPROTECT = 0) that do not transfer DIF fields. Is the maximum burst size going to be different for one command versus another, depending on the setting of xxPROTECT? I think what this means is the burst size is more tightly coupled to the requirements of the transport rather than the granularity of blocks within the device. 512 seemed like a reasonable "minimum chunk" for specifying burst sizes. But maybe both should be specified in bytes? If it's a big enough issue, then the solution is proably to define a new bit (probably from the reserved byte 13) to specify that the burst sizes are specified in bytes rather than bits (or use the entire byte to specify a different value as the multiplier for burst size, with a value of zero meaning 512).

I belive MAXIMUM BURST SIZE and FIRST BURST SIZE should be specified the same way. FIRST BURST SIZE is also specified in 512-byte increments. The question is, does the burst size (FIRST or MAXIMUM) have more to do with the blocksize or the transport. SAS has a maximum frame payload of 1024 bytes, so a FIRST BURST SIZE set to a value that is a multiple of 2 (times 512) works nicely, regardless of the underlying blocksize. Would parameter rounding be a way to deal with this for target devices that prefer to align bursts on block boundaries with DIF? Another issue - a device that supports transferring DIF is also required to support legacy commands (xxPROTECT = 0) that do not transfer DIF fields. Is the maximum burst size going to be different for one command versus another, depending on the setting of xxPROTECT? I think what this means is the burst size is more tightly coupled to the requirements of the transport rather than the granularity of blocks within the device. 512 seemed like a reasonable "minimum chunk" for specifying burst sizes. But maybe both should be specified in bytes? If it's a big enough issue, then the solution is proably to define a new bit (probably |from the reserved byte 13) to specify that the burst sizes are specified in bytes rather than bits (or use the entire byte to specify a different value as the multiplier for burst size, with a value of zero meaning 512).

The problem is that "user data" is defined in SBC, not in SPC, but here is the idea: The MAXIMUM BURST SIZE field indicates the maximum amount of data that the target port shall transfer during a single data transfer operation. This value is expressed in increments of 512 bytes (i.e., a value of one means 512 bytes , two means 1 024 bytes , etc.).

A value of zero specifies there is no limit on the amount of data transferred per data transfer operation. The issue of course, is that "user data" is defined in SBC (and relates to protection information that is defined in SBC), but the above text is from SPC (where "user data" is not defined, and there is no concept of protection information). Another choice might be to add something in SBC that further clarifies the SPC text, and more specifically states that the value in that field represents "user data". Or, in SBC, you could say: If protection information is enabled, then this value is expressed in increments... If protection information is not enabled, then this value is expressed in increments... Either way, it sounds like we'll be seeing a proposal at the next meeting to suggest how to deal with this issue.

Each 512-byte burst increment counts bytes of frame payload, whether it's a DIF-enabled READ/WRITE, a legacy READ/WRITE, or some other command like MODE SENSE or WRITE BUFFER. DIF (if present) is part of the frame payload (the transport layer doesn't know if DIF is present or not), and so DIF counts towards the 512 bytes of the burst increment it falls within. So, for example, if the device is formatted to 512+DIF (520 total per block), and a WRITE(10) command specifies WRPROTECT = 001b (transfer DIF), the first burst increment transferred contains 512 bytes for the first block specified, and the second burst increment contains the 8-bytes of DIF for the first block, and the first 504 bytes of the second block, etc... FIRST BURST SIZE and MAXIMUM BURST SIZE should be specified the same way. Implementations that support first burst size are no doubt implemented so as to count bytes of frame payload (which includes DIF) as part of the burst count. If the standard were modified to force larger (frame payload) bursts when DIF is present, it would likely break some existing implementations, so that is not a reasonable path to take.

There is no count field in the STANDBY IMMEDIATE command, but there is nothing to indicate that the timer is disabled when the device transitions back to active. The SCSI command requires that the timer be disabled until another START STOP UNIT command is received.
