How do you freeze usable terabytes on a Dell PowerProtect DD9910 quote?

Quick Take

Quick Take: A DD9910 Active Tier tops out at 1,536 TB usable in Dell’s DDOS 8.0 table, starting from six 8 TB disk packs. The 157.5 PB figure is a ~75:1 logical estimate, not the disk you bought. Cloud Tier is a separate license and four metadata packs. For China enterprise RFQs, freeze usable TB on the equal brief before you ask for 13% VAT special fapiao pricing.

What a DD9910 Quote Is (and Is Not)

Definition: Dell PowerProtect Data Domain DD9910 is a high-capacity dedupe backup appliance in the PowerProtect Data Domain family (sibling DD9410; flash variant DD9910F). It is not a primary NAS array, and it is not a StoreOnce SKU. Think of logical PB marketing like a “compressed suitcase” claim — the usable TB on Active Tier is the suitcase volume you actually purchased.

Active Tier CPU is a 52-core 300 W Intel 8470N with 2048 GB memory (32 × 64 GB DDR5 RDIMM). Front SSDs: 10 × 3.84 TB. Shelves Dell names: DS600 (SAS) and FS240 (SSD). Cache Tier on DD9910 does not need a separate license; capacity expansion does need a capacity license before the shelf lands.

Fit: multi-site backup targets that need more than about 576 TB usable and a dedupe appliance footprint.

Unfit: primary NAS workloads, or backup jobs that fit a DD6410 / DD9410 envelope — do not overbuy packs for a shelf that never fills.

Capacity Numbers Buyers Must Freeze

Quick Answer: Freeze Active Tier usable TB (up to 1,536 TB in the DDOS 8.0 table), disk pack count (6–16), Cloud Tier usable (up to 3,072 TB) plus four metadata packs, and keep marketing logical PB off the PO line.

Item	Published figure	Buyer action
Active Tier max usable (DDOS 8.0)	1,536 TB	Write this as the capacity ceiling on the RFQ
Active Tier packs	6 min / 16 max (8 TB drives)	90–240 disks; do not invent pack SKUs
Cloud Tier usable	up to 3,072 TB	Separate license + 4 metadata packs
Cloud Tier metadata	480 TB raw / 384 TB usable	Four packs — miss this and Cloud Tier fails
Shop card usable band	576 TB–2.1 PB (+ Cloud Tier up to 5 PB)	Marketing band; confirm config on quote
Logical capacity claim	up to 157.5 PB (Cloud Tier up to 375 PB)	~75:1 estimate — not purchased retention
Memory / front SSD	2048 GB / 10×3.84 TB	Confirm on dated configuration

• Networking on the shop card: 1 management + 2 LOM required; rNDC/OCP options include 4×10GBASE-T or 4×10/25G SFP+; optional up to four 10GBASE-T, four quad 10/25G SFP28, four dual 100G QSFP, or four quad 32G FC HBA.
• HA: Dell publishes a DD9410/DD9910 installation, storage expansion, and HA upgrade guide — quote interconnect and support years with the chassis.
• No public net price on this page. Soft channel corridors stay industry estimate / pending confirmation.

DD9910 vs DD9410 Pack Math

Quick Answer: DD9410 Active Tier is 2–8 packs; DD9910 is 6–16 packs. Copying a DD9410 shelf count onto a DD9910 quote either underfills the minimum or invents an illegal mid-range. Compare usable TB and pack floors, not model nicknames.

Dimension	DD9910	DD9410 (contrast)
Active Tier packs	6–16	2–8
Disks at min / max	90 / 240	Lower floor — do not paste here
Drive size (Active)	8 TB	Confirm on DD9410 sheet separately
Use when	>~576 TB usable targets	Smaller backup targets

This page is a DD9910 ordering memo. Dual-path sizing against HPE StoreOnce 5660 belongs on a separate compare brief — do not mix StoreOnce shelf math into a DD9910 PO.

BOM Checklist Before PO

Quick Answer: Chassis + Active Tier packs + capacity license + optional Cloud Tier license/metadata packs + network options + HA interconnect + support years. Missing the capacity license before expansion is the classic dock failure.

• Model line: PowerProtect Data Domain DD9910 (or DD9910F if flash path is intentional).
• Active Tier usable TB + pack count (6–16).
• Capacity license covering the usable TB you intend to present.
• Cloud Tier: license + four metadata packs — or explicit “no Cloud Tier”.
• DS600 / FS240 shelves as named by Dell — no invented shelf SKUs.
• Network: management, LOM, rNDC/OCP, optional 100G/FC as required.
• HA upgrade materials if dual-node is in scope.
• Support years and any Cloud Tier entitlement on the same equal brief for 双规比选.

HowTo: Freeze a DD9910 BOM Before Purchase Order

Quick Answer: Lock usable TB, pack count, Cloud Tier lines, capacity license, and network/HA options before any channel price confirmation or 13% VAT special fapiao request.

1. Step 1 — Freeze usable TB. Write Active Tier usable TB from the DDOS table, not the marketing logical PB.
2. Step 2 — Count disk packs. Confirm 6–16 Active Tier packs of 8 TB drives; never paste a DD9410 pack count.
3. Step 3 — Separate Cloud Tier. If Cloud Tier is required, add license + four metadata packs as their own lines.
4. Step 4 — License before shelf. Capacity license for the new usable capacity must exist before the shelf is added.
5. Step 5 — Network and HA lines. Lock management + LOM + rNDC/OCP options; if HA, quote interconnect per Dell HA guide.
6. Step 6 — Equal brief for dual-path bid. Freeze the equal BOM for 双规比选 before channel price confirmation.

Real-World Deployment Scenarios

Quick Answer: Three scenes fail differently: a multi-site backup that treats 157.5 PB as purchased retention, a Cloud Tier add that forgets metadata packs, and an expansion that adds DS600 shelves before the capacity license.

1) Multi-site backup target — usable TB freeze

Ops needs retention across two data centers. Buyer pastes the shop-card logical PB into the scoring table. At acceptance, Active Tier usable is far below the logical claim. Fix: freeze 1,536 TB ceiling and the configured usable TB on the equal brief before dual-path bid scoring.

2) Cloud Tier metadata miss

Architecture asks for Cloud Tier to stretch cold retention. Quote includes a Cloud Tier license but zero metadata packs. Install stalls. Fix: four metadata packs (480 TB raw / 384 TB usable) as mandatory Cloud Tier lines.

3) Expansion without capacity license

Year-two growth adds DS600 shelves. Hardware arrives; software refuses the new capacity. Fix: capacity license for the new usable TB must exist before the shelf is added — Dell’s HA/expansion guide sequence, not dock improvisation.
