+# Руководство по составлению каталога лотов СХД
+
+## Что такое LOT и зачем он нужен
+
+LOT — это внутренний идентификатор типа компонента в системе QuoteForge.
+
+Каждый LOT представляет одну рыночную позицию и хранит **средневзвешенную рыночную цену**, рассчитанную по историческим данным от поставщиков. Это позволяет получать актуальную оценку стоимости независимо от конкретного поставщика или прайс-листа.
+
+Партномера вендора (Part Number, Feature Code) сами по себе не имеют цены в системе — они **переводятся в LOT** через книгу партномеров. Именно через LOT происходит расценка конфигурации.
+
+**Пример:** Feature Code `B4B9` и Part Number `4C57A14368` — это два разных обозначения одной и той же HIC-карты от Lenovo. Оба маппируются на один LOT `HIC_4pFC32`, у которого есть рыночная цена.
+
+---
+
+## Категории и вкладки конфигуратора
+
+Категория LOT определяет, в какой вкладке конфигуратора он появится.
+
+| Код категории | Название | Вкладка | Что сюда относится |
+|---|---|---|---|
+| `ENC` | Storage Enclosure | **Base** | Дисковая полка без контроллера |
+| `DKC` | Disk/Controller Enclosure | **Base** | Контроллерная полка: модель СХД + тип дисков + кол-во слотов + кол-во контроллеров |
+| `CTL` | Storage Controller | **Base** | Контроллер СХД: объём кэша + встроенные хост-порты |
+| `HIC` | Host Interface Card | **PCI** | HIC-карты СХД: интерфейсы подключения (FC, iSCSI, SAS) |
+| `HDD` | HDD | **Storage** | Жёсткие диски (HDD) |
+| `SSD` | SSD | **Storage** | Твердотельные диски (SSD, NVMe) |
+| `ACC` | Accessories | **Accessories** | Кабели подключения, кабели питания |
+| `SW` | Software | **SW** | Программные лицензии |
+| *(прочее)* | — | **Other** | Гарантийные опции, инсталляция |
+
+---
+
+## Правила именования LOT
+
+Формат: `КАТЕГОРИЯ_МОДЕЛЬСХД_СПЕЦИФИКА`
+
+- только латиница, цифры и знак `_`
+- регистр — ВЕРХНИЙ
+- без пробелов, дефисов, точек
+- каждый LOT уникален — два разных компонента не могут иметь одинаковое имя
+
+### DKC — контроллерная полка
+
+Специфика: `ТИПДИСКА_СЛОТЫ_NCTRL`
+
+| Пример | Расшифровка |
+|---|---|
+| `DKC_DE4000H_SFF_24_2CTRL` | DE4000H, 24 слота SFF (2.5"), 2 контроллера |
+| `DKC_DE4000H_LFF_12_2CTRL` | DE4000H, 12 слотов LFF (3.5"), 2 контроллера |
+| `DKC_DE4000H_SFF_24_1CTRL` | DE4000H, 24 слота SFF, 1 контроллер (симплекс) |
+
+Обозначения типа диска: `SFF` — 2.5", `LFF` — 3.5", `NVMe` — U.2/U.3.
+
+### CTL — контроллер
+
+Специфика: `КЭШГБ_ПОРТЫТИП` (если встроенные порты есть) или `КЭШГБ_BASE` (если без портов, добавляются через HIC)
+
+| Пример | Расшифровка |
+|---|---|
+| `CTL_DE4000H_32GB_BASE` | 32GB кэш, без встроенных хост-портов |
+| `CTL_DE4000H_8GB_BASE` | 8GB кэш, без встроенных хост-портов |
+| `CTL_MSA2060_8GB_ISCSI10G_4P` | 8GB кэш, встроенные 4× iSCSI 10GbE |
+
+### HIC — HIC-карты (интерфейс подключения)
+
+Специфика: `NpПРОТОКОЛ` — без привязки к модели СХД, по аналогии с серверными `HBA_2pFC16`, `HBA_4pFC32_Gen6`.
+
+| Пример | Расшифровка |
+|---|---|
+| `HIC_4pFC32` | 4 порта FC 32Gb |
+| `HIC_4pFC16` | 4 порта FC 16G/10GbE |
+| `HIC_4p25G_iSCSI` | 4 порта 25G iSCSI |
+| `HIC_4p12G_SAS` | 4 порта SAS 12Gb |
+| `HIC_2p10G_BaseT` | 2 порта 10G Base-T |
+
+### HDD / SSD / NVMe — диски
+
+Диски **не привязываются к модели СХД** — используются существующие LOT из серверного каталога (`HDD_...`, `SSD_...`, `NVME_...`). Новые LOT для дисков СХД не создаются; партномера дисков маппируются на уже существующие серверные LOT.
+
+### ACC — кабели
+
+Кабели **не привязываются к модели СХД**. Формат: `ACC_CABLE_{ТИП}_{ДЛИНА}` — универсальные LOT, одинаковые для серверов и СХД.
+
+| Пример | Расшифровка |
+|---|---|
+| `ACC_CABLE_CAT6_10M` | Кабель CAT6 10м |
+| `ACC_CABLE_FC_OM4_3M` | Кабель FC LC-LC OM4 до 3м |
+| `ACC_CABLE_PWR_C13C14_15M` | Кабель питания C13–C14 1.5м |
+
+### SW — программные лицензии
+
+Специфика: краткое название функции.
+
+| Пример | Расшифровка |
+|---|---|
+| `SW_DE4000H_ASYNC_MIRROR` | Async Mirroring |
+| `SW_DE4000H_SNAPSHOT_512` | Snapshot 512 |

Mikhail Chusavitin	4bc7979a70	Remove obsolete storage components guide docx	2026-04-15 18:58:10 +03:00

Mikhail Chusavitin	aea6bf91ab	fix: abbreviate GPU architecture suffixes in article token Ampere, Hopper, Blackwell now produce AMP/HOP/BWL suffixes (like ADA) so RTX cards across generations are distinguishable: RTX6000ADA vs RTX6000BWL. LOVELACE remains a skip token as it duplicates ADA info. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-09 15:08:47 +03:00
Mikhail Chusavitin	d58d52c5e7	fix: include model number and ADA suffix in GPU article token RTX 6000 ADA and A6000 are distinct cards — RTX_4000_ADA_SFF now produces RTX4000ADA instead of RTX, avoiding visual ambiguity with the segment separator (10xRTX4000ADA vs 10xRTX-1x…).

Mikhail Chusavitin	7a628deb8a	feat: add СХД configuration type with storage-specific tabs and LOT catalog guide - Add config_type field ("server"\|"storage") to Configuration and LocalConfiguration - Create modal: Сервер/СХД segmented control in configs.html and project_detail.html - Configurator: ENC/DKC/CTL categories in Base tab, HIC section in PCI tab hidden for server configs - Add SW tab (categories: SW) to configurator, visible only when components present - TAB_CONFIG.pci: add HIC section for storage HIC adapters (separate from server HBA/NIC) - Migration 029: ALTER TABLE qt_configurations ADD COLUMN config_type - Fix: skip Error 1833 (Cannot change column used in FK) in GORM AutoMigrate - Operator guide: docs/storage-components-guide.md with LOT naming rules and DE4000H catalog template Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-08 18:01:23 +03:00
Mikhail Chusavitin	7f6be786a8	feat: redesign project pricing export — FOB/DDP basis, variant filename, article column - Add FOB/DDP basis to export options; DDP multiplies all prices ×1.3 - Rename export file from "pricing" to "{FOB\|DDP} {variant}" (e.g. "FOB v1") - Fix server article missing from CSV summary row (PN вендора column) - Skip per-row breakdown when neither LOT nor BOM is selected - Remove empty separator rows between configurations - Redesign export modal: split into Артикул / Цены / Базис поставки sections Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-03 17:55:26 +03:00
Mikhail Chusavitin	a360992a01	perf: enable WAL mode, batch price lookup, add DB diagnostics to schema_state - Set PRAGMA journal_mode=WAL + synchronous=NORMAL on SQLite open; eliminates read blocking during background pricelist sync writes - Replace N+1 per-lot price loop in QuoteService local fallback with GetLocalPricesForLots batch query (120 queries → 3 per price-levels call) - Add CountAllPricelistItems, CountComponents, DBFileSizeBytes to LocalDB - Report local_pricelist_count, pricelist_items_count, components_count, db_size_bytes in qt_client_schema_state for performance diagnostics Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-02 10:53:36 +03:00
